What Is FD Fan?
Forced draft fans, also called pressure blowers or FD fans, focus the pressure and volume at the outlet of the fan to push air through a system, creating positive air pressure.
What Is The Function Of FD Fan?
Forced Draft Fans (FD) supply the air necessary for fuel combustion by pushing air through the combustion air supply system and into furnace. These fans are located at the inlet of boiler to push high pressure fresh air into combustion chamber, where it mixes with the fuel to produce positive pressure.

How Does FD Fan Works?
An FD fan draws air from the atmosphere and forces it into the furnace through a preheater. These fans are located at the inlet of the boiler to push high pressure fresh air into combustion chamber, where it mixes with the fuel to produce positive pressure.
Difference Between FD Fan And ID Fan:
ID fan is basically mentioned here for Induced draft fan and ID fan is always located between dust collector and chimney. ID fan will take the hot flue gases from furnace via dust collector (dust separation system or Fume Extraction system) and will deliver to chimney. ID fan will handle the flue gases i.e. hot air.
