Steam produced by the boiler is used for various processes in the plant such as urea and ammonia plant. An alternative method to optimize the boiler combustion system is presented in this paper. Adaptive Neuro-Fuzzy Inference System (ANFIS) approach is applied to model the boiler using real-time operational data collected from a boiler unit of the petrochemical plant. Nonlinear equation obtained is then used to optimize the air to fuel ratio using Genetic Algorithm, resulting an optimal ratio of 15.85. This optimal ratio is then maintained constant by ratio controller designed using inverse dynamics based on ANFIS. As a result, constant value of oxygen content in the flue gas is obtained which indicates more efficient combustion process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANFIS" title="ANFIS">ANFIS</a>, <a href="https://publications.waset.org/abstracts/search?q=boiler" title=" boiler"> boiler</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20process" title=" combustion process"> combustion process</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization." title=" optimization.

The air pollution caused by the operation of heating devices using solid fuels is a significant problem. In order to improve the air quality, heating device producers take constant measures to improve their products. However, the emission results achieved during an initial test of heating devices in the laboratory may be much worse during operation in real operating conditions. The ways of increasing the efficiency of the boiler by improving its design for combustion in full-layer mode are shown. The results of the testing of the improved КВТС-0.2 hot water boiler is presented and the technical and economic indicators are determined, which indicate an increase in the efficiency of the boiler. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boiler%20unit" title="boiler unit">boiler unit</a>, <a href="https://publications.waset.org/abstracts/search?q=grate" title=" grate"> grate</a>, <a href="https://publications.waset.org/abstracts/search?q=furnace" title=" furnace"> furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=coal" title=" coal"> coal</a>, <a href="https://publications.waset.org/abstracts/search?q=ash" title=" ash"> ash</a> </p> <a href="https://publications.waset.org/abstracts/152536/new-scheme-of-control-and-air-supply-in-a-low-power-hot-water-boiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152536.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">70</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">647</span> Steady State Modeling and Simulation of an Industrial Steam Boiler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Lyria%20Deghal%20Cheridi">Amina Lyria Deghal Cheridi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abla%20Chaker"> Abla Chaker</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahcene%20Loubar"> Ahcene Loubar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Relap5 system code is one among powerful tools, which is used in the area of design and safety evaluation. This work aims to simulate the behavior of a radiant steam boiler at the steady-state conditions using Relap5 code system. To perform this study, a detailed Relap5 model is built including all the parts of the steam boiler. The control and regulation systems are also considered. To reproduce the most important parameters and phenomena with an acceptable accuracy and fidelity, a strong qualification work is undertaken concerning the facility nodalization. It consists of making a comparison between the code results and the plant available data in steady-state operation mode. Therefore, the model qualification results at the steady-state are in good agreement with the steam boiler experimental data. The steam boiler Relap5 model has proved satisfactory; and the model was capable of predicting the main thermal-hydraulic steady-state conditions of the steam boiler. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20steam%20boiler" title="industrial steam boiler">industrial steam boiler</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20qualification" title=" model qualification"> model qualification</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20circulation" title=" natural circulation"> natural circulation</a>, <a href="https://publications.waset.org/abstracts/search?q=relap5%2Fmod3.2" title=" relap5/mod3.2"> relap5/mod3.2</a>, <a href="https://publications.waset.org/abstracts/search?q=steady%20state%20simulation" title=" steady state simulation"> steady state simulation</a> </p> <a href="https://publications.waset.org/abstracts/51311/steady-state-modeling-and-simulation-of-an-industrial-steam-boiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51311.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">271</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">646</span> Design and Optimization of Sustainable Buildings by Combined Cooling, Heating and Power System (CCHP) Based on Exergy Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Karimi">Saeed Karimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Behbahaninia"> Ali Behbahaninia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the design and optimization of combined cooling, heating, and power system (CCHP) for a sustainable building are dealt with. Sustainable buildings are environmentally responsible and help us to save energy also reducing waste, pollution and environmental degradation. CCHP systems are widely used to save energy sources. In these systems, electricity, cooling, and heating are generating using just one primary energy source. The selection of the size of components based on the maximum demand of users will lead to an increase in the total cost of energy and equipment for the building complex. For this purpose, a system was designed in which the prime mover (gas turbine), heat recovery boiler, and absorption chiller are lower than the needed maximum. The difference in months with peak consumption is supplied with the help of electrical absorption chiller and auxiliary boiler (and the national electricity network). In this study, the optimum capacities of each of the equipment are determined based on Thermo economic method, in a way that the annual capital cost and energy consumption will be the lowest. The design was done for a gas turbine prime mover, and finally, the optimum designs were investigated using exergy analysis and were compared with a traditional energy supply system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20building" title="sustainable building">sustainable building</a>, <a href="https://publications.waset.org/abstracts/search?q=CCHP" title=" CCHP"> CCHP</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20optimization" title=" energy optimization"> energy optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title=" gas turbine"> gas turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy" title=" exergy"> exergy</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo-economic" title=" thermo-economic"> thermo-economic</a> </p> <a href="https://publications.waset.org/abstracts/155971/design-and-optimization-of-sustainable-buildings-by-combined-cooling-heating-and-power-system-cchp-based-on-exergy-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155971.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">93</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">645</span> Dynamic Analysis of Turbine Foundation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mogens%20Saberi">Mogens Saberi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents different design approaches for the design of turbine foundations.

The uniformity of air flow in the wind-box of is very important for highly efficient operation of the CFB boiler. Non-uniform air flow distribution within the wind-box can reduce the boiler's thermal efficiency, leading to higher energy consumptions. An effective measure to solve this problem is to install an air flow distributing device in the wind-box. In order to validate the effectiveness of the air flow distributing device, visual and velocity distribution uniformity experiments have been carried out under five different test conditions by using a 1:64 scale model of a 220t/hr CFB boiler. It has been shown that the z component of flow velocity remains almost the same at control cross-sections of the wind-box, with a maximum variation of less than 10%. Moreover, the same methodology has been carried out to a full-scale 220t/hr CFB boiler. The hot test results depict that the thermal efficiency of the boiler has increased from 85.71% to 88.34% when tested with an air flow distributing device in place, which is equivalent to a saving of 5,000 tons of coal per year. The economic benefits of this energy-saving technology have been shown to be very significant, which clearly demonstrates that the technology is worth applying and popularizing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circulating%20fluidized%20bed" title="circulating fluidized bed">circulating fluidized bed</a>, <a href="https://publications.waset.org/abstracts/search?q=CFB" title=" CFB"> CFB</a>, <a href="https://publications.waset.org/abstracts/search?q=wind-box" title=" wind-box"> wind-box</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20flow%20distributing%20device" title=" air flow distributing device"> air flow distributing device</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20experiment" title=" visual experiment"> visual experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20distribution%20uniformity%20experiment" title=" velocity distribution uniformity experiment"> velocity distribution uniformity experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20test" title=" hot test"> hot test</a> </p> <a href="https://publications.waset.org/abstracts/100840/numerical-and-experimental-studies-on-the-characteristic-of-the-air-distribution-in-the-wind-box-of-a-circulating-fluidized-bed-boiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100840.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">176</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">642</span> Review of Modern Gas turbine Blade Cooling Technologies used in Aircraft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arun%20Prasath%20Subramanian">Arun Prasath Subramanian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The turbine Inlet Temperature is an important parameter which determines the efficiency of a gas turbine engine.

The mathematical approach to the problem is based on the use of heat transfer by convection and conduction equations. These equations have been chosen because of their extensive use in a wide range of application. A software and developed for solving the equations governing these phenomena and the estimation of the thermal characteristics of boiler through the study of the thermal characteristics of the heat exchanger by both LMTD and NUT methods. Subsequently, an analysis of the thermal performance of the steam boiler by studying the influence of different operating parameters on heat flux densities, temperatures, exchanged power and performance was carried out. The study showed that the behavior of the boiler is largely influenced. In the first regime (P = 3.5 bar), the boiler efficiency has improved significantly from 93.03 to 99.43 at the rate of 6.47% and 4.5%. For maximum speed, the change is less important, it is of the order of 1.06%. The results obtained in this study of great interest to industrial utilities equipped with smoke tube boilers for the preheating air temperature intervene to calculate the actual temperature of the gas so the heat exchanged will be increased and minimize temperature smoke discharge. On the other hand, this work could be used as a model of computation in the design process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title="numerical simulation">numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20tube" title=" fire tube"> fire tube</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger" title=" heat exchanger"> heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=convection%20and%20conduction" title=" convection and conduction"> convection and conduction</a> </p> <a href="https://publications.waset.org/abstracts/38371/simulation-of-improving-the-efficiency-of-a-fire-tube-steam-boiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38371.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">218</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">640</span> Hot Corrosion Susceptibility of Uncoated Boiler Tubes during High Vanadium Containing Fuel Oil Operation in Boiler Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicole%20Laws">Nicole Laws</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20L.%20Roberts"> William L.

In a super- or sub-critical steam cycle, the skin temperature of boiler tube metal can reach close to 600-1000°C depending on the location of the tubes. At high temperatures, corrosion by the sodium-vanadium-oxygen-sulfur eutectic can become a significant risk. The experimental work utilized a state-of-the-art high-temperature, high-pressure burner rig at KAUST, King Abdullah University of Science and Technology. To establish corrosion rates of different boiler tubes and materials, SA 213 T12, SA 213 T22, SA 213 T91, and Inconel 600, were used under various corrosive media, including vanadium to sulfur levels and vanadium to sodium ratios. The results obtained from the experiments establish a corrosion rate map for the materials involved and layout an empirical framework to rank the life of boiler tube materials under different operating conditions. Safe windows of operation are proposed for burning liquid fuels under varying vanadium, sodium, and sulfur levels before corrosion rates become a matter of significance under high-temperature conditions <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boiler%20tube%20life" title="boiler tube life">boiler tube life</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20corrosion" title=" hot corrosion"> hot corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=steam%20boilers" title=" steam boilers"> steam boilers</a>, <a href="https://publications.waset.org/abstracts/search?q=vanadium%20in%20fuel%20oil" title=" vanadium in fuel oil"> vanadium in fuel oil</a> </p> <a href="https://publications.waset.org/abstracts/137446/hot-corrosion-susceptibility-of-uncoated-boiler-tubes-during-high-vanadium-containing-fuel-oil-operation-in-boiler-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137446.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">233</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">639</span> Power Generation from Sewage by a Micro-Hydraulic Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomomi%20Uchiyama">Tomomi Uchiyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomoko%20Okayama"> Tomoko Okayama</a>, <a href="https://publications.waset.org/abstracts/search?q=Yukio%20Ide"> Yukio Ide</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is concerned with the development of a micro-hydraulic turbine for power generation installed in sewer pipes.

The performance of the bare and coated specimens was assessed via metal thickness loss corresponding to the corrosion scale formation and the depth of internal corrosion attack. 75Cr3C2-25NiCr coating deposited on T91 steel imparted better hot corrosion resistance than the uncoated steel. Inferior resistance of bare T91 steel is attributed to the formation of pores and loosely bounded oxide scale rich in Fe2O3. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=75Cr3C2-25NiCr" title="75Cr3C2-25NiCr">75Cr3C2-25NiCr</a>, <a href="https://publications.waset.org/abstracts/search?q=HVOF%20process" title=" HVOF process"> HVOF process</a>, <a href="https://publications.waset.org/abstracts/search?q=boiler%20steel" title=" boiler steel"> boiler steel</a>, <a href="https://publications.waset.org/abstracts/search?q=coal%20fired%20boilers" title=" coal fired boilers "> coal fired boilers </a> </p> <a href="https://publications.waset.org/abstracts/9512/high-temperature-behavior-of-a-75cr3c2-25nicr-coated-t91-boiler-steel-in-an-actual-industrial-environment-of-a-coal-fired-boiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9512.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">608</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">632</span> A Comprehensive CFD Model for Sugar-Cane Bagasse Heterogeneous Combustion in a Grate Boiler System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Jos%C3%A9%20de%20Oliveira%20Ferreira">Daniel José de Oliveira Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Harold%20Sosa-Arnao"> Juan Harold Sosa-Arnao</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20C%C3%A1ssio%20Moreira"> Bruno Cássio Moreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Paes%20Rangel"> Leonardo Paes Rangel</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%20Won%20Park"> Song Won Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The comprehensive CFD models have been used to represent and study the heterogeneous combustion of biomass. In the present work, the operation of a global flue gas circuit in the sugar-cane bagasse combustion, from wind boxes below primary air grate supply, passing by bagasse insertion in swirl burners and boiler furnace, to boiler bank outlet is simulated. It uses five different meshes representing each part of this system located in sequence: wind boxes and grate, boiler furnace, swirl burners, super heaters and boiler bank. The model considers turbulence using standard k-ε, combustion using EDM, radiation heat transfer using DTM with 16 ray directions and bagasse particle tracking represented by Schiller-Naumann model. The results showed good agreement with expected behavior found in literature and equipment design. The more detailed results view in separated parts of flue gas system allows to observe some flow behaviors that cannot be represented by usual simplifications like bagasse supply under homogeneous axial and rotational vectors and others that can be represented using new considerations like the representation of 26 thousand grate orifices by 144 rectangular inlets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comprehensive%20CFD%20model" title="comprehensive CFD model">comprehensive CFD model</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar-cane%20bagasse%20combustion" title=" sugar-cane bagasse combustion"> sugar-cane bagasse combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar-cane%20bagasse%20grate%20boiler" title=" sugar-cane bagasse grate boiler"> sugar-cane bagasse grate boiler</a>, <a href="https://publications.waset.org/abstracts/search?q=axial" title=" axial"> axial</a> </p> <a href="https://publications.waset.org/abstracts/22864/a-comprehensive-cfd-model-for-sugar-cane-bagasse-heterogeneous-combustion-in-a-grate-boiler-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22864.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">472</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">631</span> Effect of Thickness and Solidity on the Performance of Straight Type Vertical Axis Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianyang%20Zhu">Jianyang Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Jiang"> Lin Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tixian%20Tian"> Tixian Tian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inspired by the increasing interesting on the wind power associated with production of clear electric power, a numerical experiment is applied to investigate the aerodynamic performance of straight type vertical axis wind turbine with different thickness and solidity, where the incompressible Navier-Stokes (N-S) equations coupled with dynamic mesh technique is solved. By analyzing the flow field, as well as energy coefficient of different thickness and solidity turbine, it is found that the thickness and solidity can significantly influence the performance of vertical axis wind turbine. For the turbine under low tip speed, the mean energy coefficient increase with the increasing of thickness and solidity, which may improve the self starting performance of the turbine. However for the turbine under high tip speed, the appropriate thickness and smaller solidity turbine possesses better performance. In addition, delay stall and no interaction of the blade and previous separated vortex are observed around appropriate thickness and solidity turbine, therefore lead better performance characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vertical%20axis%20wind%20turbine" title="vertical axis wind turbine">vertical axis wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=N-S%20equations" title=" N-S equations"> N-S equations</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20mesh%20technique" title=" dynamic mesh technique"> dynamic mesh technique</a>, <a href="https://publications.waset.org/abstracts/search?q=thickness" title=" thickness"> thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=solidity" title=" solidity"> solidity</a> </p> <a href="https://publications.waset.org/abstracts/54216/effect-of-thickness-and-solidity-on-the-performance-of-straight-type-vertical-axis-wind-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54216.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">265</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">630</span> Optimizing Design Parameters for Efficient Saturated Steam Production in Fire Tube Boilers: A Cost-Effective Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yoftahe%20Nigussie%20Worku">Yoftahe Nigussie Worku</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research focuses on advancing fire tube boiler technology by systematically optimizing design parameters to achieve efficient saturated steam production.

The aim of the use of 3D blade is to prevent flow separation on the suction surface near the tip. The chord length is constant with radius and the blade profile changes gradually from mean radius to tip. The proposed blade profiles in the study are NACA0015 from hub to mean radius and NACA0025 at the tip. The performances of Wells turbine with 3D blades has been compared with those of the original Wells turbine, i.e. the turbine with 2-dimensional (2D) blades. As a result, it was concluded that although the peak efficiency of Wells turbine can be improved by the use of the proposed 3D blade, its blade does not overcome the weakness of stalling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluid%20machinery" title="fluid machinery">fluid machinery</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean%20engineering" title=" ocean engineering"> ocean engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=stall" title=" stall"> stall</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20energy%20conversion" title=" wave energy conversion"> wave energy conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=wells%20turbine" title=" wells turbine"> wells turbine</a> </p> <a href="https://publications.waset.org/abstracts/17316/effect-of-blade-shape-on-the-performance-of-wells-turbine-for-wave-energy-conversion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17316.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">305</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">628</span> Thermodynamic Analysis of GT Cycle with Naphtha or Natural Gas as the Fuel: A Thermodynamic Comparison</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Arpit">S.

In this sense, tests have been developed to obtain real data of parameters inherent to the work cycle, to be used later as parameters of comparison and performance analysis. In the first instance, the study consisted in testing the gas turbine with a mixture composition of 50% Biodiesel and 50% Diesel. The parameters arising from the measurements made were compared with the parameters of the gas turbine with a composition of 100% Diesel. In the second instance, the measured parameters were used to calculate the power generated and the thermal efficiency of the Kingtech K-100 turbine.

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.

The proposed approach uses a neural network that can adapt to turbines and their operating points. An algorithm monitors instantaneous wind and turbine states, predicts a wind speed that would push the turbine to a pre-defined envelope limit and, when necessary, realizes an avoidance action. Simulations are realized using the MS Bladed Wind Turbine Simulation Model for the NREL 5 MW wind turbine equipped with baseline controllers. In all simulations, through the proposed algorithm, it is observed that the turbine operates safely within the allowable limit throughout the below and above rated regions. Two example cases, adaptations to turbine operating points for the below and above rated regions and protections are investigated in simulations to show the capability of the proposed envelope protection system (EPS) algorithm, which reduces excessive wind turbine loads and expectedly increases the turbine service life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20envelope%20protection%20control" title="adaptive envelope protection control">adaptive envelope protection control</a>, <a href="https://publications.waset.org/abstracts/search?q=limit%20detection%20and%20avoidance" title=" limit detection and avoidance"> limit detection and avoidance</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=ultimate%20load%20reduction" title=" ultimate load reduction"> ultimate load reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine%20power%20control" title=" wind turbine power control"> wind turbine power control</a> </p> <a href="https://publications.waset.org/abstracts/121488/adaptive-envelope-protection-control-for-the-below-and-above-rated-regions-of-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121488.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">136</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">623</span> Aerodynamic Bicycle Torque Augmentation with a Wells Turbine in Wheels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsuyoshi%20Yamazaki">Tsuyoshi Yamazaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Etsuo%20Morishita"> Etsuo Morishita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cyclists often run through a crosswind and sometimes we experience the adverse pressure.

We incorporate the turbine to the wheel of a bike. A commercial device integrates strain gauges in the crank of a bike and transmitted force and torque applied to the pedal of the bike as an e-mail to the driver’s mobile phone. We can analyze the unsteady data in a spreadsheet sent from the crank sensor. We run the bike with the crank sensor on the rollers at the exit of a low-speed wind tunnel and analyze the effect of the crosswind to the wheel with a Wells turbine. We also test the aerodynamic characteristics of the turbine separately. Although power gain depends on the flow direction, several Watts increase might be possible by the Wells turbine incorporated to a bike wheel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=Wells%20turbine" title=" Wells turbine"> Wells turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=bicycle" title=" bicycle"> bicycle</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20engineering" title=" wind engineering"> wind engineering</a> </p> <a href="https://publications.waset.org/abstracts/84277/aerodynamic-bicycle-torque-augmentation-with-a-wells-turbine-in-wheels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84277.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">180</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">622</span> A Design Method for Wind Turbine Blade to Have Uniform Strength and Optimum Power Generation Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pengfei%20Liu">Pengfei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yiyi%20Xu"> Yiyi Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There have been substantial incidents of wind turbine blade fractures and failures due to the lack of systematic blade strength design method incorporated with the aerodynamic forces and power generation efficiency. This research was to develop a methodology and procedure for the wind turbine rotor blade strength taking into account the strength, integration, and aerodynamic performance in terms of power generation efficiency. The wind turbine blade designed using this method and procedure will have a uniform strength across the span to save unnecessary thickness in many blade radial locations and yet to maintain the optimum power generation performance. A turbine rotor code, taking into account both aerodynamic and structural properties, was developed. An existing wind turbine blade was used as an example. For a condition of extreme wind speed of 100 km per hour, the design reduced about 19% of material usage while maintaining the optimum power regeneration efficiency. <p
