Current design and construction of coal-fired power plant
The overall thermal efficiency of some older, smaller units burning, possibly, poor quality coals can be as low as 30%. The average efficiency of larger, subcritical plants burning higher quality coals is in the range 35–36%. Subcritical units have evaporator pressures below the critical pressure of water (22.1 MPa).
