Abstract:

To meet the requirement of reducing ash content in coke by Masteel,13 kinds of coal blending schemes are determined based on each individual kind of coal from Huaibei coal mines,which have been washed and selected into different ash contents by coal dressing method.The blended coal quality and the coke quality produced from 40kg test oven are analyzed. The result shows that the blended coal ash content,ash catalytic index and caking property vary with the ash content of Huaibei coal,in which the Huaibei lean coal ash content decreases,and the coke quality increases accordingly.
