TRANSFORMATION OF OXIDES OF NITROGEN COMPOSITION WHILE SAMPLING COMBUSTION PRODUCTS

Combustion products are regularly sampled to determine the concentration of the major products of combustion as well as the concentration of the pollutant species. Nitrogen oxides are especially susceptible to changes in concentration that may occur during transport from the sampling point to an instrument for quantitative analysis. The present study reviews the range of conditions over which nitrogen oxides are sampled in practice, and the variety of chemical transformations that may occur within probes and sample lines. In addition, experimental data are presented for chemical transformations that occur for mixtures common to stationary source monitoring, namely combustion products mixtures containing oxygen at temperatures ranging from 25 C to 400 C.
