Definitions

  • the invention relates to a heat shield for a combustion chamber of a gas turbine.
  • 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.
  • 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 to a heat shield brick and a fastening portion attachable to the tag structure.
  • 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 series 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 made in the stone holder in the region of the holding section and in the retaining bolts of the heat shield bricks, 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.
  • cooling air can thus be flowed into the intermediate space between the cold side of the heat shield brick and the support structure when heat shield bricks are arranged on the support structure.
  • 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 intermediate 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.
  • the longitudinal axis of the device need not be identical to a longitudinal axis defined by the shape of the body. It is fictitious and, with the device arranged on the support structure, extends through the fastening region of the device and perpendicular to the surface of the support structure. Surface irregularities are not to be considered here.
  • the device is arranged below a heat shield block on the support structure.
  • the device is a threaded pin with integrated cooling air duct. Consequently, it is necessary that the threaded pin for guiding the cooling air is screwed into the existing in the support structure cooling air passage or cooling air bore.
  • the use of a threaded pin allows, for example, based on the selected angle when screwing the determination of the depth of engagement and thus the determination of the position of the heat shield brick facing end of the threaded pin.
  • the at least one output channel extends radially to the longitudinal axis.
  • the cooling air emerging from the outlet channel thus flows parallel to the support structure from an elevated position into the gap between the heat shield bricks and the support structure. This allows the cooling of a wide range of the supporting structure and at the same time avoids impact cooling of the heat shield stones.
  • the device comprises two opposing output channels.
  • This embodiment of the invention is particularly suitable for cooling a mounting groove in the support structure.
  • the device has four output channels. This enables uniform cooling of the support structure areas arranged around the device.
  • the device or the threaded pin may additionally be arranged, for example, below the crossing region of two expansion gaps on the support structure. In this area, cooling air can be injected into the respective gap between the cold side of the heat shield brick and the support structure with only one device with a corresponding number of output channels under the four adjacent heat shield bricks.
  • the combustion system 9 communicates with an annular hot gas duct, for example.
  • a plurality of successively connected turbine stages form the turbine 14.
  • Each turbine stage is formed of blade rings.
  • the hot runner of a row formed by guide vanes 17 is followed by a row of rotor blades 18.
  • the guide vanes 17 are fastened to an inner housing of a stator 19, whereas the moving blades 18 of a row are attached to the rotor 3, for example by means of a turbine disk.
  • Coupled to the rotor 3 is, for example, a generator (not shown).
  • the FIG. 2 schematically shows a device 20 for cooling a support structure of a heat shield according to a first embodiment in a sectional view.
  • the device 20 has a longitudinal axis 21 and comprises a cooling air channel 22.
  • the cooling air channel 22 extends from one end 23 of the device and comprises downstream two outlet channels 25a and 25b, which emerge laterally from the device with respect to the longitudinal axis 21 and are arranged opposite each other ,
  • the device is a threaded pin with a running inside the threaded pin cooling air passage 22.
  • the illustrated device 20 may also be referred to asdemade become.
  • the threaded pin has on its lateral surface 26 a thread (not shown).
  • the thread may, for example, in the region of the end 23 extend over the lateral surface 26 or pull to the opposite end 27.
  • the device 20 can be arranged with its end 23 on a support structure of a heat shield.
  • the cooling grommet is screwed into a provided with an internal thread cooling air hole in the support structure. In this position, cooling air exiting from the cooling air hole can be introduced into the cooling air passage 22, so that the cooling air flows downstream through the output passages 25a, 25b and leaves the cooling boot in the direction indicated by 24a and 24b.
  • FIG. 3 shows a cross section of a device 29 for cooling a support structure according to a second embodiment of the invention.
  • the cross section in this case runs perpendicular to the longitudinal axis 21 at the level of the output channels 30a and 30b.
  • the illustrated device 29 differs from the in FIG. 2 illustrateddemade only by the angle at which exit the output channels 30a and 30b with respect to the longitudinal axis 21 laterally from the device.
  • the output channels extend radially to the longitudinal axis 21 and are arranged opposite one another. Cooling air flowing through the cooling air passage 22 is divided downstream of the output passages 30a and 30b and leaves the cooling boot in the illustrated outflow direction 31a and 31b.
  • FIG. 4 shows a cross section of an apparatus 64 for cooling a support structure according to a third embodiment of the invention.
  • the cross section in this case runs perpendicular to the longitudinal axis 21 at the level of the output channels 66a, 66b, 66c and 66d.
  • the illustrated device 64 differs from that in FIG FIG. 3 showndemade only by the number of output channels.
  • the illustrated embodiment comprises four output channels, which extend radially to the longitudinal axis 21 and are arranged in pairs opposite one another. Cooling air flowing through the cooling air passage 22 is split downstream to the exit channels 66a, 66b, 66c, 66d and exits the cooling grate 64 in the illustrated directions 67a, 67b, 67c, 67d.
  • FIG. 5 shows a section of a heat shield 33 according to the invention with a support structure 34 and a number of heat shield bricks, of which a heat shield brick 35 is shown by way of example in the figure.
  • the heat shield brick 35 has a cold side 36 facing the support structure 34 and a hot side 37 which is opposite the cold side 36 and can be charged with a hot medium.
  • the heat shield brick 35 is fastened to the support structure 34 by means of stone holders 38 and 39.
  • the stone holders 38, 39 are fastened on the one hand with their attachment portions 40, 41 on the support structure 34 and on the other hand engage with their holding portions 42, 43 in retaining grooves 44, 47 on opposite side walls of the heat shield brick 35 a.
  • the heat shield brick 35 resiliently held on the support structure 34 in this way, it is possible, when the hot side 37 is acted upon by hot gases, to produce hot gas in the expansion gaps between adjacent heat shield bricks.
  • the gases which penetrate in the direction 45 are distributed here below the heat shield brick 35 in the intermediate space 46, which extends from the cold side 36 of the heat shield brick 35 to a surface region of the support structure 35 facing the heat shield brick 35. This can lead to a scaling of the support structure 34 below the heat shield brick 35.
  • a device 48 for cooling the support structure 34 below the heat shield brick is arranged on the support structure 34.
  • the device 48 is according to the illustrated embodiment, a threaded pin having a longitudinal axis 21 and a cooling air passage 22.
  • the device 48 may thus also be referred to asdemade 48.
  • the cooling grommet 48 is arranged with its longitudinal axis 21 perpendicular to the surface 51 of the support structure on the support structure, wherein thedemade 48 is screwed with an end facing the support structure 23 in a cooling air passage 50 of the support structure.
  • the cooling air passage 50 is designed as a cooling air hole.
  • the cooling air channel 22 extends from the screwed-in end 23 and comprises downstream two outlet channels 52a, 52b, which emerge laterally from the longitudinal axis 21 from the cooling grate 48.
  • Cooling air hole 50 and cooling air channel 22 correspond to each other, so that cooling air flowing from the cooling air hole enters the cooling air passage 22 and flows into the gap 46 in directions 53a, 53b by means of the cooling grommet 48.
  • the cooling air is thus introduced far away from the expansion gaps below the heat shield brick 35. This allows a particularly effective cooling of the support structure.
  • an impingement cooling of the heat shield brick 35 is avoided.
  • the cooling grommet 48 is arranged in the illustrated embodiment between two mounting portions 40, 41 of the stone holder 38, 39 centrally below the heat shield brick 35, in particular the areas of the support structure fixing the stone holder are cooled.
  • the length of the cooling air hole 50 may be selected such that the cooling grommet 48 is fully retractable during installation and removal of the heat shield bricks therein.
  • FIG. 6 shows that in Fig. 5 shown heat shield 33 in a further sectional view taken along the plane marked with arrows VI-VI.
  • the stone holders are held with their attachment portions in a mounting groove 55 on the support structure 34.
  • the cooling air hole 50 opens into the groove bottom 56 of this fastening groove 55.

  • the distance 58 is in this case chosen so that thedemade 48 does not touch the cold side 36 of the heat shield 35 and the cooling air from the output channels 52a, 52b flows into the mounting groove 55 and due to the arranged between the stone holders position of thedemade 48 in the space 46 arrived.
  • FIG. 7 shows a section of a heat shield 60 according to the invention according to a fifth embodiment.
  • This is different from the one in Figure 5 represented in that in addition in the groove bottom of the mounting groove a cooling air groove 62 extends.
  • Thedemade 48 is lowered to the level of the groove bottom of the mounting groove in the cooling air hole 50, wherein the output channels 52a, 52b of thedemade 48 open in the longitudinal direction in the cooling air groove 62.
  • This has the advantage that the stone holder can be moved over thedemade 48 away for installation and removal of the heat shield bricks 35 through the mounting groove.
  • the function of thedemade 48 remains hereby.
  • the effluent from thedemade 48 cooling air is injected into the cooling air groove 62 and flows at the ends by means of an outlet 63 in the gap 46 between the cold side of the heat shield brick 35 and the support structure 34 and cools the Support structure 34 below the heat shield brick 35 while avoiding a baffle cooling of the same.
