Heat rate reduction in thermal power generatio

2015-8-6 · Heat rate is the heat energy input per unit of electrical energy output, or fuel consumption rate for specific levels of power plant output. Heat rate is also the inverse of plant efficiency. Lower is better. For a coal-fired plant, fuel is by far the largest expense item, representing about 55% to 75% of total plant
