Chemical Control of Combustion, Explosion, and Detonation of Gases

Abstract

The identification of the chain origin of gas combustion at atmospheric and elevated pressure has opened up new aspects of the theory and wide-ranging possibilities for effectively managing the processes of combustion, explosion, and detonation by controlling the branching and loss rates of active intermediate particles, such as atoms and radicals, by using inhibitors and promoters. In this paper, we briefly describe methods for preventing fires and explosions of methane-air mixtures, including those in coal mines, ignition and explosion of hydrogen-air mixtures, and the transition of combustion to detonation in the current ramjet engine model. The results of interdepartmental tests and experimental data illustrating the destruction of a stationary detonation wave by the small impurities of the lower hydrocarbons are given.
