GAS-TURBINE PLANT AND METHOD OF ITS OPERATION Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: gas-turbine plant has compressor 2, first combustion chamber 3, first turbine 4, second combustion chamber 5 and second turbine 6. First combustion chamber 3 is made in form of ring chamber. This chamber 3 operates with burners 11 arranged over its circumference with provision of preliminary mixing. First turbine 4 is designed so that its exhaust gases have temperature level exceeding self-ignition temperature of fuel 13 used in second combustion chamber 5. Second combustion chamber 5 is made in form of ring combustion chamber without burners and with built-in swirlers 14. Blade machines, i.e. compressor 2, first turbine 4 and second turbine 6, are installed on rotor shaft 1 resting on two bearings 9, 15. EFFECT: increased efficiency of plant, enhanced operating conditions. 15 cl, 1 dwg
