Prediction of NOx emissions in gas turbine combustors inclusive of the N2O contribution

Abstract: A model is presented to account for NO emissions due to both the thermal and the nitrous oxide pathways, and to quantify emissions of N2O itself. The model is applied to a hypothetical combustor operating at typical take-off conditions, as high-pressure conditions are expected to emphasize the role of the nitrous oxide pathway. Predictions suggest that this pathway may turn out to be a signicant source in such conditions, contributing about 15 % to total NOx emissions
