GAS TURBINE ENGINE COMBUSTION CHAMBER Russian patent published in 2011 - IPC F23R3/34 

FIELD: power engineering.

SUBSTANCE: gas turbine engine combustion chamber comprises body, where flame tube is installed with holes for letting air through and swirler at the inlet, nozzle for fuel supply into combustion zone. In body of combustion chamber there is the second flame tube installed first coaxially, at the inlet of which there is a swirler, besides, combustion chamber is equipped with nozzles and sprayers for supply of fuel into cavity of the second flame tube. In the second flame tube there are holes arranged for letting air through into its cavity. At the same time combustion chamber is equipped with gas collector arranged in body joined with body of combustion chamber. Cavities of combustion chamber and body of gas collector are insulated from each other. Body of gas collector is equipped with nozzles for passage air supplied from behind compressor into heat exchanger through cavity, and combustion chamber is equipped with nozzles for air supply from heat exchanger into cavity of combustion chamber, at the same time gas collector has toroidal volute shape.

EFFECT: increased application in composition of gas turbine engine in gas turbine plants designed to produce electric and/or heat energy.
