Transport the pulverized coal from pulverizer to the burners in the boiler. To remove moisture in coal to an acceptable level for firing in boiler. To remove high density inorganics from coal during pulverization. To classify coal particles to the required level of fineness, normally 70 % through 200 mesh and less than 2% on 50 mesh.

The finer the grinding of coal, the more efficient its combustion. The difference is that the highenergy ignition devices which generate sparks replace people's hands. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill • Use: Pulverized coal can be used as a reducing agent by injecting it through the tuyeres.
