Primary Air Fan and Secondary Air Fan are the different names of Forced Draft Fan. They all may be installed in the same Steam Boiler Assembly but they all operate at different levels of flow (m3/hr) and Head generated (mmwc).

Forced Draft Fan is a type of fan supplying pressurized air to a system. In the case of a Steam Boiler Assembly, this fan is very important. As we know, for a Steam Boiler to generate steam, combustion must occur, be it any fuel (wood/coal/rice husk/pet coke/LDO/Furnace oil)
