GAS TURBINE ENGINE RUNNING ON LEAN FUEL MIX Russian patent published in 2014 - IPC F02C3/22 F23R3/40 

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises compressor, catalytic combustion chamber, turbine, regenerative heat exchanger, burner and valve. Compressor serves to compress working gas, said gas being of combustible component concentration smaller than that of its inflammability. Catalytic combustion chamber is designed to combust compressed air by catalytic reaction with the help of catalyst arranged therein to produce gaseous combustion products. Said products fed from catalytic combustion chamber drive the turbine. Regenerative heat exchanger serves to heat compressed air fed from compressor into said combustion chamber via used gas fed into turbine via used gas channel into regenerative heat exchanger. Burned serves to combust the gas forced from compressor along with fuel for forming the heating gas and feeding heating gas into used gas channel. Valve is designed to control the amount of gas to be fed to the burner.

EFFECT: ruled out loss of power output or discharge system pressure loss, compact design.
