This invention relates to power engineering industry and engine-building and is designed for intensification of chemical processes in the combustible mixture using pulsed periodic nanosecond high-voltage discharge in internal combustion engines of any kind, including (but not limited to) afterburners, combustors of detonation engines, jet engines and gas turbine engines, in power burners and reformers. For reduction of combustible mixtures ignition temperature, increase of intensity of chemical reactions in combustion and reforming processes and material reduction of release of harmful substances into the atmosphere combustible mixture in the combustion chamber is excited by means of pulsed periodic nanosecond high-voltage discharge, at that discharge amplitude is set so as to provide maximization of the discharge energy deposition in electronic degrees of freedom and gas dissociation and to prevent plasma electrons transfer into the whistler mode at the basic stage of discharge, besides, high-voltage pulse leading edge rise time limited by the constraint allowing to attain uniformity of filling the discharge gap with plasma and effectiveness of pulse energy transfer to plasma, high-voltage pulse duration being limited by the constraint providing attainment of strong non-equilibrium character of pulse discharge plasma and reduction of the discharge gap resistance, its better interface with the generator and effective electric energy deposition into plasma. |
