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).

Thermal energy storage (TES) - Aalborg CSP

Instead of using coal as the base load fuel power should be stored in molten salt during periods of surplus electricity in the grid and discharged when the green energy supply is low and the electricity demand is high. Replacement of the existing coal-fired boiler plants can be achieved through a gradual phase-out based on recycling.
