The explosibility of the coal used in the system was measured, and the hazards of the process were analyzed. Explosion prevention and protection methods ap-plied in the process were described including atmospheric inerting, powder inerting and venting. Atmospheric inerting is the main method to prevent dust explosions in this proc-ess.

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. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...
