Natural gas is a highly efficient energy carrier and a valuable chemical raw material. However, gas reserves are not unlimited. Therefore, there is a need to create technologies to reduce natural gas consumption and increase the productivity of its use. For this, it was proposed to use the directed action of an artificially created low-temperature plasma with an ordered movement of "slow" electrons in the presence of a heterogeneous catalyst and to determine the optimal conditions for these processes. The use of the electron-catalytic method in the processes of combustion allows spending a significantly smaller amount of energy on the process of initiating the primary endothermic stages due to the use of the energy of "slow" electrons, the formation of which is primarily influenced by the non-equilibrium plasma. The theoretical foundations of the process of electrocatalytic intensification combustion of gaseous fuel are considered, namely the influence of elastic and non-elastic collisions, ionization, temperature inhomogeneity between the gas flow and the low-temperature plasma flow, resonance of molecular vibration frequencies and electric discharge. The dependences of the temperature change of heated water on time at different voltages of the electric discharge, the coefficient of excess air and the composition of the catalyst during the electrocatalytic combustion of gaseous fuel are given.
