Axial profiles of trace nitrogenous constituents formed and converted in an atmosphericpressure flat flame on a water-cooled burner were determined by direct molecular-beam, mass-spectrometer sampling. The premixed input composition was: 19% H2, 9.5% O2, 0.5% NH3 and 71% Ar. This flame is free of both atmospheric N2 and the oxides of carbon, so that the product N2 and the intermediate N2O were observed without major interferences at masses 28 and 44. A reaction zone, where NH3 and NH2 profiles decrease monotonically toward zero and NO and temperature profiles increase to maxima, extends 2mm above the burner. The measured terminal temperature is 1050 (± 5) K, and the yield of NO claims nearly half the available nitrogen and vastly exceeds the amount of oxidized nitrogen that would satisfy chemical equilibrium. |
