Coal is a kind of fuel and industrial materials, which is distributed extensively on the earth. It is widely used in the fields of power generation, chemical industries, and heating because of its low cost and easy exploitation. Lump coal usually is pulverized into powder to improve the combustion and chemical conversion efficacy.
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.
