Abstract
This study examines the effects of probe configuration and combustor operating parameters on NO/NO/sub 2/ distributions in flames. A fundamental understanding of physical and chemical phenomena pertinent to NO/sub 2/ measurement in combustion systems is important because of the gas's significant role in smog formation and in combustion processes, as well as its hazard to human health. A flat flame burner system was modified, refurbished and optimized for operation over a range of reaction throughputs, fuel-air equivalence ratios, and combustion processes. Comprehensive NO/NOx measurements were made using various probes. Low NO/sub 2/ levels were recorded with cooled and uncooled quartz probes; uncooled stainless steel probes showed virtually no differences between NO and NOx; water cooled stainless steel probes measured significant NO/sub 2/ concentrations; water cooled sterling silver probe results were similar to those of cooled stainless steel probes. Data indicate that probe configuration, burner pressure, and stoichiometry significantly affect NO/NOx measurements. A kinetic model was developed to clarify and explain sampling probe effects on NO/NO/sub 2/ interconversions within the probes.
