Effect of Prevaporized Fuel on Combustor Performance
Abstract
An experimental investigation was conducted, using the Phillips 2- inch combustor operated under conditions simulating those in modern aircraft turbine engines, to determine the effects of differences in JP fuels on flame radiance and exhaust emissions. Kerosene-type fuels spanning the range in molecular structure (normal paraffins, isoparaffins, cycloparaffins, and aromatics) are used in the investigation. Two programs are included to provide a wide range of operating variables for evaluation of the effects of fuels on flame radiance and emissions. One program covers a broad range of combustor pressure, inlet air temperature, inlet air humidity and two methods of introduction of fuel to the combustor (prevaporized and pressure atomized) and is limited to a single level of heat input for five test fuels. The other program covers a range of heat input rates but is limited in range of inlet air temperature and combustor pressure. Conclusions are presented as to the effects of fuels, prevaporized vs pressure atomized fuel, inlet air humidity, inlet air temperature, combustor pressure and heat input rate on flame radiance and emissions of smoke, NOx, NO, and CO.
