GAS TURBINE AND JET ENGINE FUELS

Abstract

Flame radiation was measured from gas turbine type combustion processes to indicate the effect of fuel composition. Comparisons of full-scale turbojet single combustor (P+W J-57 and GE J-79) data and a laboratory scale (2-inch) combustor data were made. The correlation between measurements of total flame radiant energy and combustor liner metal temperature was essentially a straight line. The relationship betwe n flam radiation, or liner temperature, and Luminometer Number fuel ratings was studied. No significant reduction in flame radiation results from using fuels having Luminometer fuel ratings above 100. The effect of increased combustor operating pressure (to 15 atm.) on flame radiation, and an interpretation of the significance of Luminometer Number fuel ratings with high pressure combustion was also studied. The performance characteristics of Phillips 2-inch combustor has been shown to simulate that of the full-scale turbojet combustors satisfactorily for research studies of the burning quality of jet fuels.
