Selective Oxidation of Hydrogen in Rich Hydrogen-Methane-Air Flames

摘要

Numerical simulation studies of flame propagation using the tracer method have shown that in flames of rich hydrogen,methane,and air mixtures there is selective oxidation of the initial molecular hydrogen.The combustion products contain superequilibrium concentrations of water formed from the initial molecular hydrogen and hydrogen formed from methane in the reaction zone,resulting in superadiabatic temperatures of the flames considered.
