Boiler design for ultra-supercritical coal power plants

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).

Understanding Superheater and Supercritical Boiler

Understanding Superheater and Supercritical Boiler. Superheater Boiler. The superheater boiler produces superheated or dry water vapor. This steam stores more heat energy than saturated water steam, characterized by higher enthalpy values. The steam produced by conventional boilers generally only reaches the saturated phase, but in this

Supercritical Rankine Cycle - Nuclear Power

2020-3-25 · The thermal power plants are currently designed to operate on the supercritical Rankine cycle (i.e. with steam pressures exceeding the critical pressure of water 22.1 MPa, and turbine inlet temperatures exceeding 600 °C). Supercritical fossil fuel power plants, that are operated at supercritical pressure, have efficiencies around 43%.
