Thermal Power Plant
Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
