There are huge efforts and study has been done so far on phase transformations, due to so many steel grades available commercially the phase development in steel has different consequences. In the present work an effort has been made to study the effect of heating rate on microstructural features of cold heading quality steel. The SEM, optical microscopy, and heat treatment techniques have been applied to observe the microstructural features in the experimental steel. It was observed that heating rate has the strong influence on phase transformation of CHQ steel under investigation. Heating rate increases the austenite formation kinetics with respect to holding time, and this austenite has been transformed to martensite upon cooling. Heating rate also plays a vital role on nucleation sites of austenite formation in the experimental steel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CHQ%20steel" title="CHQ steel">CHQ steel</a>, <a href="https://publications.waset.org/abstracts/search?q=austenite%20formation" title=" austenite formation"> austenite formation</a>, <a href="https://publications.waset.org/abstracts/search?q=heating%20rate" title=" heating rate"> heating rate</a>, <a href="https://publications.waset.org/abstracts/search?q=nucleation" title=" nucleation"> nucleation</a> </p> <a href="https://publications.waset.org/abstracts/66565/effect-of-heating-rate-on-microstructural-developments-in-cold-heading-quality-steel-used-for-automotive-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66565.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">410</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">8879</span> Fabrication of Cesium Iodide Columns by Rapid Heating Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chien-Wan%20Hun">Chien-Wan Hun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shao-Fu%20Chang"> Shao-Fu Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Chon%20Chen"> Chien-Chon Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ker-Jer%20Huang"> Ker-Jer Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents how to use a high-efficiency process for producing cesium iodide (CsI) crystal columns by rapid heating method. In the past, the heating rate of the resistance wire heating furnace was relatively slow and excessive iodine and CsI vapors were therefore generated during heating. Because much iodine and CsI vapors are produced during heating process, the composition of CsI crystal columns is not correct. In order to enhance the heating rate, making CsI material in the heating process can quickly reach the melting point temperature. This study replaced the traditional type of external resistance heating furnace with halogen-type quartz heater, and then, CsI material can quickly reach the melting point. Eventually, CsI melt can solidify in the anodic aluminum template forming CsI crystal columns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cesium%20iodide" title="cesium iodide">cesium iodide</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20efficiency" title=" high efficiency"> high efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=vapor" title=" vapor"> vapor</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20heating" title=" rapid heating"> rapid heating</a>, <a href="https://publications.waset.org/abstracts/search?q=crystal%20column" title=" crystal column"> crystal column</a> </p> <a href="https://publications.waset.org/abstracts/69695/fabrication-of-cesium-iodide-columns-by-rapid-heating-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69695.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">373</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">8878</span> Slow Pyrolysis of Bio-Wastes: Environmental, Exergetic, and Energetic (3E) Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Zalazar-Garcia">Daniela Zalazar-Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20Torres"> Erick Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=German%20Mazza"> German Mazza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Slow pyrolysis of a pellet of pistachio waste was studied using a lab-scale stainless-steel reactor.

Experimental results showed that biochar and gas yields decreased with an increase in the heating rate (43 to 36 % and 28 to 24 %, respectively), while the bio-oil yield increased (29 to 40 %). Finally, from the 3-E analysis and the experimental results, it can be suggested that an increase in the heating rate resulted in a higher pyrolysis exergetic efficiency (70 %) due to an increase of the bio-oil yield with high-energy content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3E%20assessment" title="3E assessment">3E assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-waste%20pellet" title=" bio-waste pellet"> bio-waste pellet</a>, <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=slow%20pyrolysis" title=" slow pyrolysis"> slow pyrolysis</a> </p> <a href="https://publications.waset.org/abstracts/139075/slow-pyrolysis-of-bio-wastes-environmental-exergetic-and-energetic-3e-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139075.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">221</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">8877</span> CFD Analysis of Solar Floor Radiant Heating System with ‎PCM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Nazififard">Mohammad Nazififard</a>, <a href="https://publications.waset.org/abstracts/search?q=Reihane%20Faghihi"> Reihane Faghihi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is aimed at understanding convective heat transfer of enclosed phase change material (PCM) in the solar and low-temperature hot water radiant floor heating geometry.

The governing equations are numerically solved. The PCM thermal storage time is considered in relation to the floor surface temperature under different hot water temperatures.

In this work, the heat release rates of pine, fir wood and mahogany pellets at 30–70℃ were measured by TAM air isothermal calorimeter, and the kinetic analysis was performed by iso-conversion ratio and non-steady-state methods to evaluate its self-heating potential. The results show that the reaction temperature can significantly affect the heat release rate. The higher the temperature, the greater the heat release rate. The heat release rates of different kinds of wood pellets are obviously different, and the order of the heat release rates for the three pellets at 70℃ is pine > fir wood > mahogany. The kinetic analysis of the iso-conversion ratio method indicates that the distribution of activation energy for pine, fir wood and mahogany pellets under the release of 0.1–1.0 J/g specific heat are 58–102 kJ/mol, 59–108 kJ/mol and 59–112 kJ/mol, respectively. Their activation energies obtained from the non-steady-state kinetic analysis are 13.43 kJ/mol, 19.19 kJ/mol and 21.09 kJ/mol, respectively. Both kinetic analyses show that the magnitude of self-heating risk for the three pellet fuels is pine pellets > fir wood pellets > mahogany pellets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isothermal%20calorimeter" title="isothermal calorimeter">isothermal calorimeter</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=self-heating" title=" self-heating"> self-heating</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20pellets" title=" wood pellets"> wood pellets</a> </p> <a href="https://publications.waset.org/abstracts/147219/kinetic-analysis-of-wood-pellets-by-isothermal-calorimetry-for-evaluating-its-self-heating-potential" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147219.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">173</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">8875</span> Simulation Model of Induction Heating in COMSOL Multiphysics </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Djellabi">K.

The mathematical analysis of this problem in most cases is very difficult and it is reduced to simple cases. Another knowledge of induction heating systems is generated in production environments, but these trial-error procedures are long and expensive. The numerical models of induction heating problem are another approach to reduce abovementioned drawbacks. This paper deals with the simulation model of induction heating problem. The simulation model of induction heating system in COMSOL Multiphysics is created. In this work we present results of numerical simulations of induction heating process in pieces of cylindrical shapes, in an inductor with four coils.

Four different samples were prepared by polishing the surfaces of the alloy by 80, 220, 600 grit sizes of SiC abrasive papers and diamond paste. The samples were heated in air for 6 h at 833°K, and the emissivity was measured during the process from pyrometers operating at wavelengths of 3.9, 5.14 and 7.8 μm. The results indicated that the emissivity was increasing with heating time and the rate of increase was rapid during the initial stage of heating in comparison with the later stage. This appears to be because of the parabolic rate law followed by the process of oxidation. Further, it is found that the increase in emissivity with heating time was higher for rough surfaces than that for polished surfaces. Both the results were analyzed at all the three wavelengths, and qualitatively similar results were obtained for all of them. In this way emissivity of the alloy can be increased by roughening the surfaces and heating it at high temperature until the surfaces are oxidized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloy" title="aluminum alloy">aluminum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20temperature" title=" high temperature"> high temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=normal%20spectral%20emissivity" title=" normal spectral emissivity"> normal spectral emissivity</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a> </p> <a href="https://publications.waset.org/abstracts/101984/normal-spectral-emissivity-of-roughened-aluminum-alloy-al-6061-surfaces-at-high-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101984.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">227</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">8872</span> Simulation Study on Comparison of Thermal Comfort during Heating with All-Air System and Radiant Floor System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shiyun%20Liu">Shiyun Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radiant heating systems work fundamentally differently from air systems by taking advantage of both radiant and convective heat transfer to remove space heating load.

This process can also be used as a pre-treatment for other thermochemical processes. The torrefaction of spelt husks was carried out at temperatures of 200, 250, and 300oC in an inert nitrogen environment with a heating rate of 20oC.min-1 and a residence time of 15–60 min, respectively. We examined the influence of torrefaction temperatures and residence time. The results indicated that increasing the torrefaction temperature increased the higher heating values (HHV) and improved grindability. Torrefied spelt husks at 300oC for 15 minutes exhibited the highest increase in HHV at 30.88 MJ kg-1, compared to non-torrefied spelt husks at 17.56 MJ kg-1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grindability" title="grindability">grindability</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20heating%20value" title=" higher heating value"> higher heating value</a>, <a href="https://publications.waset.org/abstracts/search?q=residence%20time" title=" residence time"> residence time</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=torrefaction" title=" torrefaction"> torrefaction</a> </p> <a href="https://publications.waset.org/abstracts/142469/torrefaction-of-spelt-husks-to-increase-its-fuel-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142469.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">184</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">8870</span> Heating Behavior of Ni-Embedded Thermoplastic Polyurethane Adhesive Film by Induction Heating</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=DuckHwan%20Bae">DuckHwan Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=YongSung%20Kwon"> YongSung Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Young%20Shon"> Min Young Shon</a>, <a href="https://publications.waset.org/abstracts/search?q=SanTaek%20Oh"> SanTaek Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=GuNi%20Kim"> GuNi Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The heating behavior of nanometer and micrometer sized Nickel particle-imbedded thermoplastic polyurethane adhesive (TPU) under induction heating is examined in present study.

Two heating modes – auto and manual mode were applied to observe the role of electrical induction on heating. Temperature, electric current, and pulse pattern were experimented with grade iron γ-Al2O3 powders. Phase transformation of γ to α -Al2O3 serves as a direct indicator of internal temperature, independently on measured outside temperature. That pulsing in SPS is also able to induce internal heating due to its strong electromagnetic field when dopants are conductive metals (e.g., iron) is proofed during SPS. Density and microstructure were investigated to explain the mechanism of induction heating. In addition, the role of electric pulsing and strong electromagnetic field on internal heating (induction heating) were compared and discussed. Internal heating by iron doping within electrically nonconductive samples is able to decrease sintering temperature and save energy, furthermore it is one explanation for unique features of this material fabrication technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spark%20plasma%20sintering" title="spark plasma sintering">spark plasma sintering</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20heating" title=" induction heating"> induction heating</a>, <a href="https://publications.waset.org/abstracts/search?q=alumina" title=" alumina"> alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/54836/impact-of-iron-doping-on-induction-heating-during-spark-plasma-sintering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54836.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">331</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">8868</span> Technical Analysis of Combined Solar Water Heating Systems for Cold Climate Regions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Lotfizadeh">Hossein Lotfizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20McDonald"> André McDonald</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Kumar"> Amit Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Renewable energy resources, which can supplement space and water heating for residential buildings, can have a noticeable impact on natural gas consumption and air pollution. This study considers a technical analysis of a combined solar water heating system with evacuated tube solar collectors for different solar coverage, ranging from 20% to 100% of the total roof area of a typical residential building located in Edmonton, Alberta, Canada. The alternative heating systems were conventional (non-condensing) and condensing tankless water heaters and condensing boilers that were coupled to solar water heating systems. The performance of the alternative heating systems was compared to a traditional heating system, consisting of a conventional boiler, applied to houses of various gross floor areas. A comparison among the annual natural gas consumption, carbon dioxide (CO<sub>2</sub>) mitigation, and emissions for the various house sizes indicated that the combined solar heating system can reduce the natural gas consumption and CO<sub>2</sub> emissions, and increase CO<sub>2</sub> mitigation for all the systems that were studied. The results suggest that solar water heating systems are potentially beneficial for residential heating system applications in terms of energy savings and CO<sub>2</sub> mitigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO2%20emissions" title="CO2 emissions">CO2 emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20mitigation" title=" CO2 mitigation"> CO2 mitigation</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20gas%20consumption" title=" natural gas consumption"> natural gas consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20water%20heating%20system" title=" solar water heating system"> solar water heating system</a> </p> <a href="https://publications.waset.org/abstracts/49148/technical-analysis-of-combined-solar-water-heating-systems-for-cold-climate-regions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49148.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">324</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">8867</span> Synthesis and Characterization of CaZrTi2O7 from Tartrate Precursor Employing Microwave Heating Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20M.%20Patil">B.

In the present work the nanocrystalline CaZrTi2O7 was synthesized from Calcium Zirconyl Titanate tartrate precursor (CZTT) employing two different heating techniques such as Conventional heating (Muffle furnace) and Microwave heating (Microwave Oven). Thermal decomposition of the CZTT precursors in air yielded nanocrystalline CaZrTi2O7 powder as the end product. The products obtained by annealing the CZTT precursor using both heating method were characterized using simultaneous TG-DTA, FTIR, XRD, SEM, TEM, NTA and thermodilatometric study. The physical characteristics such as crystallinity, morphology and particle size of the product obtained by heating the CZTT precursor at the different temperatures in a Muffle furnace and Microwave oven were found to be significantly different. The microwave heating technique considerably lowered the synthesis temperature of CaZrTi2O7. The influence of microwave heating was more pronounced as compared to Muffle furnace heating. The details of the synthesis of CaZrTi2O7 from CZTT precursor are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CZTT" title="CZTT">CZTT</a>, <a href="https://publications.waset.org/abstracts/search?q=CaZrTi2O7" title=" CaZrTi2O7"> CaZrTi2O7</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave" title=" microwave"> microwave</a>, <a href="https://publications.waset.org/abstracts/search?q=SYNROC" title=" SYNROC"> SYNROC</a>, <a href="https://publications.waset.org/abstracts/search?q=zirconolite" title=" zirconolite "> zirconolite </a> </p> <a href="https://publications.waset.org/abstracts/79296/synthesis-and-characterization-of-cazrti2o7-from-tartrate-precursor-employing-microwave-heating-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79296.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">165</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">8866</span> Present an Active Solar Energy System to Supply Heating Demands of the Teaching Staff Dormitory of Islamic Azad University of Ramhormoz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Talebzadegan">M.

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">369</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">8860</span> Copper Coil Heat Exchanger Performance for Greenhouse Heating: An Experimental and Theoretical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Bakkari">Maha Bakkari</a>, <a href="https://publications.waset.org/abstracts/search?q=R.Tadili"> R.Tadili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work is a study of the performance of a solar copper coil heating system in a greenhouse microclimate. Our system is based on the circulation of a Heat transfer fluid, which is water in our case, in a closed loop under the greenhouse's roof in order to store heat all day, and then this heat will supply the greenhouse during the night. In order to evaluate our greenhouse, we made an experimental study in two identical greenhouses, where the first one is equipped with a heating system and the second (without heating) is used for control. The heating system allows the establishment of the thermal balance and determines the mass of water necessary for the process in order to ensure its functioning during the night. The results obtained showed that this solar heating system and the climatic parameters inside the experimental greenhouse were improved, and it presents a significant gain compared to a controlled greenhouse without a heating system. This research is one of the solutions that help to reduce the greenhouse effect of the planet Earth, a problem that worries the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse" title=" greenhouse"> greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a> </p> <a href="https://publications.waset.org/abstracts/167095/copper-coil-heat-exchanger-performance-for-greenhouse-heating-an-experimental-and-theoretical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167095.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">78</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">8859</span> Electromagnetic Interference Shielding Effectiveness of a Corrugated Rectangular Waveguide for a Microwave Conveyor-Belt Drier </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sang-Hyeon%20Bae">Sang-Hyeon Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Yeon%20Kim"> Sung-Yeon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Gyo%20Jeong"> Min-Gyo Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Hong%20Kim"> Ji-Hong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang-Sang%20Lee"> Wang-Sang Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional heating methods such as electric ovens or steam heating are slow and not very efficient. For continuously heating the objects, a microwave conveyor-belt drier is widely used in the industrial microwave heating systems. However, there is a problem in which electromagnetic wave leaks toward outside of the heating cavity through the insertion opening. To achieve the prevention of the leakage of microwaves and improved heating characteristics, the corrugated rectangular waveguide at the entrance and exit openings of a microwave conveyor-belt drier is proposed and its electromagnetic interference (EMI) shielding effectiveness is analyzed and verified.

This steel was developed with higher creep strength property as compared to conventional low alloy steel. However, this steel is also susceptible to materials degradation due to its sensitivity to heat treatment especially Post Weld Heat Treatment (PWHT) after weld repair process. Review of PWHT process shows that the holding temperature may different from one batch to other batch of samples depending on the material composition. This issue was reviewed by many researchers and one of the potential solutions is the development of weld repair process without PWHT. This process is possible with the use of temper bead welding technique. However, study has shown the hardness value across the weld joint with exception of PWHT is much higher compare to recommended hardness value. Based on the above findings, a study to evaluate the microstructure and hardness changes of T91 weld joint after heating at 560°C at varying duration was carried out. This study was carried out to evaluate the possibility of self-tempering process during in-service period. In this study, the T91 weld joint was heat-up in air furnace at 560°C for duration of 50 and 150 hours. The heating process was controlled with heating rate of 200°C/hours, and cooling rate about 100°C/hours. Following this process, samples were prepared for the microstructure examination and hardness evaluation. Results have shown full tempered martensite structure and acceptance hardness value was achieved after 50 hours heating. This result shows that the thin component such as T91 superheater tubes is able to self-tempering during service hour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=T91" title="T91">T91</a>, <a href="https://publications.waset.org/abstracts/search?q=weld-joint" title=" weld-joint"> weld-joint</a>, <a href="https://publications.waset.org/abstracts/search?q=tempered%20martensite" title=" tempered martensite"> tempered martensite</a>, <a href="https://publications.waset.org/abstracts/search?q=self-tempering" title=" self-tempering"> self-tempering</a> </p> <a href="https://publications.waset.org/abstracts/34840/microstructure-and-hardness-changes-on-t91-weld-joint-after-heating-at-560c" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34840.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">379</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">8856</span> Performance Evaluation of Thermosiphon Based Solar Water Heater in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dnyandip%20K.%20Bhamare">Dnyandip K.

Mango pulp was processed by using ohmic heating under the studied suitable conditions. Physical, chemical and microbiological properties of mango pulp were studied. The results showed that processing of mango pulp by using either ohmic heating or conventional method caused a decrease in the contents of TSS, total carbohydrates, total acidity, total sugars (reducing and non-reducing sugar) and an increase in phenol content, ascorbic acid and carotenoids compared to the conventional process. The increase in electric conductivity of mango pulp during ohmic heating was due to the addition of some electrolytes (salts) to increase the ions and enhance the process. The results also indicate that mango pulp processed by ohmic heating contained more phenols, carbohydrates and vitamin C and less HMF compared to that produced by conventional one. Total pectin and its fractions had slightly reduced by ohmic heating compared to conventional method. Enzymatic activities showed a reduction in poly phenoloxidase (PPO) and polygalacturonase (PG) activity in mango pulp processed by conventional method. However, ohmic heating completely inhibited PPO and PG activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ohmic%20heating" title="ohmic heating">ohmic heating</a>, <a href="https://publications.waset.org/abstracts/search?q=mango%20pulp" title=" mango pulp"> mango pulp</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic" title=" phenolic"> phenolic</a>, <a href="https://publications.waset.org/abstracts/search?q=sarotenoids" title=" sarotenoids "> sarotenoids </a> </p> <a href="https://publications.waset.org/abstracts/7967/production-and-evaluation-of-mango-pulp-by-using-ohmic-heating-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7967.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">456</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">8854</span> A Platform to Analyze Controllers for Solar Hot Water Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aziz%20Ahmad">Aziz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillermo%20Ramirez-Prado"> Guillermo Ramirez-Prado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Governments around the world encourage the use of solar water heating in residential houses due to the low maintenance requirements and efficiency of the solar collector water heating systems.

Drying of biomass particles bed is described by mass diffusion equation and local moisture-vapour-equilibrium relations. In gasifiers, volatilization rate during pyrolysis of biomass is modeled by using apparent kinetic rate expression, while product compositions at slow heating rates is modeled using empirical fitted mass ratios (i.e., CO/CO<sub>2</sub>, ME/CO<sub>2</sub>, H<sub>2</sub>O/CO<sub>2</sub>) in terms of pyrolysis temperature. The drying module is validated fairly with available chemical kinetics scheme and found that the testing zone in gasifier bed constituted of relatively smaller particles having high airflow with high isothermal temperature expedite the drying process. Further, volatile releases more quickly within the shorter zone height at high temperatures (isothermal).

Therefore, main components of the building heating systems play an essential role in terms of energy consumption. In this context, efficient energy and exergy utilization in HVAC-R systems has been very essential, especially in developing energy policies towards increasing efficiencies. The main objective of the present study is to assess the performance of a family house with a volume of 326.7 m3 and a net floor area of 121 m2, located in the city of Izmir, Turkey in terms of energetic, exergetic and sustainability aspects. The indoor and exterior air temperatures are taken as 20°C and 1°C, respectively. In the analysis and assessment, various metrics (indices or indicators) such as exergetic efficiency, exergy flexibility ratio and sustainability index are utilized. Two heating options (Case 1: condensing boiler and Case 2: air heat pump) are considered for comparison purposes. The total heat loss rate of the family house is determined to be 3770.72 W. The overall energy efficiencies of the studied cases are calculated to be 49.4% for Case 1 and 54.7% for Case 2. The overall exergy efficiencies, the flexibility factor and the sustainability index of Cases 1 and 2 are computed to be around 3.3%, 0.17 and 1.034, respectively. <p
