How Power Plant Boiler Works? - Bright Hub Engineering

The fluidized bed combustion (FBC) takes place at about 840°C to 950°C for coal. Since this temperature is much below the ash fusion temperature, melting of ash and associated problems are avoided. Main reasons for consideration of Fluidized bed combustion Boiler :-Liberty of fuel choice – Normally fuel burns at 700 to 900 Deg C.

Ash Fusion Temperature - 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).
