N1 - The data on methane-oxygen (air) and hydrogen-oxygen (air) systems and on two-fuel methane-hydrogen-oxygen (air) systems were obtained within the framework of the project ‘‘Basic research of combustion and detonation processes as applied to the development of fundamentals of power engineering technologies’’ of the Ministry of Science and Higher Education of the Russian Federation (Agreement no. 075-15-2020-806 dated 29.09.2020). This study was financed by the budget of the Lavrentyev Institute of Hydrodynamics of the Siberian Branch of the Russian Academy of Sciences within the framework of the State Mission (project FWGG-2021-0003-2.3.1.2.4, state registration number 121121600293-2).

N2 - Abstract: 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.
