The heat rate is defined as, HR Qbioler Wnet where Qbioler is the heat transfer rate (Btu/h) to the water in the boiler due to the combustion of a fuel and Wnet is the net power (kW) delivered by the plant. In comparison, the thermal efficiency of the power plant is defined as, nth Wnet Qbioler where the numerator and denominator have the same units. Consider a power plant that is delivering 1000 MW of power while utilizing a heat transfer rate of 3570 MW at the boiler.
