It is shown that the oxidation of gas outside the ignition region consists of isothermal chain processes with no progressive self-acceleration. The functional nature of the rate of the reaction’s temperature dependence under these conditions is det

It is shown that the strong dependence of the rate of gas-phase combustion reactions on temperature is determined by the high values of the reaction rate constants of free atoms and radicals. It is established that with a branched chain mechanism, a

The combustion of hydrogen-air mixtures near the lower composition flammability limit in cylindrical reactors of various diameters is studied. The speed of flame propagation in the horizontal direction is lower than that in the upward direction. Chro

The competition between chain propagation and chain termination reactions was shown to play an important role in gas-phase combustion. Conditions under which this competition to a substantial extent determined the critical ignition conditions and the

The fundamental regularities of hydrogen/oxygen combustion are considered, which unambiguously indicate the branched chain character of the process at atmospheric pressure. It is noted that, in the general case, the ignition conditions are determined

The normal rate of combustion S ui of rich near-limit hydrogen-oxidizing medium-retarder mixtures was determined experimentally. The oxidizing medium was a mixture of nitrogen and oxygen with oxygen contents of 15, 20.6, and 25 vol%; the retarding ag

It is shown that, in hydrogen-oxygen mixtures, under the conditions when the rate of reaction chain termination is higher than the rate of chain branching, the characteristic reaction time is hundreds of seconds even in the immediate vicinity of the

The absence of correlations between the heat of combustion of substances and substance combustion characteristics is shown to be caused by the special features of competition between reaction chain branching and termination, including partial partici
