| Abstract | The paper gives results of adding cyanogen and SO2 to fuel-rich, premixed CH4/He/O2 flames to investigate the effect of fuel sulfur on the distribution of nitrogenous species in the far postflame region. Probe sampling and gas analysis were used to determine profiles of HCN, N2, NO, and NH3, as well as CO, CO2, CH4, and C2H2. At all equivalence ratios examined (phi = 2.8, 1.71, and 1.44), adding SO2 caused a significant increase in HCN levels and a decrease in N2 levels in the postflame region. At phi = 1.71, the data suggest the presence of N2O in the postflame. Experimental results are interpreted in the light of literature values of appropriate rate coefficients for mechanisms governing the fate of fuel nitrogen.
