Definitions

  • the present invention relates to an arrangement of a support structure of a gas turbine and a heat shield on the support structure for protecting the support structure and / or a wall comprising the support structure or connected to the support structure against flowing hot gas, wherein the heat shield comprises a number of attached to the support structure heat shield elements.
  • heat shields are used.
  • thermally highly loaded combustion chambers of gas turbines are lined with a heat shield to protect the combustion chambers against excessive thermal stress.
  • the heat shield typically comprises a number of surface-mounted metallic or ceramic heat shield elements (hereinafter referred to merely as heat shield elements), which are held by a generally metallic support structure formed in the combustion chamber wall.
  • the heat shield elements have a cold side facing the support structure and a hot side facing the hot medium and shield the wall of the combustion chamber and the support structure from the hot medium, such as a hot combustion gas, thereby counteracting excessive thermal loading of the combustion chamber wall and the support structure.
  • the ceramic heat shield elements are fastened by means of metallic element holders to a support structure of the combustion chamber wall, which has grooves for the insertion of specific sections of the element holders.
  • the inserted into grooves of the support structure element holder are usually bolted to the support structure.
  • the element holders include a portion adjacent to the portion for insertion into the grooves Head part which engages in the groove of a hot surface with the cold side connecting peripheral surface of the heat shield element to fix it to the support structure.
  • a heat shield is for example in EP 0 558 540 described.
  • the heat shield elements are arranged side by side under Spaltbemik comprehensive, ie between their peripheral surfaces are gaps in which the hot medium can penetrate.
  • the hot medium can reach the element holders. Since the metallic element holders would scale or melt at the temperatures prevailing in the combustion chamber, they are cooled by means of cooling air which flows through holes in the support structure into the gaps. This cooling air is taken from the compressor end of the gas turbine and is therefore no longer available to the combustion process, which leads to an increase in the NO x emission.
  • the document JP 59 004 824A shows an arrangement of a support structure of a gas turbine and a heat shield on the support structure.
  • Heat shield elements are attached directly to the support structure by means of a positive combination of groove and profile foot.
  • Between the ceramic heat shield elements and the metallic support structure is a porous ceramic layer.
  • An arrangement according to the invention of a support structure of a gas turbine, in particular a metallic support structure, and a heat shield on the support structure for protecting the support structure and / or a wall comprising the support structure or connected to the support structure against a hot medium, eg a hot gas, comprises a number
  • the support structure of fixed heat shield elements which, for example, be made of a ceramic or a metallic material can.
  • the heat shield elements are fixed by means of a positive connection to the support structure.
  • the shape of the cold side of ceramic heat shield elements facing the support structure can be chosen to be relatively free, so that it can be designed such that, together with a corresponding shaping of the support structure, it allows a good positive fit.
  • the heat shield elements each have at least one profile foot with profile surfaces on their cold side facing the support structure, wherein the profile surfaces represent first active surfaces for the form-liquid connection.
  • the support structure has at least one profile groove with profile surfaces which represent second active surfaces for the positive connection and together with the profile surfaces of the profile base, ie together with the first active surfaces, form effective surface pairs for positive locking.
  • the active surfaces of the heat shield elements and / or the at least one profile groove are provided with a friction-reducing coating so that the heat shield elements can be moved more easily along the groove after insertion of the profile foot into the profile groove. This makes it easier to move and thus placing the heat shield elements in the groove in the construction of the heat shield.
  • Teflon is particularly suitable as the material for the friction-reducing coating.
  • heat shield elements in particular ceramic heat shield elements, as mentioned above, are usually cast
  • the shape of the profile foot can be chosen relatively freely. This makes it possible to choose relatively simple shapes for the profile foot and the profile groove. As a result, significant savings can be achieved in the production of heat shields, since not two complex-shaped grooves must be introduced into the support structure, but a wide, simpler shaped groove sufficient.
  • all cooling air holes and all mounting holes for attaching the element holder can be omitted on the support structure.
  • the profile surfaces of the profile groove extend perpendicular to the flow direction of the hot medium, ie perpendicular to the axial direction of the gas turbine.
  • the heat shield elements are then secured against displacement in the axial direction of the gas turbine.
  • the profile surfaces can be arranged on the profile foot in such a way that they extend perpendicular to the flow direction of the hot medium, ie perpendicular to the axial direction of the gas turbine, after fastening to the suitable support structure.
  • the profile foot of the heat shield element can in particular be configured such that circumferential surfaces of the heat shield element, which connect the cold side with a hot side and extend after attachment to the support structure perpendicular to the flow direction of the hot gas, recesses or grooves, which the heat shield element in an actual shield part and divide the profile foot.
  • the actual shield part of the heat shield element can be formed unchanged.
  • each profile groove comprises at least one threading point for introducing profile feet of heat shield elements into the respective profile groove.
  • Fig. 1 shows a ceramic heat shield element of an inventive arrangement in a perspective view.
  • Fig. 2 shows a detail of a support structure of an arrangement according to the invention in a perspective view.
  • Fig. 3 shows the positive connection of a ceramic heat shield element with the support structure in a sectional side view.
  • FIG. 1 shows a ceramic heat shield element of an inventive arrangement for a hot gas leading combustion chamber of a gas turbine in a perspective view.
  • the heat shield element 10 comprises a hot side 12 facing the hot gas in the gas turbine combustor, a cold side 14 facing the support structure holding the heat shield element 10, and circumferential sides or peripheral surfaces 16 connecting the cold side 14 to the hot side 12.
  • Two of the peripheral surfaces, namely the peripheral surfaces 16, extend in installed in the gas turbine combustor state of the heat shield element 10 perpendicular to the axial direction of the gas turbine combustor and thus perpendicular to the flow direction of the hot gas.
  • recesses or grooves 20 are present, which divide the heat shield element 10 in an actual shield member 22 and a profile foot 24.
  • the profile foot 24 is used for fastening the heat shield element 10 in a profile groove 52 of a support structure 50 (see FIG. 2 ).
  • the profile foot 24 has chamfered surfaces 26, the active surfaces for producing a positive connection with the profile groove 52 of the support structure 50 represent.
  • active surfaces 54 are formed, which are complementary to the active surfaces 26 of the profile foot 24 and produce in conjunction with these the positive connection, which holds the ceramic heat shield element in the groove 52.
  • FIG. 3 An inserted into the groove 52 of the support structure 50 ceramic heat shield element 10 is in FIG. 3 in a cut Side view shown.
  • the heat shield element 10 is introduced with its profile foot 24 into the profile groove 52 of the support structure 50.
  • the profiled surfaces 26 of the profiled foot 24 and the profiled surfaces 54 of the profiled groove 52 form active surfaces which hold the heat shield element 10 in the groove 52 by means of positive locking and thereby fix it to the supporting structure 50.
  • the profile edges in comparison to the profile edges 58, 59 of the profile 52 have a greater distance from each other, so that the width of the profile 52 in the Area of the threading point 60 is increased, in fact so much that the profile foot 24 of the heat shield element 10 can be inserted into the profile groove 52.
  • the heat shield element 10 is then displaced to its destination within the profile groove 52.
  • the profile surfaces 26 of the profile foot 24 or the profile surfaces 54 of the profile groove 52 are provided with a sliding friction-reducing coating. As a material for the coating offers Teflon due to its high temperature resistance.
  • both the profile surfaces 54 of the profile groove 52 and the profile surfaces 26 of the profile foot 24 may be provided with the friction-reducing coating.
