Abstract

The fireproof cladding has several slabs (1) alongside and overlapping each other, with heat-resistant properties. The steel components (4) are fixed to the wall to which the cladding is to be applied. Each slab has at least one recess (2) to take one or more steel components. The transmission of operating forces between the wall and the slabs is thereby to a large extent avoided.

Description

Die Erfindung betrifft eine Feuerfestabkleidung, insbesondere für Müllverbrennungsanlagen, mit mehreren neben- und übereinander angeordneten Platten, die durch temperaturbeständige Erzeugnisse hinterfüllt werden, und mit Stahlteilen, die an der zu verkleidenden Wand befestigt sind, wobei jede Platte mindestens eine Ausnehmung aufweist, in die ein oder mehrere Stahlteile eingreifen.The invention relates to a refractory lining, in particular for Waste incineration plants, with several side by side and one above the other arranged panels that backfilled by temperature resistant products and with steel parts attached to the wall to be clad, wherein each plate has at least one recess in which one or engage several steel parts.

Kessel und Ofenräume, insbesondere Industrieöfen, bedürfen einer feuerfesten Wandkonstruktion, um den Kesselraum von den Rohraggregaten zu trennen. Hierzu erfolgt der Schutz der Stahlrohraggregate mittels vorgehängten Platten. Hierbei werden die zu schützenden Stahlrohraggregate großflächig mit den Rohrwandplatten verkleidet und die Zwischenräume verfüllt.Boilers and furnace rooms, in particular industrial furnaces, require a refractory Wall construction to separate the boiler room from the pipe aggregates. For this purpose, the protection of steel tube aggregates by means of suspended panels. Here are the steel pipe aggregates to be protected over a large area with the Covered pipe wall panels and filled the gaps.

Es sind zahlreiche Feuerfestabkleidungen bzw. Rohrwandverkleidungen bekannt, bei denen die Rohrwandplatten mittels Stahlteilen beigehalten werden. Eine Feuerfestabkleidung der eingangs genannten Art ist aus der EP 1 336 808 bekannt. Der Nachteil dieser bekannten Rohrwandverkleidung und anderer Rohrwandverkleidungen im Feuerfestbau besteht darin, dass die Hinterfüllmasse in alle Ausnehmungen und Öffnungen der Platten beim Hinterfüllen eindringt. Diese Hinterfüllmasse verbindet sich kraftschlüssig mit den Platten und mit den Stahlteilen, die die Platten hintergreifen und diese beihalten. Bei Betriebsbedingungen der Feuerfestabkleidung entstehen Verspannungen zwischen den Stahlteilen und den Platten, da das Verhalten der Platten und der Stahlteile bei Temperaturbeaufschlagung sehr unterschiedlich ist. Dadurch, dass sich die Hinterfüllmasse kraftschlüssig mit den Stahlteilen und den Platten verbunden hat, werden über die Hinterfüllmasse Kräfte übertragen, die durch den Betrieb bedingt sind und die zu Rissen in der Platte oder sogar zur Zerstörung der Platte führen können.There are numerous refractory linings or pipe wall linings known in which the tube wall plates are maintained by means of steel parts. A refractory lining of the aforementioned type is known from EP 1 336 808 known. The disadvantage of this known pipe wall paneling and others Rohrwandverkleidungen in refractory construction is that the Backing compound in all recesses and openings of the plates when Backfill penetrates. This Hinterfüllmasse connects with non-positively the plates and the steel parts behind the plates and these beihalten. At operating conditions of the refractory lining arise Tensions between the steel parts and the plates, as the behavior the plates and the steel parts at temperature exposure very much is different. The fact that the backfill with non-positively connected to the steel parts and the plates are over the Backfill transmitted forces that are due to the operation and the can lead to cracks in the plate or even destruction of the plate.

Die der vorliegenden Erfindung zu Grunde liegende Aufgabe besteht darin, diese Risse, bzw. die Zerstörung der Platten zu vermeiden.The underlying object of the present invention is to to avoid these cracks, or the destruction of the plates.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Übertragung von durch den Betrieb bedingten Kräften zwischen der zu verkleidenden Wand und den Platten weitestgehend vermieden wird.This object is achieved in that the transmission of operational forces between the wall to be covered and the plates is largely avoided.

Gemäß einer besonders bevorzugten Ausführungsform wird die Übertragung der genannten Kräfte dadurch weitestgehend vermieden, dass jedes Stahlteil und/oder jede Ausnehmung einer Platte mit einer Beschichtung versehen ist.According to a particularly preferred embodiment, the transmission The said forces thereby largely avoided that any steel part and / or each recess of a plate is provided with a coating.

Gemäß einer alternativen besonders bevorzugten Ausführungsform wird die Übertragung der genannten Kräfte dadurch weitestgehend vermieden, dass jede Ausnehmung einer Platte nach dem Aufhängen oder Aufstellen der Platte mit einer Masse verschlossen und/oder verfüllt wird.According to an alternative particularly preferred embodiment, the Transmission of said forces thereby largely avoided that each recess of a panel after hanging or placing the panel closed with a mass and / or filled.

Beide genannten Ausführungsformen können auch bei derselben Feuerfestabkleidung angewandt werden. Als Beschichtung bzw. Masse wird ein Material verwendet, das bei der dort im Betrieb herrschenden Temperatur schmilzt, verbrennt, erweicht, schwindet, schrumpft, sublimiert, verdampft oder verschwelt.Both mentioned embodiments can also with the same Refractory linings are applied. As a coating or mass is a Material used at the temperature prevailing in operation there melts, burns, softens, dwindles, shrinks, sublimates, evaporates or carbonized.

Im Betriebszustand der Feuerfestabkleidung ist bei der zuerst genannten Ausführungsform zwischen dem Stahlteil und dem Hinterfüllmasse-Platte-Verbund bzw. zwischen dem Stahlteil-Hinterfüllmasse-Verbund und der Platte ein Spalt entstanden, da die Beschichtung, mit der das Stahlteil bzw. die Ausnehmung der Platte versehen war, geschmolzen, verbrannt, erweicht, geschwunden, geschrumpft, sublimiert, verdampft oder verschwelt ist. Das Stahlteil hat nunmehr keine kraftschlüssige Verbindung mit der Platte, so dass die beschriebenen Risse in der Platte nicht mehr entstehen können. Vor dem Betriebszustand hat die Beschichtung, mit der das Stahlteil, bzw. die Ausnehmung versehen war, verhindert, dass die Hinterfüllmasse in dem betreffenden Bereichen sich mit dem Stahlteil bzw. der Platte verbinden konnte. Im Betriebszustand ist die Beschichtung geschmolzen, verbrannt, erweicht, geschwunden, geschrumpft, sublimiert, verdampft oder verschwelt und der Spalt an den betreffenden Bereichen entstanden. Die Übertragung der durch den Betrieb bedingten Kräfte zwischen der zu verkleidenden Wand, an der das Stahlteil befestigt ist, und den Platten wird hierdurch vermieden.In the operating condition of the refractory lining is at the first mentioned Embodiment between the steel part and the back mass-plate composite or between the steel part-Hinterfüllmasse composite and the plate a gap has arisen because the coating with which the steel part or the Recess of the plate was provided, melted, burned, softened, has disappeared, shrunk, sublimated, evaporated or siphoned off. The Steel part now has no frictional connection with the plate, so that The described cracks in the plate can no longer arise. Before the Operating state has the coating with which the steel part, or the Was provided recess, prevents the backfill in the areas could connect to the steel part or the plate. In operation, the coating is molten, burned, softened, dwindled, shrunk, sublimated, evaporated or siphoned off and the Gap occurred at the areas concerned. The transmission of the the operation conditional forces between the wall to be covered, at the Steel part is attached, and the plates is thereby avoided.

Gemäß der zweiten genannten Ausführungsform werden die Ausnehmungen der Platten nach dem Aufhängen oder Aufstellen der Platten mit einer Masse verschlossen und/oder verfüllt, die bei der dort im Betrieb herrschenden Temperatur schmilzt, verbrennt, erweicht, schwindet, schrumpft, sublimiert, verdampft oder verschwelt. Nach Montage der Platten der Feuerfestabkleidung wird die entstandene Plattenwand hinterfüllt. Durch die beschriebene Behandlung der Ausnehmungen kann diese Hinterfüllmasse nicht in die Ausnehmungen eindringen. Bei den bekannten Feuerfestabkleidungen, bei denen die Hinterfüllmasse in die Ausnehmungen eindringen konnte, hat sich gezeigt, dass dies zu Rissen oder sogar zu Zerstörungen der Platten führen konnte. Die Hinterfüllmasse verband sich während des Erhärtens mit den in die Ausnehmungen eingreifenden Stahlteile und bildete durch diese kraftschlüssige Verbindung eine Art "Anker", der im Betriebszustand durch die unterschiedlichen Eigenschaften des Stahlteils im Gegensatz zu der Platte bei Temperaturbeaufschlagung die Platten beschädigen oder sogar zerstören konnte. Dadurch, dass verhindert wird, dass die Hinterfüllmasse in die Ausnehmungen der Platten eindringen kann, wird eine Übertragung der durch den Betrieb bedingten Kräfte zwischen der zu verkleidenden Wand und den Platten vermieden. According to the second embodiment, the recesses become of the panels after hanging or placing the panels with a mass closed and / or filled, which prevailed in the operation there Temperature melts, burns, softens, dwindles, shrinks, sublimates, evaporated or blackened. After installation of the plates of the refractory lining The resulting panel wall is backfilled. By the described Treatment of the recesses may not be in the backfill Recesses penetrate. In the known refractory linings, at where the backfill could penetrate into the recesses, has become shown that this leads to cracks or even destruction of the plates could. The backfill compound joined during curing with in the Recesses engaging steel parts and formed by this non-positive Connection a kind of "anchor", which in the operating condition by the different properties of the steel part in contrast to the plate at Applying temperature will damage or even destroy the panels could. This prevents that the backfill material in the Recesses of the plates can penetrate, is a transmission of the operation conditional forces between the wall to be covered and the Plates avoided.

Vorteilhafterweise wird als Beschichtung organisches Material verwendet, wie z.B. Bitumen, Kunststoff, Wachs, Latex, Gummi, Papier oder Pappe.Advantageously, the coating used is organic material, such as e.g. Bitumen, plastic, wax, latex, rubber, paper or cardboard.

Vorteilhafterweise wird als Masse, mit der die Ausnehmungen der Platten während des Aufhängens oder Aufstellens der Platten verfüllt werden, ein Produkt geringer mechanischer Festigkeit verwendet, wie z.B. ausschäumender Kunststoff oder Keramik-Faser-Pasten oder -Schäume.Advantageously, as a mass with which the recesses of the plates be filled during hanging or erection of the plates, a Low mechanical strength product used, e.g. ausschäumender Plastic or ceramic fiber pastes or foams.

Vorteilhafterweise werden die Ausnehmungen der Platten verschlossen, so dass die Hinterfüllmasse nicht in die Ausnehmung eindringen kann. Es wird eine Barriere aufgebaut, so dass ein Hohlraum verbleibt. Als Barriere wird ein Material verwendet, das bei der dort im Betrieb herrschenden Temperatur schmilzt, verbrennt, erweicht, schwindet, schrumpft, sublimiert, verdampft oder verschwelt.Advantageously, the recesses of the plates are closed, so that the backfill mass can not penetrate into the recess. It will built a barrier so that a cavity remains. As a barrier is one Material used at the temperature prevailing in operation there melts, burns, softens, dwindles, shrinks, sublimates, evaporates or carbonized.

Vorteilhafterweise wird diese Barriere mittels eines Kunststoff-Formteiles ausgeführt. Dieses Formteil wird vorgeformt und in die Ausnehmung als Barriere eingesetzt.Advantageously, this barrier is by means of a plastic molding executed. This molding is preformed and into the recess as Barrier used.

Das Wesen der Erfindung besteht darin, eine kraftschlüssige Verbindung zwischen dem Stahlteil und der Platte zu vermeiden.The essence of the invention is a positive connection between the steel part and the plate to avoid.

Die Erfindung wird nun anhand der beigefügten Zeichnungen näher erläutert.The invention will now be explained in more detail with reference to the accompanying drawings.

    • Gemäß Fig. 1 weist die Platte 1 auf ihrer Rückseite eine Ausnehmung 2 auf. Diese Ausnehmung 2 ist mit der Beschichtung 3 versehen. Diese Platte 1 wird zur Fertigstellung der Feuerfestabkleidung auf das Stahlteil 4 gehängt. Das Stahlteil 4 ist als Haken ausgebildet, um die Ausnehmung 2 zu hintergreifen. Nach dem Aufhängen oder Aufstellen der Platte 1 wird die fertiggestellte Plattenwand hinterfüllt. In den Bereichen, an denen die Ausnehmung 2 mit der Beschichtung 3 versehen ist, kann sich die Hinterfüllmasse beim Hinterfüllen der Platten nicht kraftschlüssig mit der Platte verbinden. Im Betriebszustand der Anlage schmilzt, verbrennt, erweicht, schwindet, schrumpft, sublimiert, verdampft oder verschwelt die Beschichtung und es entsteht ein Spalt. Hierdurch wird verhindert, dass der Stahlteil-Hinterfüllmasse-Verbund kraftschlüssig mit der Platte verbunden ist. Die Übertragung der durch den Betrieb bedingten Kräfte zwischen der zu verkleidenden Wand und den Platten wird weitestgehend vermieden.According to FIG. 1, the plate 1 has a recess 2 on its rear side. This recess 2 is provided with the coating 3. This plate 1 is Hanging on the steel part 4 for the completion of the refractory lining. The Steel part 4 is formed as a hook to engage behind the recess 2. After hanging or setting up the plate 1 is the finished Back-filled panel wall. In the areas where the recess 2 with the Coating 3 is provided, the backfill may be when backfilling Do not connect the plates frictionally to the plate. In operation of the Plant melts, burns, softens, dwindles, shrinks, sublimates, the coating evaporates or fades and a gap is created. This will prevent the steel part backfill compound frictionally connected to the plate. The transmission of the by the Operation-related forces between the wall to be covered and the plates is largely avoided.

    Gemäß Fig. 2 weist die Platte 11 auf ihrer Rückseite die Ausnehmung 12 auf. Diese Platte 11 wird zur Fertigstellung der Feuerfestabkleidung auf das Stahlteil 14 gehängt. Dieses Stahlteil 14 ist als Haken ausgebildet, um die Ausnehmung 12 zu hintergreifen. Dieses Stahlteil 14 ist mit der Beschichtung 13 versehen. Nach dem Aufhängen und Aufstellen der Platte 1 wird die fertig gestellte Plattenwand hinterfüllt. Diese Hinterfüllmasse kann sich nicht kraftschlüssig mit dem Stahlteil 14 verbinden, da im Betriebszustand der Anlage die Beschichtung 13 schmilzt, verbrennt, erweicht, schwindet, schrumpft, sublimiert, verdampft oder verschwelt und ein Spalt entsteht. Hierdurch wird verhindert, dass sich das Stahlteil kraftschlüssig mit dem Hinterfüllmasse-Platte-Verbund verbindet. Die Übertragung der durch den Betrieb bedingten Kräfte zwischen der zu verkleidenden Wand und den Platten wird hierdurch weitestgehend vermieden. According to FIG. 2, the plate 11 has the recess 12 on its rear side. This plate 11 is used to complete the refractory lining on the steel part 14 hanged. This steel part 14 is formed as a hook to the recess 12 behind. This steel part 14 is provided with the coating 13. After hanging and setting up the plate 1 is the finished Back-filled panel wall. This backfill compound can not frictionally with connect the steel part 14, since in the operating condition of the system, the coating 13 melts, burns, softens, dwindles, shrinks, sublimates, evaporates or saps and a gap arises. This will prevent the Non-positively connected steel part with the backfill material-plate composite. The Transmission of the forces caused by the operation between the zu cladding wall and the plates is thereby largely avoided.

    Gemäß Fig. 3 ist die Platte 5 über das Stahlteil 6 mit dem Steg 7 der Rohrwand verbunden. Dieser Steg 7 verbindet die Rohre 8a und 8b. Das Stahlteil 6 befindet sich mit seinem äußeren Ende in der Ausnehmung 9 der Platte 5. Würde diese Rohrwandverkleidung nunmehr verfüllt, so würde die Hinterfüllmasse von oben in die Ausnehmung 9 eindringen und diese ausfüllen. Das Stahlteil 6 würde über diese Hinterfüllmasse mit der Platte 5 kraftschlüssig verbunden, so dass die durch den Betrieb bedingten Kräfte zwischen der zu verkleidenden Wand und den Platten übertragen würden. Die Ausnehmung 9 ist mit der Masse 10 verfüllt, so dass die Hinterfüllmasse nicht in die Ausnehmung 9 eindringen kann.According to Fig. 3, the plate 5 via the steel part 6 with the web 7 of the tube wall connected. This web 7 connects the tubes 8a and 8b. The steel part 6 is located with its outer end in the recess 9 of the plate. 5 Would this pipe wall paneling now filled, so would the Insert backfill from above into the recess 9 and fill it. The steel part 6 would frictionally over this Hinterfüllmasse with the plate 5 connected, so that the forces caused by the operation between the zu cladding wall and plates. The recess 9 is filled with the mass 10, so that the backfill mass is not in the recess 9 can penetrate.

    In Fig. 4 und 5 ist ein Längsschnitt durch eine Platte 5 dargestellt, bei der die Rohre 8 erkenntlich sind. Dieser Längsschnitt entspricht dem Schnitt durch die in Fig. 3 dargestellte Platte 5 längs des Stahlteiles 6. Das Stahlteil 6 ragt in die Ausnehmung 9 der Platte 5 ein. Man erkennt, dass die Ausnehmung 9 gemäß Fig. 4 und Fig. 5 nach oben offen ist. Nach dem Aufhängen oder Aufstellen der Platte 5 befindet sich das Stahlteil 6 teilweise in der Ausnehmung 9 und hält die Platte 5 bei.In Fig. 4 and 5, a longitudinal section through a plate 5 is shown, in which the 8 tubes are recognizable. This longitudinal section corresponds to the section through the Plate 5 shown in Fig. 3 along the steel part 6. The steel part 6 projects into the Recess 9 of the plate 5 a. It can be seen that the recess 9 according to Fig. 4 and Fig. 5 is open at the top. After hanging up or putting up the Plate 5 is the steel part 6 partially in the recess 9 and holds the Plate 5 at.

    Die Ausnehmung 9 wird nunmehr gemäß Fig.4 mit der Masse 10 verfüllt. Beim Hinterfüllen der Plattenwand mit den temperaturbeständigen Erzeugnissen können diese nicht in die Ausnehmungen der Platten eindringen. Bei der dort im Betrieb herrschenden Temperatur schmilzt, verbrennt, erweicht, schwindet, schrumpft, sublimiert, verdampft oder verschwelt diese Masse 10, so dass das Stahlteil 6 nicht kraftschlüssig mit der Platte 5 verbunden ist. Es entsteht vielmehr ein Hohlraum. Sofern die Hinterfüllmasse in die Ausnehmung 9 der Platte 5 eingedrungen wäre, hätte sie sich sowohl mit dem Stahlteil 6, das in die Ausnehmung 9 ragt, als auch mit der Platte 5 verbunden. Hierdurch wäre eine kraftschlüssige Verbindung des Stahlteils 6 mit der Platte 5 entstanden. Im Betriebszustand der Anlage hätten die unterschiedlichen Eigenschaften des Stahlteils 6 und der Platte 5 bei Temperaturbeaufschlagung zu Verspannungen geführt und möglicherweise zu Rissen oder Zerstörung der Platte 5.The recess 9 is now filled according to Figure 4 with the mass 10. At the Backfilling the panel wall with the temperature resistant products they can not penetrate into the recesses of the plates. When there in the Operation prevailing temperature melts, burns, softens, dwindles, shrinks, sublimates, evaporates or foams this mass 10, so that the Steel part 6 is not frictionally connected to the plate 5. It arises rather a cavity. If the Hinterfüllmasse in the recess 9 of Plate 5 would have penetrated, they would have both with the steel part 6, which in the Recess 9 protrudes, as well as connected to the plate 5. This would be one non-positive connection of the steel part 6 with the plate 5 emerged. in the Operating condition of the plant would have the different characteristics of the Steel part 6 and the plate 5 when subjected to temperature to tension led and possibly to tearing or destruction of the plate 5.

    Die Ausnehmung 9 ist gemäß Fig. 5 mit der Masse 15 und 16 verschlossen. Diese Masse 15 und 16 ist lediglich eine Schutzschicht, die als Barriere wirkt. Beispielsweise kann ein Kunststoff-Formteil verwendet werden, das die Ausnehmung 9 verschließt. Es wird somit verhindert, dass beim Hinterfüllen der Plattenwand die Hinterfüllmasse in die Ausnehmung 9 dringt. Bei der dort im Betrieb herrschenden Temperatur schmilzt, verbrennt, erweicht, schwindet, schrumpft, sublimiert, verdampft oder verschwelt diese Barriere und es verbleibt ein Hohlraum.The recess 9 is closed as shown in FIG. 5 with the mass 15 and 16. This mass 15 and 16 is merely a protective layer which acts as a barrier. For example, a plastic molding can be used which the Recess 9 closes. It is thus prevented when backfilling the Plate wall penetrates the backfill into the recess 9. When there in the Operation prevailing temperature melts, burns, softens, dwindles, Shrinks, sublimates, evaporates or foams this barrier and it remains a cavity.

    Bei allen dargestellten Ausführungsformen wird die Übertragung von durch den Betrieb bedingten Kräften zwischen der zu verkleidenden Wand und den Platten weitestgehend vermieden.In all the illustrated embodiments, the transmission of the through Operation conditional forces between the wall to be covered and the Plates largely avoided.
