Primary air feeds the coal pulverizer and acts as a carrier and dryer for the coal moving to the burner. An exhaust fan pulls the coal dust from the pulverizer and blows it through pipes into the furnace where it ignites to heat the boiler water. Secondary air is used to maintain the furnace flame and tertiary air surrounds the boiler wall.
