The paper presents the results of experimental and computational studies on the methane self-ignition process in high-temperature air. The computational studies are based on mass and energy balance equations and experimental data. The real temperature T_real, the ignition delay time τ′ and the increment of temperature δ T are assumed as parameters characterizing the process of self-ignition under conditions of superheating of the air. In order to achieve the minimum ignition delay time τ′ (the maximum reaction rate), the maximum of the real temperature T_real and maximum of the increment of the temperature δ T, the air has to be preheated to a temperature of t_air about 850-875 °C.
