METHOD FOR RECIRCULATION OF EXHAUST GAS FROM COMBUSTION CHAMBER OF COMBUSTOR OF GAS TURBINE, AND GAS TURBINE FOR IMPLEMENTING SAID METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for recirculation of exhaust gas from a combustion chamber of a combustor of a gas turbine, which has the advantage of flue gas recirculation in general but is less costly and requires a substantially reduced effort compared with known recirculation technology.SOLUTION: A method for recirculation of exhaust gas 18 from a combustion chamber 11; 25, 25', 27, 34 of a combustor 10, 10', 10'' of a gas turbine 22, 30, 31, 32 back to the supply side of the combustor 10, 10', 10'' provides a partial flow 18a of the exhaust gas 18 in the combustion chamber 11; 25, 25', 27, 34 directly extracted from the combustion chamber 11; 25, 25', 27, 34 and internally fed back to an entrance of the combustor 10, 10', 10'' through an internal channel 12 of the combustor 10, 10', 10''.
