The role played by self-inhibition in combustion processes

The absence of correlations between the heat of combustion of substances and substance combustion characteristics is shown to be caused by the special features of competition between reaction chain branching and termination, including partial participation of fuels in the inhibition of their oxidation. By way of example, differences in the characteristics of combustion of hydrocarbons and hydrogen at atmospheric pressure and the mechanisms of the development of chain avalanches in these processes are considered.
