Definitions

  • the present invention relates to a damper arrangement.
  • the damper arrangement is used to damp pressure oscillations that are generated during operation of a gas turbine provided with a lean premixed, low emission combustion system.
  • Gas turbines are known to comprise one or more combustion chambers, wherein a fuel is injected, mixed to an air flow and combusted, to generate high pressure flue gases that are expanded in a turbine.
  • pressure oscillations may be generated that could cause mechanical damages to the combustion chamber and limit the operating regime.
  • combustion chambers are provided with damping devices, such as quarter wave tubes, Helmholtz dampers or acoustic screens, to damp these pressure oscillations.
  • damping devices such as quarter wave tubes, Helmholtz dampers or acoustic screens
  • traditional Helmholtz dampers 1 include a damping volume 2 (i.e. a resonator volume) and an entrance portion or neck 3 to be connected to a combustion chamber 5, wherein combustion occurs and pressure oscillations to be damped may be generated (reference 4 indicates the wall of the combustion chamber 5) .
  • a damping volume 2 i.e. a resonator volume
  • an entrance portion or neck 3 to be connected to a combustion chamber 5, wherein combustion occurs and pressure oscillations to be damped may be generated (reference 4 indicates the wall of the combustion chamber 5) .
  • the resonance frequency (i.e. the damped frequency) of the Helmholtz damper depends on the geometrical features of the damping volume 2 and entrance portion 3 (neck) and must correspond to the frequency of the pressure oscillations generated in the combustion chamber 5.
  • the damping frequency bandwidth of the Helmholtz dampers 1 is very narrow, such that in case one single Helmholtz damper is used, it could not be able to cover the whole frequency bandwidth of the pressure oscillations that are generated in the combustion chamber 5.
  • Helmholtz dampers 1 are connected to the combustion chamber 5.
  • a Helmholtz damper in order to efficiently damp pressure oscillations having a fixed frequency, a Helmholtz damper must be located at the position of the combustion chamber where that pressure oscillations have maximum amplitude.
  • DE102005062284 discloses a combustion chamber with a damper arrangement including several Helmholtz dampers connected in series.
  • the technical aim of the present invention therefore includes providing a damper arrangement addressing the aforementioned problems of the known art.
  • an aspect of the invention is to provide a damper arrangement, which is able to damp pressure oscillations having different frequencies at the same location.
  • Another aspect of the invention is to provide a damper arrangement, which is quite compact and, in other words, requires a limited space, in particular when compared to traditional Helmholtz dampers connected in series.
  • the damper arrangement 10 comprises a first damping volume 11 with a first entrance portion or neck 12 connectable to a chamber 13 wherein pressure oscillations to be damped may be generated.
  • the chamber 13 may be the combustion chamber of a gas turbine.
  • the arrangement 10 has a second damping volume 15 with a second entrance portion or neck 16.
  • the second entrance portion 16 is housed within the first entrance portion 12.
  • first and the second entrance portions 12, 16 are defined by a first and a second tubular part that are preferably coaxial with each other.
  • the mouth 18 of the tubular part defining the second entrance portion 16 is flush with the mouth 19 of the tubular part defining the first entrance portion 12 (i.e. they are aligned and in particular the mouth 18 does not protrudes from the mouth 19).
  • the second damping volume 15 is included (i.e. housed) within the first damping volume 11. Nevertheless in different embodiments it could also be external or partially external to it; for example the wall defining the first damping volume 11 could have a hole through which the second volume 15, or also the first entrance portion 16, passes.
  • first volume 11 and the first entrance portion 12 define a Helmholtz damper and the second volume 15 and the second entrance portion 16 also define a Helmholtz damper (embodiment shown in figure 2 ).
  • first volume 11 and the first entrance portion 12 define a Helmholtz damper and the second volume 15 and the second entrance portion 16 define a quarter wave tube (embodiment shown in figure 3 ).
  • first volume 11 and the first entrance portion 12 may define a quarter wave tube and the second volume 15 and the second entrance portion 16 may also define a quarter wave tube (embodiment not shown).
  • first entrance portion 12 and/or the second entrance portion 16 may be provided with means 20 to enhance viscous dissipation (in order to increase damping efficiency).
  • figure 4 shows an entrance portion 16; it is clear that even if this particular example is described and shown, also different embodiments are possible and the means 20 may be provided at the entrance portion 12 in addition to or instead of the entrance portion 16. Moreover also the entrance portion of a quarter wave tube (in case it is provided) may be provided with the means 20.
  • Figure 5 shows a first embodiment of the means 20 to enhance viscous dissipation being a perforated plate.
  • the means 20 may also be a vortex generator.
  • Figures 6 and 7 show a further embodiment in which the means 20 are arranged to increase the inner surface of the entrance portion 16; in this case the means 20 may define a cross section such as a star shaped cross section (eventually by introducing into the entrance portion 16 a holed cylinder having internal walls with the required shape, as shown in the enclosed figures 6 and 7 ).
  • Figure 8 shows a further example in which the means 20 comprise additional plates housed in the entrance portion 16.
  • means 21 to reduce the flow resistance may also be provided at the entrance portion 16 and/or 12, both in case the damper arrangement comprises Helmholtz dampers and/or quarter wave tubes.
  • These means 21 could comprise rounded inlet and/or outlet of the entrance portions ( figures 9 and 10 ).
  • cooling holes may be provided, to allow cooling air 23 to enter the first and/or second volume 11 and/or 15.
