METHOD OF BURNING FUEL BY MEANS OF INJECTOR WITH TWO-FLOW TANGENTIAL INLET Russian patent published in 2003 - IPC

FIELD: gas-turbine engines. SUBSTANCE: preliminary mixing of fuel with air is ensured by injector provided with spiral swirler with first and second end plates bounding the cylindrical mixing zone. Proposed method includes tangential introduction of first part of air into mixing zone along entire length of this zone, introduction of first part of fuel into air, mixing air and fuel by forming vortex flow around central part at simultaneous motion of vortex flow towards inlet hole of combustion chamber, delivery of first part of air to inlet hole, introduction of second part of air to first part radially; total amount first and second parts of air forms joint flow and second part of air is equal to 85 to 89% of this flow. Subsequent burning of fuel is effected beyond mixing zone. EFFECT: enhanced stability of combustion. 4 cl, 3 dwg
