The steam boiler blower (also known as the supply fan) is the core auxiliary equipment of the boiler and is called the “lung of the boiler”. It is mainly responsible for forcibly sending combustion-supporting air into the furnace to ensure the complete combustion of fuel.
Function: Supply air for combustion assistance, regulate the combustion intensity, and cooperate with the induced draft fan to maintain negative pressure in the furnace chamber
Common type: Centrifugal fan
Matching: Generally used together with the induced draft fan, one for supply and one for extraction
Key point: The air volume and air pressure should match the tonnage of the boiler. Biomass boilers usually require a larger air volume
