Factors Controlling Pollutant Emissions from Gas Turbine Engines,

Abstract

Primary pollutants emitted by aircraft gas turbine engines are carbon monoxide, hydrocarbons, aldehydes, smoke, particulates, and nitric oxide. Factors controlling emissions of these pollutants are analyzed on the basis of aircraft engine exhaust composition and laboratory studies of gas turbine combustion processes. Moreover, an analytical prediction of the effect of aircraft operating parameters on the emission of nitric oxide is also given. Operational conditions and engine parameters such as ambient temperature, pressure, and humidity, flight altitude, flight Mach number, water injection, fuel properties, and combustor characteristics have been studied analytically, yielding rational criteria for the prediction of their effect on the emission of nitric oxide.
