Fuel Effects on Gas Turbine Combustion

Fuel Effects on Gas Turbine Combustion Analysis of the experimental data acquired during Wright-Patterson Aero Propulsion Laboratory sponsored programs on the effects of fuel properties on gas turbine combustion has led to the derivation of quantitative relationships between several aspects of combustion performance and the relevant fuel properties, combustor design features, and combustor operating conditions. It is concluded that combustion efficiency, lean blowout limits, lean lightoff limits, and pattern factor are only slightly dependent on fuel chemistry, but are markedly affected by the physical fuel properties that govern atomization quality and fuel spray evaporation. Introduction For the gas turbine and, in fact, for most other forms of heat engines, the most important fuel issues of today are those of cost and availability. The measures now being taken to ensure future supplies of fuels for gas turbines, in addition to various forms of fuel conservation, include the exploitation of alternative fuel sources and the acceptance of a broader specification for aviation fuels. These developments highlight the need for prediction techniques that will allow the impact of any change in fuel specification on hardware durability and combustion performance to be estimated accurately in the combustor design stage.

Abstract

Analysis of the experimental data acquired during Wright-Patterson Aero Propulsion Laboratory sponsored programs on the effects of fuel properties on gas turbine combustion has led to the derivation of quantitative relationships between several aspects of combustion performance and the relevant fuel properties, combustor design features, and combustor operating conditions.
