Abstract:

An experimental and theoretical study has been made of the history of the pollutants carbon monoxide CO, unburned hydrocarbons HC and nitrogen oxides NOx in a turbojet afterburner. Experimental traverses at several axial stations were performed in a simulated afterburner in which exhaust from a J-47 combustor can, operated at medium power, was mixed with fuel spray. Experiments were carried out both in a non-bypass and in a bypass configuration secondary air was mixed with primary exhaust. The theoretical analysis consisted of a computer program for reacting flow with turbulent mixing. Infrared measurements of NO in the combustion tunnel were attempted. Indications were obtained of NO at the 5.3 micron band, but quantitative measurements were not obtained. Author
