Study on the Fire Hazard of Shenhua Pulverized Coal

In this paper, the fire risk parameters of three kinds of pulverized coal in Shenhua coal direct liquefaction project were tested, and from the two aspects of coal explosion sensitivity and explosive intensity, the impact of the sample fire hazard by the moisture content and the iron catalyst content in pulverized coal were analyzed and compared. The results show that: (1) the higher the moisture content in the pulverized coal, the smaller the explosive index of coal powder; (2) the presence of the appropriate amount of iron catalyst in the catalyst pulverized coal leads to increased explosive strength of coal.
