Nitric Oxide Formation in Laminar Diffusion Flames

A vertical coaxial burner has been used to study nitric oxide formation in diffusion flames. Localized combustion gas samples extracted from the diffusion flame by means of a quartz microprobe have been analyzed for NO as well as for the species CO, CO2 N2, O2 and CH4, the fuel employed. In this manner it has been possible to establish detailed radial profiles for each of the above species. Concomitant temperature profiles have been established through use of a 0.001 inch diameter Pt/Pt-10%Rh thermocouple.

Experimental results indicate that in diffusion flames of this type NO formation occurs in a narrow region corresponding to that of maximum temperature. It is of particular interest that so-called “prompt” NO formation within the highly reactive flame zone is not observed.
