     · Before the coal mill we mix both Cold PA and Hot PA and this optimum temperature air is used for drying purpose of coal, which is around 80°C. PA system also varies from design to design. In Cold PA system, PA fan takes air suction from atmosphere and some amount of this air goes to APH(Air Pre Heater) and other half of the air directly goes to a header called Cold PA Header.
