Fuel Modification for Abatement of Aircraft Turbine Engine Oxides of Nitrogen Emissions

Abstract

The report describes a broad experimental program that was undertaken to assess the feasibility of reducing NO(x) from aircraft gas turbine engines by fuel modification. The Esso High Pressure Cannular Combustor was used to simulate the characteristic emissions of gas turbines at full power operation. Over 70 fuel modifications were tested using Jet A as the base fuel. Soluble compounds of cobalt, iron, magnesium, and copper reduce NO(x) by as much as 30% when added to the fuel at a treat rate of up to 0.5% (w). None of the investigated additives were fully acceptable because of the relatively low NO(x) reduction that was obtained even with high additive treat rates. A simple expression was derived which is useful in estimating NO levels in gas turbine combustors when equilibrium NO(x) concentrations and temperature are known.
