Features of haloalkane effect on the concentration limits and induction time for the ignition of methane–oxygen mixtures

Cover Page

Abstract

A strong difference in the character of admixture effect on ignition by shock wave and spark initiation has been revealed using the haloalkane effect on the ignition of methane–oxygen mixtures as an example. It has been shown that the difference is determined by the presence of considerable concentrations of reactive intermediate species in an initial mixture, the qualitative difference in gas heating modes, and the strong difference between the temperature ranges of the process for two these methods.
