Definitions

  • the invention relates to a heat shield element of a heat shield, a heat shield to a support structure, a use of the heat shield for turbine engines and a method of assembling the heat shield element with the features mentioned in the preambles of each independent claims.
  • the heat shields of turbine engines such as gas turbines and turbine engines, such as those used in power-generating power plants and in larger aircraft, have correspondingly large shielded by heat shields surfaces inside their combustion chambers.
  • the shield must be composed of a plurality of individual ceramic heat shield elements spaced apart from one another with sufficient clearance. This gap provides the heat shield elements with sufficient space for thermal expansion.
  • a cooling fluid in the form of cooling air is blown through cooling passages as an effective countermeasure through the gaps in the direction of the combustion chamber.
  • This cooling air is also used to selectively blow the metal brackets, with which the ceramic heat shield elements (CHS, Ceramic Heat Shields) are clamped to the support structure, and thus to cool.
  • cooling air is also injected below the ceramic heat shield elements to allow cooling of the underside.
  • brackets In order to carry out the brackets as simply and integrally as possible, a construction is known in which these brackets on the one hand in the support structure encircling parallel recessed grooves are inserted and clamped on the other hand with trained gripping portions with holder grooves, in which are formed in the side surfaces of the ceramic heat shield elements.
  • the heat shield elements are successively inserted with the holders in the grooves of the support structure, wherein the trailing elements obstruct the previously positioned in their positions.
  • a circular series of heat shield elements can be formed in a combustion chamber of a gas turbine.
  • the last remaining heat shield element can no longer be mounted in this way because the mutually present adjacent heat shield elements block a tangentially directed assembly movement.
  • a last heat shield element is referred to as dummy stone or dummy.
  • solutions are used with screws for attaching the last heat shield element, which allow mounting in the direction of the surface normal of the support structure.
  • a known screw used for this purpose four screws which engage in recesses which are formed in the side surfaces of the heat shield element for this purpose. This solution is often disadvantaged because on the one hand, the four screws require additional cooling and thereby more cooling air consumption and on the other hand, the assembly brings a handling problem with it.
  • the handling of the four screws enforces the use of fixatives such as bonding or adhesive tape, which are not reliable, so that the screws can be lost and must necessarily be found because of high risk of damage. Furthermore, no overhead mounting is possible, so that a considerable amount of time to position a large turbine assembly in the appropriate easy-to-assemble 6 o'clock position of the mounting station. In addition, it may be necessary for two people to install the last heat shield element as the four screws must be inserted into the corresponding four holes in the support structure. Last but not least is to consider that the screws are relatively expensive because of the highly heat-resistant alloy used and must be replaced with new ones at each dismantling because of high safety requirements.
  • EP 1 701 095 A1 and EP 0 558 540 B1 describe by way of example a heat shield as described above with the described advantages and disadvantages.
  • the heat shield elements are often referred to as stones and retaining elements holding them stone holder.

  • a screw connection is arranged within a bore passing through the center of the cladding element and the insulating part.
  • the EP 0 724 116 A2 also discloses a ceramic lining for combustion chambers with at least one heat shield element, which has a continuous central through hole for mounting the heat shield element on a support structure, which is penetrated by a fastening element.
  • the heat shield member includes a ceramic wall plate forming the hot side and an insulation layer forming the cold side.
  • the object of the present invention in view of the above-described disadvantages in the prior art, is to make a heat shield member mountable as a last one of a plurality of heat shield members of a heat shield, thereby having few mounting members and the heat-protective function, as well as the cooling fluid circulation remain.
  • the invention is directed to a heat shield element for a heat shield having a plurality of heat shield elements arranged adjacently to a support structure, the heat shield element having a hot side and a cold side.
  • the heat shield element has a heat shield plate forming the hot side and a carrier plate forming the cold side, wherein the heat shield plate can be mounted on the carrier plate.
  • the heat shield plate For mounting the heat shield plate at least one through hole in the heat shield plate is provided on the support plate, wherein the position of this through hole in the surface of the heat shield plate is provided substantially as a symmetrical position.
  • This one hole is sufficient to press through a screw.

  • the diameter of the through hole 11 is selected such that the assembly tool, for example a screwdriver or an Allen wrench, just passes freely through. Thereby, the diameter of the through hole 11 can be kept as small as possible, whereby less heat can penetrate into the bore of the hot side 9 and cause a heat problem there.
