Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of % or less making the boilers very efficient.

The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
