In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area. These primary air fans produce a high pressure to push the coal and air mixture through pulverizer into the furnace. The most common configuration of the draught fans used as a PA fan is the backward curved centrifugal fan.

Seal air blowers eliminate leakage from pressurised air systems, typically in power generation plant coal mills. Dust can enter the mill roller and cause problems where blowers are not used. Guillotine dampers usually require seal air blowers to create a barrier of air at pressures above that of ordinary system operating pressure.
