Abstract: The paper discusses the possibility of the existence of two kinetic regimes and critical conditions of thermal chain explosion during wave propagation of flame over hydrogen–air and methane–air mixtures. It is shown that experimental data do not confirm the existence of t he two kinetic regimes. For fuel mixtures in sealed vessels under gravity, two combustion regimes exist that are not related to kinetic characteristics.

Keywords: chain thermal explosion, kinetic regime, flame propagation, convection limit.
