Description
Die Erfindung bezieht sich auf eine Brennkammer einer Gasturbine mit einer äußeren Brennkammerwand und zumindest einer an dieser gelagerten Schindel, sowie mit einer Grundplatte.The invention relates to a combustion chamber of a gas turbine with an outer combustion chamber wall and at least one shingle mounted thereon, and with a base plate.
Aus dem Stand der Technik ist es bekannt, dass Brennkammerschindeln an einer tragenden Struktur der Brennkammeraußenwand, auch als Liner bezeichnet, befestigt sind. Die Brennkammerschindeln weisen eine große Anzahl an Effusionskühllöchern an der zur Brennkammer gerichteten Seite auf. Diese Effusionskühllöcher dienen dazu, die Schindel gegenüber den hohen Temperaturen in der Brennkammer zu kühlen. Weiterhin weist die Brennkammerschindel zumindest ein Mischluftloch auf, durch welches Luft aus dem die Brennkammer außen umgebenden Raum (Ringkanal/Annulus) in die Brennkammer geleitet wird, um die Verbrennungsgase abzukühlen und die Verbrennung abzumagern. Hierdurch erfolgt insbesondere eine Reduktion der NOx-Bildung in der Brennkammer. Zusätzlich zu der Kühlung durch die Effusionskühllöcher sind die Schindeln häufig mit einer keramischen Beschichtung versehen, welche als Dämmschicht gegen die hohen Temperaturen in der Brennkammer wirkt.It is known from the prior art that combustion chamber shingles are fastened to a supporting structure of the combustion chamber outer wall, also referred to as a liner. The combustion chamber shingles have a large number of effusion cooling holes on the side facing the combustion chamber. These effusion cooling holes serve to cool the shingle from the high temperatures in the combustion chamber. Furthermore, the combustion chamber shingle has at least one mixing air hole, through which air is passed from the space surrounding the combustion chamber (annular channel / annulus) into the combustion chamber in order to cool the combustion gases and to abase the combustion. In particular, this results in a reduction of NOx formation in the combustion chamber. In addition to the cooling by the Effusionskühllöcher the shingles are often provided with a ceramic coating, which acts as an insulating layer against the high temperatures in the combustion chamber.
Bei den aus dem Stand der Technik bekannten Lösungen erfolgt die Befestigung der Brennkammerschindel an der Brennkammeraußenwand mittels Gewindestiften. Diese sind integrale Bestandteile der meist als Gussteile ausgebildeten Schindeln und weisen ein Gewinde auf. Durch ein Loch in der Brennkammeraußenwand werden die Gewindestifte durchgeführt und von der Außenseite her mittels einer Mutter an der Brennkammeraußenwand fixiert.In the solutions known from the prior art, the fastening of the combustion chamber shingle to the combustion chamber outer wall takes place by means of threaded pins. These are integral parts of the shingles, which are usually designed as cast parts, and have a thread. Through a hole in the combustion chamber outer wall, the setscrews are performed and fixed from the outside by means of a nut on the combustion chamber outer wall.
Derartige Anordnungen sind beispielsweise aus der
Als nachteilig erweist es sich bei den bekannten Lösungen, dass durch die hohe thermische Belastung der Bolzen das Material der Bolzen kriecht. Durch das Kriechen des Materials wird die Vorspannung des Bolzens mittels der Mutter verringert. Dies führt dazu, dass die Bolzen locker werden und dass sich damit die Schindeln lösen können. Ein weiterer Nachteil liegt darin, dass es bei den gemäß dem Stand der Technik üblicherweise als Gusskonstruktionen ausgebildeten Schindeln nicht oder nur bedingt möglich ist, diese mittels eines alternativen Herstellungsverfahrens, nämlich mittels additiver Fertigung zu fertigen. Derartige additive Fertigungsverfahren sind beispielsweise Selective Laser Sintering, Direct Laser Depositioning oder Elektronenstrahlauftragsschweißen. Der Grund für die bedingte Herstellbarkeit der vorbekannten Konstruktionen liegt insbesondere darin, dass eine kostenintensive horizontale Fertigung gewählt werden muss. Alternativ hierzu ist eine aufwendige Unterkonstruktion zur Abstützung des Gewindestiftes erforderlich. Derartige Unterkonstruktionen sind materialintensiv und verlängern den Fertigungsprozess und müssen nach der Fertigung von der Schindel entfernt werden. Auch dies ist alles sehr kostenintensiv.It proves to be disadvantageous in the known solutions that creeps the material of the bolt by the high thermal load of the bolt. The creep of the material reduces the preload of the bolt by means of the nut. This will cause the bolts to loosen and allow the shingles to loosen. A further disadvantage is that with the shingles which are usually designed as cast constructions according to the prior art, it is not possible or only possible to a limited extent to manufacture them by means of an alternative production method, namely by means of additive manufacturing. Such additive manufacturing methods are, for example, selective laser sintering, direct laser depositioning or electron beam deposition welding. The reason for the conditional manufacturability of the previously known constructions is, in particular, that a cost-intensive horizontal production must be selected. Alternatively, a complex substructure for supporting the threaded pin is required. Such substructures are material intensive and extend the manufacturing process and must be removed after production of the shingle. This too is all very expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkammer einer Gasturbine zu schaffen, welche bei einfachem Aufbau und einfacher, kostengünstiger Herstellbarkeit, insbesondere mittels additiver Fertigungsverfahren, die Nachteile des Standes der Technik vermeidet und eine betriebssichere Konstruktion ermöglicht.The invention has for its object to provide a combustion chamber of a gas turbine, which avoids the disadvantages of the prior art with a simple structure and simple, cost manufacturability, in particular by means of additive manufacturing process and enables a reliable construction.
Erfindungsgemäß wird die Aufgabe durch die Merkmalskombination des Anspruchs 1 gelöst, die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.According to the invention the object is achieved by the combination of features of
Erfindungsgemäß ist somit vorgesehen, dass sich die Schindel über die gesamte Länge der Brennkammer erstreckt und an ihrem vorderen sowie an ihrem hinteren Ende jeweils in einer Nut gelagert ist. Die Nut ist am vorderen Ende an der Grundplatte der Brennkammer ausgebildet, während die Nut am hinteren Ende an der äußeren Brennkammerwand vorgesehen ist.According to the invention it is thus provided that the shingle extends over the entire length of the combustion chamber and is mounted at its front and at its rear end in each case in a groove. The groove is formed at the front end on the base plate of the combustion chamber, while the groove is provided at the rear end to the outer combustion chamber wall.
Durch die erfindungsgemäße Lösung ist es somit möglich, vollständig auf die Gewindebolzen zu verzichten. Vielmehr wird die Schindel als gesamtes Bauteil nur an ihrem vorderen und an ihrem hinteren Endbereich gelagert. Dies ermöglicht eine einfache, kostengünstige Herstellbarkeit der Schindel.The inventive solution, it is thus possible to dispense completely with the threaded bolt. Rather, the shingle is stored as an entire component only at its front and at its rear end. This allows a simple, inexpensive manufacture of the shingle.
Durch den Verzicht auf Gewindebolzen ist es möglich, die thermische Belastung der Schindel zu optimieren, da keine Materialanhäufungen, wie im Bereich der aus dem Stand der Technik bekannten Gewindebolzen, vorliegen.By dispensing with threaded bolts, it is possible to optimize the thermal load of the shingle, since there are no accumulations of material, as in the field of known from the prior art threaded bolt.
Die Herstellung der erfindungsgemäßen Brennkammer kann in einfacher Weise dadurch erfolgen, dass die Schindel mit ihrem hinteren Endbereich in die Nut der äußeren Brennkammerwand eingesteckt wird. Nachfolgend wird die äußere Brennkammerwand zusammen mit der Schindel an der Grundplatte montiert, indem der vordere Endbereich der Schindel in die Nut der Grundplatte eingeführt wird. Nachfolgend erfolgt ein Verschweißen der äußeren Brennkammerwand mit der Grundplatte.The production of the combustion chamber according to the invention can be carried out in a simple manner, that the shingle is inserted with its rear end portion in the groove of the outer combustion chamber wall. Subsequently, the outer combustion chamber wall is mounted together with the shingles on the base plate by the front end portion of the shingle is inserted into the groove of the base plate. Subsequently, the outer combustion chamber wall is welded to the base plate.
Erfindungsgemäß ist es möglich, die sich über die gesamte Länge der Brennkammer erstreckende Schindel beliebig zu gestalten. Insbesondere ist es möglich, in Umfangsrichtung mehrere Schindeln nebeneinander anzuordnen. Hierdurch ist ein einfacher Aufbau der erfindungsgemäßen Brennkammer möglich, welcher kostengünstig zu realisieren ist. Hierzu trägt auch bei, dass die erfindungsgemäße Schindel kostengünstig mittels additiver Verfahren in vertikaler Fertigung herstellt werden kann.According to the invention, it is possible to design the shingles extending over the entire length of the combustion chamber as desired. In particular, it is possible to arrange several shingles in the circumferential direction next to each other. As a result, a simple construction of the combustion chamber according to the invention is possible, which is inexpensive to implement. This also contributes to the fact that the shingle according to the invention can be produced inexpensively by means of additive processes in vertical production.
Erfindungsgemäß weist die Schindel somit an ihrem vorderen und ihrem hinteren Ende jeweils eine Feder auf, welche in die jeweilige Nut eingesteckt wird. Sowohl die Feder als auch die Nut können sich über den gesamten Umfang erstrecken oder auch segmentiert ausgebildet sein.According to the shingle thus has at its front and its rear end in each case a spring, which is inserted into the respective groove. Both the spring and the groove may extend over the entire circumference or be formed segmented.
