Heat rate (efficiency) - Wikipedia

Heat rate is a term commonly used in power stations to indicate the power plant efficiency. The heat rate is the inverse of the efficiency: a lower heat rate is better. = The term efficiency is a dimensionless measure (sometimes quoted in percent), and strictly heat rate is dimensionless as well, but often written as energy per energy in relevant units. In SI-units it is joule per joule, but often also expressed as

If the actual heat rate does not match the target, the difference between the actual and target heat rate is the heat rate deviation. Most heat rate deviations are often small in relation to the overall heat rate. For instance, a 70 Btu/kWh deviation is only 1% of a 7,000 Btu/kWh heat rate that is normal for a combined cycle plant.

Heat Rate Formula Steam Turbine - Definition, Formula And …

c = specific heat capacity in btu/lb ∘F, ΔT is the temperature difference in ∘F. Question 1: Calculate the heat rate if steam enters a turbine at 400oF at atmospheric pressure. Steam at 500 lb flows through the turbine each hour during normal operation. Given parameters are, Ws = 500 lbs/hr. ΔT = 400 – 200. We have the Formula,

How to Calculate Boiler Heat Input Rate | Sciencing

Divide this heat gain by the length of time for which the boiler runs, measured in second. For example, if the boiler runs for 1,800 seconds, dividing 12,558,000 by 1,800 gives 6,977, or a little under 7,000. This is the heat input rate, measured in joules per second, or Watts. Divide the heat input rate by 1,000 to convert it to kilowatts

The heat rate is defined by: A means of measuring cycle heat rate having been defined, consideration can now be given to variations between the design heat rates quoted by the turbine manufacturers and the heat rates achieved in operation. First, consider the variation of the hourly heat consumed by the turbine-generator with the load produced
