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.

Fan and blower selection depends on the volume flow rate, pressure, type of material handled, space limita-tions, and efficiency. Fan efficiencies differ from design to design and also by types. Typical ranges of fan efficiencies are given in Table 5.2. Fans fall into two general categories: centrifugal flow and axial flow.

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
