Data on the parameters of combustion and detonation of single-fuel systems methane–oxygen (air) and hydrogen–oxygen (air), as well as double-fuel systems methane–hydrogen–oxygen (air) with variation of the ratio between the initial species are presented. The influence of combustible system preheating on the parameters of detonation and combustion products is analyzed for fuel-lean, stoichiometric, and fuel-rich mixtures. It is found that preheating has a strong effect in fuel-lean combustible systems, which is manifested as reduction of the critical energy of initiation by several orders of magnitude.
