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).

Steam Generation - an overview | ScienceDirect Topics

Steam generation in a pulverized coal-fired boiler is accomplished in a configuration of thermal-steam/water sections, which preheat and evaporate water, and superheat and reheat steam. An example of a coal-fired utility boiler is shown in Fig. 4.4 (the fundamentals of steam production and energy flow were discussed in Chapter 4).
