✦ Synopsis

At&r&--An experimental investigation of the effects of unstable combustion of mixtures of air and natural gas upon the residual quantities of the oxides of nitrogen has been carried out. Measurements were made at approach velocities between 4 and 9 ft/sec. The results indicate that the frequency of the regular perturbations or oscillations in pressure is of greater importance than the magnitude of such fluctuations at frequencies above several hundred cycles per second. At much lower frequencies the magnitude of the pressure perturbations is of much greater importance. The presence of oscillatory . or screaming combustion increases the residual quantities of the oxides of nitrogen by several fold.

Significant variations in the quantities of the oxides of nitrogen were encountered under a single set of-operating conditions.
