Definitions

  • the present invention relates to a device for damping acoustic vibrations in combustion chambers, and more particularly to a device for damping acoustic vibrations in gas turbines with adjustable resonator frequency.
  • a gas turbine plant comprises in the simplest case a compressor, a combustion chamber and a turbine.
  • the compressor there is a compression of sucked air, which is then admixed with a fuel.
  • the combustion chamber the mixture is combusted, the combustion exhaust gases being supplied to the turbine, from which energy is withdrawn from the combustion exhaust gases and converted into mechanical energy.
  • thermoacoustic oscillations in the combustion chambers of gas turbines - or turbomachines in general - represent a problem in the design and operation of new combustors, combustor parts and burners for such turbomachines.
  • thermoacoustic vibrations can increase. This can lead to an oscillating interaction between thermal and acoustic disturbances, which can cause high loads on the combustion chamber and rising emissions.
  • Such Helmholtz resonators attenuate depending on the cross-sectional area of the connecting tube and the resonator volume in particular the amplitude of oscillations with the Helmholtz frequency. At more deviant frequencies, the effect decreases sharply with increasing frequency difference.
  • thermoacoustic oscillations At e.g. Using different fuels, in the partial load range or when starting the system to shift the frequencies under which increased thermoacoustic oscillations occur. If the damping device remains the same, it then does not work in the most favorable operating point calculated in advance and can no longer optimally damp the occurring thermoacoustic oscillations. The remaining thermoacoustic vibrations lead to a higher pollutant emissions and to a higher noise pollution.
  • the WO 03060381A1 and the DE 100 58 688 A1 each discloses a gas turbine having a combustion chamber and a device having a resonator for damping acoustic vibrations in the combustion chamber, wherein a rear wall of the resonator is positionally variable to set a resonator frequency.
  • thermoacoustic oscillations in combustion chambers and in particular a device for damping thermoacoustic oscillations in gas turbines, in which the resonator frequency can be adjusted by simple means for damping thermoacoustic oscillations.
  • thermoacoustic vibrations according to claim 1 and by a gas turbine according to claim 8.
  • a device for damping thermoacoustic oscillations in combustion chambers comprises at least one resonator. At least a portion of a wall of the resonator is displaceable to set a resonator volume, wherein the movable part of the wall is provided with a thread, so that by a screwing the change in location of the movable part of the wall is effected.
  • the invention offers many advantages.
  • the basic construction of the resonator according to the invention is simple.
  • the cross section does not have to be different from the previously known resonators, so that constructive adaptations for receiving the resonator are not absolutely necessary.
  • the resonator is designed substantially as a Helmholtz resonator. This is advantageous because Helmholtz resonators offer many design possibilities.
  • c is the speed of sound in the medium
  • V is the volume of the resonator chamber
  • L is the length
  • S is the area of the resonator tube between the resonator chamber and the surroundings.
  • the volume V thus influences the resonant frequency of the resonator. Increasing the volume causes a reduction in the resonator frequency and vice versa.
  • the resonator frequency can be adapted to changing conditions.
  • the spatial variability according to the invention of a wall of the resonator influences the resonator volume and thus directly the resonator frequency. An exact adjustment is possible.
  • the mobile part of the wall is in particular longitudinally displaceable.
  • the mobile part of the wall is threaded. Then can be effected by a simple screwing the longitudinal displacement of the movable part of the wall and so the volume of the resonator can be accurately adjusted. Such a screwing is Under certain circumstances also possible during operation, which offers particularly great advantages.
  • the mobile part is formed as part of the rear wall.
  • This can also be designed to be screwable according to the development described above. It is also possible and preferred that essentially the entire rear wall of the resonator is designed to be movable in position and in particular longitudinally movable. At a e.g. essentially cylindrical resonator chamber can be influenced by moving the rear wall, which is opposite to the resonator, the volume of the resonator well very effectively.
  • At least part of a side wall is spatially variable.
  • the movable part of the wall is designed as a kind of piston.
  • the resonator space may be formed as a substantially cylindrical tube, in which from the side opposite the resonator tube, a piston or the like is introduced to change the volume of the resonator. Then a linear motion to control the resonator volume may suffice. Furthermore, there may be a linear relationship between the distance traveled by the wall or the piston and resonator volume.
  • a movement or adjusting device is provided, by means of which the movable part of the wall is hydraulically or electrically movable.
  • the movable part of the wall is controllable by means of the movement device. Then, the mobile part can take a position depending on a predetermined manipulated variable. In other developments, an automatic adjustment of the mobile part takes place. Particularly preferred is also a control device, which causes an automatic adjustment of the movable part of the wall in response to measured resonances, so that within the control range, an effective damping can be ensured.
  • the invention relates to a gas turbine with at least one combustion chamber and at least one damping device for damping acoustic vibrations in at least one combustion chamber, wherein a frequency of the damping device is adjustable.
  • At least a part of a wall of the resonator is movable in order to change a resonator volume and to set a resonator frequency, wherein the movable part of the wall is provided with a thread, so that by a screwing the change in location of the movable part of the wall is effected.
  • the spatially variable part of the wall of the resonator is accessible from outside the housing of the gas turbine.
  • the resonator can be arranged at least partially outside the housing of the gas turbine. It is also possible that the resonator is provided inside the housing, and that the mobile part of the wall is externally connected to e.g. a tool is accessible.
  • Preferred developments are those in which the position of the movable part of the wall can be controlled and / or regulated from the outside.
  • Fig. 1 shows a first embodiment of a device according to the invention in a highly schematic representation.
  • Fig. 2 shows a second embodiment of a device according to the invention in a highly schematic representation.
  • FIG. 1 a first embodiment of a device 1 according to the invention for damping acoustic vibrations in a combustion chamber 2 of a gas turbine 12 is shown.
  • the device 1 is embodied here in the example as a Helmholtz resonator 3.
  • the Helmholtz resonator 3 has a resonator neck 16, via which the Helmholtz resonator 3 is connected to a combustion chamber of a gas turbine, and a resonator chamber 17.
  • the Helmholtz resonator has a resonator volume 5.
  • the resonator 3 is cylindrically symmetrical with a longitudinal or central axis 7 executed.
  • embodiments are also possible which have no such pronounced symmetry.
  • the resonator 17 is surrounded to the sides of the cylindrical side wall 10.
  • a portion 6 of the wall 4 is movably provided to vary the size of the resonator volume and to adjust the resonator frequency.
  • the entire wall 4, which serves as the rear wall 9, movable it is also possible that only a central portion or the like is designed to be movable.
  • the rear wall 9 is displaced along the longitudinal axis 7. If the rear wall is displaced in the direction of the combustion chamber 2, the resonator volume 5 is reduced and the resonator frequency is increased. If, on the other hand, the rear wall is moved out and the resonator volume increases, the resonant frequency of the resonator 3 is reduced.
  • an effective change in the resonant frequency of the resonator is possible, so that the resonator 3 can be adapted to the vibrations to be damped.
  • the rear wall 9 and the inner sides of the side walls 10 may be provided with a thread 8, so that by a screwing in or unscrewing the rear wall 9 is a change in location, to adjust the resonant frequency.
  • the adjustment can be done manually with a suitable tool or by hand after opening the turbine housing 13. This may only occur during standstill of the machine in order to lower the gas turbine to e.g. to adjust a modified fuel composition.
  • the adaptation with a relatively low installation effort is feasible, especially compared to the cost of replacing entire resonators.
  • a controlled adjustment of the rear wall 9 takes place.
  • the adjustment can also be done automatically and also regulated.
  • an electric motor is possible which rotates the rear wall 9 in the thread 8 in order to adjust the resonator volume 5.
  • the use of a hydraulic actuator is possible.
  • the resonator 3 is arranged in the interior 15 of a gas turbine 12.
  • the resonator 5 is partially disposed in the region 15 within the gas turbine and also partially in the region 14 outside of the gas turbine 12.
  • the resonator 3 comprises a first resonance space 3a, which is arranged within the housing 13 of the gas turbine 12, and a second resonance space 3b, which is arranged in the region 14 outside the housing 13.
  • Both resonant cavities 3a and 3b are interconnected by a connecting channel 3c and together form the resonant cavity of the resonator 3.
  • the resonator chamber can also protrude outward with a constant cross section through the housing 13.
  • the rear wall 9 is designed here in the example as a piston 11, which is provided slidably within the resonator.
  • the piston 11 By a movement of the piston 11, the volume 5 b of the resonance chamber 3 b of the resonator 3 is affected, which is part of the resonator volume 5. Therefore, the resonator volume 5 can be adjusted effectively by means of a movement of the piston.
