NO2 Combustor Emissions Investigation.
Abstract
This report presents the results of an experimental program investigating the possibility of NO2 formation within the burners of aircraft gas turbine engines. An environment resembling the cooler regions of the combustor (e.g., the cooling layer) was established to test a proposed mechanism involving: (1) transport of NO from a 'hot' combustor section into a region more thermodynamically favorable for NO2 formation, e.g., the cooling layer, and (2) subsequent reaction of the NO to form NO2 either homogeneously or under the influence of catalysis (heterogeneous or homogeneous). Results of experiments conducted examining this possibility revealed that under the action of hydrocarbons, significant amounts of NO can be oxidated to NO2. The role of Drierite on NO2 adsorption was also investigated. An unverified explanation of this phenomenon is presented involving reaction of NO2 and H2O to HNO3 and NO.
