Pulverised Coal
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.

Pulverized Coal System Advantages and Disadvantages
Advantages of pulverized coal firing. (1) Greater surface area per unit mass of coal allows faster combustion reactions because more carbon becomes exposed to heat and oxygen. This reduces the excess air needed to complete combustion. (2) Less excess air is required for complete combustion because of greater surface area of fuel exposed.
