COMBUSTION METHOD OF HYDROCARBON FUEL IN GAS TURBINE ENGINE OR PLANT Russian patent published in 2014 - IPC F02M27/04 F23R3/16 

FIELD: engines and pumps.

SUBSTANCE: combustion method of hydrocarbon fuel in a gas turbine engine or plant, which contain a combustion chamber, consists in a hydrocarbon fuel flow and an air flow supplied to its inlet and compressed in a compressor till high pressure. The fuel-air mixture is ignited, and gases obtained during combustion of the mixture are supplied through the turbine and the nozzle to atmosphere. With that, an electric discharge acts at least on some part of compressed air flow downstream of the compressor; the above electric discharge is arranged so that it can provide the specified values of volumetric energy density and corrected intensity of an electric field so that as a result of its action the air forms low-temperature nonequilibrium plasma containing oscillating and electron-excited oxygen molecules in primary and single states. Some part of hydrocarbon fuel flow is mixed with the obtained low-temperature nonequilibrium air plasma and subject to reforming intensified with molecules of excited oxygen. Synthesis gas generated as a result of the reforming process is supplied to the combustion chamber for additional combustion intensification.

EFFECT: invention improves operating efficiency of a combustion chamber at simultaneous reduction of hazardous emissions to atmosphere and provides stable combustion in fuel-and-air mixtures depleted with fuel.
