Popis: The article presents the results of the experimental and numerical studies of the reaction mechanisms of chemically active combustion inhibitors and fire retardants in flames. The chemical processes occurring in flames with the introduction of additives of various types of inhibitors—phosphorus- and metal-containing compounds, the mechanism of their transformation, the mechanism of the effect of these compounds on the combustion rate, and the structure of hydrogen and hydrocarbon flames—are considered. The main results of the experimental and theoretical studies, as well as the modeling of the combustion chemistry of hydrogen and hydrocarbon mixed and diffusion flames with and without additives of chemically active inhibitors, are described. It is shown that not only inhibitors in hydrogen and hydrocarbon flames but also fire retardants in polymer flames act by a chain mechanism as a result of the catalysis of the recombination of atoms and radicals. The prospects for the practical application of chemically active inhibitors as flame arresters and fire retardants are discussed.
