Understanding Coal Power Plant Heat Rate and Efficiency

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).

Challenges when Converting Coal-Fired Boilers to Natural Gas

Mar 11, 2019 · Boiler coal consumption calculation formula = boiler power ÷ coal heat value ÷ boiler thermal efficiency. Of course, the boiler unit conversion is uniform when calculating. Taking a 10 ton szl series coal-fired boiler as an example, assume that the anthracite calorific value is 6500kcal/kg, and the coal consumption is 6000000 kcal / h ÷ 6500kcal / kg ÷ 85% = 1086kg / h.
