-The main factor responsible for the decrease in coke consumption by increasing the natural gas is decrease in the direct reduction of iron (rd).
-When rd < 20% , the differential equivalent of coke replacement falls from 0.9-1.0 to 0.2-0.4 kg/m3.
-The influence of coke-oven gas is analogous when the supply ratio of the coke-oven gas and natural gas is 1: 2.
-The main factor that determined the substitution of coke pulverized coal fuel is the heat of combustion of coal-dust.
-Predominant over consumption of coke in enrichment of blast oxygen is the reduction of heat nitrogen.
