Abstract

Om: The function of the actions of coke in the blast furnace is to offer a reaction space and gas passage. The damage to coke is an important problem for blast furnaces with large coal rates. This worsens the effect of coke as a framework for the burden. The decrease in the proportion of coke in the burden is the main reason for this. The combustion rate of injected coal is an important parameter. Increasing it is a significant target. However, this should be further discussed in the context of large coal rates. The non-combusted carbon in coal char plays an important role in protecting the coke. This effect and the suitable combustion rate of coal will be mainly discussed in this paper.
