Coal Pulverizer Mitsubishi Heavy Industries, Ltd. Global

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification.

Pulverised Coal an overview ScienceDirect Topics

Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuel-firing systems: bin system and direct-firing system. Coal feeders are either the volumetric or gravimetric type.
