Abstract

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.

通过优化喷射燃料的组成，提高了新罗佩茨克钢铁公司（NLMK）高炉熔炼效率

本文研究了大容积高炉喷射燃料的成分。随着煤粉消耗量的减少和天然气消耗量的增加，观察到燃烧区内煤粉燃烧效率的提高和间接减少的程度。因此，在焦炭消耗量保持不变的情况下，总燃料消耗量减少了。
