摘要
针对干熄焦装置斜道区莫来石-碳化硅砖使用寿命短的情况,研究开发了β-碳化硅砖,其使用寿命可达6年。经理论计算,应用β-碳化硅砖后的干熄焦节能效率提高约5.5%,1座140t/h的干熄焦装置6年累计增加节约标煤约1.53万t、节水约17.2万t、节约焦粉约30.64t、减排大气污染物约25.7t。
In view of the short service life of mullite-SiC brick used in CDQ connecting duct,β-SiC brick is developed with service life up to 6 years. Theoretically,with the β-SIC brick, energy can be saved by about 5.5% ,in continuous 6-year operation for 1 x 140t/h CDQ system, energy consump- tion can be saved by about 15 300 tons in standard coal,by about 172 000 tons in water and by about 30.64 tons in coke breeze, and atmospheric pollutant can be reduced by 25.7 tons approximately.
