  • PULVERIZED COAL FURNACES

    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
