Definitions

  • the present invention relates to a heat shield element for use in a heat shield, in particular for use in a gas turbine combustor or gas turbine combustor.
  • Heat shields are used, for example, in combustion chambers or flame tubes, which can be part of a kiln, a hot gas duct or a gas turbine and in which a hot medium is generated or led, are used.
  • a thermally highly loaded combustion chamber may be lined with a heat shield for protection against excessive thermal stress.
  • the heat shield typically comprises a number of surface-mounted heat shield elements which shield the wall of the combustion chamber from the hot medium, such as a hot combustion gas, thus counteracting excessive thermal loading of the combustion chamber wall.
  • Such a ceramic heat shield is, for example, in EP 0 558 540 B1 described. It comprises a number of square ceramic heat shield elements which are attached to an axisymmetric support structure of the flame tube. Each heat shield element has a hot medium facing the hot medium, a cold side facing the support wall and four peripheral surface connecting the hot side to the cold side, the two circumferential surfaces of a heat shield element being provided with grooves in the circumferential direction of the support structure. By means of engaging in the grooves spring-like brackets the heat shield elements are fixed in the circumferential direction of the support structure under Spaltbemik.
  • a cooling fluid is supplied to the gaps between the heat shield elements, which flows from the cold side in the direction of the hot side through the column and thus blocks the column against ingress of the hot medium.
  • suitable ceramic heat shield is, for example.
  • holding members with clip portions are used which engage with the grooves of the peripheral surface and clamp the heat shield member in one direction.
  • the holding elements each have a support portion for supporting a heat shield element on a third peripheral surface.
  • This third peripheral surface has, on the hot side, a protrusion protruding beyond the remainder of the peripheral surface, which rests on the support portion of the holding member such that the heat shield member is also secured in the direction perpendicular to the clamping direction.
  • the heat shield elements are arranged such that small gaps remain between them.
  • a combustion chamber lining with heat shield elements is also in EP 1 302 723 A1 described.
  • sealing elements are arranged in the gaps between the heat shield elements.
  • the heat shield elements of this combustion chamber lining have grooves on their circumferential surfaces.
  • a arranged in the gap between two heat shield elements sealing element engages in the grooves of the two limiting the gap peripheral surfaces.
  • the object of the present invention is to provide an improved heat shield element, which is particularly suitable for use in a heat shield.
  • a heat shield on a support structure comprises a number of heat shield elements, which are configured and arranged on the support structure so that they adjoin each other leaving columns.
  • the support structure of the heat shield has a circumferential direction and an axial direction, wherein the heat shield elements in the circumferential direction of the support structure adjacent to each other, leaving a gap, which is referred to as a circumferential gap, and in the axial direction of the support structure, leaving a gap referred to below as the axial gap adjacent to each other.
  • both the circumferential gaps and the axial gaps are sealed by sealing elements, wherein the sealing elements sealing the axial gaps have a different distance to the supporting structure than the sealing elements sealing the circumferential gap.
  • the axial gaps are to be sealed with sealing elements, the grooves could be continued in the axially adjacent circumferential surfaces. In the axial gaps could then be used analogous to the circumferential gaps sealing elements. At the intersections of the axial gaps with the circumferential gaps remain leaky sections back, through which a cooling fluid can flow selectively into the combustion chamber.
  • the arrangement of the sealing elements for the axial gaps and the circumferential gaps at different distances from the support structure makes it possible to arrange the sealing elements overlapping.
  • the intersections between axial and circumferential gaps are more effectively sealed, allowing for a reduction in the cooling fluid requirement.
  • the sealing elements which seal the axial gaps, can be arranged between the supporting structure and the heat shield elements. On a groove in the second peripheral surfaces can then be waived continue.
  • the heat shield comprises a number of element holders, which the heat shield elements on the Fix support structure both in the circumferential direction and in the axial direction.
  • the gap dimensions of the heat shield are of importance for the amount of cooling fluid required for cooling. The wider the gaps, the more cooling fluid is necessary to effectively shut off the gaps against the hot medium present in the combustion chamber.
  • the heat shields are exposed during operation of the combustion chamber in addition to a high thermal load partly mechanical stress due to vibrations. 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. Such displacement, however, leads to changes in the axial gaps and the circumferential gaps between the heat shield elements in axially symmetrical, in particular conical, combustion chambers or flame tubes. As the heat shield elements move on the support structure, the gaps between them may decrease or increase, resulting in non-uniform leakage of the cooling fluid and uneven temperature gradients in the gaps. In order to lock the column taking into account all gap tolerances under all operating conditions, therefore, an increased cooling fluid requirement is given. In particular, considering enlarged gaps increases the need for cooling fluid. In addition, an individual rework is necessary in the absence of axial fixation of the heat protection elements during assembly due to their not exactly defined axial position, which extends the assembly time.
  • the axial fixation By means of the axial fixation, a displacement of the heat shield elements can be effectively suppressed, so that smaller gap tolerances can be assumed when determining the cooling fluid requirement, whereby 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 thus be significantly reduced.
  • the axial fixation also leads to more uniform temperature gradients on the heat shield elements and to more uniform thermal stresses. As a result, under thermal stress of the heat shield elements less or shorter cracks, so the exchange rate of the heat shield elements decreases and the inspection intervals can be extended. Finally, by means of the axial fixation, the assembly time required for adjusting the gap tolerances in new construction and in the maintenance of a heat shield can be shortened.
  • the heat shield comprises first element holder for fixing the heat shield elements in the circumferential direction of the support structure and second element holder for fixing the heat shield elements in the axial direction of the support structure.
  • the second element holders are formed at the same time for holding the sealing elements in the axial gaps. Due to the fact that the second element holders also hold the sealing element, it is possible to use an additional holding element, as in the case of the axial fixation according to the method of FIG DE 41 14 768 A1 described prior art for holding a sealing element would be necessary to be waived.
  • the support structure has peripheral grooves extending in the circumferential direction of the support structure.
  • the second element holders are designed as staples provided with a staple opening and a staple portion facing away from the staple opening, the staples having the staple portion facing away from the staple opening being inserted into a circumferential groove of the support structure such that at least a portion of the staple engages a recess of a heat shield member the circumferential groove protrudes and serves as an axial fixation of the heat shield element.
  • the sealing elements are inserted in the brackets.
  • the clip can also engagement elements have to engage in a loaded in the clamp sealing element.
  • the heat shield elements each comprise a hot side facing away from the support structure, which is suitable for being exposed to a hot medium, a cold side facing the support structure, and a number of circumferential 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 peripheral surface of an adjacent heat shield element in the axial direction of the support structure, leaving an axial gap.
  • the heat shield element has, on two opposite sides, second circumferential surfaces which in the circumferential direction of the support structure each adjoin a corresponding second peripheral surface of an adjacent heat shield element, leaving a circumferential gap.
  • the element holders engage the second peripheral surfaces of the heat shield elements to fix the heat shield elements in the circumferential direction of the support structure, the second peripheral surfaces being provided with securing portions which prevent displacement of the heat shield elements relative to the element holders along the second peripheral surfaces.
  • the element holders which fix the heat shield elements in the circumferential direction, also take over the fixing in the axial direction.
  • the element holders present anyway for fixing the heat shield elements in the circumferential direction of the support structure, no additional element holders are required. Only the security sections must be incorporated into the heat shield elements, which represents only a slight change from the design of the previously used heat shield elements.
  • the second circumferential surfaces have grooves, in which engagement portions of the element holders engage and in which webs are arranged such that they form a stop for the engagement portions of the element holder in the axial direction of the support structure.
  • the webs form the securing portions which prevent displacement of the element holders along the second peripheral surfaces.
  • a heat shield member according to the invention for attachment to a support structure comprises a hot side facing a support structure adapted to be exposed to a hot medium, a cold side facing the support structure, and a number of peripheral surfaces connecting the hot side to the cold side and abutting circumferentially circumferentially the support structure are provided leaving the circumferential gap adjacent to heat shield elements to be attached and having grooves for engagement by engaging portions of element holders holding the heat shield element to the support structure. In each groove, at least one web is arranged, which forms a stop for the engagement portions of the element holder.
  • a heat shield element designed in this way can also be fixed in the axial direction with the element holders that were previously used for fixing in the circumferential direction of the support structure. It is particularly suitable for use in a heat shield according to the second variant of the heat shield according to the invention with axial fixation of the heat shield elements.
  • the at least one web extends in a first embodiment of the heat shield element according to the invention in the direction of the cold side to the hot side only by a part of the groove profile. This will be the insertion of the usual Sealing elements in the groove not significantly disturbed.
  • the at least one web can also extend in the direction from the cold side to the hot side through the entire groove profile.
  • a retaining element with an engaging portion designed to engage in grooves of heat shield elements has at the engagement portion at least one surface element, the surface normal of which extends in engagement with the groove in the extension direction of the groove.
  • the holding element provides an enlarged abutment surface for abutment with the webs arranged in the grooves and can thus ensure a secure axial fixation of the heat shield element.
  • FIG. 1 shows as a first example of the heat shield, a section of an axisymmetric heat shield for an annular combustion chamber of a gas turbine.
  • two ceramic heat shield elements 1, 2 are shown, which are fixed to an axisymmetric support structure 3 and adjoin one another in the axial direction A of the support structure 3.
  • the heat shield elements are arranged such that a small gap remains between two heat shield elements 1, 2. If the heat shield elements abut each other due to the thermal expansion, this could lead to stresses in the heat shield elements 1, 2 and thus to a previous wear or even breakage of a heat shield element 1, 2.
  • the heat shield elements 1, 2 each have a heat-resistant hot side 4 facing the interior of the combustion chamber, which is exposed during operation of the gas turbine to the hot gas in the gas turbine combustion chamber, and one of the support structure 3 facing cold side 5. Between the hot sides 4 and the cold sides 5, the heat shield elements 1, 2 each have four peripheral surfaces 6, 7, with which the heat shield elements 1, 2 adjacent to adjacent heat shield elements 1, 2. Those circumferential surfaces 6 with which the heat shield elements 1, 2 adjoin one another in the circumferential direction of the support structure 3 have grooves 8 into which engagement sections of element holders can engage in order to fix the heat shield elements 1, 2 in the circumferential direction of the support structure 3.
  • An element holder 25, as used in the present example for fixing the heat shield elements 1, 2, is in Fig. 8 shown.
  • the element holder 25 has an engaging portion 26 designed as engagement tab for engaging in the groove 8 of a heat shield element 1, 2 and a fastening tab 27, by means of which the element holder 25 can be attached to the support structure 3, on.
  • this has profile grooves 9 extending in the circumferential direction, in which the attachment lugs 27 of the element holder 25 can be fixed to the support structure 3 by means of screws, for example.
  • a corresponding holder and its attachment in the profile of the support structure is also in the EP 0 558 540 to which reference is made with respect to the further embodiment and the fastening of the element holder.
  • sealing elements 33 for example. Ceramic seals, inserted to seal the circumferential gap between two adjacent in the circumferential direction of the heat shield elements.
  • each heat shield element 1, 2 has at its axial edges, ie the edges between the two peripheral surfaces 7 and the cold side 5 of a heat shield element, first and second recesses 10, 11. In FIG. 1 is to recognize only one recess of the two heat shield elements.
  • the first recess 10 serves both for receiving a part of a clamp 12, which in FIG. 2 is shown enlarged, as well as for receiving a part of an inserted into the bracket 12 and held by this sealing element 13 for sealing the axial gap between the heat shield elements 1, 2.
  • the second recess 11, however, serves only to receive a portion of the sealing element 13.
  • the sealing elements may be formed in particular as preferably ceramic hose elements.
  • the clip 12 which is preferably made of an elastic material, eg. Steel, has a clip opening 14 and a web 15 facing away from the clip opening (see Fig. 2 ). From the web 15, a first clip portion 16 and a second clip portion 17 extend, which together define the clip opening 14. In this case, the first clip portion 16 and the web 15 substantially at an angle of 90 °, while the second bracket portion 17 and the web 15 include an angle which is greater than 90 °.
  • At the end remote from the web 15 of the second clip portion 17 are jagged, projecting in the direction of the first clip portion 16 protrusions 18 are arranged, which are provided for engagement in an inserted into the clip 12 sealing element 13.
  • the tips of the serrated projections 18 are rounded to avoid damaging the sealing element 13.
  • the clamps 12 are inserted with their clamp opening 14 facing away from the end in a formed in the support structure 13 circumferential groove 19 such that the web 15 rests on the groove bottom 20.
  • the second clip portion is thereby pressed by the groove wall 21 in the direction of the first clip portion 16, whereby the clip 12 is held under bias in the groove 19.
  • the serrated projections 18 engage in an inserted into the clamp 12 sealing element 13 (in Fig. 3 not shown), so that it is held by the clamp 12.
  • the clip 12 When the clip 12 is inserted into the circumferential groove 19, the first clip portion 16 protrudes beyond the circumferential groove 19, whereas the second clip portion 17 is completely disposed within the circumferential groove 19. If the heat shield elements 1, 2 are subsequently fastened to the support structure 3, then the part of the first clamp section 16 protruding beyond the circumferential groove 19 engages in the first recess 10 of the heat shield element 1 (see FIG Fig. 1
  • the clip 12 therefore serves at the same time as a holder for the sealing element 13 and as a holding element for axially fixing the heat shield element 1. Since the first recess 10 both the first clip portion 16 and a part has to absorb the sealing element 13, it has a larger dimension in the axial direction A of the support structure than the second recess 11, which has to receive only a part of the sealing element.
  • sealing element 13 has a different distance to the support structure 3 than the sealing elements 33 inserted into the grooves 8 of the heat shield elements 1, 2, all sealing elements can extend to the edge of the corresponding heat shield element or even beyond, without them hinder each other. Thus, in particular, the crossing points of circumferential and axial gaps can be effectively sealed.
  • FIG. 4 A second example of the heat shield is in Fig. 4 shown.
  • the sealing element 22 is not used in the second example by means of a clamp 12 in a circumferential groove 19 of the support structure 3. Instead it lies on the support structure 3.
  • it can also be attached to the support structure 3 by means of suitable fastening elements, such as with the support structure 3 to be screwed or otherwise to be fixed bracket.
  • the heat shield elements 1, 2 have at their axial edges recesses 23 for receiving a portion of the sealing element 22. In contrast to the first example, however, the recesses 23 on the two axial edges of a heat shield element do not differ in their dimensions.
  • FIG. 4a A variation of this example is in Fig. 4a shown. Unlike in Fig. 4 shown example, no recesses 23 for receiving the sealing element 22 are present at the axial edges of the heat shield elements 1, 2. Instead, the support structure in the region of the axial edges of the heat shield elements 1, 2 has a further circumferentially extending groove 23a for receiving a sealing element 22a sealing the gap between the heat shield elements 1, 2.
  • the heat shield elements 1, 2 are fixed only in the circumferential direction of the support structure 3 by the element holders engaging in the groove 8. If the heat shield elements 1, 2 are to be fixed in the axial direction of the support structure 3, this can be achieved in a modification of the second example according to the invention, that in the grooves 8 of the heat shield elements 1, 2 webs 24 are arranged, which is a stop for the in the grooves 8 engaging engagement plates 26 of the element holder 25 and prevent displacement of the heat shield element in the axial direction A of the support structure 3 relative to the element holder 25 and thus also relative to the support structure 3 (see Fig. 5 and Fig. 6 ). In particular, when engage on both sides of the webs 24 engaging tabs 26 of element holders 25 in the groove 8, the heat shield element is secured against axial displacement.
  • the web 24 extends through the entire groove cross-section, whereby a large stop surface 29 is available and the stability of the heat shield element 1, in particular its peripheral surface 6, is increased.
  • a large web 24 requires adjusting the shape of the sealing elements 33 to be inserted into the groove 8.
  • FIG. 7 An alternative embodiment of the bridge is in Fig. 7 shown.
  • the web 28 extends only through a small part of the groove profile 8, so that sufficient space for inserting the sealing element 33 remains in the groove 8.
  • a change in the shape of the inserted into the groove 8 sealing elements 33 is not necessary in this embodiment.
  • the engaging tab 26 of the element holder 25 at its end formed for engaging in the groove 8 has a semicircular bend 31 on.
  • a larger edge portion of the engaging tab 26 is available for the abutment against the abutment surface 29, 30 of the web 24, 28.
  • the engaging tab 26 of the engaging engagement member 25 engages with a small distance to the abutment surfaces 29, 30 of the webs 24, 28 so as not to hinder the thermal expansion of the webs.
  • the distance is, however, significantly smaller than the width of the axial gap between two heat shield elements. If the engaging tabs 26 engage with a small distance to the abutment surfaces 29, 30 in the groove 8, although the heat shield element 1 in the axial direction A of the support structure can move slightly axially, but the distance of this possible axial displacement of the heat shield element 1 is significantly smaller than that Width of the axial gap, so that it does not significantly affect the gap tolerances.
  • the heat shield element should therefore still be regarded as axially fixed even if the engaging tabs 26 engage in the groove 8 at a small distance from the abutment surfaces 29, 30.
  • the heat shield elements shown in the examples, element holders and the support structure shown in the examples can be quickly and inexpensively modified by modifying the previously used heat shield elements (insertion of the recesses 10, 11, 23 and / or webs 24, 28), element holder (changes to the engaging tab 26) or the previously used support structure (introduction of the circumferential groove 19) realize.
