Definitions
- the invention relates to a resonator ring, its production method and a combustion basket.
- the object is achieved by a resonator ring according to claim 1, by a method according to claim 6 and by a combustion basket according to claim 11.
- Crack initiation can be avoided by local reinforcement of a hole geometry of a resonator box of a resonator ring with a Y′-strengthened nickel-based superalloy.
- a ring for the resonator ring can be produced conventionally, but also additively, in particular from a nickel-based wrought alloy, in particular from Hastelloy X or Haynes 282.
- Insert plates for the hole geometry are manufactured from Y'-strengthened nickel-based superalloy for local reinforcement, in particular from In738, Alloy 247 or Re
- the insert plates are in particular cast and also in particular produced from plates by eroding.
- Insertion of the insert plates into the ring, in particular in a form-fitting manner, is preferably effected by welding, in particular with IN625, or preferably by soldering.
- a combustion basket is then produced according to the state of the art, in particular by welding.
- Thicknesses of the insert plates can be made thinner: this means that other bore diameters, a different number of holes and thus savings in cooling air are possible
- Figure 1 is a view of a gas turbine engine with a combustion basket
- FIG. 2 shows a view of a combustion basket with resonator rings according to the prior art
- FIG. 3 shows a resonator ring in detail
- FIG. 4 a resonator ring according to the invention
- Figure 5 an insert plate with holes.
- Figure 1 shows a view of a gas turbine engine 5.
- a combustion chamber 6 is located in a combustion basket 7.
- Figure 2 shows a close-up view of the combustion basket 7 and a resonator ring 11.
- Combustion chamber 6 produces combustion products which are directed downstream through combustor 7 and resonator ring 11 into a transition system. From there hot vapours combustion products downstream to a turbine section and can be used to generate electricity.
- the resonator ring 11 is capable of controlling or absorbing various acoustic frequencies generated by the combustor 6 during operation of the gas turbine engine 5.
- FIG. 3 shows a resonator ring 11 as used in a gas turbine engine 5 in detail.
- the resonator ring 11 has a ring 10, preferably two rings 9, 12 connected to one another, which in turn can also each consist of half rings.
- the rings 9 , 12 for the resonator ring 11 can also be made in one piece, ie they can represent a ring 10 .
- the ring 10 or the rings 9, 12 are preferably designed to be round or oval in cross section relative to the flow direction or adapted to the combustion system.
- the ring 10 or the rings 9, 12 each have a plurality of resonator boxes 21, 22 on their peripheral surface, which are preferably evenly distributed there around the circumference.
- the bases of the resonator boxes 21, 22 are trapezoidal, in particular in the form of isosceles regions 15, 16, which are arranged alternately in the circumferential direction with the base of the trapezium pointing downwards or pointing upwards.
- the areas 15, 16 are distributed around the entire circumference of the ring 10 or of the rings 9, 12 respectively.
- the areas 15, 16 are almost as high as a ring 9, 10.
- Frame 18 and cover 23 for the resonator boxes 21, 22 can also be formed together in one piece.
- resonator ring 11 consisting of ring 10 or rings 9, 12 and resonator boxes 21, 22 should be improved according to the invention and better manufactured.
- a complete recess 24 (FIG. 4) available, which is also trapezoidal.
- Figure 4 is an example of a ring 9 or 12 or 10 according to Figure 3.
- the insert plate 27 is preferably produced by casting.
- the insert plate 27 is placed in the recess 24 and connected to the ring 10, 9, 12, in particular soldered.
- Insert plate 27 and ring 10 or rings 9, 12 can in particular also additionally have a positive connection.
- the holes 31 of the respective insert plates are preferably of different sizes in order to accommodate different frequency ranges. before capturing.
- the holes 31 are preferably evenly distributed within the trapezoidal area 15, 16 of the insert plate 27.
- the resonator boxes 21, 22 are then formed from the surrounding frame 18 and cover 23 to form the resonator boxes 21, 22 in a known manner or in a different manner.
- the materials differ by at least one alloying element more or by at least one alloying element less and/or a proportion of at least one alloying element differs by at least 10%, in particular by at least 20%.
- the material of the insert plates 27 is preferably a Y' hardened nickel-based alloy, in particular such as IN738, Alloy 247 or Rene 80.
- the insert plates 27 and also the holes 31 are preferably produced by eroding cast plates.
- a first insert plate has all holes with a first diameter and a second insert plate has holes with a second diameter, the difference between the holes is at least 10%.
