SYSTEM FOR SUPPLYING FUEL-AIR MIXTURE TO COMBUSTION CHAMBER Russian patent published in 2007 - IPC F23R3/28 

FIELD: gas turbine engineering.

SUBSTANCE: system comprises means for fuel supply interposed between the first means and second means for air supply in the inner ring space of the Venturi device which is defined by the close axial wall and distant radial wall in the direction of the flow. The means for fuel supply comprise at least one first fuel supply circuit provided with at least one opening for injecting fuel and several second fuel supply circuits. The fuel supply circuits are independent of the first circuits and provided at least one opening for fuel injection. The fuel injection opening of the first fuel supply circuit is made in the close wall of the Venturi device to provide the injection of fuel to the combustion chamber in the direction virtually perpendicular to the direction of air flow from the first means for air supply. The openings for injecting fuel of the second fuel supply circuits are made in the distant wall of the Venturi device for injecting fuel to the combustion chamber in the direction virtually perpendicular to the direction of air flow from the second means for air supply.

EFFECT: enhanced reliability.
