The constancy of the concentration of an inhibitor preventing the ignition of gases

Аннотация

Mechanisms of consumption of inhibitors in gas mixtures in different combustion modes—ignition prevention and suppression of flame propagation and detonation—have been revealed. It has been found that no more than a few hundredths of a percent of the initial reagents, including the inhibitor, are consumed for the prevention of ignition. In suppression of flame propagation and detonation, the inhibitor is consumed only in chain termination reactions. Oxygen is additionally consumed only in reactions with the products of incomplete oxidation of the inhibitor. The results have been interpreted in the framework of the theory of nonisothermal chain processes.
