The heating temperature from feed heating process is an impact to power plant efficiency or heat rate. Normally, the degradation of feed water heater that operated for a long time is effect to decrease plant efficiency or increase plant heat rate. For Mae Moh power plant, each unit operated more than 20 years. The degradation of the main equipment is effect of planting efficiency or heat rate. From the efficiency and heat rate analysis, Mae Moh power plant operated in high heat rate more than the commissioning period. Some of the equipment were replaced for improving plant efficiency and plant heat rates such as HP turbine and LP turbine that the result is increased plant efficiency by 5% and decrease plant heat rate by 1%. For the target of power generation plan that Mae Moh power plant must be operated more than 10 years. These work is focus on thermal efficiency analysis of feed water heater to compare with the commissioning data for find the way to improve the feed water heater efficiency that may effect to increase plant efficiency or decrease plant heat rate by use heat balance model simulation and economic value add (EVA) method to study the investment for replacing the new feed water heater and analyze how this project can stay above the break-even point to make the project decision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feed%20water%20heater" title="feed water heater">feed water heater</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant%20efficiency" title=" power plant efficiency"> power plant efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20heat%20rate" title=" plant heat rate"> plant heat rate</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20efficiency%20analysis" title=" thermal efficiency analysis"> thermal efficiency analysis</a> </p> <a href="https://publications.waset.org/abstracts/65534/thermal-efficiency-analysis-and-optimal-of-feed-water-heater-for-mae-moh-thermal-power-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65534.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12101</span> Technology Identification, Evaluation and Selection Methodology for Industrial Process Water and Waste Water Treatment Plant of 3x150 MWe Tufanbeyli Lignite-Fired Power Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cigdem%20Safak%20Saglam">Cigdem Safak Saglam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most thermal power plants use steam as working fluid in their power cycle. Therefore, in addition to fuel, water is the other main input for thermal plants. Water and steam must be highly pure in order to protect the systems from corrosion, scaling and biofouling. Pure process water is produced in water treatment plants having many several treatment methods. Treatment plant design is selected depending on raw water source and required water quality. Although working principle of fossil-fuel fired thermal power plants are same, there is no standard design and equipment arrangement valid for all thermal power plant utility systems. Besides that, there are many other technology evaluation and selection criteria for designing the most optimal water systems meeting the requirements such as local conditions, environmental restrictions, electricity and other consumables availability and transport, process water sources and scarcity, land use constraints etc. Aim of this study is explaining the adopted methodology for technology selection for process water preparation and industrial waste water treatment plant in a thermal power plant project located in Tufanbeyli, Adana Province in Turkey. Thermal power plant is fired with indigenous lignite coal extracted from adjacent lignite reserves. This paper addresses all above-mentioned factors affecting the thermal power plant water treatment facilities (demineralization + waste water treatment) design and describes the ultimate design of Tufanbeyli Thermal Power Plant Water Treatment Plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20power%20plant" title="thermal power plant">thermal power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=lignite%20coal" title=" lignite coal"> lignite coal</a>, <a href="https://publications.waset.org/abstracts/search?q=pretreatment" title=" pretreatment"> pretreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=demineralization" title=" demineralization"> demineralization</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodialysis" title=" electrodialysis"> electrodialysis</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=ash%20dampening" title=" ash dampening"> ash dampening</a> </p> <a href="https://publications.waset.org/abstracts/38609/technology-identification-evaluation-and-selection-methodology-for-industrial-process-water-and-waste-water-treatment-plant-of-3x150-mwe-tufanbeyli-lignite-fired-power-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38609.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">482</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12100</span> A Key Parameter in Ocean Thermal Energy Conversion Plant Design and Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongjian%20Gu">Yongjian Gu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ocean thermal energy is one of the ocean energy sources. It is a renewable, sustainable, and green energy source. Ocean thermal energy conversion (OTEC) applies the ocean temperature gradient between the warmer surface seawater and the cooler deep seawater to run a heat engine and produce a useful power output. Unfortunately, the ocean temperature gradient is not big. Even in the tropical and equatorial regions, the surface water temperature can only reach up to 28oC and the deep water temperature can be as low as 4oC. The thermal efficiency of the OTEC plants, therefore, is low. In order to improve the plant thermal efficiency by using the limited ocean temperature gradient, some OTEC plants use the method of adding more equipment for better heat recovery, such as heat exchangers, pumps, etc. Obviously, the method will increase the plant's complexity and cost. The more important impact of the method is the additional equipment needs to consume power too, which may have an adverse effect on the plant net power output, in turn, the plant thermal efficiency. In the paper, the author first describes varied OTEC plants and the practice of using the method of adding more equipment for improving the plant's thermal efficiency. Then the author proposes a parameter, plant back works ratio ϕ, for measuring if the added equipment is appropriate for the plant thermal efficiency improvement. Finally, in the paper, the author presents examples to illustrate the application of the back work ratio ϕ as a key parameter in the OTEC plant design and operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ocean%20thermal%20energy" title="ocean thermal energy">ocean thermal energy</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean%20thermal%20energy%20conversion%20%28OTEC%29" title=" ocean thermal energy conversion (OTEC)"> ocean thermal energy conversion (OTEC)</a>, <a href="https://publications.waset.org/abstracts/search?q=OTEC%20plant" title=" OTEC plant"> OTEC plant</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20back%20work%20ratio%20%CF%95" title=" plant back work ratio ϕ"> plant back work ratio ϕ</a> </p> <a href="https://publications.waset.org/abstracts/141985/a-key-parameter-in-ocean-thermal-energy-conversion-plant-design-and-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141985.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12099</span> An Overview of Thermal Storage Techniques for Solar Thermal Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talha%20Shafiq">Talha Shafiq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The traditional electricity operation in solar thermal plants is designed to operate on a single path initiating at power plant and executes at the consumer.

In this paper, towards mitigating secondary flow losses, a design optimization workflow is implemented for the casing geometry of a 1.5 stage axial flow turbine that improves the turbine isentropic efficiency. The improved turbine is used in an open thermodynamic gas cycle with regeneration and cogeneration. Performance estimates are obtained by the commercial software Cycle – Tempo. Design and off design conditions are considered as well as variations in inlet air temperature. Reductions in both the natural gas specific fuel consumption and in CO<sub>2</sub> emissions are predicted by using the gas turbine cycle fitted with the new casing design. These gains are attractive towards enhancing the competitiveness and reducing the environmental impact of thermal power plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20flow%20turbine" title="axial flow turbine">axial flow turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine%20power%20plant" title=" gas turbine power plant"> gas turbine power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/93179/improving-the-performance-of-gas-turbine-power-plant-by-modified-axial-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93179.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12094</span> A Study on Cleaning Mirror Technology with Reduced Water Consumption in a Solar Thermal Power Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bayarjargal%20Enkhtaivan">Bayarjargal Enkhtaivan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gao%20Wei"> Gao Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20%20Yanping"> Zhang Yanping</a>, <a href="https://publications.waset.org/abstracts/search?q=He%20Guo%20Qiang"> He Guo Qiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In our study, traditional cleaning mirror technology with reduced consumption of water in solar thermal power plants is investigated. In developed countries, a significant increase of growth and innovation in solar thermal power sector is evident since over the last decade. These power plants required higher water consumption, however, there are some complications to construct and operate such power plants under severe drought-inflicted areas like deserts where high water-deficit can be seen but sufficient solar energy is available. Designing new experimental equipments is the most important advantage of this study. These equipments can estimate various types of measurements at the mean time. In this study, Glasses were placed for 10 and 20 days at certain positions to deposit dusts on glass surface by using a common method. Dust deposited on glass surface was washed by experimental equipment and measured dust deposition on each glass.

During their low-cost operations, the price of electricity significantly reduces to a lower value, and sometimes it becomes negative. Therefore, it is recommended not to operate the traditional power plants (e.g. coal power plants) and to reduce the losses. In fact, it is not a cost-effective solution, because these power plants exhibit some shutdown and startup costs. Moreover, they require certain time for shutdown and also need enough pause before starting up again, increasing inefficiency in the whole power network. Hence, there is always a trade-off between avoiding negative electricity prices, and the startup costs of power plants. To exploit this trade-off and to increase the profit of a power plant, two main contributions are made: 1) introducing retrofit technology for state of art coal power plant; 2) proposing optimal control strategy for a power plant by exploiting different flexibility features. These flexibility features include: improving ramp rate of power plant, reducing startup time and lowering minimum load. While, the control strategy is solved as mixed integer linear programming (MILP), ensuring optimal solution for the profit maximization problem. Extensive comparisons are made considering pre and post-retrofit coal power plant having the same efficiencies under different electricity price scenarios. It concludes that if the power plant must remain in the market (providing services), more flexibility reflects direct economic advantage to the plant operator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discrete%20optimization" title="discrete optimization">discrete optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant%20flexibility" title=" power plant flexibility"> power plant flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=profit%20maximization" title=" profit maximization"> profit maximization</a>, <a href="https://publications.waset.org/abstracts/search?q=unit%20commitment%20model" title=" unit commitment model"> unit commitment model</a> </p> <a href="https://publications.waset.org/abstracts/99691/maximizing-profit-using-optimal-control-by-exploiting-the-flexibility-in-thermal-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12092</span> Nuclear Power Plant Radioactive Effluent Discharge Management in China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jie%20Yang">Jie Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qifu%20Cheng"> Qifu Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yafang%20Liu"> Yafang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhijie%20Gu"> Zhijie Gu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Controlled emissions of effluent from nuclear power plants are an important means of ensuring environmental safety.

A reliability-centered maintenance (RCM) technique is an established method of analysis and is the main reference for maintenance planning. This method considers the consequences of failure in its implementation, but does not deal with further risk of down time that associated with failures, loss of production or high maintenance costs. Risk-based maintenance (RBM) technique provides support strategies to minimize the risks posed by the failure to obtain maintenance task considering cost effectiveness. Meanwhile, condition-based maintenance (CBM) focuses on monitoring the application of the conditions that allow the planning and scheduling of maintenance or other action should be taken to avoid the risk of failure prior to the time-based maintenance. Implementation of RCM, RBM, CBM alone or combined RCM and RBM or RCM and CBM is a maintenance technique used in thermal power plants. Implementation of these three techniques in an integrated maintenance will increase the availability of thermal power plants compared to the use of maintenance techniques individually or in combination of two techniques. This study uses the reliability, risks and conditions-based maintenance in an integrated manner to increase the availability of thermal power plants. The method generates MPI (Priority Maintenance Index) is RPN (Risk Priority Number) are multiplied by RI (Risk Index) and FDT (Failure Defense Task) which can generate the task of monitoring and assessment of conditions other than maintenance tasks. Both MPI and FDT obtained from development of functional tree, failure mode effects analysis, fault-tree analysis, and risk analysis (risk assessment and risk evaluation) were then used to develop and implement a plan and schedule maintenance, monitoring and assessment of the condition and ultimately perform availability analysis. The results of this study indicate that the reliability, risks and conditions-based maintenance methods, in an integrated manner can increase the availability of thermal power plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrated%20maintenance%20techniques" title="integrated maintenance techniques">integrated maintenance techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=availability" title=" availability"> availability</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20power%20plant" title=" thermal power plant"> thermal power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=MPI" title=" MPI"> MPI</a>, <a href="https://publications.waset.org/abstracts/search?q=FDT" title=" FDT "> FDT </a> </p> <a href="https://publications.waset.org/abstracts/26806/the-integrated-methodological-development-of-reliability-risk-and-condition-based-maintenance-in-the-improvement-of-the-thermal-power-plant-availability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26806.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">794</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12090</span> A Technical and Economic Feasibility Study of the Use of Concentrating Solar Power (CSP) in Desalination Plants on the Kenyan Coast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kathy%20Mwende%20Kiema">Kathy Mwende Kiema</a>, <a href="https://publications.waset.org/abstracts/search?q=Remember%20Samu"> Remember Samu</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Fahrioglu"> Murat Fahrioglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the implementation of a Feed in Tariff (FiT) for solar power plants in Kenya, the uptake and subsequent development of utility scale power plants has been slow. This paper, therefore, proposes a Concentrating Solar Power (CSP) plant configuration that can supply both power to the grid and operate a sea water desalination plant, thus providing an economically viable alternative to Independent Power Producers (IPPs). The largest city on the coast, Mombasa, has a chronic water shortage and authorities are looking to employ desalination plants to supply a deficit of up to 100 million cubic meters of fresh water per day. In this study the desalination plant technology was selected based on an analysis of operational costs in $/m3 of plants that are already running. The output of the proposed CSP plant, Net Present Value (NPV), plant capacity factor, thermal efficiency and quantity of CO2 emission avoided were simulated using Greenius software (Green energy system analysis tool) developed by the institute of solar research at the German Aerospace Center (DLR). Data on solar irradiance were derived from the Solar and Wind Energy Resource Assessment (SWERA) for Kenya. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desalination" title="desalination">desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20in%20tariff" title=" feed in tariff"> feed in tariff</a>, <a href="https://publications.waset.org/abstracts/search?q=independent%20power%20producer" title=" independent power producer"> independent power producer</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20CSP" title=" solar CSP"> solar CSP</a> </p> <a href="https://publications.waset.org/abstracts/65449/a-technical-and-economic-feasibility-study-of-the-use-of-concentrating-solar-power-csp-in-desalination-plants-on-the-kenyan-coast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65449.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12089</span> Shape Optimization of Header Pipes in Power Plants for Enhanced Efficiency and Environmental Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Cherif%20Megri">Ahmed Cherif Megri</a>, <a href="https://publications.waset.org/abstracts/search?q=HossamEldin%20ElSherif"> HossamEldin ElSherif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a power plant, the header pipe plays a pivotal role in optimizing the performance of diverse systems by serving as a central conduit for the collection and distribution of steam within the plant.

The concept of shape optimization emerges as a crucial factor in power plant design and operation, with the potential to maximize performance while minimizing the use of materials. Shape optimization not only enhances efficiency but also contributes to reducing the environmental footprint of power plant installations. In this paper, we initially developed a methodology designed for optimizing header shapes with the primary goal of reducing the usage of costly new alloy materials and lowering the overall maintenance operation expenses.

This study investigated the effect of variations of overall conductance of the super heater on the performance of an existing steam power plant located in Derna, Libya. The performance of the power plant was estimated by a mathematical modelling which considers the off-design operating conditions of each component. A fully interactive computer program based on the mass, energy and exergy balance equations has been developed. The maximum exergy destruction has been found in the steam generation unit. A 50% reduction in the design value of overall conductance of the super heater has been achieved, which accordingly decreases the amount of the net electrical power that would be generated by at least 13 MW, as well as the overall plant exergy efficiency by at least 6.4%, and at the same time that would cause an increase of the total exergy destruction by at least 14 MW. The achieved results showed that the super heater design and operating conditions play an important role on the thermodynamics performance and the fuel utilization of the power plant. Moreover, these considerations are very useful in the process of the decision that should be taken at the occasions of deciding whether to replace or renovate the super heater of the power plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Exergy" title="Exergy">Exergy</a>, <a href="https://publications.waset.org/abstracts/search?q=Super-heater" title=" Super-heater"> Super-heater</a>, <a href="https://publications.waset.org/abstracts/search?q=Fouling%3B%20Steam%20power%20plant%3B%20Off-design." title=" Fouling; Steam power plant; Off-design."> Fouling; Steam power plant; Off-design.</a>, <a href="https://publications.waset.org/abstracts/search?q=Fouling%3B" title=" Fouling;"> Fouling;</a>, <a href="https://publications.waset.org/abstracts/search?q=Super-heater" title=" Super-heater"> Super-heater</a>, <a href="https://publications.waset.org/abstracts/search?q=Steam%20power%20plant" title=" Steam power plant"> Steam power plant</a> </p> <a href="https://publications.waset.org/abstracts/60015/performance-of-derna-steam-power-plant-at-varying-super-heater-operating-conditions-based-on-exergy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60015.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12087</span> Thermodynamic Evaluation of Coupling APR-1400 with a Thermal Desalination Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Gomaa%20Abdoelatef">M.

Key elements of the economics of desalination projects are thermal and electrical inputs. With growing concerns over the use of fossil fuels to (indirectly) supply these inputs, coupling of desalination with nuclear power production represents a significant opportunity. Individually, nuclear and desalination technologies have a long history and are relatively mature. For desalination, Reverse Osmosis (RO) has the lowest energy inputs. However, the economically driven output quality of the water produced using RO, which uses only electrical inputs, is lower than the output water quality from thermal desalination plants. Therefore, modern desalination projects consider that RO should be coupled with thermal desalination technologies (MSF, MED, or MED-TVC) with attendant steam inputs to permit blending to produce various qualities of water. A large nuclear facility is well positioned to dispatch large quantities of both electrical and thermal power. This paper considers the supply of thermal energy to a large desalination facility to examine heat balance impact on the nuclear steam cycle. The APR1400 nuclear plant is selected as prototypical from both a capacity and turbine cycle heat balance perspective to examine steam supply and the impact on electrical output. Extraction points and quantities of steam are considered parametrically along with various types of thermal desalination technologies to form the basis for further evaluations of economically optimal approaches to the interface of nuclear power production with desalination projects. In our study, the thermodynamic evaluation will be executed by DE-TOP which is the IAEA desalination program, it is approved to be capable of analyzing power generation systems coupled to desalination systems through various steam extraction positions, taking into consideration the isolation loop between the APR-1400 and the thermal desalination plant for safety concern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=APR-1400" title="APR-1400">APR-1400</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=DE-TOP" title=" DE-TOP"> DE-TOP</a>, <a href="https://publications.waset.org/abstracts/search?q=IAEA" title=" IAEA"> IAEA</a>, <a href="https://publications.waset.org/abstracts/search?q=MSF" title=" MSF"> MSF</a>, <a href="https://publications.waset.org/abstracts/search?q=MED" title=" MED"> MED</a>, <a href="https://publications.waset.org/abstracts/search?q=MED-TVC" title=" MED-TVC"> MED-TVC</a>, <a href="https://publications.waset.org/abstracts/search?q=RO" title=" RO"> RO</a> </p> <a href="https://publications.waset.org/abstracts/32631/thermodynamic-evaluation-of-coupling-apr-1400-with-a-thermal-desalination-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32631.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">530</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12086</span> Availability Analysis of a Power Plant by Computer Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Savsar">Mehmet Savsar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reliability and availability of power stations are extremely important in order to achieve a required level of power generation.

The main objective of this paper is to investigate the effects of climate change on thermal power plants including gas turbines, steam and combined cycle power plants in Iran. For this purpose, the ambient temperature increase and water accessibility will be analyzed and their effects on power output and efficiency of thermal power plants will be determined. According to the results, the ambient temperature has high effect on steam power plants with indirect cooling system (Heller). The efficiency of this type of power plants decreases by 0.55 percent per 1oC ambient temperature increase. This amount is 0.52 and 0.2 percent for once-through and wet cooling systems, respectively. The decrease in power output covers a range of 0.2% to 0.65% for steam power plant with wet cooling system and gas turbines per 1oC air temperature increase. Based on the thermal power plants distribution in Iran and different scenarios of climate change, the total amount of power output decrease falls between 413 and 1661 MW due to ambient temperature increase. Another limitation incurred by climate change is water accessibility. In optimistic scenario, the power output of steam plants decreases by 1450 MW in dry and hot climate areas throughout next decades. The remaining scenarios indicate that the amount of decrease in power output would be by 4152 MW in highlands and cold climate. Therefore, it is necessary to consider appropriate solutions to overcome these limitations. Considering all the climate change effects together, the actual power output falls in range of 2465 and 7294 MW and efficiency loss covers the range of 0.12 to .56 % in different scenarios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate" title="climate">climate</a>, <a href="https://publications.waset.org/abstracts/search?q=change" title=" change"> change</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal" title=" thermal"> thermal</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plants" title=" power plants"> power plants</a> </p> <a href="https://publications.waset.org/abstracts/171232/the-study-of-climate-change-effects-on-the-performance-of-thermal-power-plants-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171232.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12084</span> Managing the Effects of Wet Coal on Generation in Thermal Power Station: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravindra%20Gohane">Ravindra Gohane</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20V.%20Deshmukh"> S.

Different types of coal are available for utilization. The moisture content, volatile nature and ash content determines the type of the coal. Out of these moisture plays a very important part as it is present naturally within the coal and is added while handling the coal and is termed as wet coal. The problems of wet coal are many and more particularly during rainy season such as generation loss, jamming of crusher, reduction in calorific value, transportation of coal etc. Efforts are made to resolve the problems arising out of wet coal worldwide. This paper highlights the issue of resolving the problem due to wet coal with the help of a case study involving installation of V-type wiper on the conveyer belt. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coal%20handling%20plant" title="coal handling plant">coal handling plant</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20coal" title=" wet coal"> wet coal</a>, <a href="https://publications.waset.org/abstracts/search?q=v-type" title=" v-type"> v-type</a>, <a href="https://publications.waset.org/abstracts/search?q=generation" title=" generation"> generation</a> </p> <a href="https://publications.waset.org/abstracts/66146/managing-the-effects-of-wet-coal-on-generation-in-thermal-power-station-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66146.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12083</span> Life Prediction of Condenser Tubes Applying Fuzzy Logic and Neural Network Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Majidian">A.

The heat recovery systems used in different parts of the plant are also considered in the analysis. Mass, thermal and exergy balances are established on the main compounds of the factory. A numerical code is established using EES software to perform the calculations required for the thermal and exergy plant analysis. The effects of the key operating parameters such as steam pressure and temperature, mass flow rate as well as seawater temperature, on the cycle performances are investigated. A maximum Exergy Loss Rate of about 72% is obtained for the melters, followed by the condensers, heat exchangers and the pumps. The heat exchangers used in the phosphoric acid unit present exergetic efficiencies around 33% while 60% to 72% are obtained for steam turbines and blower. For the explored ranges of HP steam temperature and pressure, the exergy efficiencies of steam turbine generators STGI and STGII increase of about 2.5% and 5.4% respectively. In the same way, optimum HP steam flow rate values, leading to the maximum exergy efficiencies are defined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steam%20turbine%20generator" title="steam turbine generator">steam turbine generator</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy%20efficiency" title=" exergy efficiency"> exergy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphoric%20acid%20plant" title=" phosphoric acid plant"> phosphoric acid plant</a> </p> <a href="https://publications.waset.org/abstracts/39804/exergetic-analysis-of-steam-turbine-power-plant-operated-in-chemical-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39804.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">310</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12081</span> The Techno-Economic Comparison of Solar Power Generation Methods for Turkish Republic of North Cyprus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dagbasi">Mustafa Dagbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Bamisile"> Olusola Bamisile</a>, <a href="https://publications.waset.org/abstracts/search?q=Adii%20Chinedum"> Adii Chinedum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work is to examine and compare the economic and environmental feasibility of 40MW photovoltaic (PV) power plant and 40MW parabolic trough (PT) power plant to be installed in two different cities, namely Nicosia and Famagusta in Turkish Republic of Northern Cyprus (TRNC). The need for using solar power technology around the world is also emphasized. Solar radiation and sunshine data for Nicosia and Famagusta are considered and analyzed to assess the distribution of solar radiation, sunshine duration, and air temperature. Also, these two different technologies with same rated power of 40MW will be compared with the performance of the proposed Solar Power Plant at Bari, Italy. The project viability analysis is performed using System Advisor Model (SAM) through Annual Energy Production and economic parameters for both cities. It is found that for the two cities; Nicosia and Famagusta, the investment is feasible for both 40MW PV power plant and 40MW PT power plant. From the techno-economic analysis of these two different solar power technologies having same rated power and under the same environmental conditions, PT plants produce more energy than PV plant. It is also seen that if a PT plant is installed near an existing steam turbine power plant, the steam from the PT system can be used to run this turbine which makes it more feasible to invest. The high temperatures that are used to produce steam for the turbines in the PT plant system can be supplemented with a secondary plant based on natural gas or other biofuels and can be used as backup. Although the initial investment of PT plant is higher, it has higher economic return and occupies smaller area compared to PV plant of the same capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20power" title="solar power">solar power</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20plant" title=" photovoltaic plant"> photovoltaic plant</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20trough%20plant" title=" parabolic trough plant"> parabolic trough plant</a>, <a href="https://publications.waset.org/abstracts/search?q=techno-economic%20analysis" title=" techno-economic analysis"> techno-economic analysis</a> </p> <a href="https://publications.waset.org/abstracts/47894/the-techno-economic-comparison-of-solar-power-generation-methods-for-turkish-republic-of-north-cyprus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47894.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12080</span> Engineering Thermal-Hydraulic Simulator Based on Complex Simulation Suite “Virtual Unit of Nuclear Power Plant”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evgeny%20Obraztsov">Evgeny Obraztsov</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilya%20Kremnev"> Ilya Kremnev</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitaly%20Sokolov"> Vitaly Sokolov</a>, <a href="https://publications.waset.org/abstracts/search?q=Maksim%20Gavrilov"> Maksim Gavrilov</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgeny%20Tretyakov"> Evgeny Tretyakov</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Kukhtevich"> Vladimir Kukhtevich</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Bezlepkin"> Vladimir Bezlepkin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the last decade, a specific set of connected software tools and calculation codes has been gradually developed. It allows simulating I&C systems, thermal-hydraulic, neutron-physical and electrical processes in elements and systems at the Unit of NPP (initially with WWER (pressurized water reactor)). In 2012 it was called a complex simulation suite “Virtual Unit of NPP” (or CSS “VEB” for short). Proper application of this complex tool should result in a complex coupled mathematical computational model. And for a specific design of NPP, it is called the Virtual Power Unit (or VPU for short). VPU can be used for comprehensive modelling of a power unit operation, checking operator's functions on a virtual main control room, and modelling complicated scenarios for normal modes and accidents. In addition, CSS “VEB” contains a combination of thermal hydraulic codes: the best-estimate (two-liquid) calculation codes KORSAR and CORTES and a homogenous calculation code TPP. So to analyze a specific technological system one can build thermal-hydraulic simulation models with different detalization levels up to a nodalization scheme with real geometry. And the result at some points is similar to the notion “engineering/testing simulator” described by the European utility requirements (EUR) for LWR nuclear power plants. The paper is dedicated to description of the tools mentioned above and an example of the application of the engineering thermal-hydraulic simulator in analysis of the boron acid concentration in the primary coolant (changed by the make-up and boron control system). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=best-estimate%20code" title="best-estimate code">best-estimate code</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20simulation%20suite" title=" complex simulation suite"> complex simulation suite</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20simulator" title=" engineering simulator"> engineering simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant" title=" power plant"> power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20hydraulic" title=" thermal hydraulic"> thermal hydraulic</a>, <a href="https://publications.waset.org/abstracts/search?q=VEB" title=" VEB"> VEB</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20power%20unit" title=" virtual power unit"> virtual power unit</a> </p> <a href="https://publications.waset.org/abstracts/63791/engineering-thermal-hydraulic-simulator-based-on-complex-simulation-suite-virtual-unit-of-nuclear-power-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63791.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12079</span> A Life Cycle Assessment (LCA) of Aluminum Production Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Al%20Hawari">Alaa Al Hawari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Khader"> Mohammad Khader</a>, <a href="https://publications.waset.org/abstracts/search?q=Wael%20El%20Hasan"> Wael El Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Alijla"> Mahmoud Alijla</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Manawi"> Ammar Manawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelbaki%20Benamour"> Abdelbaki Benamour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The production of aluminium alloys and ingots -starting from the processing of alumina to aluminium, and the final cast product- was studied using a Life Cycle Assessment (LCA) approach. The studied aluminium supply chain consisted of a carbon plant, a reduction plant, a casting plant, and a power plant. In the LCA model, the environmental loads of the different plants for the production of 1 ton of aluminium metal were investigated. The impact of the aluminium production was assessed in eight impact categories. The results showed that for all of the impact categories the power plant had the highest impact only in the cases of Human Toxicity Potential (HTP) the reduction plant had the highest impact and in the Marine Aquatic Eco-Toxicity Potential (MAETP) the carbon plant had the highest impact. Furthermore, the impact of the carbon plant and the reduction plant combined was almost the same as the impact of the power plant in the case of the Acidification Potential (AP). The carbon plant had a positive impact on the environment when it comes to the Eutrophication Potential (EP) due to the production of clean water in the process. The natural gas based power plant used in the case study had 8.4 times less negative impact on the environment when compared to the heavy fuel based power plant and 10.7 times less negative impact when compared to the hard coal based power plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title="life cycle assessment">life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium%20production" title=" aluminium production"> aluminium production</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20impacts" title=" ecological impacts"> ecological impacts</a> </p> <a href="https://publications.waset.org/abstracts/8005/a-life-cycle-assessment-lca-of-aluminum-production-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8005.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">532</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12078</span> Determining the City Development Based on the Modeling of the Pollutant Emission from Power Plant by Using AERMOD Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abbasi%20Fakhrossadat">Abbasi Fakhrossadat</a>, <a href="https://publications.waset.org/abstracts/search?q=Moharreri%20Mohammadamir"> Moharreri Mohammadamir</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadmanmahani%20Mohammadjavad"> Shadmanmahani Mohammadjavad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of cities can be influenced by various factors, including air pollution.

Fly ash is spread and distributed in the surrounding area by air and may be deposited on the soil of the region surrounding the power plant. Coal contains increased levels of these radionuclides and fly ash may increase the radioactivity in the soil around the power plant. Radon atoms entering into the pore space from the mineral grain are transported by diffusion and advection through this space until they in turn decay or are released into the atmosphere. In the present study, Soil samples were collected from the region around a Kasimpur Thermal Power Plant, Kasimpur, Aligarh (U.P.). Radon activity, radon surface exhalation and mass exhalation rates were measured using “sealed can technique” using LR 115-type II nuclear track detectors. Radon activities vary from 92.9 to 556.8 Bq m-3 with mean value of 279.8 Bq m-3. Surface exhalation rates (EX) in these samples are found to vary from 33.4 to 200.2 mBq m-2 h-1 with an average value of 100.5 mBq m-2 h-1 whereas, Mass exhalation rates (EM) vary from 1.2 to 7.7 mBq kg-1 h-1 with an average value of 3.8 mBq kg-1 h-1. Activity concentrations of radionuclides were measured in these samples by using a low level NaI (Tl) based gamma ray spectrometer. Activity concentrations of 226Ra 232Th and 40K vary from 12 to 49 Bq kg-1, 24 to 49 Bq kg-1 and 135 to 546 Bq kg-1 with overall mean values of 30.3 Bq kg-1, 38.5 Bq kg-1 and 317.8 Bq kg-1, respectively. Radium equivalent activity has been found to vary from 80.0 to 143.7 Bq kg-1 with an average value of 109.7 Bq kg-1.

In most efficient plants, hot water and air are generated from the steam supply system. Research has shown that thermal energy utilize in palm oil production plants is about 70 percent of the total energy consumption of the plant. In order to manage the plants’ energy efficiently, the energy systems are modelled and optimized. This paper aimed to present the model of steam supply systems of a typical palm oil production plant in Ghana. The models include exergy and energy models of steam boiler, steam turbine and the palm oil mill. The paper further simulates the virtual plant model to obtain the thermal energy performance of the plant under study. The simulation results show that, under normal operating condition, the boiler energy performance is considerably below the expected level as a result of several factors including intermittent biomass fuel supply, significant moisture content of the biomass fuel and significant heat losses. The total thermal energy performance of the virtual plant is set as a baseline. The study finally recommends number of energy efficiency measures to improve the plant’s energy performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20biomass" title="palm biomass">palm biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=steam%20supply" title=" steam supply"> steam supply</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy%20and%20energy%20models" title=" exergy and energy models"> exergy and energy models</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20performance%20benchmark" title=" energy performance benchmark"> energy performance benchmark</a> </p> <a href="https://publications.waset.org/abstracts/78554/modeling-and-benchmarking-the-thermal-energy-performance-of-palm-oil-production-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78554.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">349</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12075</span> An Investigation of System and Operating Parameters on the Performance of Parabolic Trough Solar Collector for Power Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umesh%20Kumar%20Sinha">Umesh Kumar Sinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Y.%20K.%20Nayak"> Y.

The effects of system and operating parameters were investigated using the developed mathematical expressions for collector efficiency, heat removal factor, fluid outlet temperature and power, etc. The results were simulated using C++program. The simulated results were plotted for investigation like effect of thermal loss parameter and radiative loss parameters on the collector efficiency, heat removal factor, fluid outlet temperature, rise of temperature and effect of mass flow rate of the fluid outlet temperature. In connection with the power generation, plots were drawn for the effect of (TM–TAMB) on the variation of concentration efficiency, concentrator irradiance on PM/PMN, evaporation temperature on thermal to electric power efficiency (Conversion efficiency) of the plant and overall efficiency of solar power plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parabolic%20trough%20solar%20collector" title="parabolic trough solar collector">parabolic trough solar collector</a>, <a href="https://publications.waset.org/abstracts/search?q=radiative%20and%20thermal%20loss%20parameters" title=" radiative and thermal loss parameters"> radiative and thermal loss parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=collector%20efficiency" title=" collector efficiency"> collector efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20removal%20factor" title=" heat removal factor"> heat removal factor</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20outlet%20and%20inlet%20temperatures" title=" fluid outlet and inlet temperatures"> fluid outlet and inlet temperatures</a>, <a href="https://publications.waset.org/abstracts/search?q=rise%20of%20temperature" title=" rise of temperature"> rise of temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20flow%20rate" title=" mass flow rate"> mass flow rate</a>, <a href="https://publications.waset.org/abstracts/search?q=conversion%20efficiency" title=" conversion efficiency"> conversion efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=concentrator%20irradiance" title=" concentrator irradiance"> concentrator irradiance</a> </p> <a href="https://publications.waset.org/abstracts/74875/an-investigation-of-system-and-operating-parameters-on-the-performance-of-parabolic-trough-solar-collector-for-power-generation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74875.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">321</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12074</span> Modelling and Simulation of Natural Gas-Fired Power Plant Integrated to a CO2 Capture Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebuwa%20Osagie">Ebuwa Osagie</a>, <a href="https://publications.waset.org/abstracts/search?q=Chet%20Biliyok"> Chet Biliyok</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeung%20Hoi"> Yeung Hoi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Regeneration energy requirement and ways to reduce it is the main aim of most CO2 capture researches currently being performed and thus, post-combustion carbon capture (PCC) option is identified to be the most suitable for the natural gas-fired power plants. From current research and development (R&D) activities worldwide, two main areas are being examined in order to reduce the regeneration energy requirement of amine-based PCC, namely: (a) development of new solvents with better overall performance than 30wt% monoethanolamine (MEA) aqueous solution, which is considered as the base-line solvent for solvent-based PCC, (b) Integration of the PCC Plant to the power plant. In scaling-up a PCC pilot plant to the size required for a commercial-scale natural gas-fired power plant, process modelling and simulation is very essential. In this work, an integrated process made up of a 482MWe natural gas-fired power plant, an MEA-based PCC plant which is developed and validated has been modelled and simulated. The PCC plant has four absorber columns and a single stripper column, the modelling and simulation was performed with Aspen Plus® V8.4. The gas turbine, the heat recovery steam generator and the steam cycle were modelled based on a 2010 US DOE report, while the MEA-based PCC plant was modelled as a rate-based process. The scaling of the amine plant was performed using a rate based calculation in preference to the equilibrium based approach for 90% CO2 capture. The power plant was integrated to the PCC plant in three ways: (i) flue gas stream from the power plant which is divided equally into four stream and each stream is fed into one of the four absorbers in the PCC plant. (ii) Steam draw-off from the IP/LP cross-over pipe in the steam cycle of the power plant used to regenerate solvent in the reboiler. (iii) Condensate returns from the reboiler to the power plant. The integration of a PCC plant to the NGCC plant resulted in a reduction of the power plant output by 73.56 MWe and the net efficiency of the integrated system is reduced by 7.3 % point efficiency. A secondary aim of this study is the parametric studies which have been performed to assess the impacts of natural gas on the overall performance of the integrated process and this is achieved through investigation of the capture efficiencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20gas-fired" title="natural gas-fired">natural gas-fired</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant" title=" power plant"> power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=MEA" title=" MEA"> MEA</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20capture" title=" CO2 capture"> CO2 capture</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/36464/modelling-and-simulation-of-natural-gas-fired-power-plant-integrated-to-a-co2-capture-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36464.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12073</span> Study of Current the Rice Straw Potential for a Small Power Plant Capacity in the Central Region of Thailand </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sansanee%20Sansiribhan">Sansanee Sansiribhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Orrawan%20Rewthong"> Orrawan Rewthong</a>, <a href="https://publications.waset.org/abstracts/search?q=Anusorn%20Rattanathanaophat"> Anusorn Rattanathanaophat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarun%20Saensiriphan"> Sarun Saensiriphan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work was to study potential of rice straw for power plant in the central region of Thailand.
