Heat rate is a metric that is inversely proportional to power plant efficiency, thus equally crucial. It is a comparison of the amount of heat capable of generating 1 kilowatt-hour (kWh) of power. (3,412 Btu/kWh÷heat rate) × 100 = % thermal efficiency of a power plant. Because of the inverse proportionality to efficiency, it follows that
In the boiler, the rate of steam generation varies according to the combustion heat, flow rate, and the heat transfer surface area used. While the work done is dependent on many factors such as the steam''s relative velocity, reduction in the amount of steam heat in the turbine, the angle of the blade, and the guide vane''s angle at the
