Dec 02, 2021 · Answer (1 of 5): 'Natural' draft draws flue gases out of the fire box (combustion chamber) and through the heat exchanger by the natural tendency of heated (less dense) combustion gases to rise (convection). 'Forced' draft employs a fan to push atmospheric air into the fire box and move hot combuGet Price
This is more common with larger boilers where the flue gases have to travel a long distance through many boiler passes. The induced draft fan works in conjunction with the forced draft fan allowing the furnace pressure to be maintained slightly below atmospheric. Firetube boilers The next stage in the process is to boil water and make steam. Get Price
Apr 20, 2020 · The key difference between a forced draft and an induced draft fan is, FD fan forces outside air into the heating system whereas an ID fan draws flue gases from the system out into the atmosphere. Both FD fan and ID fan operate in such a manner that it balances the air system in the boiler to make the combustion process efficient.Get Price
Aug 05, 2007 · Before they were applied to air-cooled units, Induced or Forced Draft fans were applied to Boilers for furnishing combustion air and they still are, to this day.

May 14, 2020 · The difference between induced or forced draft. Induced draft implies an inlet fan placed on top of the cooling tower and the creation of low pressure. Forced draft means an exhaust fan placed at the base of the cooling tower which then causes overpressure.Get Price
How Draft Controls Work Static pressure of the cool air (1) Illustration A exerts pressure on the outside of the furnace or boiler, the breaching, and stack. The pressure difference between the room air and heated gas (air) causes products of combustion (2) to flow (draft) through the unit and rise through the breaching and chimney.Get Price
The Importance of Operating with Proper Furnace DraftGet Price
The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft.
