Coal-Fired Boiler - an overview | ScienceDirect Topics

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).

PULVERIZED COAL FURNACES - Thermopedia

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 carried by part of the combustion air stream to the
