Definitions
- the invention relates to a damping device according to the preamble of claim 1.
- Combustion chamber pulsations which form in the form of acoustic waves
- Combustion chamber pulsations are known and tries to suppress it with suitable constructive measures.
- afterburner systems in aircraft engines so-called backwashed perforated panels used as walls, both for Cooling the wall as well as damping the unwanted acoustic Serve waves.
- Such backwashed pinholes are also used in conventional gas turbine combustion chambers, who basically perform the same task in these namely cooling of the combustion chamber wall and targeted suppression of acoustic vibrations developing within the combustion chamber.
- the damping elements usually work on the principle of the so-called Helmholtz resonator.
- Helmholtz resonators are basically volume elements, whose resonance behavior can be set so that they mechanical or acoustic waves with certain frequencies that they pass through, targeted damping.
- the European publication ER-A1-0 974 788 describes a device for targeted Sound insulation within a turbomachine with a combustion chamber into which a Flow channel a compressible medium, preferably air; is fed in the the compressible medium is flammable with the addition of fuel, and a Helmholtz resonator volume, that with the flow channel in the flow direction before entering the combustion chamber is connected.
- the embodiment is characterized in that within of the Helmholtz resonator volume before entering the flow channel, an injection nozzle arrangement is provided by the liquid in the direction of the flow channel at its finest Liquid drops in the form of a liquid / air mixture can be atomized.
- EP-A1-597 138 describes a gas turbine combustion chamber with an annular combustion chamber discloses, in which the combustion chamber entry with a number of in the circumferential direction evenly distributed burners, which is attached to a front panel are. In the area of the burners are flushed out of the feed pipe, resonance volume and damping pipe existing Helmholtz damper arranged.
- the damping tubes are interchangeable designed, for which the walls of the combustion chamber are provided with a manhole.
- the invention is therefore based on the object of a damping device Reduction of the vibration amplitude of acoustic waves for a burner for operating an internal combustion engine, preferably for driving a gas turbine group, which usually provides a mixing area in which an air and Fuel flow mixed into a fuel / air mixture are provided, as well as a combustion chamber, which is in the flow direction of the fuel / air mixture is subordinate to the mixing area in which the fuel / air mixture is flammable to develop such that any within the Burner acoustic vibrations almost completely suppressed should be.
- the damping device according to the invention is intended to offer possibilities offer a subsequent installation in existing internal combustion engines and easy adjustment of the resonance behavior to the respective burner enable.
- a damping device for reducing the vibration amplitude acoustic waves for a burner for operating an internal combustion engine further developed according to the preamble of claim 1 in that the burner provides a conical mixing region the largest diameter adjoins the combustion chamber and the Helmholtz resonator is attached to the tip.
- the idea on which the invention is based is the direct integration of a Helmholtz resonators in the burner itself, so that the inside of the burner resulting acoustic waves through the Helmholtz resonator, which over the Mixing area directly connected to the combustion chamber itself is complete can be swallowed.
- the damping element is preferably in the form of a Helmholtz resonator arranged directly at the top of the conical burner.
- the Helmholtz resonator can either be closed on one side or for the Passage of supply air and / or fuel must be formed.
- a fuel supply line which is particularly useful for the starting phase the burner is provided and is usually referred to as a pilot gas line is attached between the burner and the Helmholtz resonator.
- a pilot gas line is attached between the burner and the Helmholtz resonator.
- the Helmholtz resonator relative to Burner is movable longitudinally. This can be done, for example, via a telescope trained connecting line to the burner or in the simplest case via a screw thread, through which an individual spacing between Helmholtz resonator and burner entry is possible.
- the Helmholtz resonator itself, the volume of the Helmholtz resonators provide changing adjusting elements, by means of which the resonance behavior of the Helmholtz resonator can be individually adjusted can.
- the Helmholtz resonator is preferably located as close as possible to or even at in the burner itself. To avoid any irritation of the flow with regard to the combustion air in the mixing area of the burner, it is advantageous to that the Helmholtz resonator outside a burner hood surrounding the burner is appropriate. Provisions can also be made that the Helmholtz resonator also has an integrated design within the burner housing is attached without affecting the combustion air flow.
- a Helmholtz resonator for damping acoustic vibrations within a burner are not limited to burner types, which provide a mixing area formed in the manner described; burner types with the damping element according to the invention can also be used be equipped with no swirl-generating central body within of the burner.
- FIG. 1 shows a highly schematic cross-sectional representation through a Burner, which is described in detail, for example, in EP 0 321 809 B1 is.
- a conical mixing area 2 Immediately adjacent to the combustion chamber 1 is a conical mixing area 2, but not on its internal structure and mode of operation at this point is discussed for further details on the aforementioned European Reference printed.
- a Helmholtz resonator 4 At the top of the cone-shaped Mixing area 2 is a Helmholtz resonator 4 directly via a feed line 3 provided that over an open volume with the mixing area 2 and the Combustion chamber 1 is connected.
- the inside of the combustion chamber 1 and the Mixing area 2 emerging acoustic waves can be used with the help of a suitable Helmholtz resonators matched to the resonance behavior of the burner 4 can be damped in a targeted manner.
- a reflection of acoustic waves, the burner shape shown in Figure 1 from left to right in the Inside the Helmholtz resonator 4, are damped there and targeted not reflected back inside the burner.
- the Helmholtz resonator 4 has two opposite ones Openings so that this is from a mass flow, for example Air or fuel flow can be enforced.
- the burner can be equipped with a pilot gas supply line 5 preferably arranged between the Helmholtz resonator 4 and the mixing region 2 is.
- FIG. 1 In contrast to the burner shape according to FIG. 1, the one shown in FIG Burner a V-shaped central body 6, which also like that conical mixing area 2 for the targeted mixing of combustion air 8 and fuel serves. Even in the case of the burner according to Figure 2 is immediate in front of the central body 6 via a feed line 3, a Helmholtz resonator 4 for targeted Attenuation of acoustic waves is provided. Optional, also in this case, an additional pilot gas supply line 5 can be provided.
- the embodiment according to FIG. 3 sees a cavity resonator relative to the burner 4 before, the longitudinally displaceable within the feed line 3 opposite the mixing area 2 is displaceable. This way, without much additional A targeted resonance adjustment can be carried out. additionally for longitudinal displaceability, either by means of two tubes sliding into each other or in the simplest case can be realized with the help of a thread, the Helmholtz resonator 4 adjusting elements not shown in detail, through which the resonance volume of the Helmholtz resonator 4 can be changed can.
- the embodiment provides 3 shows the arrangement of the Helmholtz resonator 4 outside the housing 7 before.
- Such an external arrangement of the Helmholtz resonator 4 relative to the housing 7 serves in particular an undisturbed combustion supply air flow within the mixing area 2 within the housing 7, albeit the acoustic damping behavior essentially through the Helmholtz resonator 4 is determined.
