Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills to be good for 50 PSI.

The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion. Advantages. Good control on coal fineness.
