Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C ( Shen and Cheng, 2004 ).

The design and operation of a pulverized coal fired boiler is more dependent upon the effect of mineral matter in the coal than any other single fuel property. The sizing of the boiler and its design are largely determined by the behavior of the coal mineral matter as it forms deposits on the heat transfer surfaces in the lower furnace.

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
