Temperatures and the concentrations of stable species, such as CO, CO2, CH4, and CH3Cl, have been measured over the height above burner at equivalence ratio of 0.79 (fuel lean) and 1.20 (fuel rich) for premixed, laminar CH4/air and CH3Cl/CH4/air flat flames. A water-cooled quartz sampling micro-probe and gas chromatographic analysis were used for the concentration measurements. Chemical kinetic modeling of these flames with a 279-reaction, 63-species elementary reaction mechanism is performed using the CHEMKIN premixed flat flame code. The results of rate-of-production calculations are analyzed to determine the most important reaction pathways responsible for destruction of the fuels, and the production and consumption of the intermediates. Experimental data show that CH4/air flames doped with CH3Cl have higher CO/CO2 concentration ratios over almost all heights above the burner at the same equivalence ratio, which is consistent with the modeling prediction.
