Boiler and Condenser Pressures - Rankine Cyc

Supercritical fossil fuel power plants, that are operated at supercritical pressure, have efficiencies around 43%. Most efficient and also very complex coal-fired power plants that are operated at “ultra critical” pressures (i.e. around 30 MPa) and use multiple stage reheat reach about 48% efficiency. Supercritical Water Reactor – SCWR

Boiler Efficiency - an overview | ScienceDirect Topi

3.2.6 Thermal efficiency of conventional power plants. The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.
