Evaluation of Heat Rates of Coal Fired Electric Power Boilers

boilers and steam pressure. In that study, there were 112 supercritical boilers (about 10% of the total number of coal-fired electric generating units), but they averaged about 750 MW in size. As expected, the supercritical boilers averaged a lower heat rate than the subcritical boilers. In

Bituminous coal - Wikipedia

Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material. Its primary constituents are macerals : vitrinite , and liptinite .
