The Efficiency of Power Plants of Different Types
The overall coal plant efficiency ranges from 32 % to 42 % This is mainly dictated by the Superheat and Reheat steam temperatures and Superheat pressures Most of the large power plants operate at steam pressures of 170 bar and 570 °C Superheat and 570 ° C reheat temperatures The efficiencies of these plants range from 35 % to 38 %
