Combustion and nitric oxide formation are analyzed for an MHD secondary combustor consisting of multi-parallel jets of air injected into a stream consisting of the primary combustor combustion product containing carbon monoxide. The minimum combustor length required for mixing and complete combustion in the limit of fast chemical kinetics is determined. This length is shorter than that required for uniform mixing. It is a moderate function of the jet spacing and is rather strongly dependent upon the stoichiometric air ratio. In the usual operating temperature range of 1600 to 2000/sup 0/K and for the lengths up to about 5m, the NO/sub x/ reactions in the secondary combustors are found to be nearly frozen. Therefore, ignition and combustion, rather than the nitric oxide formation, should be the secondary combustor design criterion.
