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 classification functions.
