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).
The CCS operates much like a conventional pulverized coal-fired burner, using typical off-the-shelf hardware, familiar to the operators. It fires pulverized coal with some limestone added to provide the necessary calcium to capture the sulfur in the coal, developing a clean, hot, fuel-rich gas that enters the boiler furnace. Subsequent over-fire
