Description

Feuerfeste RohrwandverkleidungRefractory pipe wall cladding
Die vorliegende Erfindung bezieht sich auf eine feuerfeste Rohrwandverkleidung mit einer Vielzahl von neben- und übereinander angeordneten feuerfesten Platten, wie sie im Oberbegriff des unabhängigen Patentanspruchs 1 definiert ist.The present invention relates to a refractory pipe wall cladding with a plurality of refractory plates arranged side by side and one above the other, as defined in the preamble of independent claim 1.
Feuerfeste Rohrwandverkleidungen werden beispielsweise eingesetzt, um Rohrwande in Feuerraumen von Kehrnchtverbrennungs- anlagen vor Korrosion durch Rauchgase zu schützen. Die Rohr- wände und Rohrwandverkleidungen werden in den heutigen Kehr- richtverbrennungsanlagen oftmals Temperaturen von über 1000°C ausgesetzt und erfahren auch bei geeigneter Materialwahl aufgrund der grossen Temperaturunterschiede der einzelnen Betriebszustande Dehnungen und Kontraktionen. Die Temperaturun- terschiede sind bei den Rohrwandverkleidungen im allgemeinen grosser als bei den Rohrwanden, was bei der Materialwahl und/oder Ausgestaltung der Rohrwandverkleidungen berücksichtigt werden muss, damit die Rohrwandverkleidungen nicht durch grossere Dehnungen und Kontraktionen als die Rohrwande zer- stört werden.Refractory pipe wall cladding is used, for example, to protect pipe walls in the fire rooms of Kehrncht incineration plants from corrosion by flue gases. The pipe walls and pipe wall cladding are often exposed to temperatures of over 1000 ° C in today's waste incineration plants and experience expansions and contractions due to the large temperature differences of the individual operating conditions even when the material is selected appropriately. The temperature differences are generally greater for the pipe wall claddings than for the pipe walls, which must be taken into account when choosing the material and / or the design of the pipe wall claddings, so that the pipe wall claddings are not destroyed by greater expansions and contractions than the pipe walls.
Die Wahl eines geeigneten Materials für die Rohrwandverkleidung ermöglicht es, dass die Rohrwandverkleidung für jeden Betriebszustand auf die Rohrwand abgestimmt ist. Für Rohrwande aus Stahl haben sich SiC-Rohrwandverkleidungen bewahrt, wobei der SiC-Gehalt sehr unterschiedlich sein kann. In der Praxis werden SiC-Massen oder SiC-Platten mit einem SiC-Gehalt von 30% - 90% eingesetzt.The selection of a suitable material for the pipe wall cladding enables the pipe wall cladding to be matched to the pipe wall for every operating state. For pipe walls made of steel, SiC pipe wall claddings have been preserved, although the SiC content can be very different. In practice, SiC materials or SiC plates with an SiC content of 30% - 90% are used.
Es sind verschiedene feuerfeste Rohrwandverkleidungen bekannt, die eine Vielzahl von neben- und übereinander angeordneten feuerfesten keramischen SiC-Platten umfassen, die mit je mindestens einer Plattenhalterung an der zu schützenden Rohrwand befestigt sind. Der SiC-Gehalt der keramischen Platten van- iert; weit verbreitet ist aber die Verwendung von sogenannten SiC 90-Platten, d.h. Platten mit einem SiC-Gehalt von ca. 90%.Various refractory pipe wall claddings are known which comprise a multiplicity of refractory ceramic SiC plates arranged next to and one above the other, each of which is fastened to the pipe wall to be protected with at least one plate holder. The SiC content of the ceramic plates iert; However, the use of so-called SiC 90 plates, ie plates with an SiC content of approximately 90%, is widespread.
Beim Rohrwandplattensystem JUSYS RWS 4.2 der Firma Jünger + Gräter GmbH, Schwandorf/DE, wird jede Platte einerseits von einem an der Rohrwand angeschweissten Stift getragen und in Wandrichtung zurückgehalten und ist anderseits mittels eines SiC-Mörtels mit der Rohrwand verklebt.With the JUSYS RWS 4.2 pipe wall plate system from Jünger + Gräter GmbH, Schwandorf / DE, each plate is held on the one hand by a pin welded to the pipe wall and retained in the direction of the wall, and is also glued to the pipe wall using SiC mortar.
Beim Rohrwandplattensystem Carborundum der Firma Saint-Gobain Industriekeramik GmbH, Köln/DE, wird jede Platte an einer von der Rohrwand schräg nach oben verlaufenden stiftartigen Plat- tenhalterung eingehängt.With the tube wall plate system Carborundum from Saint-Gobain Industriekeramik GmbH, Cologne / DE, each plate is hung on a pin-like plate holder that runs diagonally upwards from the tube wall.
Ein bei beiden Plattensystemen auftretendes Problem ist die Beschädigungsanfälligkeit der Rohrwandverkleidung bei zu raschem Anfahren der Kehrrichtverbrennungsanlage, da Rohrwandverkleidung und Rohrwand verschieden schnell erhitzt werden. Weil die Bewegungsfreiheit einer einzelnen Platte durch die Plattenhalterung und die benachbarten Platten eingeschränkt ist, kann die im Vergleich zur Rohrwand schnellere Dehnung der Platte bei zu raschem Anfahren nicht kompensiert werden und die Platte und/oder benachbarte Platten wird bzw. werden herausgebrochen oder ausgehängt .A problem that occurs with both plate systems is the susceptibility to damage of the pipe wall cladding when the waste incineration plant starts up too quickly, since the pipe wall cladding and the pipe wall are heated at different speeds. Because the freedom of movement of an individual plate is restricted by the plate holder and the neighboring plates, the faster expansion of the plate compared to the pipe wall cannot be compensated for if the plate is started too quickly, and the plate and / or neighboring plates are or are broken out or hung out.
Aus der US-A-3 850 146 ist eine feuerfeste Rohrwandverkleidung bekannt, bei der eine Vielzahl von neben- und übereinander angeordneten feuerfesten Platten mit Plattenhalterungen an einer Rohrwand mit durch Stege verbundenen Rohren gehalten sind, wo- bei die Plattenhalterungen keine Tragfunktion haben. Mehrere übereinander angeordnete Platten sind von Konsolen getragen, die an die Rohre angeschweisst sind. Die rohrwandseitige Befestigung der Plattenhalterungen erfolgt über die Konsolen.From US-A-3 850 146 a refractory pipe wall cladding is known, in which a multiplicity of refractory plates arranged next to and above one another with plate holders are held on a pipe wall with pipes connected by webs, whereby the plate holders have no supporting function. Several plates arranged one above the other are supported by brackets that are welded to the pipes. The plate brackets are attached to the pipe wall using the brackets.
Dadurch, dass die Plattenhalterungen keine Tragfunktion haben, können sie die Platten vertikal verschiebbar an der Rohrwand halten. Problematisch ist bei dieser Rohrwandverkleidung jedoch, dass die Konsolen an die Rohre, d.h. an den Druckkörper angeschweisst werden müssen. Schweissungen am Druckkörper müssen in vielen Staaten von einem anerkannten Fachmann oder einer Behörde überprüft werden. Auch nachtragliche Änderungen sind deswegen relativ aufwendig.Because the plate brackets have no supporting function, they can be moved vertically on the pipe wall hold. The problem with this pipe wall cladding, however, is that the brackets have to be welded to the pipes, ie to the pressure element. In many countries, welds on the pressure body must be checked by a recognized specialist or an authority. Subsequent changes are therefore relatively complex.
Angesichts der Nachteile der bisher bekannten Rohrwandplattensysteme liegt der Erfindung die Aufgabe zugrunde, eine feuer- feste Rohrwandverkleidung der eingangs erwähnten Art zu schaffen, bei der unterschiedliche Dehnungen und Kontraktionen der feuerfesten Platten und der verkleideten Rohrwand sowohl in vertikaler als auch in horizontaler Richtung ohne Beschädigung der Rohrwandverkleidung aufgefangen werden können und die mon- tiert werden kann ohne Schweissungen an den Rohren.In view of the disadvantages of the previously known pipe wall plate systems, the invention has for its object to provide a refractory pipe wall cladding of the type mentioned, in which different expansions and contractions of the refractory plates and the clad pipe wall in both the vertical and horizontal directions without damaging the Pipe wall cladding can be caught and can be installed without welding on the pipes.
Diese Aufgabe wird gelöst durch die erfindungsgemasse feuerfeste Rohrwandverkleidung, wie sie im unabhängigen Patentanspruch 1 definiert ist. Patentanspruch 9 bezieht sich auf eine erfin- dungsgemass feuerfest verkleidete Wand und Patentanspruch 11 auf ein erfindungsgemasses Verfahren zum feuerfesten Verkleiden einer Rohrwand. Bevorzugte Ausfuhrungsvarianten ergeben sich aus den abhangigen Patentansprüchen.This object is achieved by the refractory pipe wall cladding according to the invention as defined in independent claim 1. Claim 9 relates to a fire-resistant clad wall and claim 11 to a method according to the invention for fireproof cladding a pipe wall. Preferred embodiment variants result from the dependent patent claims.
Das Wesen der Erfindung besteht darin, dass bei einer feuerfesten Rohrwandverkleidung mit einer Vielzahl von neben- und übereinander angeordneten feuerfesten Platten mit je mindestens einer Plattenhalterung, die dazu bestimmt ist bzw. sind, die Platte an einer Rohrwand mit durch Stege verbundenen Rohren zu halten, wobei die Plattenhalterungen keineThe essence of the invention is that in the case of a refractory pipe wall cladding with a multiplicity of refractory plates arranged next to and above one another, each with at least one plate holder, which is or are intended to hold the plate on a pipe wall with pipes connected by webs, the plate brackets none
Tragfunktion haben und die Platten von mindestens einer von den Plattenhalterungen unabhängigen Konsole getragen sind, die Plattenhalterungen und die Konsole bzw. Konsolen ausgebildet sind, um an die Stege der Rohrwand befestigt zu werden. Dadurch, dass die Rohrwandverkleidung an die Stege und nicht an die Rohre befestigt wird, wird der Druckkörper nicht beeinträchtigt. Kontrollen von einem anerkannten Fachmann oder einer Behörde sind daher überflüssig. Ein weiterer Vorteil besteht darin, dass die Plattenhalterungen und die Konsolen durch ihre Verbindung mit den Stegen gekühlt sind. Da die Platten nicht starr an der Rohrwand befestigt sind, sind ausserdem bei geeignetem, beabstandetem Anordnen der Platten Dehnungen und Kontraktionen derselben durch Verschieben in vertikaler und horizontaler Richtung auffangbar.Have a supporting function and the plates are carried by at least one bracket independent of the plate holders, the plate holders and the bracket or brackets are designed to be attached to the webs of the tube wall. The fact that the pipe wall cladding is fastened to the webs and not to the pipes does not affect the pressure body. Checks by a recognized specialist or an authority are therefore superfluous. Another advantage is that the plate brackets and the brackets are cooled by their connection to the webs. Since the plates are not rigidly attached to the tube wall, expansion and contraction of the plates can also be absorbed by moving them in the vertical and horizontal directions if the plates are suitably spaced apart.
Bei einer bevorzugten Ausführungsvariante sind mehrere übereinander angeordnete Platten direkt oder über die darunter angeordnete Platte bzw. Platten von einer einzigen Konsole getragen, die bei an einer Rohrwand montierter Rohrwandverkleidung an der Rohrwand befestigt, insbesondere ange- schweisst, ist. Die von der Konsole getragenen Platten können sich dann nach oben ausdehnen und verschieben. Die auf diese Weise im Vergleich zum bisherigen Stand der Technik erhöhte Plattenbeweglichkeit ermöglicht ein beschädigungsloses Auffangen von grösseren Dehnungen und Kontraktionen der Rohrwandverkleidung als die bekannten Rohrwandplattensysteme.In a preferred embodiment variant, a plurality of plates arranged one above the other are carried directly or via the plate or plates arranged below them by a single bracket which is fastened, in particular welded, to the pipe wall when the pipe wall cladding is mounted on a pipe wall. The panels carried by the console can then expand and move upwards. The increased plate mobility compared to the prior art in this way enables greater expansion and contraction of the pipe wall cladding to be absorbed without damage than the known pipe wall plate systems.

Mounted on the webs 22, in particular shot with a pistol, are two plate holders 11 belonging to the pipe wall cladding in the form of screws. The refractory plate 1 has two T-shaped slots 16 which extend from the upper edge 12 to the lower edge 13 and can be inserted from above via the plate holders 11. The rear side of the plate 1 facing the tube wall is provided with three recesses in the form of cylindrical segments which extend over the entire height, so that the
Platte 1 über weite Bereiche einen gleichmässigen Abstand zur Rohrwand aufweist. Idealerweise betragt der Abstand ca. 5 mm. Er kann durch Justieren der Plattenhalterungen 11 vor dem Einfahren der Platte 1 eingestellt werden. Nötigenfalls müssen die Platte 1 wieder entfernt und die Plattenhalterungen 11 nachjustiert werden.Plate 1 has a uniform distance from the pipe wall over wide areas. The ideal distance is approx. 5 mm. It can be adjusted by adjusting the plate brackets 11 before inserting the plate 1. If necessary, the plate 1 must be removed again and the plate holders 11 readjusted.
Der obere Rand 12 und der untere Rand 13 der Platte 1 sind über die Plattendicke komplementär abgestuft. Sind zwei derartige Platten 1 übereinander angeordnet, so gewährleisten die sich teilweise überdeckenden Rander, dass die Platten in einem gewissen Ausmass voneinander weg und aufeinander zu bewegbar sind, ohne dass zwischen den beiden Platten eine Fuge entsteht, die ein geradliniges Durchstro- men von Gas erlaubt. Der seitliche Rand 14 der Platte 1 weist eine Feder 141 und der seitliche Rand 15 eine komplementäre Nut 151 auf, was bei zwei solch nebeneinander angeordneten Platten 1 sicher- stellt, dass d e Platten m einem gewissen Ausmass voneinander weg und aufeinander zu bewegbar sind, ohne dass zwischen den beiden Platten eine Fuge entsteht, die ein geradliniges Durchströmen von Gas erlaubt.The upper edge 12 and the lower edge 13 of the plate 1 are graded complementarily over the plate thickness. If two such plates 1 are arranged one above the other, the partially overlapping edges ensure that the plates can be moved away from one another and towards one another to a certain extent without a gap being created between the two plates, which allows gas to flow in a straight line . The side edge 14 of the plate 1 has a tongue 141 and the side edge 15 has a complementary groove 151, which, in the case of two plates 1 arranged next to one another, ensures that the plates can be moved to a certain extent away from and towards one another without that a gap is created between the two plates, which allows gas to flow straight through.
Selbstverständlich können auch der obere Rand 12 und der untere Rand 13 mit Nut und Feder versehen oder die seitlichen Rander 14 und 15 komplementär abgestuft sein. Es sind auch andere, z.B. kurvige Randformen denkbar, vorausgesetzt, dass sie ein geradliniges Durchströmen von Gas zwi- sehen zwei neben- oder übereinander angeordneten Platten für alle in der Praxis auftretenden gegenseitigen Positionen verhindern.Of course, the upper edge 12 and the lower edge 13 can be provided with tongue and groove or the side edges 14 and 15 can be complementarily graded. There are also others, e.g. Curved edge shapes are conceivable, provided that they prevent gas flowing straight through between two plates arranged side by side or one above the other for all mutual positions that occur in practice.
Zwischen den gegenüberliegenden Randern 12 und 13 bzw. 14 und 15 zweier neben- oder übereinander angeordneter Platten 1 wird jeweils ein feuerfester Keramikfaserstreifen angeordnet, der die Fugen zwischen den Platten 1 abdichtet, so dass kein Rauchgas durch die Rohrwandverkleidung hindurch zur Rohrwand 2 gelangen kann. Feuerfeste Keramikfaserstrei- fen, die bis 1350°C hitzebestandig sind, sind auf dem Markt erhältlich.Between the opposite edges 12 and 13 or 14 and 15 of two plates 1 arranged one above the other or one above the other, a fire-resistant ceramic fiber strip is arranged, which seals the joints between the plates 1, so that no flue gas can pass through the pipe wall cladding to the pipe wall 2. Refractory ceramic fiber strips that are heat resistant up to 1350 ° C are available on the market.
Der Raum zwischen der Rohrwand 2 und der Platte 1 ist mit hier nicht dargestelltem SiC-Fliessmortel gefüllt, der die Platte 1 mit der Rohrwand 2 zusätzlich verklebt. Wird die Platte 1 bewegt, so bilden sich Risse im Mörtel oder der Mörtel lost sich von der Rohrwand 2 oder der Platte 1. Dies hat aber keine negativen Auswirkungen auf die Dichtheit der Rohrwandverkleidung, da diese durch die Platten 1 und die Keramikfaserstreifen sichergestellt wird. Der SiC-Mörtel wird nach der Positionierung der Platten 1 im richtigen Abstand zur Rohrwand 2 als Fliessmörtel von oben her zwischen die Platten 1 und die Rohrwand 2 einge- lassen und fliesst auch in die Schlitze 16. Um die Beweglichkeit der Platten 1 zu gewährleisten, werden daher die Plattenhalterungen 11 zuvor mit einem feuerfesten Schaum umgeben, der elastisch bleibt.The space between the tube wall 2 and the plate 1 is filled with SiC flow mortar, not shown here, which additionally glues the plate 1 to the tube wall 2. If the plate 1 is moved, cracks form in the mortar or the mortar detaches from the pipe wall 2 or the plate 1. However, this has no negative effects on the tightness of the pipe wall cladding, since this is ensured by the plates 1 and the ceramic fiber strips. After the plates 1 have been positioned at the correct distance from the pipe wall 2, the SiC mortar is let in from above between the plates 1 and the pipe wall 2 and also flows into the slots 16. In order to ensure the mobility of the plates 1, Therefore, the plate holders 11 are previously surrounded with a refractory foam that remains elastic.
Der SiC-Fliessmörtel hat vorzugsweise einen SiC-Gehalt zwischen 30% und 90%, insbesondere zwischen 40% und 60%, und eine Porosität kleiner 20%, insbesondere zwischen 13% und 17%. Als besonders geeignet hat sich ein SiC-Fliessmörtel erwiesen, der 58% SiC, 13% Si02, 26% A1203, 0,2% Fe203 und 1,5% CaO enthält.The SiC flow mortar preferably has an SiC content between 30% and 90%, in particular between 40% and 60%, and a porosity less than 20%, in particular between 13% and 17%. An SiC flow mortar which contains 58% SiC, 13% Si0 2 , 26% A1 2 0 3 , 0.2% Fe 2 0 3 and 1.5% CaO has proven to be particularly suitable.
Die Plattenhalterungen 11 selbst sind aus hitzebeständigem Stahl, z.B. Stahl Nr. 310 nach AISI-Norm oder Werkstoff Nr. 1.4845 nach DIN 17440.The plate holders 11 themselves are made of heat-resistant steel, e.g. Steel no.310 according to the AISI standard or material no.1.4845 according to DIN 17440.

Die Rohrwandverkleidung ist hier an einer Rohrwand 2' angebracht, bei der jeweils neben zwei aneinanderliegenden Rohren 21' und 23' ein Steg 22' angeordnet ist. Vorteilhafter- weise weisen die Platten 1 entsprechend angepasste Rückseiten mit teilzylinderförmigen Aussparungen auf.The pipe wall cladding is attached here to a pipe wall 2 ', in which a web 22' is arranged in each case next to two pipes 21 'and 23' lying against one another. The plates 1 advantageously have correspondingly adapted rear sides with partially cylindrical cutouts.
Zum Tragen der Platten 1 sind Konsolen 3 an die Rohrwand 2' angeschweisst . Die Konsolen 3 bestehen jeweils aus zwei vertikal angeordneten Stützplatten 31, die je an einen Steg 22' geschweisst sind, und einer horizontal angeordneten Tragplatte 32, die auf die beiden Stützplatten 31 geschweisst ist. Stützplatten 31 und Tragplatten 32 sind aus hitzebeständigem Stahl, z.B. Stahl Nr. 310 nach AISI-Norm oder Werkstoff Nr. 1.4845 nach DIN 17440. Jede Konsole 3 trägt eine direkt auf der Tragplatte 32 aufliegende Platte 1 sowie indirekt die zwischen dieser Platte 1 und der in vertikaler Richtung nächsten Konsole 3 ange- ordneten Platten 1, die jeweils mit ihrem unteren Rand 13 auf dem oberen Rand 12 der darunterliegenden Platte 1 aufliegen .To carry the plates 1, brackets 3 are welded to the tube wall 2 '. The brackets 3 each consist of two vertically arranged support plates 31, which are each welded to a web 22 ', and a horizontally arranged support plate 32, which is welded to the two support plates 31. Support plates 31 and support plates 32 are made of heat-resistant steel, for example steel No. 310 according to the AISI standard or material No. 1.4845 according to DIN 17440. Each console 3 carries a plate 1 lying directly on the support plate 32 and indirectly the plates 1 arranged between this plate 1 and the next console 3 in the vertical direction, each with its lower edge 13 on the upper edge 12 of the plate 1 below lie on.
Zwischen dem unteren, abgestuften Rand 13 einer direkt auf einer Konsole 3 aufliegenden Platte 1 und dem oberen, abgestuften Rand 12 der darunterliegenden Platte 1 sind aufgrund der Abstufung zwei Fugen vorhanden, die der unteren Platte 1 einen Bewegungsspielraum lassen, aber untereinander keinen direkten Kontakt haben, so dass die Rohrwandver- kleidung in allen beim Betrieb auftretenden gegenseitigen Plattenstellungen dicht ist.Between the lower, stepped edge 13 of a plate 1 lying directly on a bracket 3 and the upper, stepped edge 12 of the underlying plate 1, there are two joints due to the gradation, which allow the lower plate 1 freedom of movement, but have no direct contact with one another , so that the pipe wall cladding is sealed in all mutual plate positions that occur during operation.
Die Plattenhalterungen 11 sind in den Fig. 4 bis 6 nur angedeutet, aber nicht vollständig gezeichnet.The plate holders 11 are only indicated in FIGS. 4 to 6, but not completely drawn.
Zu den vorbeschriebenen Rohrwandverkleidungen sind weitere konstruktive Variationen realisierbar. Hier ausdrücklich erwähnt sei noch, dass die Schlitze 16 nicht unbedingt T-förmig sein müssen. Es sind auch andere Formen, wie z.B. ein Teil eines Zylinders, denkbar. Wichtig ist nur, dass zwischen einem breiteren Bereich im Platteninnern und dem rückseitigen Plattenrand ein schmalerer Bereich vorhanden ist, so dass die Platten 1 mittels der Plattenhalterungen 11 an der Rohrwand 2 gehalten werden können. E In addition to the pipe wall cladding described above, other design variations are possible. It should be expressly mentioned here that the slots 16 do not necessarily have to be T-shaped. There are other forms, such as part of a cylinder, conceivable. It is only important that there is a narrower area between a wider area in the inside of the plate and the rear edge of the plate, so that the plates 1 can be held on the tube wall 2 by means of the plate holders 11. e
