Abstract

AT LEAST ONE HELMHOLTZ DAMPER (30) IS ARRANGED IN A COMBUSTION CHAMBER (16) FOR A GAS TURBINE (10). THE COMBUSTION CHAMBER CONSISTS OF A NUMBER OF BURNERS OR THE FORMER IS EQUIPPED WITH A COMBINATION OF BURNERS (14, 15). THE HELMHOLTZ DAMPER (30) IS DESIGNED ACCORDING TO A RESPECTIVELY DETERMINED DAMPING REQUIREMENT, OR A DAMPING REQUIREMENT ESTABLISHED IN ADVANCE, TO COUNTER THE THERMOACOUSTIC OSCILLATION FREQUENCIES OCCURRING IN THE COMBUSTION CHAMBER AND IS ARRANGED WITHIN THE DISPOSED BURNERS (14, 15) OR IN PLACE OF A FREE, AVAILABLE SPACE WITHIN THE COMBINATION OF BURNERS. (FIG. 2)
