FUEL NOZZLE Russian patent published in 2017 - IPC F23D11/32 

FIELD: electricity-producing industry.

SUBSTANCE: fuel nozzle includes a housing, a fuel channel with a spray nozzle, internal and external air ducts, fuel and air internal and external swirlers to twist fuel and air flows, two electrodes connected to an electrical voltage source, insulating sleeves between the electrodes. The internal air channel is formed by the inner surfaces of the central metal rod located in the entrance confuser of the internal metal air swirler with a sharp exit edge which, together with the metal film on this sharp edge and at the outlet end of the insulating sleeve in the fuel channel with the swirling fuel flow, are simultaneously one of the electrodes, connected to the potential output of the electrical voltage source. The second electrode connected to the "ground" output of the electrical voltage source is the inner surface of the spray nozzle in the fuel channel, together with the metal housing and the external air swirler.

EFFECT: increased completeness of fuel combustion, reduced level of combustion products toxicity.
