Definitions
- the invention relates to a flow barrier as an insert in a flow area 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 a gas turbine, is usually with a Covering provided to the housing parts of the combustion chamber carrying housing, also referred to as combustion chamber structure, to isolate and protect.
- the ruling in the combustion chamber Combustion chamber conditions in particular by strongly fluctuating and high temperatures, pressures and oxidizing effects of the hot gas are remote from the housing to keep.
- an area of the housing is too Protect in which the bracket is attached to the panel is.
- the thermal loads usually in a temperature range of 1350 ° C or above and can also, for. B. in the context of a quick closure subject to strong fluctuations.
- Such a thing Load is the metallic housing usually not suspendable. The case and the holder are thus also available a material fatigue progressing over time protect the material, the higher the material fatigue and greater temperature and pressure fluctuations in the combustion chamber occur.
- the Cladding usually has a number of cladding elements on. Be particularly advantageous from a Ceramic formed cladding element, also as heat shield (Ceramic Heat Shield, CHS) proven. A Another possibility is a cladding element To form a high temperature resistant metal alloy. On a metallic cladding element may be a ceramic Coating be applied.
- a trim element For compensation of different thermal expansion coefficients is used when assembling a trim element throughout Scope of the cladding element set a gap.
- the cladding elements of the panel are therefore at a distance assembled. This distance represents a flow area between a first and a second cladding element ready for disguise.
- the flow barrier should on the one hand due to thermal Changes varying width of the flow area Bear in mind and should be heat-resistant to another.
- porous ceramic gaskets are made of EP 1 302 723 A1.
- Such a porous ceramic seal Although it is resistant to high temperatures, it is still allowed do not come into direct contact with the hot gas. That I makes this contact in the combustion chamber difficult to avoid, must be such a porous ceramic seal of cooling air be flowed through to cool the seal itself and the Furthermore, the flow area before a hot gas intake too lock. Nevertheless, in porous ceramic gaskets the mentioned type overheating occurred.
- the essential Reason is that one in each case of a real operation a combustion chamber sufficient flow through the porous ceramic Seal with cooling air difficult to guarantee is.
- the above use of cooling air to block the flow area and to cool one high temperature resistant flow barrier has the disadvantage that the Cooling air at the edges of the cladding element in the combustion chamber occurs and in this way quite significant temperature gradients along the lateral extent of a trim element arise.
- So has a cladding element Application of the usual concept explained here on his Edge due to the cooling air outlet a much lower Temperature on than at its center facing the combustion chamber.
- the invention begins, whose task it is to provide a flow barrier that is heat resistant and at the same time in a shape changeable, in its dimensions varying flow range can be used and which is as simple as possible.
- An advanced one Object of the present invention in terms of Cladding and the combustion chamber with such a flow barrier This is related to the cooling air account of the problems identified.
- the object according to the invention through a flow barrier for use in a Flow region between a first and a second cladding element solved a lining of a combustion chamber, wherein the flow barrier is a high temperature resistant ceramic body and a spring element.
- the combustion chamber of Combustion chamber prevents the hot gas intake.
- the H conquergaseinzugshememmung is by the supporting spring force of the spring element is still improved.
- the spring element even by the high temperature resistant ceramic body protected against hot gas access.
- the spring element So it only needs lower requirements for high-temperature strength to satisfy in comparison to the ceramic body. All behind the panel element and the high temperature resistant Ceramic body lying parts, including the Spring element, can also be effectively through Cool cooling air.
- the invention has recognized that a hitherto conventional porous ceramic flow barrier to a number of secondary problems leads, according to the concept explained here, a total of high temperature resistant flow barrier can be avoided.
- a high temperature resistant ceramic body as part of the flow barrier guarantees 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 another one depending on the purpose high temperature resistant ceramics are used.
- the adequate Hot gas resistance of the high temperature resistant ceramic body especially the most safe and reliable Effect of the flow barrier in comparison to previously usual porous ceramic flow barriers result.
- the combination of high-temperature resistant proves Ceramic body and the spring element to a flow barrier as very adaptable in use in a strongly deformed state as a result of temperature fluctuations and distance variable flow area between the first and the second trim element.
- the parts, d. H. the high temperature resistant ceramic body and the spring element, the flow barrier can be easily manufacture and thus produce cost.
- the invention thus goes, in departure from the known porous ceramic flow barrier, from the new and in his Effect surprising consideration that compared to a porous ceramic flow barrier explained here Flow barrier with a relatively rigid high temperature resistant Ceramic body nevertheless a reliable seal the flow area leads. In combination with the Spring element proves the flow barrier according to the new concept namely as sufficiently variable within the shape variable flow area.
- the high temperature resistant ceramic body and the spring element advantageously have an elongated extent, wherein the ceramic body along a bearing surface on the spring element rests and the bearing surface along the elongated extent is aligned.
- Such elongated spring elements can be put together especially easy and in a flow area of a lining of a combustion chamber assemble. Its elongated extension bears the elongated Expansion of the flow area between a first and a second cladding element of the panel invoice.
- the support surface is curved towards the spring element.
- the spring element has on his the Pad side facing a trough and the high temperature resistant Ceramic body on its the bearing surface facing side on a bulge.
- the bulge of the ceramic body and the trough of the spring element are expediently adapted to each other, so that the ceramic body in Spring element comes to rest safely and against a lateral Slipping is secured in the trough.
- the spring element expediently holding means on which the location of the high temperature resistant ceramic body along the elongated extension ensures.
- the ceramic body is also in an axial direction, d. H. in a direction of elongated extension, against Secured slipping.
- a holding means is a stop or a sufficiently rough design of the bearing surface between the spring element and the ceramic body particularly suitable.
- the spring element at least along a fraction of the elongated extent in the form of a pressure-loaded spring according to the principle of action a plate spring formed. That is, the spring element is, except for its elongated extension (instead of a round in a diaphragm spring), formed in principle like a plate spring and in principle is based on the same mechanism of action like a diaphragm spring.
- the spring element along another fraction of the elongated one Extension is designed in the form of a bare pad.
- the spring element at least along a fraction of the elongated extent in the form of a compression-stressed, resiliently yielding Full body formed.
- a pressure-stressed to the solid body gives a springy effect. It can be about uniform solid material or a composition or a conglomerate of different materials.
- One Cross section through the solid body advantageously has a shape, which is similar to the shape of a recumbent eight.
- the task in terms of cladding is according to the invention through a lining for a combustion chamber with a number detached from cladding elements, wherein between a first and second cladding element, a flow area is formed in which is a flow barrier of the type mentioned above is used.
- one or more Flow barriers used in the flow area are that the flow area through the one or more Flow barriers is completely sealed. To this In fact, a hot gas intake will be in the flow area completely prevented.
- the object is according to the invention in terms of the combustion chamber solved by a combustion chamber with a fairing, which is a Number of cladding elements, wherein between a a first and a second cladding element a flow area is formed, in which a flow barrier of the above type is used.
- the said formation of the flow barrier also has the Advantage that greater tolerances in adjusting the column, i.e. 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.
- CHS Ceramic Heat Shields
- flow barrier Seal is the from a flow area between the cladding elements outgoing cooling air reduced or completely suppressed. Consequently decrease from the edges of a trim element towards the lining element center forming temperature gradient and the associated stresses along the lateral Extension of the cladding element in quite considerable Dimensions. Due to the reduced voltages form in the Operation less and, if any, shorter cracks in one Cladding element off.
- porous ceramic flow barriers are known.
- Such a known flow barrier is in shape a double tube formed with an outer shell high temperature resistant, ceramic Nextel fabric and one Inner shell of an Inconellgestrick, which in the composite is flexible and has sufficient length stability than also the flow barrier via the spring force of the knitted fabric holds in its axial position.
- the ends of the flow barrier are sewn with a new thread.
- Such a tubular formed porous ceramic Flow barrier is high temperature resistant, but may do not come into direct contact with the hot gas. That I makes this contact in the combustion chamber difficult to avoid, the flow barrier must be traversed by cooling air. However, a sufficient flow with cooling air can be not in every phase of a real operation of a gas turbine guarantee, so that a hitherto usual flow barrier Overheating may have. Furthermore, an insufficient leads Flow of cooling air causes the bracket a panel element not sufficient with cooling air is supplied and overheated where the flow barrier failed. Overheating of the known flow barrier in Shape of a flexible knit leads to loss of spring force of the knitted fabric and aggravates the above Situation.
