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).

Steam Heating System Operating Temperature

Steam heating boiler operating temperatures: You won't normally see a temperature gauge on a steam boiler: the boiler has to "boil" water to make steam so it's a safe bet that water in the boiler, when it's making steam, will be around the boiling point.
