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.

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill startup, stopping coal feed on shutdown, or when equip ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

In pulverized coalfired (PCF) power plants (PPs), coal is pulverized in a mill, and it is then transferred to the burners and furnace volume for combustion. Depending on the physical and chemical properties of the coal, different types of pulverizing systems (, vertical and horizontal airswept ( Fig. 1 a and b )) can be used.
The main functions of a pulverizer are crushing, drying and separating the fine coal particles toward combustion in the furnace. It is a common experience that mill outlet pipes have unequal coal flow in each pipe and contain some coarse particles.
