Abstract:

An experimental investigation was conducted, using the Phillips 2-inch combustor operated under conditions simulating those in modern aircraft turbine engines, to determine effects differences in JP fuels can have on flame radiance and exhaust emissions of nitrogen oxides, carbon monoxide, unburned hydrocarbon and soot Kerosine-type fuels spanning the range in molecular structure were prevaporized to minimize effects of differences in their physysical properties. On the basis of a preliminary program, an experiment was designed to evaluate effects on flame radiance and exhaust emissions of five fuels operated at all combinations of four levels of combustor pressure, four levels of inlet air temperature, and three levels of inlet air humidity. With the combustor and operating conditions used, unburned hydrocarbons in the exhaust were negligible. Emperical equations were developed for each of five responses in terms of operating variables and fuels. It was concluded from the data obtained that total radiant energy and smoke emissions decreased with an increase in fuel hydrogen content and NOx, NO, and CO emissions are essentially unchanged with changes in fuels. The effect of combustor operating variables on flame radiance and exhaust emissions was evaluated. A small exploratory program was conducted to evaluate the relative effectiveness of two smoke abatement additives and to evaluate the conversion of fuel nitrogen to NOx.
