COAL CFB Boiler - Getabecboiler

Steam boilers having an external furnace are generally provided with both Primary ( pa fans ) and Secondary air inlets and both play an important role in the combustion of fuel. Primary air is generally the basic amount of air required for complete combustion of fuel and it depends upon the composition and quantity of fuel required by the boiler.
