Definitions

  • the present invention relates to a device for damping acoustic vibrations in one Combustion chamber and a combustion chamber arrangement, in particular a gas or steam turbine holding the device includes.
  • the main field of application of the present invention lies in the field of industrial gas turbines.
  • the increasing awareness of environmental protection and Environmental compatibility requires compliance if possible lower pollutant emissions.
  • thermoacoustic vibrations affect not only the combustion quality negative, but can also affect the life of highly stressed components reduce drastically.
  • a Helmholtz resonator behaves acoustically like an infinitely large opening, ie it prevents the formation of a standing wave at this frequency.
  • thermoacoustic Vibrations with the help of a Helmholtz resonator also for damping the vibrations in combustion chambers of Gas or steam turbines already in use.
  • the problem occurs in gas or steam turbines on that the frequency to be attenuated is not through an intermittent combustion is determined, but by meeting the Rayleigh criterion in the Combustion chamber and the acoustic response of the surrounding Systems from inflow, burner, combustion chamber and acoustic Completion condition.
  • the frequency to be damped can therefore be these systems with those currently available computational tools not with the required Determine accuracy in advance.
  • this is the Prerequisite for the exact dimensioning of the resonance volume take into account when building the gas turbine can.
  • the acoustic behavior of the system and thus the frequencies of the attenuated Vibrations when the operating point changes change decisively, so that under certain circumstances additional Resonators tuned to other frequencies are used.
  • Such an arrangement with several Helmholtz resonators is for example from DE 33 24 805 A1 known.
  • the publication describes a facility to avoid pressure fluctuations in combustion chambers, where several Helmholtz resonators with different Resonance volume along the gas pipeline path to Burners are arranged. Because of the different Resonance volumes can be vibrated with this system attenuate different frequencies.
  • the optimal one Dimensioning of the individual Helmholtz resonators again requires that Knowledge of those that occur during the operation of the system Frequencies that are not yet in the construction of the system can be specified exactly.
  • the arrangement several Helmholtz resonators because of that required additional space requirements unfavorable.
  • DE 196 40 980 A1 describes another known one Device for damping thermoacoustic Vibrations in a combustion chamber.
  • this device is the side wall of the resonance volume of the Helmholtz resonator designed as a mechanical spring. On the wall vibrating due to the spring effect the end face of the resonance volume is an additional one mechanical mass attached. With this arrangement the virtual volume of the Helmholtz resonator is influenced and achieved greater damper performance. By changing the mechanical mass on the resonator can subsequently fine-tune the resonance frequency be performed. However, this also requires a subsequent intervention in the structure of the Gas turbine plant.
  • the present invention is based on the object a device for damping thermoacoustic Vibrations as well as a combustion chamber arrangement specify this device which is a continuous Adaptation to the frequencies of the vibrations to be damped even under high pressure conditions, like them for example in gas turbines.
  • the device consists of a Helmholtz resonator together with a connecting channel that with the combustion chamber, for example the combustion chamber one Gas turbine, is connected.
  • Dampers are in the present Device by feeding or draining a Fluids changeable in volume via a feed line Hollow body provided either inside the Helmholtz resonator is arranged or so on this borders that the resonance volume of the Helmholtz resonator with a change in the volume of the hollow body changed.
  • Hollow body in the Helmholtz resonator is thus reduced in size the resonance volume when the hollow body over the Lead inflated, for example, with a gas becomes.
  • the resonance volume increases of the Helmholtz resonator when out of the hollow body a certain amount of the gas is released.
  • the Changing the resonance volume causes in known Way a change in resonance frequency.
  • the resonance frequency of the Helmholtz resonators at any time by simply inflating them or draining the hollow body to the in the chamber volume occurring thermoacoustic oscillation frequencies be adjusted.
  • a precise knowledge of the operation frequencies occurring when building the corresponding System is therefore no longer required.
  • the Vibrations can be customized across a wide range adjustable frequencies can be damped. In practical terms Use can be done by changing the Resonance volume at all times during operation the system is possible, the resonance frequency of the built-in resonators suitable for the respective operating point to adjust.
  • a particular advantage results from the fact that the resonance volume of the Helmholtz resonator, which in usually within the pressure casing of the gas turbine is arranged, can be changed without this moving parts through the wall of the pressure vessel must be passed through.
  • the supply line to Hollow body can be designed as a rigid tube and therefore easily with high tightness through the pressure housing be led through to the outside.
  • the Helmholtz resonator has a position-changeable device Wall on which the hollow body adjoins.
  • the position-changeable wall is over a Spring mechanism pressed against the hollow body.
  • the position-changeable wall against the spring force pressed inwards and in this way reduces that Resonance volume of the Helmholtz resonator.
  • the resonance volume by shifting the Wall due to the acting in the direction of the hollow body Spring force.
  • the Helmholtz resonator can do this be in the form of a bellows like this known from DE 196 40 980 A1 is.
  • DE 196 40 980 A1 is.
  • the volume-changeable hollow body is preferred as an inflatable temperature-resistant balloon or designed as an inflatable metallic bellows.
  • the supply line to the hollow body can be flexible or rigid be carried out.
  • the gas supply to the hollow body or the gas release from the Hollow body made automatically by a controller, provided outside of the pressure housing on the supply line is.
  • This control changes the resonance volume of the Helmholtz resonator as a function of that in the Combustion chamber frequency of the thermoacoustic Vibrations with the highest amplitude, in which he Blows or releases gas into the hollow body.
  • the respective vibration amplitudes and vibration frequencies with an appropriate sensor, as known to those skilled in the art.
  • the controller controls the resonance volume or the volume of the hollow body by feeding or draining of compressor air that it exits from the compressor Receives gas turbine. This way you can at any time during optimal vibration damping during operation of the gas turbine can be achieved because the controller's resonance volume at any time exactly to the respective occurring Can adjust frequencies.
  • Figure 1 shows the basic structure of a Helmholtz resonator 4 with the resonance volume 3 and one Connection channel 2, as it is from the prior art is known. Details on this were given in the introduction to the description already set out.
  • FIG. 2 A first embodiment for an inventive Device on a combustion chamber 1 a Gas turbine is shown in Figure 2.
  • the tunable Helmholtz resonator 4 can be seen, the via a connecting channel 2 with the combustion chamber 1st connected is.
  • a hollow body 6 Inside the Helmholtz resonator 4 a hollow body 6 is arranged, the volume of which by feeding or draining gas via a feed line 5 changeable is.
  • the hollow body 6 is in this example from a metallic bellows that is exposed to air 10 inflated from the compressor outlet of the gas turbine or is released by venting this air.
  • the so-called resonance volume 3 enlarged from a central position or reduced, as indicated by the arrow in the figure is.
  • the control of inflation or deflation the bellows 6 takes place via a corresponding Regulator 7, the volume depending on each damping thermoacoustic oscillation frequencies sets.
  • the configuration of the hollow body 6 as a metallic bellows is particularly suitable for use suitable under high temperatures.
  • the supply line 5 to the bellows 6 takes place through the Pressure housing 8 of the gas turbine.
  • This implementation can be sealed well by the pressure housing 8, since it contains no moving parts. With the present device, it is therefore possible to adjust the resonance volume 3 of the Helmholtz resonator 4, the inside of the pressure housing 8 is mounted from the outside to change the pressure housing without the risk of To increase leakage of the pressure housing 8.
  • the resonance volume 3 is tuned via the automatic controller 7, which, as already mentioned, depending on the frequency of the highest vibration amplitude in the combustion chamber the bellows 6 enlarged or downsized. Since the location of this amplitude on the Frequency axis when operating the burner only within of a relatively narrow band is not special fast regulation required to get an optimal To achieve adjustment.
  • Figure 3 finally shows another example for a possible embodiment of the invention Contraption.
  • the hollow body is 6 not arranged within the Helmholtz resonator 4, but borders on a position-changeable wall 11 of this resonator 4.
  • the principle of operation is that The same as already explained in connection with Figure 2.
  • the Helmholtz resonator 4 as well as the hollow body 6 - at least partially - designed as a bellows, one End face of the Helmholtz resonator 4 to an end face of the hollow body 6 adjoins.
  • the opposite End face of the hollow body 6 is on a corresponding Anchor 9 fixed in the pressure housing 8.
  • the resonance volume 3 is reduced.
  • Spring mechanism the position-changeable wall 11 of the Helmholtz resonator 4 against the hollow body 6 presses.
  • This spring mechanism can, for example through an elastic design of the wall material of the bellows can be reached. Alternatively, you can do this a spring inside the Helmholtz resonator 4 be provided.
