Pulverized coal ( pulverized fuel -pf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers ). The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture. The coal is pulverized to a fine powder, usually so that 70% is less than about 75 μm in size, before being

Pulverized-coal-fired boilers emit between 70 and 85 percent of the ash in the coal as fly ash. In contrast, a stoker-fired boiler emits only 3.0 to 50 percent of the coal ash with the flue gas. In addition, the particulate matter generated by stoker boilers tends to be much coarser than the ash from pulverized-coal-fired boilers, and it generally contains considerably more carbon.
