Definitions

  • the present invention relates to a lining for interior walls of combustion chambers with gaps left on the inner wall to be arranged, essentially plate-shaped shielding elements.
  • the invention further relates to flow barriers for use in appropriate linings.
  • Linings for internal walls of combustion chambers in particular also those for gas turbines on which the present one relates Invention also relates are known per se.
  • the combustion chambers are with essentially plate-shaped shielding elements lined which are temperature resistant and where "Basic" describes the basic dimension.
  • the shielding elements can also be designed as hollow elements.
  • To absorb different or transient thermal expansions to be able to, are usually between neighboring Leave the shielding elements in the column. Because in this column from the Combustion chamber hot gas can enter, causing overheating on shielding elements, holding elements or the combustion chamber wall can lead, it is known, between the combustion chamber wall and shielding elements to introduce sealing air so that the Columns are blocked against hot gas intake.
  • Part of the sealing air is used to cool the shielding or Fasteners needed.
  • the minimum air consumption is due to the cooling of the shielding and fastening elements necessary air volume defined. Ideally, this should be The amount of air required for cooling is also sufficient to block the gaps.
  • the blocking of the technically necessary Column (thermal expansion stationary and unsteady, manufacturing tolerances, Assembly requirements) between the shielding elements however requires significantly higher air volumes. The air requirement is therefore directly dependent on the gap area.
  • the reduction in air consumption has a positive effect on stability the burner flames, the effectiveness of the machine and pollutant emissions and enables another Increased performance while maintaining maximum material temperatures.
  • the present invention has for its object to provide a lining for the inner walls of combustion chambers with substantially plate-shaped shielding elements to be arranged on the inner wall with gap leaving, which avoids the migration of hot gases by means of economically available means by efficient sealing.
  • the invention proposes that flow barriers that can be used be used in a gap between adjacent shielding elements.
  • the flow barrier is passed through flexible, temperature-resistant sealing elements formed, which in are advantageously porous. Due to the porosity the possibility of cooling the sealing elements.
  • the sealing elements are strip-shaped and thus for gap sealing are good to use.
  • the sealing elements made from a mixture of materials such as wire mesh, Wire mesh, wire mix, fiber mix, fabric, ceramic fabric and the like are formed.
  • tubular sealing elements It is also possible to form tubular sealing elements and fill them with the appropriate material as needed.
  • the sealing elements are advantageously made by means of holders positioned in the gap area and fixed there.
  • the side edges are of the shielding elements with grooves so that strip-shaped sealing elements in the grooves and thus the Allow the column to be hidden.
  • the invention also relates to novel flow barriers for use in gaps between shielding elements of combustion chamber inner walls.
  • Such flow barriers enable efficient and targeted cooling the sealing air requirement and affect a higher flame stability as well as the ability to reduce the combustion chamber To operate flame temperature.
  • Fig. 1 shows a basic structure of, for example, on the inner wall shielding elements 1 arranged in a combustion chamber, between which there are column 2, in which according to the Invention flow barriers 3 are used.
  • the flow barriers can be fixed baffles, nozzle plates, Batch of materials, composite structures and the like.
  • Fig. 2 are in the side edges of the shielding elements 1 formed according to one embodiment grooves 4, in which an essentially rod-shaped sealing element 3 is used to form a flow barrier.
  • the sealing element 3 has holder 5, which of the attachment the sealing elements 3 serve, for example, an arbitrary Avoid longitudinal displacement.
  • Fig. 3 shows a corresponding Side view.
  • Fig. 4 shows the representation of a corresponding sealing element.
  • the holder 5 by means of a holder anchor 6, with which they form a T-shaped cross section, inserted into the sealing element.
  • the sealing element can, for example from a fabric tube, ceramic or the like exist, which is filled with appropriate filling materials is. Also can be used for longitudinal reinforcement Struts may be provided. 9 shows possible design variants of the filled hose.
  • Sealing element base 7 and holder 8 comprises.
  • the sealing element base 7 can now be provided with material for sealing accordingly be covered, for example, with a textile tube and filled, with batches, with knitted fabric, knitted fabric, Foam or the like.
  • FIG. 6 shows a strand 9 from a material mixture, for example Steel wool or the like, in an elongated Shape, indicated by the envelope 10.
  • a material mixture for example Steel wool or the like
  • FIG. 7 can such a batch strand, knitted strand or the like 9 in a groove 4 of a shielding element 1 is inserted and fixed there be, for example, by pressing, gluing, hooking or similar.
  • shielding elements 1 When putting together shielding elements 1 then results in the gap 2, the seal through contiguous batch strands 9, as shown in Fig. 8.
  • This parallel arrangement for sealing the gap in each opposite grooves in shielding elements can all embodiments of the flow barriers (fabric hose, Material mixture, baffle, composite structures and the like) can be applied.
