MIXER OF FUEL WITH AIR FOR COMBUSTION CHAMBERS Russian patent published in 2012 - IPC F23D14/62 F23R3/14 F23R3/36 

FIELD: power industry.

SUBSTANCE: mixer of fuel with air, which includes annular casing, central body, inner swirler, distributing chamber, outer swirler, fuel casing and radial casing and radial swirler. Inner swirler is located around central body. Distributing chamber of the supplied low-energy fuel has flat ring formed with internal and external casings forming a gap between them. Fuel inlet and swirler of distributing chamber of the supplied fuel are located in a gap. Outer swirler has inner circumferential end part located around external casing of distributing chamber of the supplied fuel. Casing for high-energy fuel is located at the end inlet part of annular casing outside outer swirler and in circumfenertial direction around annular casing. Fuel casing is connected to outer swirler in flow direction. Radial swirler is meant for air suction inside annular casing from the area outside the annular casing. Radial swirler is located in flow direction after location place in axial direction of fuel casing and inner and outer swirlers. Fuel concentration is controlled by air near the wall of annular casing at the outlet of annular casing.

EFFECT: flexibility with regard to fuel at maintaining high efficiency and reduction of hazardous emissions.
