Definitions

  • the present invention relates to holding elements and heat shield elements for the construction of a heat shield attached to a support structure as well as a combustion chamber with a support structure and a heat shield attached thereto.
  • Heat shields are used, for example, in combustion chambers or flame tubes, which may be part of a kiln, a hot gas duct or a gas turbine and in which a hot medium is generated or guided, are used.
  • thermally highly loaded gas turbine combustion chambers are lined with a heat shield to protect against excessive thermal stress.
  • the heat shield typically comprises a number of heat shield elements arranged on a support structure that cover the wall of the combustion chamber against the hot combustion exhaust gas.
  • Such a heat shield on a support structure is for example in EP 0 558 540 B1 described.
  • square ceramic heat shield members have a hot side facing the hot exhaust gas, a cold side facing the support structure, and four peripheral sides connecting the hot side with the cold side.
  • the heat shield is provided in particular for attachment to the support structure of an axisymmetric combustion chamber.
  • the heat shield members are held by holding members having a fixing portion for fixing to the support structure and a holding portion for engaging in grooves of peripheral sides of the heat shield members.
  • Those peripheral sides of the heat shield elements, in which the grooves are provided for engagement of the engagement portions extend along the axial direction of the axisymmetric combustion chamber. Therefore, two grooved peripheral sides are located at opposite ends of a heat shield element as viewed in the circumferential direction of the combustion chamber.
  • the heat shield elements are fixed in the circumferential direction of the combustion chamber by the engagement of holding elements fixed to the support structure in the grooves of the peripheral sides.
  • a secure fixation in the axial direction of the combustion chamber is not given, as an axial fixation is not provided.
  • the gaps between heat shield elements are blocked by means of barrier air, i. shielded against ingress of hot gas by means of compressed air flowing through the gaps in the combustion chamber. If large gaps, which can occur due to axial displacements, are to be taken into account, this increases the need for blocking air, which is necessary to sufficiently block the large gaps.

  • the projection of the holding element according to the invention makes it possible to engage in a recess provided in the heat shield element, by means of which the heat shield element can be secured against displacement in a direction parallel to the peripheral surface provided with the groove.
  • a corresponding heat shield element which may be formed in particular as a ceramic heat shield element, has a cold-side facing the support structure, a hot side facing away from the support structure, ie a hot side facing the combustion chamber interior, and peripheral sides connecting the cold side with the hot side.
  • an engagement groove is present, which is limited to the cold side of a cold-side material bar to the hot side of a hot-side material bar and the interior of the heat shield element out of a groove bottom.
  • at least one material recess is present in a portion of a material bar or the groove bottom, which is located in a provided for engagement of a holding element portion of the engagement groove. In this material recess, the projection of a holding element according to the invention can engage.

  • the groove 5 is designed so that it only has the groove base 7 required for the insertion of the shoe width. When pulling up the retaining element 150 in the groove 5, this is supported on a narrow region 9 of the groove 5, whereby a holding force holding the retaining element 150 is conveyed. A non-widened part of the holding element 150 can be lifted freely in the groove 5.

  • the shoes of the retaining elements 150 arranged on the other side are not secured, so that they can slide so as not to hinder the thermal expansion of the heat shield element. With this type of fixation, the heat shield elements are fixed quite well in the circumferential direction of the gas turbine combustor 1.
  • a fixation of the heat shield elements in the axial direction of the gas turbine combustion chamber is achieved in that the holding elements have projections which engage in material recesses of the heat shield elements. This will be described below with reference to FIGS. 3 to 11.

If now the gripping tab 458 of the holding element 450 engages in the groove 410 of the heat shield element 400, so the V-shape prevents a displacement of the heat shield element 400 in the axial direction A of the combustion chamber.
  • a heat shield can be realized on the support structure of a combustion chamber, in which the heat shield elements are secured against displacement in the axial direction.
  • the recess may also be present in principle in the groove bottom or in the hot-side material bolt.
  • arranging the recess in the cold-side material bar lends itself to because the engaging tabs of the holding elements engage with a press fit on the cold-side material bar, whereby a close concern of the holding section on the material bar can be realized.
  • the heat shield elements described in the exemplary embodiments can be produced from previously used heat shield elements by subsequently introducing the material recesses.
  • Existing heat shields can therefore be converted into a heat shield according to the invention by introducing the recesses into the heat shield elements and by using holding elements according to the invention. This conversion can be done, for example, during regular maintenance. It is also possible to replace individual heat shield elements only gradually by heat shield elements according to the invention.
  • the solution according to the invention for axially fixing the heat shield elements can also be used if a ceramic mat is arranged on the cold side of the heat shield elements.
  • the inventive solution Compared with alternative solution proposals, which include the provision of a heat shield elements securing against axial displacement bracket, the inventive solution has the advantage that no additional component is needed.
  • the axial securing of the heat shield elements also allows an optimization of the tolerance concept whereby a shortening of the month time in new construction and service is possible because a subsequent adjustment of the gap tolerances can be eliminated by loops or at least less often necessary.
