So youd like to run an old coal fired power station

Sep 08 2017 · The furnaces and boilers are the most integrated part of a coal fired power station. They endure remarkable thermal and corrosive stresses and as such have a finite life. They can be repaired to some extent but are generally not economically replaceable so the condition of the boilers is critical to the durability of any power station.

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).
