INHIBITION OF FLAME REACTIONS.
Abstract
The study of flame inhibition by dispersed solid particles was made in a constant flow system. Solid particles act both by a cooling effect and by a more specific surface destruction of the free radicals which propagate the chain reaction. A theoretical formula is proposed which allows the calculation of the necessary amount of powder which extinguishes the flame. Very good agreement with the experimental data was observed. Homogeneous inhibition by means of additives was investigated and more expecially the behaviour of ternary mixtures (two fuels and one oxidizer of the reverse) at the flammability limits. The reciprocal influence of additives on the flammability limits is to be ascribed both to a temperature effect and to a more specific effect on the reaction kinetics; the substitution of more by less reactive chain carriers (free radicals) takes place.
