FIELD: engines.
SUBSTANCE: present invention relates to apparatuses with direct injection of liquid hydrocarbon fuel in a droplet state or gaseous hydrocarbon fuel into a combustion chamber of a gas turbine engine and preparation of a fuel-air mixture for combustion in the combustion area in the presence of air. A dual-fuel air-fuel nozzle containing a body of a swirler including a vane swirler, a mixing sleeve, the nozzle body containing an internal channel, a throttle washer, sealing rings, a splined nut. The nozzle body has two fuel supply channels. A gas distribution sleeve is installed in the inner part of the nozzle body, into the center whereof an elongated mesh filter and a centrifugal liquid fuel sprayer are installed. A jet gas sprayer is installed between the nozzle body and the gas distribution sleeve.
EFFECT: proposed invention increases operational capabilities of a gas turbine engine and can be used in aviation, power engineering and the gas industry.
