Green and Low-carbon Design Features of the Revamped Hot Stove of WISCO No.6 BF
It is introduced the green and low-carbon design features of the revamped hot stove of WISCO No.6 BF.In its op-eration during the first generation campaign,the furnace suffered the problems,such as low blast temperature,high gas con-sumption per ton of hot metal,and higher concentration of waste gas in the emitted gas than that required by the ultra-low e-mission policy.So,in the revamping of the hot stove system,transformation for increasing hot blast temperature and reducing gas consumption is made in the design,and an off-gas desulphurization system is installed.The transformation design com-prehensively enhances the technological equipment capacity of the stove system,and promotes the equipment modernization and green development.After commissioning of the revamped stove,the hot blast temperature reaches 1220℃ while fueled by BFG only,and the gas consumption per ton of hot metal is greatly reduced to less than 450 m3/t.
