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.

Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases …
