EFFECT OF OXYGEN CONCENTRATION OF THE INLET OXYGEN-NITROGEN MIXTURE ON THE COMBUSTION EFFICIENCY OF A SINGLE J33 TURBOJET COMBUSTOR

摘要

An investigation was conducted to determine the importance of molecular-scale processes in the over-all turbojet combustion process. The effect of oxygen concentration of the inlet oxygen-nitrogen mixture on the combustion efficiency of a single J33 combustor was determined for combustor-inlet pressures from 12.0 to 21°4 inches of mercury absolute and a range of fuel-flow rates. The combustor-inlet tempera¬ture and weight-flow rate of the oxygen-nitrogen mixture were held con¬stant at 40° F and 1.0 pound per second, respectively- Attempts were made to correlate combustion efficiency with selected fundamental com¬bustion properties and with a simplified reaction-kinetics equation.
