METHOD AND DEVICE FOR BURNING FUEL Russian patent published in 2003 - IPC

FIELD: devices for burning fuel; gas-turbine engines and power plants. SUBSTANCE: proposed method includes forming two heavily twisted air flows: primary flow in primary combustion chamber and secondary flow in peripheral zone of main combustion chamber, that is peripheral vortex which excites heavily twisted flow revolving in the same direction, that is near-axis vortex. Device proposed for realization of this method includes main combustion chamber with flame tube, secondary air supply unit which are located in one section perpendicularly to central axis of combustion chamber, swirler and combustion product escape passage; device includes also primary combustion chamber with flame tube, fuel supply unit and primary air supply unit, swirler and igniting unit. EFFECT: enhanced stability of process; complete combustion at low positive pressure differential between supplied air and fuel. 8 cl, 3 dwg
