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. The classification function plays the important role of ensuring that only fine particles are sent to the boiler. A rotating-type classifier ensures that only fine particles pass through and cuts coarse particles through the opposing balance of centrifugal force and centripetal force produced by a blade rotating at several dozen rpm and the flow of air.
A vertical-type pulverizer bites into coal between a rotating table and roller to pulverize the coal through the action of crushing and grinding. Mitsubishi Power offers a varied lineup from small to high capacity through two types of pulverizer, MVM and MPS.
