摘要：
This article examines the composition of injected fuel for large-volume blast furnaces. A rise in the combustion efficiency of pulverized coal within a combustion zone and the degree of indirect reduction was observed as the consumption of pulverized coal decreased while that of natural gas increased. Consequently, the total fuel consumption at a constant level of coke consumption was reduced.
