- Abstract
- Cyanogen and sulfur dioxide were added to fuel-rich, premixed, CH4/He/O2 flames to investigate the effect of fuel sulfur on the distribution of nitrogenous species in the post-flame 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, addition of SO2 caused a significant increase in HCN levels and a decrease in N2 levels in the post-flame region. The data suggests the presence of N2O in the post flame. Furthermore, it is interpreted in the light of literature values of appropriate rate coefficients for mechanisms governing the fate of fuel nitrogen.
