Definitions
- the present invention relates to the field of gas turbine technology. It relates to a combustion chamber for a gas turbine according to the preamble of claim 1.
- Such a combustion chamber is e.g. B. from EP-A1-0 597 138 or US-A-5,373,695 known.
- thermoacoustic vibrations occurring in a combustion chamber are influenced in frequency and amplitude by the most varied geometrical and operating parameters of the combustion chamber, the vibrations to be expected in a new combustion chamber can only be predicted very inadequately. It may therefore be the case that the Helmholtz steamers used on the combustion chamber are not optimally matched to the vibrations actually occurring in the combustion chamber.
- the object is achieved by the entirety of the features of claim 1.
- the essence of the invention is that the Helmholtz steamer is designed such that its damping frequency is adjustable, in particular continuously adjustable. As a result, the damping can be easily adapted to the thermoacoustic behavior of the combustion chamber and optimized accordingly. An exchange of parts or entire dampers is not necessary, so that correspondingly large access options can be dispensed with.
- the adjustability of the Helmholtz steamer eliminates the need to manufacture and keep differently configured dampers or damper parts for different resonance frequencies.
- a preferred embodiment of the invention is characterized in that the damping volume of the Helmholtz damper can be changed continuously. This type of adjustability of the damping frequency can be implemented particularly simply and effectively.
- Damping volume and a variable damping volume is divided and the damping volume is changed by changing the variable damping volume.
- variable damping volume is preferably achieved in that the variable damping volume is limited on one side by a displaceable piston.
- This configuration can be implemented very easily from the mechanical point of view and is reliable in operation and easy to operate.
- a proven type of actuation is characterized in that an adjusting element, in particular in the form of a threaded rod, is arranged on the Helmholtz steamer, by means of which the piston can be displaced. Since the combustion chamber is arranged within a turbine housing, it is particularly advantageous for the actuation of the Helmholtz damper if the adjusting element can be operated through a closable access opening in the turbine housing.
- the adjusting element can easily be designed so that only a small opening is required for its actuation, which does not require any significant changes on the turbine housing.
- the damping effect of the Helmholtz damper is particularly high if, in the case of a combustion chamber which has a plurality of burners on its inlet side and which open into the combustion chamber, the at least one Helmholtz steamer is arranged on the inlet side in the immediate vicinity of the burners. If the combustion chamber is annular and the burners are arranged in concentric rings, the at least one Helmholtz steamer is preferably arranged between the rings.
- FIG. 1 shows a detail in cross section of the inlet side of a gas turbine combustion chamber with two rings of double-cone burners and an adjustable Helmholtz steamer arranged between them according to a preferred exemplary embodiment of the invention
- FIG. 2 shows an enlarged sectional view of the Helmholtz steamer from FIG. 1.
- FIG. 1 shows a section in cross section of the inlet side of the combustion chamber of a gas turbine with two rings of double-cone burners and an adjustable Helmholtz steamer arranged between them, in accordance with a preferred exemplary embodiment of the invention.
- the gas turbine 10 is enclosed by a gas turbine housing 11, within which there is a plenum 12 filled with compressed air.
- the plenum 12 surrounds the combustion chamber 16, which is separated from the plenum 12 by a combustion chamber housing 13.
- the arrangement of the combustion chamber 16 within the gas turbine 10 is essentially the same as that described in the document EP-A1-0 597 138 mentioned at the beginning.
- the combustion chamber 16 is delimited on the inlet side by a front cover 26.
- the combustion chamber 16 is of annular design and is equipped with burners 14, 15, which are designed in a known manner as double-cone burners and are arranged in rings around the axis of the gas turbine, as is disclosed in EP-A1-0 597 138.
- the burners 14, 15 are arranged in corresponding openings in the front cover 26 and open into the combustion chamber 16.
- Helmholtz steamers 17 are provided between the rings with the burners 14, 15.
- the Helmholtz steamers 17 each have a damping volume 20, 21 that is composed of a fixed cylindrical damping volume 20 and a variable cylindrical damping volume 21.
- the damping volume 20, 21 is connected to the combustion chamber 16 via a comparatively narrow connecting channel 18.
- the arrangement of the connecting channel 18 and the damping volume 20, 21 forms a damping resonator, the resonance frequency of which is determined, among other things, by the size of the damping volume 20, 21.
- the fixed damping volume 20 is selected such that the damping frequency which can be achieved thereby is close to the frequency of one of those in the combustion chamber 16. waiting thermoacoustic vibrations, and that with the addition of the variable damping volume 21, the possible range of variation of this frequency is covered. In this way, it is possible to tune the Helmholtz steamers 17 in a gas turbine which is to be put into operation exactly to the occurring, previously not exactly known vibration frequencies and thus to obtain optimal damping with the least possible means. It goes without saying that differently dimensioned Helmholtz steamers 17 can also be used in combination for damping different vibration frequencies.
- variable damping volume 21 can in principle be achieved in different ways.
- the configuration shown in FIGS. 1 and 2 in which the variable damping volume can be changed continuously by means of a piston 22 which is displaceable in volume, is particularly favorable for the adjustability.
- the piston 22 is displaced in a particularly simple and safe manner via an adjusting element 23 in the form of a threaded rod which is rotatably mounted in a threaded hole 25 in the cover 24 and which closes off the variable volume 21 from the outside.
- the piston 22 can also be fixedly connected to the adjusting element 23.
- the setting is made by a thread in the cover 24, in which the adjusting element 23 is guided.
- a slot can be provided on the outer end face of the adjusting element 23, in which the blade of a screwdriver can engage.
- a comparatively small access opening 19 is provided for operating the adjusting element 23 on the turbine housing 11, aligned with the axis of rotation, which comprises a screwed-in, closable connecting piece.
- adjusting element e.g. threaded rod
