Usage Of Primary Air Fan In Thermal Power Plant

2021-7-5  PA Fan System: Main Functions. Supplying air for burning the fuel and helping in the combustion process. 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,
