      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 ).

      Supercritical coal plant - Energy Education

      Supercritical coal plant. Figure 1. RDK-8, a supercritical coal plant in Germany achieves thermal efficiency of 46%. Supercritical coal plants are a type of coal-fired power plant used in more modern designs. They differ from traditional coal power plants because the water running through it works as a supercritical fluid, meaning it is neither a liquid or a gas.
