Efficiency of Thermal Power Station
The overall efficiency of steam power station is quite low (about 29%). The reasons are: (i) huge amount of heat is lost in condenser and (ii) heat losses occur at various stages of any power plant.
It is defined as the ratio of heat equivalent of mechanical energy transmitted to the turbine shaft to the heat of combustion of coal.
(2) Overall efficiency
it is defined as the ratio of heat equivalent of electrical output to the heat of combustion of coal
