Estimation of Gas Turbine Fuel Rates

In this post I want to share how to estimate gas turbine fuel rates. We use heat rates to estimate gas turbine fuel rates.

Heat rate is a measure of thermal efficiency or the amount of energy (in the form of fuel) which must be input to the gas turbine to produce the output power. Heat rate is usually expressed in terms of Btu/(hp.hr) or Btu/(kW.hr) based on the lower heating value of the fuel. Heat rate and thermal efficiency are related as follows:

Gas turbine heat rates vary considerably. They are function of gas turbine rating and type of turbines, which are simple cycle, jet turbine simple cycle, or regenerative. Read More
