A reheat steam temperature adjustment test was conducted on the two subcritical, intermediate reheat and natural circulation boilers in the power plant. By analyzing the test data, reasons of the low reheat steam temperature have been discovered. What's more, three schemes about capacity-increasing transformation for reheaters have been proposed and compared, after which the most reasonable one is selected. What is studied in the paper provides helpful experiences in solving similar problems for boilers of the same type.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"544 1","pages":"698-702"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77145577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a hybrid solar-wind powered charging station was designed to provide electricity for the electric vehicles according to the wind and solar condition of the coastal areas in Tangshan. The key components including wind turbines, PV modules, batteries, an inverter and other controllers were considered. In order to determine the capacities of the components, LPSP was used as a control condition to obtain the configurations achieving the demand energy and the costs of every configuration as the other control condition were calculated to optimize the system. At last, the minimum-cost configuration achieving the demand energy was found as the result of the designation.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"1 1","pages":"977-981"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77142003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigated gaseous fuels were methane diluted with nitrogen, simulating LCVGs with different heat values by regulating quantity of nitrogen. The flame shape and thermal field are consistent with experimental results. It consists of two segments of different feature, the lengths of which dependent on inlet velocity. Comparative study of flow fields at cold and thermal states were carried out with an aim to gain further understanding of the flow/flame interaction in the tubular burner. Heat release from combustion diverts the main pressure gradient to axial direction, thereby tangential velocity drop tends to close with axis of swirling, and axial velocity distribution changes to be trapezoid-shaped. Changing in low heat values influences the burning positively, while the flow does not exert an apparent effect.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"1 1","pages":"770-773"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76172351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can store or transfer a large amount of thermal energy by using the latent heat capacity of the paraffin during the phase transition as well as the sensible heat capacity of water. In this study, hexadecane O/W microemulsions were emulsified by an ionic surfactant SDS and a co-surfactant butanol. The phase behavior, effective stability, droplet size and thermophysical properties, such as latent heat and dynamic viscosity, were investigated experimentally. The results showed the prepared microemulsion with 30 wt.% hexadecane has expected high heat capacity about 93.4 J/g and low viscosity about 21 mpa·s. The average droplet size is 73 nm. The results indicate that they have potential applications in thermal energy storage and transfer.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"12 1","pages":"504-507"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82768071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
