    Advanced Pulverized Coal Injection Technology and Blast

    In order to reduce the cost of running blast furnaces BFs, injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column. The capacity of the furnace to consume these particles by solution loss is probably one of the limitations
