Definitions

  • the invention relates to a device for cooling the support structure of a heat shield and to a heat shield, in particular to a heat shield for a combustion chamber of a gas turbine.
  • the invention also relates to a combustion chamber and to a gas turbine with such a heat shield.
  • heat shields are used, which must withstand hot gases of 1000 to 1600 degrees Celsius.
  • gas turbines such as those used in power-generating power plants and in aircraft engines, have correspondingly large surfaces to be shielded by heat shields in the interior of the combustion chambers.
  • the heat shield must be composed of a plurality of individual, generally ceramic heat shield bricks, spaced apart from each other with a sufficient gap to a support structure. This gap provides the heat shield elements with sufficient space for thermal expansion.
  • cooling air is injected as a countermeasure through the gaps in the direction of the combustion chamber.
  • a generic heat shield thus comprises a support structure and a number of heat shields, which are releasably secured to the support structure by means of stone holders, each heat shield brick having a support structure facing cold side and the cold side opposite, acted upon by a hot medium hot side.
  • Each of the stone holders has at least one holding section for attachment on a heat shield brick and attachable to the tag structure attachment portion.
  • at least one cooling air passage is provided in the support structure.
  • circular circumferential and parallel fastening grooves may be provided in the support structure.
  • the stone holders are inserted in this case with their attachment portions one after the other in the mounting grooves, with subsequent stone holder block the position of the previously positioned stone holder.
  • a circular encircling row of heat shield bricks may be secured to the support structure within a combustor of a gas turbine.
  • the EP 1 701 095 A1 discloses a heat shield of a combustor of a gas turbine having a support structure and a number of heat shield bricks disposed releasably on the support structure.
  • the heat shield bricks are arranged across the surface, leaving expansion gaps on the support structure, wherein each heat shield brick has a cold-side facing the support structure and a hot side which is opposite to the cold side and can be charged with a hot medium.
  • the heat shield bricks are resiliently fastened to the support structure with four metallic stone holders each.
  • each stone holder comprises a holding section in the form of a gripping section and a fixing section.
  • each heat shield brick side retaining grooves are introduced on two opposite circumferential sides, so that for holding the heat shield brick, the gripping portions of the stone holder opposite can engage in the retaining grooves.
  • the stone holders which are fastened on the heat shield brick in opposite directions, are guided with their fastening portion in a fastening groove extending below the heat shield brick in the support structure.
  • the gripping portions of the metallic stone holder are cooled.
  • openings are provided in the stone holders in the area of the holding section and in the holding bars of the heat shield bricks introduced, which are aligned with a cooling air hole arranged in the support structure, so that cooling air from the cooling air hole flowing in direct line on a cold side of the gripping portion bounces.
  • a device for cooling the support structure of a heat shield of the type mentioned above in that the device comprises a longitudinal axis and a cooling air duct, wherein the device with the longitudinal axis perpendicular to the surface of the support structure on the support structure can be arranged.
  • the cooling air duct extends from an end of the device facing the support structure and comprises at least one outlet channel downstream.

  • the cooling air can be introduced into the intermediate space by means of the device from an elevated position above the support structure.
  • the cooling air flows laterally out of the device into the space. This avoids damage to the heat shield stones by impingement cooling and the cooling air is distributed below the heat shield bricks without immediately escape through the expansion gaps between the heat shield bricks. This allows effective cooling of the support structure of the heat shield while avoiding damage to the heat shield stones.
  • cooling air duct corresponds to at least one cooling air passage arranged in the support structure
  • the cooling air duct corresponds to at least one cooling air passage arranged in the support structure
  • the cooling air passage can be, for example, a cooling air bore arranged in the support structure, into which the device can be screwed with its end facing the support structure.

  • the device between two attachment portions of the stone holder is arranged substantially centrally under a heat shield brick.
  • the device is located between two attachment portions of two opposing stone holders, which hold a common heat shield brick on opposite side walls of the heat shield brick. In this way, the cooling air emerging from the device can be injected below the heat shield brick without the stone holders blocking the flow path of the cooling air.
  • a cooling air groove runs in the groove bottom of the fastening groove and the device is lowered into the cooling air bore at least at the height of the groove bottom, the outlet channels of the device opening into the cooling air groove.
