Fuel Property Effects on Diesel Engine and Gas Turbine Combustor Performance.
Abstract
In this test program, four military engines and a gas turbine combustor were run to determine the effects of fuel properties on combustion performance. During this program, 18 test fuels were prepared with properties extending beyond the range of the specifications of diesel fuels. Diesel engine performance data were analyzed statistically, and regression equations were obtained for each engine expressing load in terms of speed, energy input, cetane number, kinematic viscosity, 10-percent boiling point, and aromatic content. Combustion performance measurements in the T-63 gas turbine combustor included flame radiation, exhaust smoke, gaseous emissions (THC, CO and NOx), combustion efficiency, and ignition properties. The atomizing characteristics of the test fuels were examined with a particle sizing system based on forward-angle diffraction, and the results were correlated with the ignition properties of the fuels. Flame radiation and exhaust smoke were correlated with H/C ratio of the fuel. Viscosity and end point work were used as correlating parameters for THC and CO emissions, and combustion efficiency. Significance of the results was discussed, and recommendations for further testing was presented.
