For low volatile coals, it is recommended that the size of the pulverized coal be finer, or 75% through a 200 mesh screen. And for anthracite fuels with volatile content down to the 2 to 10% range, we would recommend 85 to 90% through a 200 mesh. In addition some sustaining fuel (oil) may be re- quired for good combustion.

The raw coal is then fed into the pulverizer along with air heated to about 650 F (340 C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal powder to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
