Each heat shield element has a hot side facing the hot medium, a cold side facing the support wall and four peripheral surfaces connecting the hot side to the cold side, two peripheral surfaces located on opposite sides of a heat shield element being provided with grooves. To fasten the heat shield elements to the supporting wall, holding elements with clip sections are used, which in the

  • a heat shield according to the invention on a support structure comprises a number of heat shield elements which are designed and arranged on the support structure such that they adjoin one another while leaving gaps.
  • the support structure of the heat shield according to the invention has a circumferential direction and an axial direction, the heat shield elements in the circumferential direction of the support structure leaving a gap, which is referred to below as a circumferential gap, and in the axial direction of the support structure, leaving a gap referred to below as an axial gap adjoin.
  • both the circumferential gaps and the axial gaps are sealed by sealing elements, the sealing elements sealing the axial gaps being at a different distance from the supporting structure than the sealing elements sealing the circumferential gaps.
  • the heat shield according to the invention is based on the following observations and findings:
  • the heat shields used for lining axially symmetrical combustion chambers, such as annular combustion chambers of gas turbines, or flame tubes have heat shield elements which are provided with grooves on two peripheral surfaces. Engagement portions of holding elements engage in the grooves of these peripheral surfaces in order to fix the heat shield elements in the peripheral direction of the support structure. In the axial direction, the heat shield elements are either not fixed or the fixing takes place, as described in DE 41 14 768 AI, by means of support elements instead of by means of engagement sections engaging in grooves. The heat shield elements therefore have no grooves on their circumferential surfaces adjoining one another in the axial direction.
  • sealing elements as described in EP 1 302 723 AI, is therefore only possible between circumferential surfaces which adjoin one another in the circumferential direction, ie only circumferential gaps can be sealed with such seals. Accordingly, only sealing elements have so far been used in the circumferential gap. If the axial gaps are also to be sealed with sealing elements, the grooves could be continued in the circumferential surfaces adjoining one another in the axial direction. Sealing elements could then be inserted into the axial gaps analogously to the circumferential gaps. At the intersection of the axial gaps with the initial gaps, leaky sections remain, through which a cooling fluid can flow selectively into the combustion chamber.
  • the inventive arrangement of the sealing elements for the axial gaps and the peripheral gaps at different distances from the supporting structure makes it possible to arrange the sealing elements overlapping. In this way, the intersections between the axial and circumferential gaps are sealed more effectively, which enables the cooling fluid requirement to be reduced.
  • sealing elements which seal the axial gaps, can be arranged between the support structure and the heat shield elements.
  • a groove in the second peripheral surfaces can then still be dispensed with.
  • the heat shield comprises a number of element holders which fix the heat shield elements to the support structure both in the circumferential direction and in the axial direction.
  • the gap dimensions of the heat shield are also important for the amount of cooling fluid required for cooling. The wider the gaps, the more cooling fluid is required to effectively shut off the gaps against the hot medium in the combustion chamber.
  • the heat shields are sometimes exposed to mechanical loads due to vibrations during operation of the combustion chamber. If the heat shield elements are not fixed in the axial direction of the support structure, they can move axially in particular under such a mechanical load. However, such a displacement leads to changes in the axial gaps and in the peripheral gaps between the heat shield elements in the case of axially symmetrical, in particular conical, combustion chambers or flame tubes.
  • the gaps between them can shrink or enlarge, which leads to a non-uniform outflow of the cooling fluid and to non-uniform temperature gradients in the gaps.
  • considering enlarged gaps increases the need for cooling fluid.
  • individual rework is necessary, which extends the assembly time.
  • the axial fixation By means of the axial fixation, displacement of the heat shield elements can be effectively suppressed, so that smaller gap tolerances can be assumed when determining the cooling fluid requirement, as a result of which the cooling fluid requirement can be set lower. In particular in combination with seals arranged in both axial and circumferential gaps, the need for cooling fluid can be significantly reduced.
  • the axial fixation also leads to more uniform temperature gradients on the heat shield elements and to more uniform thermal stresses. This results in fewer or shorter cracks when the heat shield elements are subjected to thermal stress, which is why the exchange rate of the heat shield elements drops and the inspection intervals can be extended.
  • the axial fixation for the Adjusting the gap tolerances when building a new building and the maintenance required for a heat shield can be shortened.
  • the heat shield comprises first element holders for fixing the heat shield elements in the circumferential direction of the support structure and second element holders for fixing the heat shield elements in the axial direction of the support structure.
  • the second element holders are simultaneously designed to hold the sealing elements in the axial gaps.
  • the fact that the second element holder also holds the sealing element means that an additional holding element, as would be necessary for holding a sealing element in the axial fixation according to the prior art described in DE 41 14 768 A1, can be dispensed with.
  • the support structure has circumferential grooves that extend in the circumferential direction of the support structure.
  • the second element holders are designed as clamps provided with a clamp opening and a clamp section facing away from the clamp opening, the clamps with the clamp section facing away from the clamp opening being inserted into a circumferential groove of the support structure in such a way that at least part of the clamp engages into a recess in a heat shield element the circumferential groove protrudes and thus serves as an axial fixation of the heat shield element.
  • the sealing elements are inserted into the brackets.
  • the clip can also have engagement elements for engagement in a sealing element inserted into the clip.
  • the heat shield elements each comprise a hot side facing away from the support structure, that is suitable for being exposed to a hot medium, one cold side facing the supporting structure and a number of peripheral surfaces connecting the hot side to the cold side.
  • a heat shield element On two opposite sides, a heat shield element has first circumferential surfaces, each of which adjoins a corresponding first circumferential surface of an adjacent heat shield element in the axial direction of the support structure while leaving an axial gap.
  • the heat shield element has second circumferential surfaces on two mutually opposite sides, each of which adjoins a corresponding second circumferential surface of an adjacent heat shield element in the circumferential direction of the support structure, leaving an omnip gap.
  • the element holders engage in the second circumferential surfaces of the heat shield elements, the second circumferential surfaces being equipped with securing sections which prevent the heat shield elements from being displaced relative to the element holders along the second circumferential surfaces.
  • the element holders which fix the heat shield elements in the circumferential direction also take over the fixation in the axial direction.
  • no additional element holders are required. Only the securing sections have to be incorporated into the heat shield elements, which is only a minor change compared to the design of the heat shield elements used previously.
  • the second circumferential surfaces have grooves in which engagement sections of the element holder engage and in which webs are arranged such that they form a stop for the engagement sections of the element holder in the axial direction of the support structure. The webs thus form the securing sections which prevent displacement of the element holders along the second circumferential surfaces.
