GAS TURBINE ENGINE ANNULAR LOW-EMISSION COMBUSTION CHAMBER Russian patent published in 2014 - IPC F23R3/34 

FIELD: engines and pumps.

SUBSTANCE: proposed combustion chamber comprises housing with ring fire tube including two spaced apart ring shells interconnected by front device at tube upstream part, fuel feed system and at least two glow plugs. Said front device is equipped with burner modules arranged in outer and inner concentric rows. Every said module comprises fuel nozzle and axial air swirler. Additionally, said front device incorporates ring flame stabiliser with fuel-air pipes regularly spaced in circle. Said flame stabiliser is arranged between said concentric rows of modules. Circular air feed slots are arranged between ring flame stabiliser and concentric rows of modules. Fuel feed system has three channels. First channel is connected with outer row, second channel is connected with inner row and third channel is connected with fuel nozzles of flame stabiliser pipes. Glow plugs are arranged above outer row of modules. Air axial swirler swirls airflow in one direction, apart from axial swirlers of modules adjacent to every glow plug that swirl air in opposite direction.

EFFECT: low emission of harmful substances, better ignition, compact design.
