Description

Hitzeschildanordnung für eine Heißgas führende Komponente, insbesondere für Strukturteile von Gasturbinen, sowie Verfahren zum Herstellen einer derartigen AnordnungHeat shield arrangement for a component carrying hot gas, especially for structural parts of gas turbines, as well as processes for making such an arrangement

Die Erfindung betrifft eine Hitzeschildanordnung für eine Heißgas führende Komponente, insbesondere für Strukturteile von Gasturbinen. Sie betrifft weiterhin ein Verfahren zum Herstellen einer derartigen Anordnung.The invention relates to a heat shield arrangement for a Hot gas component, especially for structural parts of gas turbines. It also concerns a procedure for Manufacture of such an arrangement.

Die Anordnung enthält eine Mehrzahl von Hitzeschildelementen, die flächendeckend nebeneinander auf einer Tragstruktur angeordnet und mit dieser verankert sind.The arrangement contains a plurality of heat shield elements, which are arranged side by side on a supporting structure and are anchored to it.

Aufgrund der in Heißgasräumen herrschenden hohen Temperaturen besteht die Notwendigkeit, eine Tragstruktur, die heißem Gas ausgesetzt ist, zu schützen. Hierzu ist es beispielsweise möglich, den Heißgasraum mit Hitzeschildelementen auszukleiden, deren dem Heißgas zugewandte Fläche gekühlt wird.Due to the high temperatures in hot gas rooms there is a need for a support structure that is hot gas is exposed to protect. For this it is for example possible to line the hot gas space with heat shield elements, whose surface facing the hot gas is cooled.

In der EP 0 224 817 B1 ist eine Hitzeschildanordnung, insbesondere für Strukturteile von Gasturbinenanlagen, beschrieben, welche aus einer Anzahl von dreieckförmigen Hitzeschildelementen gebildet ist. Die Hitzeschildelemente sind nebeneinander jeweils unter Belassung eines Spalts auf einer Tragstruktur angeordnet und mit der Tragstruktur verschraubt.EP 0 224 817 B1 describes a heat shield arrangement, in particular for structural parts of gas turbine systems, described, which consists of a number of triangular heat shield elements is formed. The heat shield elements are side by side each leaving a gap on a supporting structure arranged and screwed to the support structure.

Nachteilig dabei ist, dass durch die vorher beschriebenen Spalte Heißgas vom Brennraum hindurchtreten und mit der Tragstruktur in Berührung kommen kann, so dass das Material der Tragstruktur infolge der entstehenden massiven Hitzeeinwirkung beschädigt werden kann.The disadvantage here is that the previously described Gap hot gas from the combustion chamber and with the support structure can come into contact, so that the material of the Support structure due to the resulting massive heat can be damaged.

In der deutschen Patentanmeldung mit dem Aktenzeichen 100 03 728.3 ist eine aus einer Anzahl von Hitzeschildelementen bestehende Hitzeschildanordnung gezeigt, bei welcher zwischen den Hitzeschildelementen Dichtelemente, vorzugsweise Riffelbleche, eingesetzt sind, um den Austritt von Heißgas aus dem Brennraum zu verhindern und die Tragstruktur zu schützen.In the German patent application with the file number 100 03 728.3 is one of a number of heat shield elements Heat shield arrangement shown, in which between the heat shield elements sealing elements, preferably checker plates, are used to prevent the escape of hot gas from the Prevent combustion chamber and protect the supporting structure.

Bei einer derartigen Anordnung ist nachteilig, dass beispielsweise das Einsetzen oder Lösen eines Hitzeschildelements einer derartigen Anordnung nicht unabhängig von dessen benachbarten Hitzeschildelementen stattfinden kann. Würde man z.B. beim Lösen einer derartigen Anordnung zu Reparaturzwecken beispielsweise nur die Verankerung eines Hitzeschildelements lösen und versuchen, das Hitzeschildelement zu entnehmen, so würde dieser Versuch scheitern, da mindestens vor dem Herausziehen des Hitzeschildelements aus der Anordnung die Dichtelemente zu den benachbarten Hitzeschildelementen manuell entfernt werden müssten, was jedoch ohne Lösen der benachbarten Hitzeschildelemente von der Tragstruktur oder zumindest Lockerung ihrer Verankerung und Bewegen in eine exzentrische Lage, so dass der Spalt zwischen den Hitzeschildelementen vergrößert ist, nicht möglich ist.The disadvantage of such an arrangement is that, for example the insertion or removal of a heat shield element such an arrangement is not independent of it neighboring heat shield elements can take place. You would e.g. when solving such an arrangement for repair purposes for example only the anchoring of a heat shield element loosen and try to remove the heat shield element, this attempt would fail because at least before Pulling out the heat shield element from the arrangement Sealing elements to the neighboring heat shield elements manually would have to be removed, but without loosening the neighboring one Heat shield elements from the support structure or at least Loosening their anchoring and moving into an eccentric Location so that the gap between the heat shield elements is enlarged, is not possible.

Auch beim Herstellen einer derartigen Anordnung können die Hitzeschildelemente nicht einfach unabhängig voneinander mit der Tragstruktur verankert werden, sondern es muss zunächst zwischen den Hitzeschildelementen jeweils ein größerer Spalt gebildet werden, das Dichtelement eingesetzt werden, der Spalt verkleinert werden und die Hitzeschildelemente schließlich mit der Tragstruktur verankert werden.Even when producing such an arrangement, the Heat shield elements are not easy to use independently of the supporting structure, but it must first a larger gap between the heat shield elements are formed, the sealing element can be used, the Gap are reduced and the heat shield elements finally be anchored to the supporting structure.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Hitzeschildanordnung für eine heißgasführende Struktur, insbesondere ein metallisches Bauteil einer Gasturbinenanlage oder Brennkammer, mit flächendeckend nebeneinander auf einer Tragstruktur verankerten Hitzeschildelementen sowie ein Verfahren zur Herstellung einer derartigen Hitzeschildanordnung anzugeben, welche insbesondere die beschriebenen Nachteile überwinden, flexibel einsetzbar und besonders leicht und schnell herstellbar sind. The invention is therefore based on the object of a heat shield arrangement for a structure carrying hot gas, in particular a metallic component of a gas turbine plant or Combustion chamber, with side by side on one Support structure anchored heat shield elements and a method for the production of such a heat shield arrangement specify which particular disadvantages described overcome, flexible use and particularly light and can be produced quickly.

Bezüglich der Anordnung wird die Aufgabe erfindungsgemäß durch eine Hitzeschildanordnung mit flächendeckend nebeneinander auf einer Tragstruktur verankerten Hitzeschildelementen gelöst, bei der mindestens zwei benachbarte Hitzeschildelemente jeweils mindestens eine seitliche, im Bereich des Randes ihrer dem Heißgas zugewandten Fläche angebrachte, Nut aufweisen, diese Hitzeschildelemente mittels mindestens eines in die Nut eingebrachten Dichtelements verbunden sind und bei welcher das Dichtelement als Dichtklappe ausgebildet ist, welche von einer ersten in eine zweite Position und umgekehrt bewegbar ist, wobei die erste Position eine geöffnete Lage ohne Dichtwirkung und die zweite Position eine geschlossene Lage mit Dichtwirkung ist.With regard to the arrangement, the object is achieved according to the invention thanks to a heat shield arrangement with side-by-side coverage heat shield elements anchored on a supporting structure solved, in which at least two neighboring Heat shield elements each have at least one lateral, in Area of the edge of their surface facing the hot gas attached, have groove, these heat shield elements by means at least one sealing element introduced into the groove are connected and in which the sealing element as Sealing flap is formed, which from a first into a second position and vice versa, the first Position one open position with no sealing effect and the second Position is a closed position with a sealing effect.

Bei einer erfindungsgemäßen Hitzeschildanordnung ist zum einen die Tragstruktur vor dem Kontakt mit aus dem Brennraum austretendem Heißgas durch das Dichtelement geschützt, welches Spalten zwischen den Hitzeschildelementen der Hitzeschildanordnung verschließt. Zum anderen ist eine erfindungsgemäße Hitzeschildanordnung wegen der besonderen Ausgestaltung des Dichtelements als Dichtklappe leicht herstellbar und lösbar, weil das Dichtelement beim Einsetzen oder Lösen von einer ersten in eine zweite Position bzw. umgekehrt bewegbar ist, so dass beim Herstellen der erfindungsgemäßen Anordnung das Dichtelement selbsttätig von seiner ersten Position (geöffnete Lage) in seine zweite Position (geschlossene Lage) bewegt wird und beim Lösen der erfindungsgemäßen Anordnung selbsttätig von seiner zweiten in seine erste Position bewegt wird. Das heißt, es ist nicht notwendig, das Dichtelement manuell in seine zweite (geschlossene) Position zu bringen bzw. aus seiner zweiten Position zu entfernen. Des Weiteren ist es möglich, ein einzelnes Hitzeschildelement zu entnehmen, ohne dabei die Verankerungen benachbarter Hitzeschildelemente lösen zu müssen. In a heat shield arrangement according to the invention, on the one hand the support structure before contact with the combustion chamber escaping hot gas is protected by the sealing element, which Gaps between the heat shield elements of the heat shield arrangement closes. On the other hand, it is an inventive one Heat shield arrangement because of the special design the sealing element as a sealing flap easy to manufacture and detachable because the sealing element when inserting or detaching a first in a second position or vice versa is so that when manufacturing the arrangement according to the invention the sealing element automatically from its first position (open Position) in its second position (closed position) is moved and when releasing the arrangement according to the invention automatically moves from its second to its first position becomes. That is, it is not necessary to manually seal the element to bring it into its second (closed) position or remove from its second position. Furthermore, it is possible to remove a single heat shield element without loosen the anchorings of adjacent heat shield elements to have to.

Mittels solcher Dichtelemente zwischen jeweils zwei benachbarten Hitzeschildelementen kann praktisch die ganze dem Heißgas ausgesetzte Fläche eines Heißgasraumes abgedeckt werden. Allerdings können an besonderen Positionen (z.B. am Ort von Messgeräten, Zuführungen oder Ableitungen von Gasen zum Heißgasraum etc.) Sonderkonstruktionen erforderlich sein, die Erfindung ist aber geeignet, zumindest die überwiegende Zahl der Hitzeschildelemente der Anordnung durch derartige Klappen gegeneinander abzudichten.By means of such sealing elements between two neighboring heat shield elements can be practically the whole surface of a hot gas space exposed to the hot gas become. However, in special positions (e.g. on Location of measuring devices, feeds or discharges of gases to the hot gas room etc.) special constructions may be required, however, the invention is suitable, at least the predominant one Number of heat shield elements of the arrangement by such To seal flaps against each other.

In vorteilhafter Ausgestaltung der Erfindung ist das Dichtelement mittels einer Bewegung eines Hitzeschildelements von der ersten in die zweite Position und umgekehrt bewegbar.In an advantageous embodiment of the invention, the sealing element by means of a movement of a heat shield element from the first to the second position and vice versa.

Beim Herstellen der erfindungsgemäßen Anordnung müssen die Dichtelemente nicht in einem separaten Arbeitsschritt in die erfindungsgemäße Anordnung eingebracht werden, sondern die Dichtelemente bewegen sich infolge der Bewegung eines einzusetzenden Hitzeschildelements selbsttätig in ihre zweite (geschlossene) Position, ohne dass dabei die Verankerungen von benachbarten Hitzeschildelementen mit der Tragstruktur gelöst werden muss.When manufacturing the arrangement according to the invention, the Sealing elements not in a separate step in the inventive arrangement are introduced, but the Sealing elements move as a result of the movement of an insert Heat shield element automatically in its second (closed) Position without losing the anchorages of neighboring heat shield elements solved with the support structure must become.

Vorteilhaft weist das Dichtelement einen im wesentlichen C-förmigen Querschnitt auf. Ein derartiger Querschnitt des Dichtelements ist besonders geeignet, da der auf diese Weise gebildete (Längs-)Schlitz besonders leicht zum Halten des Dichtelements in der ersten Position benutzt werden kann, indem beispielsweise der Schlitz des Dichtelements auf die Wand einer Nut gesteckt und so in der ersten Position gehalten wird.The sealing element advantageously has a substantially C-shaped Cross section on. Such a cross section of the Sealing element is particularly suitable because of this formed (longitudinal) slot particularly easy to hold the Sealing element can be used in the first position by for example the slot of the sealing element on the wall inserted in a groove and held in the first position becomes.

In einer vorteilhaften Ausgestaltung der Erfindung ist das Dichtelement ausgebildet als eine gebogene Platte. Das Dichtelement ist besonders leicht herstellbar, wenn er durch Biegen einer Platte hergestellt wird, da sehr viele Rohstoffe in Form von Platten erhältlich sind. In an advantageous embodiment of the invention Sealing element designed as a curved plate. The sealing element is particularly easy to manufacture when bent a plate is produced because a lot of raw materials in Form of plates are available.

Vorteilhaft besteht die Platte aus Blech.The plate is advantageously made of sheet metal.

Blech zeichnet sich durch eine hohe Widerstandsfähigkeit gegenüber Hitze aus, so dass Blech als Dichtelement bei der erfindungsgemäßen Hitzeschildanordnung besonders geeignet ist. Des Weiteren ist Blech leicht erhältlich, kostengünstig und besonders einfach verarbeitbar.Sheet metal is characterized by its high resistance to Heat out, so that sheet metal as a sealing element in the invention Heat shield arrangement is particularly suitable. Furthermore, sheet metal is readily available, inexpensive and particularly easy to process.

Die Erfindung führt weiterhin zu einem Verfahren zum Herstellen einer erfindungsgemäßen Hitzeschildanordnung mit folgenden Schritten:

  • 1. Ein erstes und ein zweites Hitzeschildelement werden unter Belassung eines Zwischenraums für ein drittes Hitzeschildelement auf der Tragstruktur verankert, so dass die Nut des ersten Hitzeschildelements der Nut des zweiten Hitzeschildelements gegenüberliegt.
  • 2. In die Nut des ersten und des zweiten Hitzeschildelements wird jeweils ein Dichtelement derart eingebracht, dass das Dichtelement in der ersten Position gehalten ist.
  • 3. Das dritte Hitzeschildelement, welches auf gegenüberliegenden Seiten jeweils eine Nut aufweist, wird in den Zwischenraum in Richtung der Tragstruktur hineinbewegt, wobei ein Dichtelement jeweils in eine dieser Nuten hineinragt.
  • 4. Durch die Bewegung des dritten Hitzeschildelements wird das Dichtelement in die zweite Position bewegt, und
  • 5. das dritte Hitzeschildelement wird auf der Tragstruktur verankert.
    • The invention further leads to a method for producing a heat shield arrangement according to the invention with the following steps:
  • 1. A first and a second heat shield element are anchored on the support structure, leaving a space for a third heat shield element, so that the groove of the first heat shield element lies opposite the groove of the second heat shield element.
  • 2. A sealing element is introduced into the groove of the first and the second heat shield element in such a way that the sealing element is held in the first position.
  • 3. The third heat shield element, which in each case has a groove on opposite sides, is moved into the intermediate space in the direction of the support structure, a sealing element in each case protruding into one of these grooves.
  • 4. The movement of the third heat shield element moves the sealing element into the second position, and
  • 5. the third heat shield element is anchored on the support structure.

    • Beim erfindungsgemäßen Verfahren ist es besonders vorteilhaft, dass die Dichtung zwischen den Hitzeschildelementen selbsttätig gebildet wird, ohne dass dabei ein manueller Arbeitsschritt notwendig ist: Das als Dichtklappe ausgebildete Dichtelement wird selbsttätig von seiner ersten (geöffneten) in seine zweite (geschlossene) Position bewegt, wobei es beispielsweise zusammengedrückt und in die Nut eingeführt wird, vorteilhaft in Art einer Drehbewegung. Das Zusammendrücken des Dichtelements verbessert die Dichtwirkung, wenn das derart "vorgespannte" Dichtelement schließlich eng an den Wänden der Nut anliegend in die Nut eingebracht ist und sichert darüber hinaus die zweite Position (geschlossene Lage) der Dichtklappe gegen Herausfallen aus der Nut.In the method according to the invention, it is particularly advantageous that the seal between the heat shield elements is automatically formed without a manual work step is necessary: The one designed as a sealing flap Sealing element is automatically from its first (opened) moved to its second (closed) position, for example compressed and inserted into the groove advantageous in the manner of a rotary movement. The squeeze of the sealing element improves the sealing effect when so "Prestressed" sealing element finally tight on the walls the groove is inserted into the groove and secures it the second position (closed position) of the Sealing flap to prevent it falling out of the groove.

    In Figur 1 ist eine erfindungsgemäße Hitzeschildanordnung 5 dargestellt.FIG. 1 shows a heat shield arrangement 5 according to the invention shown.

    Die Hitzeschildanordnung 5 schützt eine Tragstruktur 15 vor dem zerstörerischen Einfluss von Heißgas, welches in einer Brennkammer 10 gebildet ist.The heat shield arrangement 5 protects a support structure 15 the destructive influence of hot gas, which in a Combustion chamber 10 is formed.

    Die Hitzeschildanordnung 5 umfasst Hitzeschildelemente 20, welche flächendeckend nebeneinander auf der Tragstruktur 15 angeordnet und auf dieser mittels Befestigungselementen 35, beispielsweise Schraubverbindungen, verankert sind. The heat shield arrangement 5 comprises heat shield elements 20, which all over the side on the support structure 15 arranged and on this by means of fasteners 35, for example screw connections are anchored.

    Zwischen den einzelnen Hitzeschildelementen 20 befindet sich jeweils ein Spalt, durch welchen das in der Brennkammer gebildete Heißgas hindurchtreten und die Tragstruktur 15 angreifen könnte. Aus Gründen der Wärmedehnung der Hitzeschilde und auch einer guten Servicefreundlichkeit kann auf einen Spalt nicht verzichtet werden.Is located between the individual heat shield elements 20 each a gap through which the formed in the combustion chamber Pass hot gas through and attack the support structure 15 could. For reasons of thermal expansion of the heat shields and also a good service friendliness can be in one Gap can not be dispensed with.

    Um die Tragstruktur 15 vor Beschädigung oder Zerstörung zu bewahren, werden die vorher beschriebenen Spalte zwischen den Hitzeschildelementen 20 mittels Dichtelementen 30 abgedichtet.To support structure 15 from damage or destruction preserve, the previously described gaps between the Heat shield elements 20 sealed by means of sealing elements 30.

In die Nuten 25 jeweils benachbarter Hitzeschildelemente 20 ist ein Dichtelement 30 eingebracht.The heat shield elements 20 each have at least one lateral, in the area of the edge of the hot gas Surface attached, groove 25 on. In the grooves 25 each Adjacent heat shield elements 20 is a sealing element 30 brought in.

    Das Dichtelement 30 ist eine derart ausgebildete Dichtklappe, so dass diese von einer ersten in eine zweite Position bewegbar ist, wobei die erste Position eine geöffnete Lage ohne Dichtwirkung und die zweite Position eine geschlossene Lage mit Dichtwirkung ist. In der Figur 1 sind die Dichtelemente 30 in der zweiten Position dargestellt. Die Dichtelemente 30 weisen vorteilhaft einen im Wesentlichen C-förmigen Querschnitt auf. Hergestellt werden können die Dichtelemente 30 beispielsweise aus einer ebenen Platte, welche bevorzugt aus Blech besteht, und welche derart durch Biegen bearbeitet ist, dass sie einen C-förmigen Querschnitt aufweist. Eine solche C-förmige Dichtklappe weist eine Elastizität auf, die eine federnde Anlage an den Hitzeschildelementen und eine gute Dichtung ermöglicht.The sealing element 30 is a sealing flap designed in this way, so that it can be moved from a first to a second position is, the first position is an open position without Sealing effect and the second position a closed position with sealing effect. In Figure 1, the sealing elements 30 shown in the second position. The sealing elements 30 advantageously have a substantially C-shaped cross section on. The sealing elements 30 can be produced for example from a flat plate, which is preferably made of Sheet metal, and which is processed in this way by bending, that it has a C-shaped cross section. Such C-shaped sealing flap has an elasticity that a resilient contact with the heat shield elements and a good one Seal allows.

    Die in der Figur 1 nicht dargestellte erste Position des Dichtelements 30 kann beispielsweise dadurch gebildet sein, dass ein Dichtelement 30 mit seinem, infolge des C-förmigen Querschnitts ausgebildeten (Längs-)Schlitz an dem der Brennkammer 10 näher liegenden Rand der Nut 25 gehalten ist, in dem die genannte Wand in den Schlitz hineinragt (vgl. Figur 2b und 2c).The first position, not shown in FIG Sealing element 30 can be formed, for example, that a sealing element 30 with its, due to the C-shaped Cross-sectional (longitudinal) slot on the combustion chamber 10 closer edge of the groove 25 is held in where the wall protrudes into the slot (see figure 2b and 2c).

    Figur 2 zeigt die Schritte a) bis e) des erfindungsgemäßen Verfahrens.Figure 2 shows steps a) to e) of the invention Process.

    Im Schritt a werden ein erstes und ein zweites Hitzeschildelement 51, 52 unter Belassung eines Zwischenraums für ein dritte Hitzeschildelement 53 auf der Tragstruktur verankert, beispielsweise mittels jeweils einer Schraubverbindung 65, so dass die Nut des ersten Hitzeschildelements 51 der Nut des zweiten Hitzeschildelements 52 gegenüberliegt.In step a, a first and a second heat shield element 51, 52 leaving a space for one third heat shield element 53 anchored on the supporting structure, for example by means of a screw connection 65, see above that the groove of the first heat shield element 51 of the groove of the second heat shield element 52 is opposite.

    Das Dichtelement 80 ist ausgebildet als Hohlrohr, beispielsweise aus Blech, welches einen ovalen, im Wesentlichen C-förmigen, Querschnitt aufweist. Die Mantelfläche dieses Hohlrohres weist einen Schlitz 85 auf, welcher sich im Wesentlichen über die gesamte Länge des Dichtelements 80 erstreckt.The sealing element 80 is designed as a hollow tube, for example made of sheet metal, which has an oval, essentially C-shaped, Has cross section. The outer surface of this hollow tube has a slot 85 which is substantially extends over the entire length of the sealing element 80.

    Der Schlitz 85 ist besonders geeignet, das Dichtelement 80 in seiner ersten Position (geöffnete Lage ohne Dichtwirkung) zu halten, indem beispielsweise eine der Begrenzungswände einer Nut eines Hitzeschildelements in den Schlitz 85 eingeführt und das Dichtelement 80 auf diese Weise in der ersten Position gehalten ist (siehe hierzu beispielsweise auch Figur 2, Schritt b). Der über die Nut hinausragende Teil des Dichtelements 80 ist dann durch die Bewegung eines Hitzeschildelements erreichbar und das Dichtelement 80 dadurch in die zweite Position bewegbar.The slot 85 is particularly suitable, the sealing element 80 in its first position (open position without sealing effect) hold by, for example, one of the boundary walls of a Groove of a heat shield element inserted into the slot 85 and the sealing element 80 in this way in the first position is held (see, for example, also FIG. 2, Step b). The part of the sealing element protruding beyond the groove 80 is then due to the movement of a heat shield element achievable and thereby the sealing element 80 in the second position movable.

    Das Dichtelement 80 besteht bevorzugt aus Blech, welches beispielsweise durch Biegen in die Form gemäß Figur 3 gebracht worden ist.The sealing element 80 is preferably made of sheet metal, which for example brought into the shape according to FIG. 3 by bending has been.
