Understanding coal-fired power plant cycles

Coal-fired power generation plants are most commonly based on pulverised coal combustion (PCC) systems, in which heat from combustion of the coal is used to raise high pressure superheated steam that drives a steam turbine generator. Steam turbine plants have been in use for over a hundred years, and have reached supercritical conditions with
