It consists of two homocentric upright cylinders with some annularly located spouting gas nozzles between inner and outer cylinders. A three-dimensional Eulerian multiphase model, with closure law according to the kinetic theory of granular flow, was used to simulate the gas/solid flow behaviors in the spouted beds. The simulation results show that numerical simulation is a useful tool to get detailed information about the gas/solid turbulent motions in the novel spouted beds. Along the bed height, the pressure tends to decrease. Particle concentration increases with increasing of distance away from the nozzle. The particle concentration is less for a high spouting gas velocity. The gas velocities at the center axis of nozzle decrease with increasing the static bed height.","PeriodicalId":6348,"journal":{"name":"2009 International Conference on Energy and Environment Technology","volume":"18 1","pages":"218-221"},"PeriodicalIF":0.0,"publicationDate":"2009-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76366279","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 technology of auto-reclose has been widely used on the transmission lines in our country. The purpose is to make the fault line re-run after the temporary fault elimination. As most of the faults are transient in nature, the auto-reclose can greatly improve the reliability of the electricity and the stability of the power system, running side by side. The setting time of the conventional single-phase auto-reclose is determined by a fixed value, when the single-phase opens, auto-reclose recloses at the fixed-time regardless of the fault existence or not, as well as the secondary arc current. In this paper, the issue is given a reasonable solution. According to the arc eliminating time, the dynamic reclosing time is determined.","PeriodicalId":6348,"journal":{"name":"2009 International Conference on Energy and Environment Technology","volume":"34 1","pages":"279-282"},"PeriodicalIF":0.0,"publicationDate":"2009-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82438167","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}

Therefore, it is important to study its toxic effects on plants, animals, and humans. In the present study, the genotoxicity of coke plant wastewater was studied using the Vicia faba root-tip cytogenetic bioassay. The results show that coke plant wastewater decreased the mitotic index (MI) and caused significant increases of micronucleus (MCN) frequencies and anaphase aberration (AA) frequencies in a concentration-dependent manner (Chemical oxygen demand (CODcr) as a measure of coke plant wastewater concentration) and a time-dependent manner. The results also show that components of coke plant wastewater may be genotoxic in plant cells and imply that long exposure to coke plant wastewater at low concentrations may pose a potential genotoxic risk to organisms. The results of the present study suggest that the V. faba cytogenetic bioassay is efficient, simple in genotoxicity studies of coke plant wastewater, and that there is a correlation between the genotoxicity and CODcr of coke plant wastewater.","PeriodicalId":6348,"journal":{"name":"2009 International Conference on Energy and Environment Technology","volume":"75 1","pages":"593-596"},"PeriodicalIF":0.0,"publicationDate":"2009-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80912574","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 technical requirements of mine thermal environment are getting higher and higher. It can not effectively solve the problem of mining high-temperature by using the general cooling ways. With general ways, the system needs to consume a large amount of energy. At the same time by using of Freon refrigerant, it will emit a lot of greenhouse gases. All of these are not in conformity with the relationship between the requirements of sustainable development and the vital interests of human development. In this paper, the program of vortex tube cooling in deep well has been advanced. Vortex tube has advantages of simple structure, no moving parts, working stability and has a wide-range working scope. It has been applied in some respects. It has a large cooling speed and does not use the Freon refrigerant. This paper conducted a feasibility analysis of vortex tube cooling, proved that vortex tube cooling in deep well meet the cooling needs, has a better economic efficiency at the same time has highly energy and environmental benefits. Vortex tube cooling in deep well realizes the energy-saving and emission reduction in the true sense.","PeriodicalId":6348,"journal":{"name":"2009 International Conference on Energy and Environment Technology","volume":"107 1","pages":"885-887"},"PeriodicalIF":0.0,"publicationDate":"2009-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80986654","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}

It was be found that temperature has important influence on both radiative and convective heat transfer. The CO2 density is very important in enhancing the radiative heat transfer.
