Heat Rate Basics – Industrial Wiki – odesie by Tech Transfer

Heat rate is expressed in units of Btu/kWh, and fuel is usually purchased in quantities of million Btus. A reduction in heat rate is simply a reduction in the quantity of fuel necessary to produce a fixed number of kWh. To calculate heat rate deviation cost, it is important to understand that several factors need to be known and understood.

Understanding Coal Power Plant Heat Rate and Efficiency

 The scene: Twenty years ago, a young engineer stands in front of a group of plaques and awards in the lobby of a large coal-fired power plant. She notes with interest that several of them refer to best heat rate awards, and she also notes that the last award is more than three years old. A grizzled station engineer, looking like a coal-dusted Sam Elliott, joins her in front of the display.See more on

Heat rate (efficiency) – Wikipedia

If the heat rate is 7,500 Btu, the efficiency is 45.5% (since 3,412 Btu / 7,500 Btu = 45.5%). The higher the heat rate (i.e. the more energy input that is required to produce 1 kWh), the lower the efficiency of the power plant. Most power plants have a target or design heat rate. If the actual heat rate does not match the target, the difference …
