GAS-TURBINE UNIT AND UNIT WITH INJECTOR VANES (VERSIONS) Russian patent published in 2014 - IPC F02C3/14 F23R3/30 

FIELD: machine building.

SUBSTANCE: gas-turbine unit contains the compressor designed with a possibility of intake and compression of working fluid medium, the combustion chamber, turbine. The combustion chamber is designed with a possibility of intake of compressed working fluid medium from the compressor and fuel and with the possibility of burning of mixture of compressed working fluid medium and fuel with formation of exhaust gas. The turbine has the first section and second section and is designed with a possibility of intake of exhaust gas from the combustion chamber and its utilizing for rotating the shaft. Between the first and second sections of the turbine the ring-type combustion device for secondary mixing is located, which contains an injector vane for preliminary mixing, designed with a possibility of mixing of air and fuel with creation of air - fuel mixture and with a possibility of adding of this mixture into exhaust gas, supplied from the first section of the turbine.

EFFECT: invention is aimed at increase of efficiency of the unit at the expense of additional preheating and preliminary mixing of fuel and air.
