Heat Rate is an expression of the conversion efficiency of power generating engines or collectively plants. The typical unit for this is Btu/kWh, or British Thermal Units per kilowatt hour. For example 8,000 Btu/kWh means that 8,000 Btu of heat energy which is input into the engine will result in conversion to 1 kWh of electricity. The heat energy is of course input into the plant by combustion of many different types of fuels.
It should not be misunderstood that using different fuels for the same engine will result in different Heat Rates for the engine. However the Heat Rate may be kept constant or even improved marginally by ensuring the engine is always properly maintained so that all working components are working at their peak efficiency. Obviously a poorly maintained engine will result in a deterioration of its Heat Rate, which means that more fuel will have to be burnt to generate the same amount of electricity.
It is easy to understand why investors in power generation projects look at Heat Rate as a key indicator of the profitability of the plant concerned.

How do radioactive isotopes add to earths heat?
Radioactive isotopes release energy in the form of heat as they break down. Heat itself increases the rate of this break down.
Rising air warmed by the release of latent heat cools at the rate of?
10 K/km (in the troposphere)
What is the heat which travel molecule to molecule?
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
Why cannot you feel warm when you touch a rusty iron nail?
Although the process of rusting does release heat, the precess itself is very slow, so the rate at which the heat is released does not produce a noticeable change in temperature.
What is cooling rate and how is it measured?
it is the rate of heat loss in an element... it can be measured by a thermometer. hope this helps! :)
The wet adiabatic rate of cooling is less than the dry rate?
of the release of latent heat
The wet adiabatic rate of cooling is less than the dry rate because?
of the release of latent heat

Why does the adiabatic rate of cooling change when condensation begin?
When water changes state from a vapor to a liquid it release heat.
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
What is heat rate of steam turbine How to calculate heat rate of steam turbine?
manish
How do you calculate boiler heat rate?
MCF * BTU = MMBTU MMBTU * KWH = Heat rate
What is the heat which travel molecule to molecule?
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
What is the rate at which things heat up called?
Thermodynamics is a study of monitoring heat rate in fluids. This helps you to assess the rate at which certain fluids heat up when exposed to warm tempratures.
How do you calculate the efficiency of a power plant when you know its heat rate?
Efficiency = (860.4*100)/(Heat rate in kCal/kWh) or Efficiency = (860.4*4.18*100)/(Heat rate in kJ/kWh) Ex 1: if heat rate is 2500 kCal/kWh, then efficiency is 34.416% Ex 2: if heat rate is 9000 kJ/kWh, then efficiency is 39.96%
