How to Understanding Coal Power Plant Heat Rate and

Nov 08, 2016 · This article uses the U.S. format. iGAIndustrial Steam Boiler. Because approximately 3,412 Btu/hr equals 1 kW, we can easily determine the thermodynamic efficiency of a power plant by dividing 3,412 by the heat rate. For example, a coal power plant with a heat rate of 10,000 Btu/kWh has a thermal efficiency of 3,412/10,000, or 0.3412 (34.12%).
