Definitions

  • the invention relates to a combustion chamber, in particular for gas turbines, with a hollow cylindrical housing, the inner wall of which has a lining composed of individual ceramic elements, and a method for producing or assembling this lining.
  • heat-resistant metallic materials are usually used, which are also used in special arrangements and are optionally provided with thin ceramic layers.
  • linings of flame tubes with thick ceramic materials are also used. Problems can arise when lining concave surfaces with thick wall elements from the inside of the flame tube if the double gap width between adjacent elements is smaller than the difference between the outer and the inner chord length of the elements. This problem is explained using the example of a cylindrical flame tube with the same wall elements in FIG. 1.
  • a fireproof lining for combustion chambers of gas turbine systems which consists of individual stones, which are attached almost completely to a support structure while leaving cooling fluid gaps with metal retaining clips.
  • the stones have, at least on the sides held by metal brackets, bevelled flanks towards the support structure, which are at least partially covered by the also bevelled holding clips and thus press the stones against the support structure.
  • the hot side of the holding clamps which is particularly thermally stressed in this design, is cooled via cooling fluid openings in the supporting structure.
  • This first group of known linings has in common that they consist of individual elements which, using additional holding means on the outer support structure, the gaps between the individual elements being dimensioned such that the leakage air escaping sufficiently cools the metallic holding elements in the gaps. This leakage air also represents a loss of combustion air.
  • a large gap is understood to mean a gap width which allows any ceramic element to be removed from its respective position without other elements having to be removed beforehand.
  • the contact surfaces of the ceramic elements are each adapted to the geometry of the support wall of the combustion chamber.
  • the present invention is intended for the case in which an axial assembly is not possible due to the existing spatial conditions and the individual ceramic elements therefore have to be attached to the inner wall of the housing of the combustion chamber in the radial direction.
  • the holding means are designed as bolts which engage in recesses in the housing wall provided for this purpose, preferably in the form of elongated holes.
  • the holding means are held in a form-fitting manner in the ceramic elements and are designed as screw bolts at their free end.
  • FIG. 2 shows a section of part of a combustion chamber 10 with a supporting wall 12, on the inside of which a ceramic lining 14 is arranged.
  • the ceramic lining 14 is composed of individual ceramic elements 15, 16, each of which is designed as a trapezoid and is alternately attached to and attached to the inside of the supporting wall 12 with its larger or smaller base area.
  • the base surfaces of each ceramic element 15, 16 are each adapted to the geometry of the supporting wall or the inside of the lining 14, i. i.e., convex on the side facing the supporting wall and concave on the side facing the interior of the combustion chamber 10.
  • the side surfaces of the ceramic elements are set against the base surfaces so that they enclose an angle unequal to 90 °.
  • the angle between the larger base area and the respective side area is ⁇ 90 °. Accordingly, the angle between the respective side surface and the opposite smaller base surface is> 90 °.
  • the ceramic elements 15, 16 of the lining 14 are usually mechanically connected to the supporting wall 12 in a manner known per se, not shown here in detail.
  • FIG. 3 shows a similar arrangement of a combustion chamber 10 with a supporting wall 12, as shown in FIG. 1, in which the lining 14 is formed from essentially uniform ceramic elements 18, the side surfaces of which, in contrast to the embodiment shown in FIG. 1, are in each case are aligned radially.
  • the respective contact surface of the side surfaces of adjacent ceramic elements 18 is smaller than in the embodiment according to FIG. 1, the uniform radial alignment of the side surfaces results in a non-positive connection that supports one another and thereby also ensures the gap-free state.
  • a keystone 17 is also provided in the embodiment according to FIG. 3, which is attached to the supporting wall 12 with its smaller base area and whose side faces cooperate with correspondingly adapted neighboring stones 19 in accordance with the bevel known from FIG.
  • the embodiment of a lining 14 according to the invention for a combustion chamber 10 with a supporting wall 13 shown in FIG. 4 differs from the variant shown in FIG. 2 only in that the individual ceramic elements 17, 18, 19 are fastened to the supporting wall 13 by means of threaded bolts anchored therein, which is provided with recesses not shown here for the passage of the threaded bolts.
  • the individual ceramic elements 14, 15, 16, 17, 18, 19 are placed close together in the radial direction on the supporting wall.
  • the recesses in the supporting wall are advantageously designed as elongated holes, in order, if necessary, to allow a limited lateral displacement of a ceramic element so that it lies tightly against the adjacent ceramic element.
