Abstract: Abstract:According to the characteristics of double inlet and double outlet coal mill, combining with pulverized coal deflagration theory, the principle of explosion of pulverized coal, which probably occurs in a double inlet and double outlet coal mill when pulverizing lignite, and the factors influencing on the explosion accident were analyzed. The concrete measures for preventing explosion of coal pulverizing system were put forward. The probability of explosion accident was decreased effectively, and the safety of the operation was improved.
