Abstract

Pulverized coal injection of blast furnace is the important means of lowering ironmaking cost. It is a focus problem to improve the pulverized coal injection rate of blast furnace. However, improve the pulverized coal combustion rate has became a bottleneck of coal injection rate because of the contradiction between unburned pulverized coal and BF smooth operation. Basis of traditional technique, a new method by preheating pulverized coal to improve the pulverized coal combustion rate has been studied. Research shows that preheating pulverized coal can promote the pulverized coal combustion ratio, and reduce the heat loss of pulverized coal in BF through preheating pulverized coal.
