Total dioxin’s and Cl5 benzene’s concentrations in the exhaust gas have a good correlation with the number of the fly C* remaining in the exhaust gas, and their concentrations increase as the number of the fly C* rises. Total dioxin’s and Cl5 benzene’s concentrations after the centrifugation and recombustion with the present cyclone reduce to 10% and 20% of their initial concentrations in the exhaust gas from combustion furnace, respectively, in proportion to the decrease in the fly C*. On the other hand, in the case of low dioxin’s and benzene’s concentrations in the exhaust gas under the complete combustion conditions their reduction ratios become worse. The reason why their reduction ratios decrease is considered a decrease in the partial separation efficiency for fine particles in the present cyclone, which is attributed to the increase in the relative ratio of the fly C* with the sizes smaller than 2μm under the complete combustion conditions. The predictive equation of the partial separation efficiency at high temperatures obtained for the present cyclone of a small size indicates that the reduction ratios of dioxins and benzenes are much improved by using the cyclone of larger sizes and increasing in the inlet velocity of the exhaust gas to the cyclone. The present centrifugation and recombustion method of the exhaust gas at high temperatures is expected to be useful for the actual incineration plants.","PeriodicalId":113412,"journal":{"name":"Journal of High Temperature Society","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131057185","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}

Cobalt-based alloy coatings are fabricated by using three thermal spray processes: atmospheric plasma spray, low-pressure plasma spray and high velocity oxygen fuel flame spray. The ultrasonic vibration type cavitation erosion testing apparatus were employed for the cavitation erosion rate measurement. The cavitation erosion performances determined by the specific volume loss rate of low-pressure plasma-sprayed cobalt-based alloy and HVOF sprayed cobalt-based alloy coatings were improved five times and twice compared with that of aluminum bronze castings, respectively. The anti-cavitation erosion performance of atmospheric plasma sprayed cobalt-based alloy coating did not reach the level of aluminum bronze castings.","PeriodicalId":113412,"journal":{"name":"Journal of High Temperature Society","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126996935","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}

But, we have a lot of problem on wood biomass utilities in social situations and geography conditions. Especially, to move of biomass from mountain area to user side transportation coast rises. Therefore, we have to improve for thermal energy characteristics in biomass based on moving. This technology is new carbonized technology for improvement of biomass thermal energy characteristics. This technology controls heated temperature and pressed force by hot-press method. Fundamental properties of biomass show thermal decomposition and ultimate analysis. In these results, we suggest to occur a half carbonized phenomena for improvement of thermal energy. Half carbonized phenomena begin approximately 540K in sawdust and 580K in cellulose. And, total calorifi c value suddenly increases in these heated temperatures. Sawdust could suggest occurring lower 40K to compare cellulose.","PeriodicalId":113412,"journal":{"name":"Journal of High Temperature Society","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125430679","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}
