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 .
