What Are The Advantages Of Forced Draught System?

1 Answer

Answer :

 Since the fan handles cold air, the fan size and the power required are less.
 No need of water cooled bearings because the air being handled is cold air,
 Pressure throughout the system is above atmospheric pressure so the air leakage into the furnace is reduced.
