Abstract: FIELD: burners. 
     SUBSTANCE: burner is made of well of specified length (up to 650 mm). The fuel flowing through stabilizer of fuel supply enters the fuel supply pipe and then through fuel nozzles to the mixing chamber of the nozzle. The fuel jet impacts on the conical hollow in the working face of the deflector, thus enhancing the spraying of fuel. The compressed steam enters the ring passage defined by the fuel and steam supply pipes. The steam then enters the first (hydraulic) spraing stage of the mixing chamber through the steam nozzles drilled in the swirler radially and tangentially. The mixing chamber is interposed between the hydraulic deflector and exit section of the fuel nozzle. The steam entrains the fuel jet broken down with the deflector and then continues to break it in the second (gas) spraying stage, in the zone around the rod of the hydraulic deflector.
