Composition and Photochemical Reactivity of Turbine Engine Exhaust.
Abstract
This study was carried out to augment the results of an earlier investigation of turbine engine emissions. Experiments were conducted to investigate the photochemical reactivity and biological activity of exhaust from a full-scale 60 deg. sector combustor from a TF-39 turbine engine. All experiments were carried out at idle power setting. The study utilized exhaust from two conventional petroleum fuels (JP-4 and JP-5) and a shale fuel meeting JP-4 specifications. Photochemical reactivity was studied with two large (8 cum 3)n Teflon outdoor environmental chambers. Photochemical reactivity is defined for purposes of this study as the maximum ozone concentration produced during a one day irradiation in natural sunlight. Experiments were undertaken with a TF-39 combustor operating on JP-4 and JP-5 fuels, for comparison with pervious studies of a full-scale TF-39 engine. The combustor exhaust was more effective than exhaust from the full-scale engine, regardless of which fuel was burned. The combustor exhaust was 60 percent more reactive than engine exhaust for JP-5 fuel, and between 30 and 100 percent more reactive for JP-4 fuel. The photochemical reactivity of exhaust generated from a shale oil-derived fuel meeting JP-4 specifications was studied. Exhaust from the shale fuel was no more reactive than exhaust from petroleum fuels, and under some circumstances was actually less reactive. The shale fuel exhaust also generated less secondary aerosol than exhaust from the petroleum fuels.
