Definitions
- the invention relates to a gas turbine with a burner which opens into a combustion chamber.
- the combustion chamber is designed as an annular combustion chamber.
- Combustion systems such as gas turbines, aircraft engines, rocket engines and heating systems can cause thermoacoustically induced combustion vibrations. These arise through an interaction of the combustion flame and the associated heat release with acoustic pressure fluctuations. The position of the flame, the flame front surface or the composition of the mixture can fluctuate due to acoustic excitation, which in turn leads to fluctuations in the heat release. If the phase is constructive, positive feedback and amplification can occur. Such an increased combustion oscillation can lead to considerable noise pollution and damage from vibrations.
- thermoacoustically induced instabilities are significantly influenced by the acoustic properties of the combustion chamber and the boundary conditions at the combustion chamber inlet and outlet as well as at the combustion chamber walls.
- the acoustic properties can be changed by installing Helmholtz resonators.
- WO 93/10401 AI shows a device for suppressing combustion vibrations in a combustion chamber of a gas turbine system.
- a Helmholtz resonator is fluidly connected to a fuel supply line.
- the acoustic properties of the supply line or the overall acoustic system are changed in such a way that combustion vibrations are suppressed.
- this measure is not sufficient in all operating states, since it is also possible to suppress vibration combustion vibrations can occur in the fuel line.
- US-A-6 058 709 suggests introducing fuel at axially different positions in the combustion channel of a burner.
- constructive phase positions in the mixture composition are superimposed by destructive ones with regard to the formation of combustion vibrations, so that overall there are lower fluctuations and thus a reduced tendency to form combustion vibrations.
- This measure is comparatively complex in terms of equipment compared to the purely passive measure of using Helmholtz resonators.
- EP 0 597 138 AI describes a gas turbine combustion chamber which has Helmholtz resonators which have been purged by air in the area of the burners.
- the resonators are arranged alternately on the front side of the combustion chamber between the burners. These resonators absorb vibration energy from combustion vibrations occurring in the combustion chamber and the combustion vibrations are thereby damped.
- the object of the invention is to provide a gas turbine with a particularly low tendency to form combustion vibrations. According to the invention, this object is achieved by specifying a gas turbine with a combustion chamber and a burner opening into the combustion chamber at a burner mouth, the burner mouth being surrounded in a ring by a Helmholtz resonator.
- Resonators around the flame can be directly intensively impacted on the location of the highest heat release. This improved contact with the main source of combustion vibrations also increases the effect of the resonator.
- the Helmholtz resonator preferably has a resonator volume and opens into the combustion chamber at a resonator mouth, the resonator mouth being continued with a tube into the resonator volume.
- the resonator mouth is further preferably formed by a plurality of openings, each of which is continued into the resonator volume via a tube.
- the tubes thus protrude into the resonator volume.
- the length of the holes is now significantly increased. This is achieved by designing the bores as tubes that protrude into the volume.
- the internal volume of the resonator is hardly changed.
- the external dimensions of the resonator can thus be kept small.
- the tubes can be wound so that they are at a sufficient distance from the walls.
- the damping device can be adjusted to any frequency that occurs in the combustion system.
- the external dimensions of the resonator and thus of the burner insert and the total open cross-sectional area do not have to be changed.
- the main advantage in order to attenuate low frequencies, the projecting tubes can be used to dispense with an increase in volume of the resonator.
- the tube or the tubes are curved or twisted, so that the tube length is increased without being less than a minimum distance from the resonator wall.
- the resonator volume is preferably adjustable, for example by a piston-like displacement of a resonator wall.
- the acoustic properties in particular the impedance, can be adjusted and set.
- the combustion chamber is designed as an annular combustion chamber.
- combustion vibrations can lead to very disturbing and damaging combustion vibrations due to a comparatively large combustion chamber volume and burners coupled therein.
- the acoustic properties of such a combustion chamber can hardly be calculated.
- the Helmholtz resonator is preferably integrated in a burner insert, the burner being connected to the combustion chamber via the burner insert.
- the burner insert can be a separate component that is screwed to the combustion chamber wall and into which the actual burner is then inserted. However, it can also be connected to the burner, so that, for example, the burner insert forms a flange on the burner with which the burner is connected to the combustion chamber wall.
- the integration of the resonator in the burner insert means that no structural measures are required on the combustion chamber wall and the resonator can be easily removed if necessary.
- the Helmholtz resonator is preferably designed to allow air to flow through it. In this way, the impedance of the resonator can be changed and adapted in a simple manner. In addition, cooling of the resonator and, if the resonator is integrated in the burner insert, cooling of the entire burner insert is also achieved.
- Figure 1 a gas turbine
- Figure 2 a burner arranged on a combustion chamber wall
- a gas turbine 51 is shown in FIG.
- the gas turbine 51 has a compressor 53, an annular combustion chamber 55 and a turbine part 57.
- Air 58 from the environment is fed to the compressor 53 and compressed there to combustion air 9.
- the combustion air 9 is then fed to the annular combustion chamber 55. It is burned there with fuel 11 to a hot gas 59 via gas turbine burner 1.
- the hot gas 59 drives the turbine part 57.
- combustion vibrations can form come that can significantly affect the operation of the gas turbine 51.
- Helmholtz resonators can be used to dampen such combustion vibrations, a particularly effective design being described below:
- FIG. 2 shows a gas turbine burner 1, which is connected to a combustion chamber wall 56 of a combustion chamber 55 via a burner insert 2 and opens into the combustion chamber 55 at a burner mouth 4.
- a burner duct 3 of the gas turbine burner 1 surrounds a central duct 41 as an annular duct 30.
- the annular duct 30 is designed as a premixing duct in which fuel 11 and combustion air 9 are mixed intensively before combustion. This is known as premix combustion.
- the fuel 11 is introduced into the ring channel 30 via swirl vanes 13 of hollow design.
- the central channel 41 opens into the combustion zone 27 together with a central fuel lance 45 which supplies fuel 47, in particular oil, via a swirl nozzle 47.
- fuel 11 and combustion air 9 are only mixed in the combustion zone 27 and one speaks of a diffusion combustion.
- fuel 11, in particular natural gas can also be added into the central channel 41 upstream of the combustion zone 27 via a fuel inlet 43.
- a Helmholtz resonator 19 is integrated in the burner insert 2 and has a resonator volume 23 and opens into the combustion chamber 55 via a resonator mouth 21 consisting of bores.
- a tube 61 adjoins each of the bores into the resonator volume 23 and is shaped to be twisted.
- the Helmholtz resonator 19 surrounds the burner mouth 4 in a ring.
- the tubes 61 allow a comparatively small size for the resonator 19, so that it can be integrated into the burner insert 2. Air is introduced into the resonator 19 via air inlets 63, whereby the impedance of the resonator 19 can be adjusted on the one hand, and can also be cooled on the other.
