    Pulverized coal power plants are broken down into four categories, with operating temperatures and pressures as a function of the steam temperature and pressure •. Subcritical pulverized coal (SubCPC) plants, below the critical point of water (540 C and 170–220 bar), have an operating efficiency 38 . •.Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, complete drying of coal can be achieved in the mill. This results in increased mill exit.
