Definitions
- the invention relates to a heat shield component which is part of a hot gas wall to be cooled. Furthermore, the invention relates to a heat shield arrangement which lines a hot gas space, in particular a combustion chamber of a gas turbine system, and has a plurality of heat shield components.
- Craemer proposes a panel consisting of four components that is to be mounted on the inside of a combustion chamber housing.
- the upper layer facing the hot gas space consists of a refractory metal, but can also be formed from a ceramic material.
- Below this is a layer of steel wool-like metallic filaments. This rests on a ner larger number of columnar supports. These pillar-like supports and the cavities in between form the third layer.
- the columnar supports are attached to a fourth metallic layer.
- the steel-wool-like metallic filaments of the second layer absorb heat energy from the layer above, which forms the inner wall of the burner, and pass it on to the air flow guided between the column-like supports.
- the cavities of the third layer are connected via channels that lead through the fourth layer and the burner housing to a space outside the burner, which is fed with air via a compressor. The compressed air can pass through these channels as a coolant into the cavity formed by the layers.
- a second type of channel is distributed over the front and middle area of the combustion chamber, through which air originating from the exterior of the combustion chamber reaches the combustion chamber through the combustion chamber housing and the layered panels.
- Craemer's proposal has the disadvantage that cool air flows into the combustion chamber over the entire area of the combustion chamber without having participated in the combustion. As a result, the temperature at the exit of the combustion chamber drops.
- EP 0 224 817 B1 describes a heat shield arrangement, in particular for structural parts of gas turbine systems.
- the heat shield arrangement has an inner lining made of heat-resistant material, which is composed of heat shield elements anchored to the support structure to cover the entire surface. These heat shield elements are arranged next to one another, leaving gaps for the flow of cooling fluid, and are heat-mobile.
- Each of these heat shield elements has a hat part and a shaft part in the manner of a mushroom.
- the hat part is a flat or spatial, polygonal plate body with straight or curved border lines.
- the shaft part connects the central area of the plate body with the support structure.
- the hat part preferably has a triangular shape, which means that identical hat parts can be used to produce an inner lining of almost any geometry.
- the hat parts and possibly other parts of the heat shield elements consist of a high-temperature-resistant material, in particular a steel.
- the support structure has bores through which a cooling fluid, in particular air, can flow into an intermediate space between the hat part and the support structure and from there through the gaps for the cooling fluid to flow into a space area surrounded by the heat shield elements, for example a combustion chamber of a gas turbine system. This flow of cooling fluid reduces the penetration of hot gas into the space.
- the wall is preferably arranged between a hot space and a cooling fluid space. It is assembled from individual wall elements, each of the wall elements being a plate body made of highly heat-resistant material. Each plate body has parallel cooling channels distributed over its base area, which communicate with the cooling fluid space at one end and with the hot space at the other end. The cooling fluid flowing into the hot space and guided through the cooling fluid channels forms a cooling fluid film on the surface of the wall element and / or adjacent wall elements facing the hot space.
- the post-published WO 98/13645 AI describes a heat shield component with cooling fluid return with a hot gas wall to be cooled, an inlet channel for cooling fluid and an outlet channel for the cooling fluid, the inlet channel being directed towards the hot gas wall and expanding in the direction of the hot gas wall.
- the inlet duct is largely surrounded by the outlet duct.
- the support structure is designed as a two-wall structure with an outer wall and an inner wall which is arranged parallel to the same and is adjacent, leaving an intermediate space.
- the heat shield component has a fastening part on the outlet duct, with which the outlet duct is placed on the outer wall and fastened thereon.
- the outer wall Inside the outlet duct, the outer wall has an opening through which the inlet duct is passed leaving a gap.
- the inner wall has a further opening into which the inlet channel is inserted over a short length. Cooling fluid can be supplied to the heat shield component via the inlet channel and can be removed via the outlet channel.
- the inlet duct is covered with a cover wall which has impingement cooling openings. Through the baffle cooling opening from the inlet channel supplied cooling fluid impact against the hot gas wall, which is cooled.
- the object of the invention is to provide a heat shield component that can be cooled with a cooling fluid for a hot gas chamber of a system, and a heat shield arrangement with heat shield components that enable economical operation of the system.
- the object directed to the heat shield component is achieved according to the invention by a heat shield component which can be attached to a support structure, with an outer hollow body which encloses an insert with an intermediate space formed between the outer hollow body and the insert, the outer hollow body having a first bottom side which can be applied to a hot gas and Has side walls and wherein the insert has side walls and a second bottom side with a plurality of openings for the passage of cooling fluid into the intermediate space, the outer hollow body and the insert each being attachable to the support structure.
- the heat shield component can be attached to the support structure without the heat shield component having to penetrate the support structure.
- the support structure can largely be designed with a closed surface, with smaller openings, such as bores or the like, being provided, for example for fastening the heat shield component in the support structure, which are mechanically simple to attach.
- the side walls of the insert can preferably be placed on the support structure in such a way that an interior space is formed which is delimited by the insert and the support structure.
- an interior fluidically connected via the openings to the intermediate space is formed, into which a cooling fluid can first be introduced, which through the openings into the Intermediate space flows and impinges against the first bottom side to cool it.
- the upper edges of the side walls of the hollow body rest on the support structure along the full circumference of the heat shield components and cause the space in which the cooling fluid is located to be largely sealed off from the hot gas space.
- the side walls of the hollow body advantageously have a geometry which makes it possible to introduce a seal between the hollow body and the supporting structure.
- the seal can be designed, for example, as a press seal. Due to the geometry of the hollow body, the seal lies on the cold side of the heat shield component.
- the insert is more preferably interchangeable.
- the heat shield component is designed such that the insert or the outer hollow body can in each case be replaced alone.
- a first and a second outer hollow body can preferably be attached next to one another on the supporting structure, a side wall of the first outer hollow body and a side wall of the second outer hollow body being adjacent while leaving a gap, the side walls each having a surface contour such that the gap is wound .
- the gap forms a throttle point, via which it is difficult for hot gas guided outside the heat shield component to penetrate into the gap or for cooling fluid emerging from the heat shield component to pass through the gap. This can be achieved, for example, by interlocking steps or toothing of adjacent side walls of hollow bodies.
- the inner bottom side of the hollow body can preferably have cooling fins or the like, as a result of which cooling with a cooling fluid can be optimized.
- the heat shield components are preferably attached to the supporting structure by means of a centrally attached retaining bolt.
- the retaining pin can be provided with disc springs so that greater flexibility is guaranteed if the heat shield component exceeds the permissible expansion.
- the retaining bolt can be attached to the hot side of the heat shield component. But it is also possible that the retaining bolt is located on the cold side of the heat shield component. The latter has an advantageous effect on the corrosion properties of the heat shield component.
- the bottom side of the hollow body can optionally have a triangular, quadrangular (in particular square or trapezoidal) or hexagonal base area. Other suitable geometries are also possible.
- the typical order of magnitude is 200 mm edge length.
- the wall thickness of the bottom side of the hollow body is preferably less than 10 mm, particularly preferably between 3 and 5 mm. This ensures a relatively small temperature difference between the inside and outside surface of the bottom side of the hollow body. This means that the heat shield component can withstand high load changes.
- the heat shield component consists of a heat-resistant material, in particular a metal or a metal alloy. It is advantageous to manufacture the heat shield component, in particular the hollow body, as an investment casting.
- a plurality of heat shield components arranged side by side on a support structure comprises, one heat shield component being attachable to the support structure and having an outer hollow body which encloses an insert with an intermediate space formed between the outer hollow body and the insert, the outer hollow body having a first bottom side which can be exposed to hot gas and has side walls and wherein the insert has side walls and a second bottom side with a plurality of openings for the passage of cooling fluid into the intermediate space, wherein the outer hollow body and the insert are each attachable to the support structure and wherein one can be exposed to a hot gas through the bottom sides of the heat shield components Wall of a hot gas-carrying component, in particular a combustion chamber of a gas turbine system, is formed.
- a hot gas-carrying component in particular a combustion chamber of a gas turbine, can be lined with such a heat shield arrangement, the heat shield arrangement protecting the supporting structure, which can be, for example, a wall of the combustion chamber, against the effects of heat from the hot gas.
- the individual heat shield components can be cooled with a closed cooling fluid circuit.
- the support structure for the heat shield components preferably has an inlet channel for cooling fluid and an outlet channel into the intermediate space for cooling fluid in a first region within the side walls of the insert.
- cooling fluid can be guided via the inlet channel into the use of a heat shield component, from which the cooling fluid passes through the openings into the intermediate space for impact cooling of the respective first bottom side.
- the cooling fluid can be removed from the intermediate space via the outlet channel.
- the inlet duct is further preferably connected to a supply duct which is arranged outside the hot gas space and the outlet duct is connected to a discharge duct which is likewise arranged outside the hot gas space. Cooling fluid can thus be supplied to the inlet channel via the supply channel and the cooling fluid heated after the impingement cooling can be discharged via the outlet channel and a discharge channel. This allows cooling fluid to be guided into a closed cooling fluid circuit.
- the cooling fluid can preferably be supplied from a compressor, in particular a gas turbine, via the supply duct to the heat shield component and is discharged via the discharge duct, in particular being supplied to a burner.
- the cooling fluid can thus easily be removed from a compressor and, after cooling, can be fed to a burner for combustion when heated. All of the compressor air can thus be supplied to the combustion.
- Hot gas temperature is adjustable. This is associated with a reduction in nitrogen oxide pollution. Due to the closed cooling air return, there is also no flow around the edges of a heat shield component, so that a largely uniform temperature distribution with low thermal stresses arises in its material.
- the supply of the heat shield components with cooling air and the return of the heated cooling air to a burner of the gas turbine system is preferably carried out via axially parallel Supply channels.
- the ducts can be expanded as required in the radial direction and their cross-sections adapted to the required cooling air quantities. All heat shield components therefore have essentially identical cooling air entry conditions.
- the flow path to the heat shield components or heated cooling air to the burner has only a small pressure drop due to its shortness.
- the heat shield components arranged on an outside of a rotationally symmetrical hot gas-carrying component, in particular a combustion chamber of a gas turbine system are preferably supplied via the guide vanes of the first row of guide vanes of the gas turbine. If the amount of cooling air that can be guided through the guide vanes is not sufficient for sufficient cooling of the heat shield components, it is possible to guide supply channels past the hot gas-carrying component, in particular the combustion chamber, to the outside thereof.
- the return of the heated cooling air is preferably carried out via separate discharge channels which lead directly to a burner of the gas turbine system. It is also possible to have the outlet duct of the heat shield components open directly into a main duct, in which the compressor air is fed to the burner. As a result, the heat absorbed in the heat shield components can be fed back to the gas turbine process in a particularly favorable manner.
- 1 shows a gas turbine system, partially cut open in the longitudinal direction, with an annular combustion chamber, 2 shows a longitudinal section through a heat shield component
- Support structure, feed and discharge channel and 3 shows a sectional view of the side walls of adjacent hollow bodies, which are applied to a support structure.
- the gas turbine system 10 has a shaft 26 and has a compressor 9, an annular combustion chamber 11 and the blading (guide blades 18, moving blades 27) connected in series in the axial direction.
- Combustion air is compressed and heated in the compressor 9, which air is partially supplied as a cooling fluid 4 to a heat shield arrangement 20.
- the compressed air is fed to a plurality of burners 25, which are arranged in a ring around the annular combustion chamber 11.
- a heat shield component is shown schematically in FIG.
- the heat shield component has the overall reference number 1. It has a hollow body 100 on the bottom side 101 of which can be exposed to hot gas. This (“first”) bottom side 101 is exposed to a hot gas flow 29.
- the hollow body 100 is laterally delimited by the side walls 102. These side walls 102 stand with their lower edge on the Support structure 17.
- In the hollow body 100 there is a further smaller hollow body than the insert 110.
- This insert 110 has passage openings 113 on its bottom side 111.
- the insert 110 is laterally delimited by its side walls 112.
- the edge of the side walls 112 stands on the support structure 17. This forms an interior space 150 which is delimited by the insert 110 and the support structure 17.
- an intermediate space 151 is thereby formed, which is limited by the insert 110, the hollow body 100 and the supporting structure 17.
- the support structure 17 In the area 162, which is located between the side walls 112 of the insert 110, the support structure 17 has one or more inlet channels 3 through which a cooling fluid 4 can get into the interior 150.
- the support structure 17 also has outlet channels 5 in the intermediate space 151.
- cooling fluid 4 flows through the inlet channels 3 into the interior 150 of the insert 110 and passes through the through openings 113 into the intermediate space 151, where it strikes the inside 103 of the bottom side 101.
- the cooling fluid that is heated after the impingement cooling is discharged from the intermediate space via the
- the cooling fluid 4 is thus guided in a closed circuit. This prevents the cooling fluid 4 from entering the hot gas space 37.
- seals 34 make it possible to prevent leakage flows between the support structure 17 and the side wall 102 of the hollow body 100 seated thereon.
- the seals 34 are designed here as squeeze seals, the side wall 102 of the hollow body 100 having a shoulder through which the seal 34 is pressed onto the support structure 17 in the region of the connection point between the side wall 102 of the hollow body 100 and the support structure 17.
- the supply of cooling fluid 4 takes place in such a way that the cooling fluid 4 is supplied to the inlet ducts 3 from a compressor 9 through a supply duct 12.
- This supply channel 12 is located outside the hot gas space 37.
- the cooling fluid 4 is discharged via a discharge channel 13 which is also outside the hot gas space 37.
- the cooling fluid 4 can be supplied to the burner 25, for example, through this discharge channel 13.
- the heat shield component 1 is fixed on the supporting structure 17 by a holding bolt 130.
- This holding bolt 130 is arranged in the middle of the rectangular embodiment shown. Its axis is aligned along the major axis 32 of the heat shield component.
- the retaining bolt is designed with a thickening on the hot side of the heat shield component 1 and is mounted on the support structure 17 with its thinner end.
- the retaining bolt can be provided with disc springs, not shown here, in order to compensate for exceeding the permissible thermal expansion of the heat shield component 1.
- the insert 110 and the hollow body 100 are mechanically detachably connected only via the retaining bolt 130, the inserts can be exchanged for other inserts which are used in the
- the cooling conditions for the bottom side 101 of the hollow body 100 can be adapted to the specific requirements which result from the position of the heat shield component 1 in the hot gas duct.
- the heat shield arrangement is made up of a plurality of heat shield components arranged on the support structure 17. ten formed, with only two heat shield components 100 and 100A being shown for a better overview, two side walls 102 and 102A of two adjacent hollow bodies 100 and 100A and part of the support structure 17 being visible. 115 and 115A indicate cooling fins running radially to the side walls 102 on the first bottom side.
- the bottom sides 101 and 101A of the heat shield components 100 and 100A form a wall 160 which can be attached to a hot gas with the bottom sides of the heat shield components which are not shown in any more detail.
- the adjacent side walls 102 of the hollow body 100 have a mutually corresponding surface contour.
- This surface contour is designed such that the side wall 102A of the hollow body 100A shown in the drawing on the right side has a shoulder 105 which corresponds to a counter-shoulder 104 of the side wall 102 of the hollow body 100 shown on the left side.
- This shape with shoulder 105 and counter shoulder 104 ensures that no linear gap 36 leads from the hot gas space 37 to the supporting structure 17.
- the hollow bodies 100 can be produced using the precision casting process, geometries such as the one described do not pose any manufacturing difficulties. Of course, it is also possible to choose other geometries for the side walls 102 and 102A of the hollow bodies 100 and 100A, in which a linear gap between the hot gas space 37 and the support structure 17 is avoided.
