5. FANS AND BLOWERS

Fans and blowers provide air for ventilation and industrial process requirements. Fans generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other com-ponents in a fan system. The fan rotor receives energy from a rotating shaft and transmits it to the air. Difference between Fans, Blowers and Compressors

Usage Of Primary Air Fan In Thermal Power Plant

The pulverized coal is carried to the furnace from the coal mill by the fan system. It partially provides the pulverized coal with heat energy before it reaches the boiler. During the transportation of coal, the air from such fans helps the coal to be preheated. This evaporates the moisture present in the coal, removing the stickiness. PA fans ...
