function of pulverizer in coal preparation

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.

Coal Pulverizer Pall

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.

Fire and Explosion Prevention in Coal Pulverizing Systems

Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent. All these factors make the coal/ air mix- ture easier to ignite and, once ignited, more likely to detonate and cause an explosion.
