Abstract
The kinetics and mechanism of chemical reactions in the H2/O2/N2 flame were studied experimentally and by simulating the structure of premixed laminar flat atmospheric H2/O2/N2 flames of different initial compositions. The concentration profiles for stable compounds (H2, O2, and H2O), H atoms, and OH• radicals in flames were measured by molecular-beam sampling mass spectrometry using soft electron-impact ionization. The experimental data thus obtained are in good agreement with the results of simulations in terms of three familiar kinetic mechanisms, suggesting that these mechanisms are applicable to the description of the flame structure in hydrogen-oxygen mixtures at atmospheric pressure.
