Interrelated heat transfer processes are numerically studied under conditions of chemical reactions and exothermic and endothermic phase transformations at methane gas hydrate ignition in the course of conductive heating. The dependences of the main characteristic of the process – the ignition delay time on the heating surface temperature, the sample heating rate, the activation energy of the fuel vapour oxidation reaction and the pre-exponential multiplier of the fuel vapour oxidation reaction are established. The limiting values of the main parameters of the energy source, under which the ignition conditions are implemented steadily, are revealed. It is shown that as the heater surface temperature increases, the ignition delay times decrease non-linearly. Self-preservation of the gas hydrate leads to an increase in the ignition delay time. The effect of self-preservation depends on the initial temperature of the heater.
