Objective is to analytically determine the effect of combustor operating conditions on the conversion of fuel-bound nitrogen (FBN) to nitrogen oxides (NO/sub x/. The effect of FBN and of operating conditions on carbon monoxide (CO) formation was also studied. For these computations, the combustor was assumed to be a two-stage, adiabatic, perfectly-stirred reactor. In the first computation, propane-air was used as the combustible mixture and fuel-bound nitrogen was simulated by adding nitrogen atoms to the mixture. The oxidation of propane and formation of NO/sub x) and CO were modeled by a fifty-seven reaction chemical mechanism. Results are reported in this paper for NO/sub x/ and CO formation as a function of primary and secondary stage equivalence ratios and residence times as well as the amount of FBN in the unburned mixture. Comparison of the computed results with experimental data obtained under another part of the CRT program is also shown.
