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).

Boiler Temperature - an overview | ScienceDirect Topics

We could raise the boiler temperature to, say, 300 C but this would elevate the steam pressure to 85 atm. Note that to raise the boiling point a little (76 K or 34%), we cause the boiler pressure to increase substantially (60 atm or 240%) thus demanding a much more robust and …

Steam reheat was introduced in the 1950s and double reheat in the 60s. The more costly options tended to be discounted when oil was cheap, and subsequently as nuclear energy took over base load power generation in many places. An increase in the steam pressure and temperature involves the use of austenitic material in various parts of the system.
