Fuel Character Effects on Current, High Pressure Ratio, Can-Type Turbine Combustion Systems

Abstract

The effect of limited fuel property variation on the performance of current, high pressure-ratio, can-type combustors was evaluated. The TF41 turbofan combustor was employed. This combustor has conventional, dual-orifice fuel injection and film cooling. The combustion zone is approximately stoichiometric at takeoff. Twelve experimental fuels, including JP-4 and JP-8, were tested, Distillation range, hydrogen content, and aromatic type were varied by blending JP-4 and JP-8 fuels with mineral seal oil and two types of aromatic solvents. Performance tests were accomplished at idle, altitude cruise, dash, and takeoff conditions. Sea level and altitude ignition tests were also completed. Fuel fouling and carboning characteristics were established. Combustor operating parameters such as liner temperature, pattern factor, ignition fuel/air ratio, lean blow out fuel/air ratio, and exhaust emissions were correlated to fuel properties. The effect of fuel properties on combustor and turbine hardware durability was assessed analytically.
