Pulverizers. Boilers. To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and ...

pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion. This section further reduces the coal size by attrition and by impact of coal on the moving and stationary parts.
