Laser induced fluorescence and absorption measurements of NO in NH3/O2 and CH4/air flames

摘要: Laser diagnostics have been used to probe NO in atmospheric pressure flames. induced fluorescence techniques (LIF) were measure relative concentration profiles of at fuel equivalence ratios φ=1.28, 1.50, and 1.81 NH3/O2/N2 flames φ=1.7 1.8 CH4/air/O2 absorption measurements made derive an absolute a lean flame. This measured agreed well with the calculated equilibrium concentration. The signals from rich then calibrated by comparing that flame where concentrations derived. In decay more rapidly throughout burnt gases than one would expect conventional mechanism ammonia oxidation. suggests new reactions such as NH2+NH2 NH+NH2 ultimately yield N2 are important these LIF on able resolve growth an...
