Coal-Fired Boiler - an overview | ScienceDirect Topi

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).

Calculating Boiler Efficiency - forbesmarshall.c

Boiler efficiency is a combined result of efficiencies of different components of a boiler. A boiler has many sub systems whose efficiency affects the overall boiler efficiency. Couple of efficiencies which finally decide the boiler efficiency are- H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of
