Abstract

Abstract Experimental data are presented on the formation on NO, N 2O, NH 3, and HCN from an oil spray flame together with the effect of staging the combustion air on the in-flame concentrations of these species. By staging up to 40% of the combustion air a 45% reduction in the emission of NO was achieved for a flame characterized by a lower axial NO concentration and HCN NH 3 ratio. N 2O as an active species was only observed in the early part of the flame, with the staged flame producing the higher concentrations. Final flue gas emissions of N 2O were less than 2 vpm for the range of experimental conditions studied.
