Definitions
- the invention relates to a flow barrier as an insert in a flow region between a first and a second cladding element of a lining of a combustion chamber.
- the invention leads to a fairing and a combustion chamber.
- a combustion chamber in particular the combustion chamber of a gas turbine combustion chamber of a gas turbine, is usually provided with a lining in order to insulate and protect the housing parts of the combustion chamber-carrying housing, also referred to as combustion chamber structure.
- the combustion chamber conditions prevailing in the combustion chamber which are characterized in particular by strongly fluctuating and high temperatures, pressures and oxidizing effects of the hot gas, are kept away from the housing.
- a region of the housing is to be protected, in which the holder of the panel is attached.
- the thermal loads are usually in a temperature range of 1350 ° C or above and can also, for. B. subject to strong fluctuations in the context of a quick closure.
- the metallic housing is usually not suspendable.
- the housing and the holder are therefore also to protect against a progressing with time material fatigue, the material fatigue is higher, the more frequent and larger temperature and pressure fluctuations occur in the combustion chamber.
- the cladding usually has a number of cladding elements. Particularly advantageous is a formed from a ceramic cladding element, as a heat shield (Ceramic Heat Shield, CHS) proven. Another possibility is to form a cladding element of a high temperature resistant metal alloy. On a metallic cladding element, a ceramic coating can be applied.
- a gap is set in the assembly of a trim element on the entire circumference of the trim element.
- the cladding elements of the panel are therefore mounted at a distance. This clearance provides a flow area between a first and a second trim element of the trim.
- a cooling air flow running between the housing part and the lining is guided during operation of the combustion chamber. This serves in particular for cooling the holder, which holds a cladding element on the inside of the housing part facing a combustion chamber.
- the cooling air can penetrate through the flow region into the combustion chamber.
- the gaps are to be protected from the combustion chamber side penetrating hot gas intake.
- the cooling air is guided from the housing part and the back of the panel forth in the direction of the combustion chamber, to block in this way a gap with the cooling air.
- the flow barrier thus has to meet a wide variety of requirements.
- the flow barrier should on the one hand take account of a width of the flow region which varies as a result of thermal changes and on the other hand should be heat-resistant.
- porous ceramic gaskets are made of EP 1 302 723 A1 known. Although such a porous ceramic gasket is resistant to high temperatures, it must not come into direct contact with the hot gas. Since this contact in the combustion chamber is difficult to avoid, such a porous ceramic seal must be flowed through by cooling air in order to cool the seal itself and also to block the flow region from a hot gas intake. Nevertheless, in porous ceramic gaskets of the type mentioned overheating occurred. The essential reason is that a sufficient in each case a real operation of a combustion chamber flow through the porous ceramic seal with cooling air is difficult to guarantee.
- a cladding element when using the usual concept explained here at its edge due to the cooling air outlet at a significantly lower temperature than at its center facing the combustion chamber.
- a usually panel-shaped cladding element has a relatively high rigidity along its lateral extent. The high temperature gradient along the lateral extent and the stiffness along the lateral extent together lead to considerable stresses along the lateral extent of the cladding element.
- the US 5333443 A discloses a flow barrier for use in a flow region between first and second trim members of a combustor of a gas turbine engine.
- the flow barrier is secured to a support structure carrying the trim elements and includes a screw and a stack of rectangular stacked sheet-like seals which are urged by the screw and a coil spring surrounding the screw to seal against the trim elements.
- the seals are offset from each other and arranged several times, so that there is a seal of the flow area.
- the US 6145452 A discloses hexagonal cladding elements of a combustor which are attached to a support structure at a central bore by means of a helical fastener made of ceramic.
- the invention is whose task is to provide a flow barrier, which is resistant to heat and at the same time can be used in a variable-shape, varying in size flow area and which is as simple as possible.
- a further object of the present invention in terms of the lining and the combustion chamber with such a flow barrier is to take into account the problems explained in connection with the cooling air.
- a flow barrier for use in a flow region between a first and a second cladding element of a lining of a combustion chamber, wherein the flow barrier has a high temperature resistant ceramic body and a spring element and the high temperature resistant ceramic body and the spring element have an elongated extent, wherein the ceramic body rests along a bearing surface on the spring element, and the bearing surface is aligned along the elongate extent.
- the invention has recognized that a hitherto customary porous ceramic flow barrier leads to a number of consequential problems which are avoided according to the concept of an overall high-temperature-resistant flow barrier explained here.
- the use of a high temperature resistant ceramic body as part of the flow barrier ensures that the flow barrier has sufficient hot gas resistance, which is independent of a cooling air flow.
- an alumina ceramic has been found. It can also be used depending on the usefulness of another high-temperature resistant ceramic.
- the sufficient hot gas resistance of the high-temperature resistant ceramic body has, in particular, the particularly reliable and reliable effect of the flow barrier in comparison to conventional porous ceramic flow barriers.
- the combination of the high-temperature resistant ceramic body with a spring element to a flow barrier also has the effect according to the finding of the invention that the barrier effect of the flow barrier achieved by the spring force acting on the ceramic body proves to be particularly effective.
- the combination of the high-temperature resistant ceramic body and the spring element to a flow barrier proves to be particularly adaptable when used in a highly variable shape and distance flow region between the first and the second cladding element as a result of temperature fluctuations.
- the parts, d. H. the high-temperature resistant ceramic body and the spring element, the flow barrier can be easily manufactured and thus produced inexpensively.
- the invention is thus, in departure from the known porous ceramic flow barrier, from the new and surprising in its effect consideration that compared to a porous ceramic flow barrier the flow barrier explained here with a relatively rigid high-temperature resistant ceramic body yet to a reliable sealing of the flow area leads.
- the flow barrier according to the new concept namely as sufficiently variable within the variable-shape flow area.
- the high temperature resistant ceramic body and the spring element have an elongated extent, wherein the ceramic body rests along a bearing surface on the spring element and the bearing surface is aligned along the elongate extent.
- elongated spring elements can be assembled particularly easily and mounted in a flow region of a lining of a combustion chamber. Its elongated extent accounts for the elongate extent of the flow area between a first and a second trim element of the fairing.
- the support surface is curved towards the spring element.
- the spring element on its side facing the support surface on a trough and the high-temperature resistant ceramic body on its side facing the support surface on a bulge are suitably adapted to each other, so that the ceramic body in the spring element comes to rest securely and is secured against lateral slipping in the trough.
- the spring element expediently has retaining means which ensure the position of the high-temperature-resistant ceramic body along the elongate extension.
- the ceramic body is also in an axial direction, ie in a direction of elongated extent, against a Secured slipping.
- a stop or a sufficiently rough design of the bearing surface between the spring element and the ceramic body is particularly suitable.
- the spring element is formed at least along a fraction of the elongated extent in the form of a spring subjected to compression according to the operating principle of a disc spring. That is, the spring element is, except for its elongated extension (instead of a round in a plate spring), formed in principle like a plate spring and is based in principle on the same mechanism of action as a plate spring.
- the spring element is formed along a further fraction of the elongated extension in the form of a bare support. It has proved to be particularly useful to form the spring element along a central part of the elongated extension in the form of a compression spring, clip-like, after the operating principle of a disc spring and form along its lateral parts of the elongated extension in the form of a bare support.
- the supports support the high-temperature resistant ceramic body in its edition while in the middle part of the spring force is generated.
- the spring element is formed at least along a fraction of the elongated extent in the form of a pressure-loaded, resiliently yielding solid body.
- any type of material comes into consideration, which gives the solid body a pressure-loaded resilient effect. It can be a uniform solid material or a composition or a conglomerate of different materials.
- a cross section through the solid body advantageously has a shape that is similar to the shape of a horizontal figure eight.
- the object with regard to the cladding is achieved by a cladding for a combustion chamber with a number of cladding elements, wherein between a first and second cladding element, a flow region is formed, in which a flow barrier of the above type is used.
- one or more flow barriers are inserted into the flow region in such a way that the flow region is completely sealed by the one or more flow barriers. In this way, namely a hot gas intake into the flow area is completely prevented.
- One or more of the flow barriers are particularly advantageously used in all flow regions extending along a circumference of a cladding element. To this In this way, a hot gas intake is avoided in all flow areas that run circumferentially around a cladding element.
- the object is achieved in terms of the combustion chamber according to the invention by a combustion chamber with a lining, which has a number of cladding elements, wherein between a first and a second cladding element, a flow region is formed, in which a flow barrier of the type mentioned above is used.
- This concept guarantees a reliable cooling of the holder and thus a secure and permanently stable mounting of the cladding elements.
- a hot gas intake into the flow area is avoided.
- Corrosion problems due to hot gas intake or other material loads in the vicinity of the flow region and behind the lining, in particular in the holder, are thus - in contrast to known flow barriers - eliminated.
- the aforementioned flow barrier design also has the advantage that larger tolerances in adjusting the column, i. the flow area between a first and a second cladding element are possible. In this way, the assembly time of the cladding elements is considerably reduced.
- the cooling air flowing out of a flow region between the lining elements is reduced or completely suppressed.
- the temperature gradients that form from the edges of a cladding element towards the cladding element center and the stresses associated therewith along the lateral extent of the cladding element are significantly reduced. Due to the reduced stresses, fewer and, if any, shorter cracks will form in a cladding element during operation.
- porous ceramic flow barriers are known.
- Such a known flow barrier is in the form of a double tube formed with an outer shell of high temperature resistant, ceramic Nextelgewebe and an inner shell of an Inconellgestrick, which is flexible in the composite and has sufficient length stability as well as the flow barrier on the spring force of the fabric holds in its axial position.
