Abstract : Apparent flame strength (AFS) measurements were made nn the ammonia- nitric oxide and ammonianitrous oxide flame reactions in the opposed jet reaction at pressures ranging ,rom 100 to 745 torr. The pressure dependencies of the apparent flame strengths of these systems gave overall reaction orders of 1. 56 and 2.0 for NH3-NO and NH3-N2O counterflow diffusion flames, respectively. The overall stoichiometry of the NH3-NO flame extinguishment can be represented by the following equation. 1.5 NH3 + NO yields 1.25 N2 + 1.25 H2 + H2O. The volumetric reaction rate for this flame reaction was computed using Spalding's analysis of the opposed-jet flame. At 1 atmosphere, an apparent flame strength of 0.65 gm/sq cm-sec corresponded to a volumetric reaction rate of 2.93 gm/cu cm-sec release rate of 7,220 cal/cu cm-sec.
