1.1 Coal-fired Power Plant Scope Description The concept for the "Small -Scale Flexible Advanced Ultra -Supercritical Coal-Fired Power Plant" is a pulverized coal power plant with superheat (SH) temperature/reheat (RH) temperature/SH outlet pressure of 1202°F/1238°F/4800 psia (650°C/670°C/330 bar) steam conditions, capable of
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 ).
A small coal fired boiler and coal hopper is installed next to the house, which automatically feeds coal into the burner, and controls it on a demand basis. Ultimately, the burning coal heats the water which is then circulated throughout the whole house. When the water returns, it is then ready to be reheated, and the process starts again.
