[0002] Pulverized coal refers to coal with a particle size of less than 6mm. Pulverized coal particle size is an important physical parameter of pulverized coal combustion. The particle size significantly affects the temperature of its combustion flame, the degree of burnout and the emission of NO2. With the improvement of comprehensive mining level and the increase in the proportion of lower-group coal mining, the pulverized coal content continues to increase. In addition, due to long-distance transportation, a considerable portion of the raw coal reaching the hands of users is pulverized coal, resulting in the increasing contradiction between the shortage of lump coal and the backlog of a large amount of pulverized coal. In order to change this situation, vigorously developing the pulverized coal molding industry is an important way to resolve this contradiction.
