Definitions

  • the present invention relates to a combustion chamber having 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 tolerances are unfavorably distributed, such as when all heat shield elements are at the lower tolerance band, by moving the heat shield elements in the axial direction, the gaps between adjacent heat shield elements can increase, resulting in an increased penetration of hot gas in the column.
  • the gaps between heat shield elements by means of sealing air, ie by means of compressed air flowing through the gaps in the combustion chamber, shielded against ingress of hot gas.
  • the object of the present invention is to provide a combustion chamber, in particular an axisymmetric gas turbine combustion chamber, with an advantageous heat shield available.
  • the first object is achieved by a combustion chamber according to claim 1.
  • the dependent claims contain advantageous embodiments of the invention.
  • a holding element for holding a heat shield element on a support structure which may be formed in particular of metal, comprises at least one fixing section for fixing the holding element to the support structure, also called a shoe, and at least one holding section, also called a holder head, which engages an engagement groove is formed, which is present in a peripheral surface of a heat shield element.
  • the holding element has a projection which is arranged such that it protrudes when holding a heat shield element in the direction of the held heat shield element, in particular in the direction of the holding element nearest surface of the heat shield element.
  • 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 is designed as a ceramic heat shield element, has a cold side facing the support structure, a hot side to be turned away from the support structure, ie a hot side facing the combustion chamber interior, and peripheral sides connecting the cold side to 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 section of a cold-side material bar. In this material recess, the projection of a holding element according to the invention can engage.
  • the material recess is arranged in the cold-side material bar.
  • the projection present in the holding element can be designed, for example, in the form of a cylindrical projection arranged on the holding section, in the form of a hook arranged on the holding section or as a tip of a V-shaped region of the holding section in the holding section. If a transition section is present between the fixing section and the holding section, the projection can also be arranged in the transition section.
  • the projection may be formed, for example, as a pad-shaped projection or as a bent portion bent so as to protrude toward the heat shield member when a heat shield member is held.
  • the material recess in the cold side material bar may be present either on the groove side of the material bar or on the cold side of the material bar. In particular, it can also extend from the groove side of the material bar to the cold side of the material bar through the entire material bar. As a material recess in the groove side of the material bar, for example, a V-shaped indentation may be present.

  • 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 has the advantage that no additional component is needed. Due to the axial fixation of the heat shield elements occur less large variations in the gap widths. In particular, particularly large gaps between adjacent heat shield elements can be avoided. The blocking air requirement for blocking the column can thus be reduced, which also leads to a reduction of the temperature gradients in the ceramic heat shield elements. As a result, the thermal stresses in the ceramic heat shield element can be reduced, which leads to fewer or shorter cracks compared to conventional heat shields Heat shield leads. Lower replacement rates and longer life of the heat shield element are the result.
  • 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.
