NITROGEN OXIDE CHLORINE INTERACTIONS IN A LABORATORY SWIRL FLAME COMBUSTOR/

An experimental and theoretical investigation was conducted examining the effect of chlorine (Cl) on nitrogen oxide (NO) emissions from a pr actical combustor. Experiments consisted of both parametric and detail ed studies on an 82 kW rated swirl flame laboratory combustor. Theoret ical efforts consisted of detailed kinetic modeling using validated ki netic mechanisms obtained from the literature. Both the experimental a nd theoretical work led to essentially negative results, namely, that NO/Cl interactions are unlikely to influence NO emissions under most c onditions of interest. Kinetic modeling provided useful insight and wa s able to simulate trends revealed by the data. Additional calculation s from kinetic modeling then suggested that Cl might enhance staging e ffectiveness, under severely reducing primary stage conditions.
