Abstract:

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 1×140t/h CDQ system,energy consumption 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.
