Pulverizers - Mitsubishi Power

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.

Why Pulverized Coal is Used in a Power Plant - Bright Hub

This is what is special in a coal fired power plant, especially large thermal power plants. Burning the coal in the combustion process to release the energy in the fuel. Why Pulverizing ?
