- a heat shield for the combustion chamber of a gas turbine with a support structure which has a hot gas side and a cold gas side and an edge connecting the hot and cold gas side.
- the support structure have grooves.
- the holders are pushed into these grooves. The holders are thus secured in the support structure and thereby partially clasp the heat shield on its flanks.
- the cross-sectional profile is designed so that the end of the holder, which is made with the largest width, is held in the groove.
- the slightly narrower executed spring range of the holder can from the bottom of the groove for applying the Holding bias to be bent.
- the retaining elements in this case remain displaceable in the groove, but are held positively perpendicular to the support structure surface.
- the heat shield assembly has at least two adjacent heat shields, namely a first heat shield and a second heat shield, each having a hot gas side and an opposite cold gas side.
- the heat shields have an adjacent side wall connecting the hot gas side and the cold gas side, wherein each one of the hot gas side and cold gas side spaced engagement pocket is introduced into the adjacent side wall.
- the one side wall of the first heat shield starting from the engagement pocket toward the hot gas side, has a projection, wherein the projection has at least one projection side and an adjoining projection front edge having.
- the second heat shield starting from the engaging pocket towards the hot gas side, has a recess which is substantially complementary to the projection, the recess having at least one recess side and an adjoining recess trailing edge, which are arranged starting from the engagement pocket between recess and projection is formed to the hot gas side open gap.
- the projection side as well as the recess side has a slope with respect to the respective cold gas side.
- the heat shield arrangement according to the invention reduces the entry of hot gas from the hot gas side.
- Such an arrangement may also be referred to as a labyrinth seal.
- the gap and the underlying metallic components are protected by the sealing effect against hot gas intake and additionally shielded against radiant heat. Due to the slope also remains the blocking or cooling air, which can be passed through the gap, longer in the engaging pocket as well as longer in the heat shields themselves, so that a better cooling of the components can be achieved. Thus, cooling air can be saved.
- overheating and scaling, in particular the metallic components in the heat shield assembly can be prevented.
- damage cases and downtimes can be avoided.
- such a slope can be better compensated for the movements of the supporting structure, which lead to movements of the heat shields.
- the inventive heat shield arrangement with the overlapping of the heat shields results in passive safety of the heat shields.
- the gap between the heat shields for guiding cooling air is provided.
- the projection side has a different pitch than the recess side.
- a different pitch an increase or decrease in the velocity of the cooling air flowing through the gap can be effected.

- the second heat shield 2b comprises a hot gas side 3b and a cold gas side 4b.
- the direction from the hot gas side 3a to the cold gas side 4a is referred to as a radial direction.
- the heat shields 2a, 2b comprise at least two mutually adjacent side walls 6a, 6b.
- the first heat shield 2 a now has an engagement pocket 5 a at a distance from the cold gas side 4 a and hot gas side 3 a.
- this engaging pocket 5a can be considered as a groove which does not extend over the entire axial length of the side wall 6a, wherein the axial direction of the side wall 6a is transverse to the radial direction.
- the second heat shield 2b also has a same engaging pocket 5b.
- Holders 10a, 10b with gripping arms now engage the cold gas side 4a, 4b in the engaging pocket 5a, 5b.
- the holders 10a, 10b with gripping arms cover a part of the side wall 6a, 6b. With these holders 10a, 10b, the heat shield 2a, 2b can be attached to a support structure (not shown).
- the holders 10a, 10b are made of metal and therefore must be cooled.
- the second heat shield 2b starting from the engagement pocket 5b toward the hot gas side 3b, has a recess which is complementary to the projection.
- the recess has at least one recess side 7b and an adjoining recess trailing edge 8b.
- the projection side 7a and the projection leading edge 8a of the first heat shield 2a are therefore formed so as to be complementary to the recess side 7b as well as the recess trailing edge 8b, thereby forming a gap 9 open to the hot gas side 3a, 3b between the recess and the projection.
- the projection side 7a and the recess side 7b have a pitch with respect to the cold gas side 4a, 4b.
- the heat shields 2a and 2b overlap.
- the overlap acts as a seal against hot gas intake.
- this overlap also acts as a protection against thermal radiation on the metallic components. Hot gas can now only with difficulty penetrate into the column 9. A hot gas intake from the cold gas side 4a, 4b is made much more difficult by the projection and the recess.
- Cooling air is led to cool the holders 10a, 10b from the cold gas side 4a, 4b through the engaging pocket 5a, 5b and then through the gap 9 into the combustion chamber.
- cooling air can be saved.
- an overlap of the heat shields 2a, 2b increases the passive safety, for example against falling out of fragments in case of breakage of the heat shields 2a, 2b.
- the slope also causes the cooling air to remain longer in the engaging pockets 5a, 5b than, for example, without such a slope, that is, when such a projection side 7a is nearly perpendicular to a projection leading edge 8b.
- movements of the support structure (not shown), which lead to movements of the heat shields 2a, 2b, better compensated by such a slope, as if the Projection side 7a and the recess side 7b have no such slope.
- the recess side 7b may have a different pitch than the projection side 7a.
- the projection side 7a may have a smaller pitch with respect to the cold gas side 4a, 4b than the recess side 7b.
- the beginning of the projection side 7a facing the engagement pocket 5a forms a larger gap 9 with the beginning of the recess side 7b facing the engagement pocket 5b than is the case at the end.
- the cooling air velocity increases as it flows along the gap 9.
- the hot gas inflow into the gap 9 can be prevented.
- a greater slope of the projection side 7a to the recess side 7b with respect to the cold gas side 4a, 4b is possible.

Description
Die Erfindung betrifft eine Hitzeschildanordnung mit zumindest zwei benachbarten Hitzeschilden, nämlich eines ersten Hitzeschilds und eines zweiten Hitzeschilds, welche jeweils eine Heißgasseite und eine gegenüberliegende Kaltgasseite aufweisen, wobei die Hitzschilde eine die Heißgasseite und die Kaltgasseite verbindende benachbarte Seitenwand aufweisen, wobei jeweils eine von der Heißgasseite und Kaltgasseite beabstandete Eingreiftasche in die benachbarte Seitenwand eingebracht ist.The invention relates to a heat shield assembly having at least two adjacent heat shields, namely a first heat shield and a second heat shield, each having a hot gas side and an opposite cold gas side, the heat shields having a hot gas side and the cold gas side connecting adjacent side wall, wherein each one of the hot gas side and cold gas side spaced engaging pocket is inserted in the adjacent side wall.
Die Wände von Hochtemperaturgasreaktoren, wie zum Beispiel von unter Druck betriebenen Brennkammern, die in Gasturbinen zum Einsatz kommen, müssen mit geeigneten Abschirmungen ihrer tragenden Struktur gegen hohe thermische Belastungen wie beispielsweise Heißgas geschützt werden. Hierfür bieten sich neben metallischen auch keramische Materialien an, die sich durch eine hohe Temperaturbeständigkeit, Korrosionsbeständigkeit und niedrige Wärmeleitfähigkeit auszeichnen.The walls of high temperature gas reactors, such as pressurized combustors used in gas turbines, must be shielded against high thermal stresses, such as hot gas, with suitable shields of their supporting structure. In addition to metallic ones, ceramic materials offering high temperature resistance, corrosion resistance and low thermal conductivity are suitable for this purpose.
Ein solches Hitzeschild geht aus der
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Hitzeschildanordnung anzugeben, welche die obigen Nachteile vermeidet.It is therefore the object of the present invention to provide a heat shield assembly which avoids the above disadvantages.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Hitzeschildanordnung nach Anspruch 1.According to the invention this object is achieved by a heat shield assembly according to claim 1.
Die Hitzeschildanordnung weist zumindest zwei benachbarte Hitzeschilde auf, nämlich ein erstes Hitzeschild und ein zweites Hitzeschild, welche jeweils eine Heißgasseite und eine gegenüberliegende Kaltgasseite aufweisen. Die Hitzschilde weisen eine die Heißgasseite und die Kaltgasseite verbindende benachbarte Seitenwand auf, wobei jeweils eine von der Heißgasseite und Kaltgasseite beabstandete Eingreiftasche in die benachbarte Seitenwand eingebracht ist.The heat shield assembly has at least two adjacent heat shields, namely a first heat shield and a second heat shield, each having a hot gas side and an opposite cold gas side. The heat shields have an adjacent side wall connecting the hot gas side and the cold gas side, wherein each one of the hot gas side and cold gas side spaced engagement pocket is introduced into the adjacent side wall.
Erfindungsgemäß weist die eine Seitenwand des ersten Hitzschildes ausgehend von der Eingreiftasche in Richtung Heißgasseite einen Vorsprung auf, wobei der Vorsprung zumindest eine Vorsprungsseite und eine sich daran anschließende Vorsprungsvorderkante aufweist. Das zweite Hitzeschild weist ausgehend von der Eingreiftasche in Richtung Heißgasseite eine zu dem Vorsprung im Wesentlichen komplementäre Aussparung auf, wobei die Aussparung zumindest eine Aussparungsseite und eine sich daran anschließende Aussparungshinterkante aufweist, welche so angeordnet sind, dass ausgehend von der Eingreiftasche zwischen Aussparung und Vorsprung ein zur Heißgasseite offener Spalt ausgebildet ist. Die Vorsprungsseite als auch die Aussparungsseite weist eine Steigung in Bezug auf die jeweilige Kaltgasseite auf.According to the invention, the one side wall of the first heat shield, starting from the engagement pocket toward the hot gas side, has a projection, wherein the projection has at least one projection side and an adjoining projection front edge having. The second heat shield, starting from the engaging pocket towards the hot gas side, has a recess which is substantially complementary to the projection, the recess having at least one recess side and an adjoining recess trailing edge, which are arranged starting from the engagement pocket between recess and projection is formed to the hot gas side open gap. The projection side as well as the recess side has a slope with respect to the respective cold gas side.
Durch die erfindungsgemäße Hitzeschildanordnung wird der Eintritt von Heißgas von der Heißgasseite reduziert. Eine solche Anordnung kann auch als Labyrinthdichtung bezeichnet werden. Dabei werden der Spalt sowie die darunter liegenden metallischen Bauteile durch die dichtende Wirkung gegen Heißgaseinzug geschützt und zusätzlich gegen Strahlungswärme abgeschirmt. Durch die Steigung verbleibt zudem die Sperr- oder Kühlluft, welche durch den Spalt hindurchgeführt werden kann, länger in der Eingreiftasche als auch länger in den Hitzschilden selbst, so dass eine bessere Kühlung der Bauteile erzielt werden kann. Somit kann Kühlluft gespart werden. Somit kann Überhitzung und Verzunderung, insbesondere der metallischen Bauteile in der Hitzeschildanordnung verhindert werden. Somit können Schadensfälle und Stillstandzeiten vermieden werden. Zudem kann eine solche Steigung die Bewegungen der Tragstruktur, die zu Bewegungen der Hitzeschilde führen, besser kompensiert werden. Durch die erfindungsgemäße Hitzeschildanordnung mit der Überschneidung der Hitzeschilde ergibt sich eine passive Sicherheit der Hitzschilde.The heat shield arrangement according to the invention reduces the entry of hot gas from the hot gas side. Such an arrangement may also be referred to as a labyrinth seal. The gap and the underlying metallic components are protected by the sealing effect against hot gas intake and additionally shielded against radiant heat. Due to the slope also remains the blocking or cooling air, which can be passed through the gap, longer in the engaging pocket as well as longer in the heat shields themselves, so that a better cooling of the components can be achieved. Thus, cooling air can be saved. Thus, overheating and scaling, in particular the metallic components in the heat shield assembly can be prevented. Thus, damage cases and downtimes can be avoided. In addition, such a slope can be better compensated for the movements of the supporting structure, which lead to movements of the heat shields. The inventive heat shield arrangement with the overlapping of the heat shields results in passive safety of the heat shields.
In bevorzugter Ausgestaltung ist der Spalt zwischen den Hitzeschilden zur Führung von Kühlluft vorgesehen.In a preferred embodiment, the gap between the heat shields for guiding cooling air is provided.
Durch den Spalt wird Kühlluft durchgeführt, welche von der Kaltgasseite der Hitzschilde zugeführt wird. Somit werden die Hitzschilde als auch die Heißgasseite der Hitzeschilde gekühlt.Through the gap cooling air is performed, which is supplied from the cold gas side of the heat shields. Thus, the heat shields as well as the hot gas side of the heat shields are cooled.
Bevorzugt weist die Vorsprungsseite eine andere Steigung auf als die Aussparungsseite. Durch eine andere Steigung kann eine Erhöhung oder Verminderung der Geschwindigkeit der durchströmenden Kühlluft durch den Spalt bewirkt werden. Somit kann Kühlluft an besonders kritischen Stellen beispielsweise länger verweilen. Auch kann der Heißgaseinzug weiter vermindert werden.Preferably, the projection side has a different pitch than the recess side. By a different pitch, an increase or decrease in the velocity of the cooling air flowing through the gap can be effected. Thus, cooling air can stay longer at particularly critical points, for example. Also, the hot gas intake can be further reduced.

FIG. 1 shows a heat shield assembly according to the invention.
Die Aussparungsseite 7b kann eine andere Steigung aufweisen als die Vorsprungsseite 7a. Insbesondere kann die Vorsprungsseite 7a eine kleinerer Steigung in Bezug auf die Kaltgasseite 4a, 4b aufweisen, als die Aussparungsseite 7b. Somit bildet der Anfang der Vorsprungseite 7a, welche zu der Eingreiftasche 5a weist, einen größeren Spalt 9 mit dem Anfang der Aussparungsseite 7b, welche zu der Eingreiftasche 5b weist, aus, als dies am Ende der Fall ist. Dadurch erhöht sich die Kühlluftgeschwindigkeit während sie den Spalt 9 entlang strömt. Dadurch kann zusätzlich die Heißgaseinströmung in den Spalt 9 verhindert werden. Aber auch eine größere Steigung der Vorsprungsseite 7a zur Aussparungsseite 7b in Bezug auf die Kaltgasseite 4a, 4b ist möglich.The
