Fire and Explosion Prevention in Coal Pulverizing Systems

today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment. Hence there is the continual danger of fires and, under certain conditions, explosions. Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire.

Mitsubishi Power Pulverizers

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.
