Definitions

  • the invention relates to a heat shield element, in particular for lining a combustion chamber wall with integrated cooling air ducts according to the preamble of claim 1.
  • the object of the invention is to provide a heat shield element of the type mentioned, which allows the lowest possible consumption of cooling air at an advantageous cooling and the same time as simple and inexpensive to manufacture and assemble.
  • the generic heat shield element is intended for use in a combustion chamber, which is in particular the combustion chamber in a gas turbine.
  • the heat shield element initially comprises a wall which has a hot side which can be acted upon by a hot medium and a cold side which is opposite to the hot side.
  • Surrounding the wall is an edge which extends from the hot side to beyond the plane of the cold side.
  • the edge has an inner side adjacent to the cold side and an opposite side to the hot side adjoining outside.
  • a fastening device Arranged substantially in the middle of the wall is a fastening device which extends from the wall away from the hot side and out past the cold side.
  • the fastening device has a passage opening, so that a fastening means can be attached to the fastening device when passed through the passage opening.
  • a plurality of cooling channels are introduced into the heat shield element according to the invention, which pass through the wall of the heat shield element from the fastening device to the edge. It is provided that in the fastening device cooling air inlets are arranged in the cooling air ducts, wherein cooling air outlets are arranged from the cooling air ducts in the region of the edge.
  • first cooling air outlets are arranged on the outside of the edge, so that an outlet of the cooling air takes place in the gap between adjacent heat shield elements.
  • the coolant flows through all parts of the heat shield element in the order fastener, wall, edge and thus cools in all areas before the cooling air is discharged into the gap between two heat shield elements in the combustion chamber at the edge and locks the gap against indentation of Hot gas from the combustion chamber.
  • third cooling air outlets are arranged on the hot side of the wall in the region of the edge, so that an exit of the cooling air takes place immediately adjacent to the gap into the combustion chamber. This allows for additional film cooling of the heat shield element.
  • the hot side of the heat shield element can thus be kept homogeneous at a constant temperature, since a protective Forming boundary layer between the hot combustion chamber gases and the heat shield element.
  • the return of the cooling air flow leads to the underside of the heat shield elements that now the heated air flow is dissipate, which in turn causes a consequential problem towards the cooling air.
  • the arrangement according to the invention of the first and / or third cooling air outlets at the edge of the heat shield element with an outflow of the heated cooling air into the gap and / or into the combustion chamber removes the heat from the heat shield element, without the heat transferring the interior, i. the cold side, reaches the heat shield element. With the same amount of air so a further reduction of the temperature in the interior of the heat shield element is reached (or the same temperature with less cooling air). A reduction in temperature has a positive effect on other components of the heat shield element, which are less thermally stressed.
  • cooling air inlets are provided on an outer side of the fastening device.
  • the fastening device is centrally located on the wall of the heat shield element and is therefore the ideal location for feeding the cooling air into the cooling air channels.
  • second cooling air outlets are provided on the inside of the fastening device.
  • the cooling function can be extended to the fastening means of the heat shield element.
  • internally cooled mounting screws are used for the attachment of heat shield elements.
  • fourth cooling air outlets are provided on the hot side in the region of the fastening device. This allows additional film cooling of the heat shield element in the region of the attachment, so that a protective boundary layer is formed between the hot combustion chamber gases and the attachment means.
  • the passage opening of the fastening device has a contact surface for a screw head, so that the screw is sunk in the installed state in the heat shield element, so that it is not acted upon at exposed point with hot gas.
  • the heat shield element is substantially metallic, i. it consists essentially of a metal or a metal alloy, e.g. High temperature resistant alloys based on iron, chromium, nickel or cobalt. Compared to ceramics metals have a lower brittleness and a more favorable thermal and thermal conductivity.
  • the heat shield element is used to protect and cool a hot gas carrying combustor, preferably an annular combustor of a gas turbine having a support structure to which such heat shield elements are attached.
  • the heat shield element is preferably arranged with a fastening means, for example a screw, on the support structure.
  • a heat shield element having a wall which has a hot side which can be acted upon by a hot medium and a cold side which is opposite to the hot side, and an edge which adjoins the wall and extends beyond the plane of the cold side with an inner edge. and an outer side and a fastening device arranged substantially in the middle of the cold side of the wall, which extends substantially perpendicularly away from the wall, with cooling channels being arranged in the fastening device, wall and edge, which extend over at least two of the three a metallic material having a suitable local distribution in powder form is remelted in layers on a substrate by means of laser radiation, so that in each case a further solid layer is formed upon solidification of the molten powder.
  • a three-dimensional CAD model is created in a first step, which is divided into layers in a second step.
  • the actual production of the heat shield element is carried out in the following steps, wherein in the third step, a powder layer is applied to a substrate, in the fourth step, the applied powder is exposed or remelted by a laser and in the fifth step, the pad to the layer thickness of the second step is lowered. The third to fifth steps are repeated until the heat shield element is completely made.
  • heat shield elements with comparatively small numbers of pieces are to be produced sensibly using this method. Also, in the case of service can respond quickly to the needs, so that downtime of the equipment can be reduced.
  • the FIG. 1 shows a gas turbine 21, the 21 is shown partially cut longitudinally.
  • the gas turbine 21 has a compressor, an annular combustion chamber (20) with a plurality of burners for a liquid or gaseous fuel, a turbine for driving the compressor and a in FIG. 1 Not shown generator.
  • the combustion chamber wall is lined with heat shield elements 1, or the heat shield elements 1 are mounted on a support structure 22 on the combustion chamber wall.
  • air is sucked in from the environment.
  • the compressor the air compressed and thereby partially heated.
  • a small portion of the air is removed from the compressor and supplied as a coolant to the heat shield elements 1, the greater part of the air is supplied to the burners for combustion.
  • the combustor 20 the greater part of the air from the compressor is contacted with the liquid or gaseous fuel and burned. This creates a hot gas that drives the gas turbine 21.
  • a relaxation and cooling of the hot gas takes place.
  • the heat shield element 30 has a wall 2, which 2 has a hot side 3 (in FIG FIG. 2 on the opposite side) and one of the hot side 3 opposite cold side 4, and one adjacent to the wall 2, circumferential, extending beyond the plane of the cold side 4 also out edge 5 with an inner 6 and an outer side 7.

  • cooling air inlets 10 are provided on an outer side 11 of the fastening device 8 and corresponding first cooling air outlets 12 on the outer side 7 of the edge 5.
  • FIG. 4 is an embodiment of the heat shield element 1 from Fig.1 1, which further comprises second cooling air outlets 13.
