Primary air ( pa fan) and Secondary air fan have an important role to play in fuel combustion and must be provided in different ratios according to the fuel quantity. PA or Primary Air fans are important item in a thermal plant ( boilers) as it lifts and carry coal to destination.
The air intake pipe is welded with a steel plate, the inner wall is covered with heat-resistant concrete, and a sealing device is installed at the connection with the hollow shaft to prevent the cold air from entering. Main bearing: the air-swept coal mill is supported by the main bearing. The main bearing adopts a large hollow shaft diameter ...
Axial fans, as the name implies, move an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, much like a propeller and an airplane wing. Although they can sometimes be used interchange-ably with centrifugal fans, axial fans are commonly used in "clean air," low-pressure, high-volume

The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.
Air heater leakage has a huge effect on a power plant's heat rate, required fan capacity, coal drying and mill performance, precipitator/scrubber efficiency, and the like.
