Definitions

  • the invention relates to a heat shield assembly comprising a support structure and a heat shield, wherein the heat shield has a cold side resting on the support structure and a hot side opposite the cold side and a peripheral side connecting the cold side to the hot side, wherein at least one recess is introduced into the peripheral side of the heat shield is.
  • high temperature gas reactors such as pressurized combustors such as those used in gas turbines
  • high thermal stresses such as hot gas
  • ceramic materials offering high temperature resistance, corrosion resistance and low thermal conductivity are suitable for this purpose.
  • Such a heat shield goes out of the EP 0 558 540 B1 out.
  • a heat shield for the combustion chamber of a gas turbine with a support structure which has a hot side and a cold side and an edge connecting the hot and cold side.
  • the flank gripping tabs are introduced, in which holder engage for attachment of the heat shield to the support structure, the holder overlap the flanks partially.
  • the support structure have grooves. The holders are pushed into these grooves. The holders are thus secured in the support structure and thereby partially clasp the heat shield on its flanks.
  • the cross-sectional profile is designed so that the end of the holder which is made with the largest width, is held in the groove.
  • the slightly narrower executed spring portion of the holder can be bent from the groove base for applying the retaining bias.
  • the retaining elements remain displaceable in the groove, but are perpendicular to the support structure surface held positively.
  • the holders no longer need to be fastened to the support structure with screws.
  • a disadvantage of this method of attachment is that the heat shields, which line the combustion chamber interior, for attachment to the support structure always row by row and always have to be fixed sequentially (attachment in the circumferential direction). This means that in the case of a leading to replacement findings on the heat shield, this can not be replaced individually. Rather, a chain of heat shields -aus obtained to be replaced from a mounting start position to the heat shield to be replaced, with the risk of dismantling damage. This represents on the one hand a high workload and on the other high material costs by replacing the damaged only when disassembled heat shields, but also by the longer working hours.
  • US 5243801 A describes a heat shield assembly comprising a support structure 27 and a heat shield 40, wherein the heat shield 40 has a resting on the support structure 27 cold side 42 and the cold side 42 opposite hot side 41 and a peripheral side 43 which connects the cold side 42 with the hot side 42, wherein the circumferential side 43 of the heat shield 40 is a recess 46 is introduced, wherein a in the direction substantially perpendicular to the recess 46 extending recess 47 is provided, which extends from the recess 46 to the cold side 42 and wherein for fixing the heat shield 40 to the Supporting structure 27, a fastening bolt 60 is inserted into the recess 47 and wherein the fastening bolt 60 has a bolt head 62.
  • the object of the invention is therefore to provide an improved heat shield assembly, which is particularly easy to service during maintenance and installation.
  • the heat shield assembly should be usable in a combustion chamber for gas turbines.
  • a heat shield arrangement comprising a support structure and a heat shield, the heat shield having a cold side resting on the support structure and a hot side opposite the cold side, and a peripheral side connecting the cold side to the hot side, wherein at least one of the peripheral sides of the heat shield Recess is introduced, wherein a recess extending in the direction substantially perpendicular to the recess is provided, which extends from the recess to the cold side and wherein a fastening bolt is inserted into the recess for attachment of the heat shield to the support structure.
  • the invention is based on the finding that a recess can be introduced into the heat shield on the cold wall side, without causing a noticeable weakening of the heat shield with regard to shortened service life. Therefore At least one recess is introduced into the peripheral side. Starting from this recess, a recess is introduced. This extends from the recess to the cold side, that is to the support structure. In this recess, a fastening bolt is introduced. By means of this fastening bolt, the heat shield is attached to the support structure. The fastening bolt in the interior of the heat shield and the support structure is thus accessible from the outside.
  • the bolt is thus combustion chamber inside accessible and detachable from the support structure.
  • the heat shield is thus individually solvable from a chain of heat shields.
  • the fastening bolt has a bolt head. This pushes the heat shield on the support structure.
  • the fastening bolt comprises a holding plate.
  • the heat shield As a result, the direct contact of the bolt head is avoided with the heat shield.
  • the pressure occurring by means of which the heat shield is clamped tightly to the support structure is transmitted as uniformly through the retaining plate to the heat shield. Furthermore, it serves as a spacer to the adjacent heat shield. The fastening bolt is thus also secured against slipping in the recess.
  • the retaining plate of the fastening bolt is cooled by means of at least one cooling opening.
  • the retaining plates can be cooled by the support structure with targeted cooling air jets or coolant streams. In this case, not only the retaining plate is cooled, but also prevents entry of hot gas into the gaps of adjacent heat shields.
  • the heat shield on the peripheral side on two opposite retaining plates for attaching the heat shield to the support structure.
  • these two retaining plates partially surround the peripheral side in the direction from the cold side to the hot side.
  • the retaining plates are plugged into the recess for fastening the heat shield to the support structure.
  • only one retaining plate has a slot on a facing side of two adjacent heat shields. In the case of two adjacent retaining plates, only one is thus configured with the fastening bolt according to the invention in the recess according to the invention.
  • the other retaining plate may for example be attached to the support structure as in the prior art.
  • the heat shield is provided with only one recess, which is advantageous for the resistance of the heat shield, since the thermal expansion of the heat shield is not hindered.
  • a heat shield assembly always has a prior art fastener and a fastener according to the invention.
  • their common side therefore advantageously has different fastenings.
  • resiliently fixed screws are also mounted in the support structure. These then press the retaining plate to a bias. During assembly, fastening bolts and retaining plate can be inserted laterally into the heat shield.
  • the fastening bolt is a screw holder.
  • a thread is provided in or on the support structure.
  • To attach the screw is tightened, that is, a tension exerted on the heat shield.
  • the bolt head is at least partially inserted in the recess. This has the advantage that the bolt head is largely protected in the recess against, for example hot gas. In addition, the force that presses the bolt head against the heat shield, transferred to the heat shield better.
  • the fastening bolt is sprung. By a suspension of the fastening bolt, the torque of the fastening bolt can be adjusted more targeted.
  • the recess is centrally inserted in the peripheral side.
  • a central attachment of the recess increases the resistance of the heat shield with respect to cracking and breakage. If the peripheral side is divided by the recess into two very different halves, fractures and cracks can be created much more easily due to the smaller material thickness in the thinner half.
  • the recess is designed as a longitudinal groove. This can be easily realized in terms of manufacturing technology.
  • the recess is designed as a holding pocket. This not only the vertical fixation of the heat shield, but also an axial fixation is possible. Thus, an increase in the strength of the heat shield in the region of the holder is given in comparison with the execution of the longitudinal groove.
  • the holding pocket also focuses the coolant on the holding elements and thus reduces the coolant requirement. In addition, the rework can be reduced here. Furthermore, this can cause a further saving of coolant, since this is a substitute for the used in the prior art final heat shields can be used.
  • a hole aligned with the bolt head is mounted in the heat shield from the hot side.
  • the fastening bolt from the hot side that is inside the combustion chamber, forth solvable.
  • the fastening bolt is air-cooled from the inside.
  • the fastening bolts are cooled by the air itself. Furthermore, it is prevented by the outflowing air that hot gas enters the recess. This has a life-prolonging effect on the fastening bolts.
  • the support structure has cooling openings.
  • the fastening bolts and the retaining plates are supplied with cooling air on the one hand.
  • the cooling can be used very effectively and selectively, for example by impingement cooling of the retaining plates, whereby the cooling air consumption is minimized.
  • At least one cooling opening on the retaining plate and thus causes a particularly good cooling.
  • the heat shield is preferably made of ceramic material, in particular a porous ceramic.
  • the fastening bolt is made of metal or metal alloy.
  • the gas turbine 1 has a compressor 2 for combustion air, a combustion chamber 4 and a turbine 6 for driving the compressor 2 and a generator or a work machine, not shown, in the compressor 4, compressed air L is compressed.
  • the turbine 6 and the compressor 2 are arranged on a common, also called turbine rotor turbine shaft 8, with which the generator or the working machine is connected, and which is rotatably mounted about its central axis.
  • the turbine 6 has a number of rotatable blades 12 connected to the turbine shaft 8.
  • the blades 12 are arranged in a ring on the turbine shaft 8 and thus form a number of blade rows.
  • the rotor blades 6 serve to drive the turbine shaft 8 by momentum transfer from the hot medium flowing through the turbine 6, the working medium, for example the hot gas M.
  • the guide vanes 14, serve to guide the flow of the working medium, for example the Hot gases M.
  • resulting hot gas M flows in the flow direction S from the combustion chamber 4 to the turbine 6.
  • For the combustion chamber 4 is designed with heat shields.
  • FIGS. 2 and 3 show the heat shield assembly 20 with a heat shield 22 and a support structure 28 at a time from obliquely above and in cross section.
  • a heat shield is shown with a retaining plate 48 according to the prior art.
  • the heat shield 22 has a hot side 24, a cold side 26 and a peripheral side 30.
  • a recess 34 is located advantageously approximately in the middle of the peripheral side 30.
  • a recess 32 extends from the recess 34 to the cold side 26 of the heat shield 22.

  • the screw holder 36 has a bolt head 38.
  • a holding plate 40 is attached in such a way that the expansion of the heat shield 22 and the screw holder 36 is possible.
  • the direct contact of the head 38 with the heat shield 22 in the recess 34 is avoided.
  • the occurring pressure by means of which the heat shield 22 is firmly clamped to the support structure 28 is transmitted as evenly through the retaining plate 40 to the heat shield 22.
  • it serves as a spacer to the adjacent heat shield. This ensures a slip-proof fastening.
