Analysis and Research of Explosive Coal Explosivity in Coal-fired Power Plants

According to the explosion of pulverized coal system in a coal-fired power plant in Shandong, this paper analyzes the explosivity of the coal. According to the explosive index, the coal can be divided into the most explosive coal, the more explosive coal, explosive coal and normal coal. According to the proximate analysis and net calorific value of coal this paper fitted linear formula of explosive index by the method of least squares, and the error of coal prediction explosive index was analyzed. The formula could be used to predict explosive index of coal.
