Abstract

The influence of the structure of perfectly premixed flames on nitrogen oxide (NO_x) formation is investigated theoretically. Calculations for a mixture temperature of 630 K, an adiabatic flame temperature of 1840 K and 1 and 15 bars combustor pressure are presented. Either no relevant influence or an increase in NO_x production over that of the one-dimensional laminar flame was found. The investigation was also extended to lean-lean staging, since a higher NO_x abatement potential can be expected in principle. As long as the chemical reactions of the second stage take place in the boundary between the fresh mixture of the second stage and the combustion products from upstream, no advantage can be expected from the lean-lean staging.
