Description

Die Erfindung betrifft Feuerfestabkleidungen, insbesondere für Müllverbrennungsanlagen, mit mehreren neben- und übereinander angeordneten Platten und mit Stahlteilen, die an der zu verkleidenden Wand oder Decke befestigt sind, wobei die Rückseite jeder Platte zumindest im oberen Bereich eine Nut aufweist, in die ein Stahlteil eingreift.The invention relates to refractory linings, in particular for waste incineration plants, with a plurality of juxtaposed and stacked plates and with steel parts which are fastened to the wall or ceiling to be covered, wherein the back of each plate has a groove at least in the upper region, in which engages a steel part ,

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 vergossen.Boilers and furnace rooms, in particular industrial furnaces, require a refractory wall construction in order to separate the boiler room from the pipe aggregates. For this purpose, the protection of steel tube aggregates by means of suspended panels. Here, the steel pipe units to be protected are covered over a large area with the pipe wall panels and potted the spaces.

Es sind mehrere Feuerfestabkleidungen bekannt, bei denen die Rohrwandplatten mittels Stahlteilen gehalten werden, wobei derartige Stahlteile zusätzlich eine Tragfunktion für die Platten ausüben.There are several known refractory linings in which the tube wall panels are held by steel members, with such steel members additionally providing a support function for the panels.

Ferner sind Feuerfestabkleidungen bekannt, bei denen außer den Stahlteilen zusätzliche Trageelemente vorgesehen sind, deren Nachteil darin besteht, dass die Vorbereitung der Rohrwand zum Anbringen der Platten zeitaufwendig ist, da sowohl die Stahlteile als auch die Tragelemente angebracht werden müssen.Furthermore, refractory linings are known in which additional support elements are provided in addition to the steel parts, the disadvantage is that the preparation of the pipe wall for attaching the plates is time-consuming, since both the steel parts and the support elements must be attached.

Aus der DE-PS 40 07 662 ist eine Verankerungsvorrichtung für Stahlrohraggregate abdeckende Steinplatten bekannt, die an den die Rohre verbindenden Rohrflossen angeordnet sind und an denen die Rohrwandplatten befestigt werden können. Nachteilig bei dieser bekannten Verankerungsvorrichtung ist es, dass diese Verankerungsvorrichtung in den Fugen zwischen den Rohrwandplatten angeordnet sind.From the DE-PS 40 07 662 An anchoring device for steel pipe aggregates covering stone slabs is known, which are arranged on the pipe fins connecting the pipes and on which the pipe wall plates can be attached. A disadvantage of this known anchoring device is that these anchoring device are arranged in the joints between the tube wall plates.

Aus der WO 97/09577 A1 ist eine Feuerfestabkleidung gemäß den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen bekannt. Bei dieser bekannten Feuerfestabkleidung werden die Platten mittels Schrauben an der Rohrwand befestigt. Jede Platte wird von außen festgeschraubt, wobei eine Bohrung an der Oberseite der Platte vorhanden ist, durch die die Schraube festgeschraubt werden kann. Der Nachteil einer derartigen Bohrung, auch wenn sie sehr klein ist, besteht darin, dass Gase eindringen können, die die zu schützende Rohrwand beschädigen, bzw. zur Korrosion an bestimmten Stellen dieser Rohrwand führen können. Ein weiterer Nachteil einer derartigen Befestigungsanordnung besteht darin, dass das Stahlteil und insbesondere die Schrauben, die von den korrosiven Gasen umgeben sind, selbst korrodieren.From the WO 97/09577 A1 is a refractory lining according to the features specified in the preamble of claim 1 known. In this known refractory lining the plates are fastened by screws to the pipe wall. Each plate is screwed from the outside, with a hole on the top of the plate, through which the screw can be screwed. The disadvantage of such a bore, even if it is very small, is that gases can penetrate, which damage the pipe wall to be protected, or can lead to corrosion at certain points of the pipe wall. Another disadvantage of such a fastening arrangement is that the steel part and in particular the screws, which are surrounded by the corrosive gases, corrode themselves.

Bei dieser bekannten Feuerfestabkleidung werden die Rohrwände an den entsprechenden Stellen mit Mörtel versehen. Anschließend werden die Platten aufgebracht und mittels Schrauben befestigt. Ein derartiges Verputzen der Rohrwände und Befestigen der einzelnen Platten ist sehr zeitaufwendig und damit sehr teuer.In this known Feuerfestabkleidung the pipe walls are provided at the appropriate places with mortar. Then the plates are applied and fastened by screws. Such plastering of the pipe walls and attaching the individual plates is very time consuming and therefore very expensive.

Die der vorliegenden Erfindung zugrundeliegende Aufgabe besteht darin Feuerfestabkleidungen vorzuschlagen, die derart ausgebildet sind, dass die Platten schnell neben- und übereinander angeordnet werden können und dass die Wände oder Decken vor ungewünschten äußeren Einflüssen geschützt angeordnet sind.The object underlying the present invention is to propose refractory linings, which are designed such that the plates can be arranged next to and above each other quickly and that the walls or ceilings are arranged protected from undesired external influences.

Diese Aufgabe wird erfindungsgemäß durch die in den Ansprüchen vorgeschlagenen Feuerfestabkleidungen gelöst.This object is achieved by the proposed in the claims refractory linings.

Gemäß Anspruch 1 besteht die Feuerfestabkleidung aus mehreren neben- und übereinander angeordneten Platten. Um die Platten bei der Montage an den zu verkleidenden Wänden oder Decken zu halten, ist auf der Rückseite jeder Platte zumindest im oberen Bereich eine Nut angeordnet, in die ein Stahlteil einführbar ist. Diese Stahlteile sind verdeckt an der zu verkleidenden Wand oder Decke eingebaut.According to claim 1, the refractory lining of several juxtaposed and stacked plates. In order to hold the plates during assembly to the walls or ceilings to be covered, a groove is arranged on the back of each plate at least in the upper region into which a steel part is inserted. These steel parts are installed concealed on the wall or ceiling to be clad.

Die Platten werden über der Wand oder Decke angebracht, wobei das Stahlteil in die Nut eingeführt wird. Die Platte wird durch das Stahlteil daran gehindert, horizontal zu kippen. Sie wird jedoch nicht derartig an dem Stahlteil befestigt, das ein Bewegen der Platte nach oben oder unten nicht mehr möglich wäre. Der Kopf des Stahlteiles kann frei nach oben oder unten in der Nut gleiten.The panels are placed over the wall or ceiling, with the steel part inserted into the groove. The plate is prevented by the steel part from tilting horizontally. However, it is not attached to the steel part in such a way that it would no longer be possible to move the plate up or down. The head of the steel part can slide freely up or down in the groove.

Bei der erfindungsgemäßen Feuerfestabkleidung einer zu schützenden Rohrwand werden an den Rohrflossen Stahlteile an den gewünschten Stellen befestigt, vorzugsweise geschweißt. Anschließend wird die unterste Reihe der Platten vor die Wand gestellt, wobei jeweils ein Stahlteil in die Nut auf der Rückseite jeder Platte eingeführt wird.In the refractory lining according to the invention of a pipe wall to be protected steel parts are attached to the pipe fins at the desired locations, preferably welded. Subsequently, the bottom row of plates is placed in front of the wall, with one steel part each being inserted into the groove on the back of each plate.

Jedes Stahltteil dient lediglich dazu, die Platte an einem Herunterfallen zu hindern, bevor die ungeformten, feuerfesten, freifließenden Erzeugnisse zwischen die Wand oder Decke und die Platten gelangen. Die Stahlteile sind Montagehilfsmittel. Als ungeformte, feuerfeste, freifließende Erzeugnisse kann beispielsweise Beton hinter die Platten gegossen werden. Es sind verschiedene ungeformte, feuerfeste, freifließende Erzeugnisse verwendbar. Je nach Bedarf können ungeformte, feuerfeste, freifließende Erzeugnisse gewählt werden, die keramisch, hydraulisch, chemisch-anorganisch oder chemisch-organisch gebunden sein können. Derartige ungeformte, feuerfeste, freifließende Erzeugnisse werden üblicherweise als "Massen" bezeichnet. Nach dem Hintergießen der ungeformten, feuerfesten, freifließenden Erzeugnisse zwischen die Wand oder Decke und die Platten sind die Platten kraftschlüssig mit der Wand oder Decke verbunden.Each steel part serves only to prevent the plate from falling down before the unshaped, refractory, free-flowing products get between the wall or ceiling and the plates. The steel parts are assembly aids. As unformed, refractory, free-flowing products, for example, concrete can be poured behind the plates. Various unshaped, refractory, free-flowing products can be used. Unformed, refractory, free-flowing products, which may be ceramic, hydraulic, chemical-inorganic or chemical-organic, may be selected as needed. Such unshaped, refractory, free-flowing products are commonly referred to as "bulk". After pouring back the unshaped, refractory, free-flowing products between the wall or ceiling and the plates, the plates are non-positively connected to the wall or ceiling.

Bei der erfindungsgemäßen Feuerfestabkleidung sind die Stahlteile verdeckt hinter den Platten angeordnet. Gleichzeitig wird ein Aushängen der Platten verhindert und die Gestaltung der Platten gewährleistet, dass die Plattenfugen überdeckt sind und so den direkten Durchgang von Schadgasen zu der Wand oder Decke verhindern.In the refractory lining of the invention, the steel parts are hidden behind the plates. At the same time, the plates are prevented from being hung up and the design of the plates ensures that the plate joints are covered, thus preventing the direct passage of harmful gases to the wall or ceiling.

Es hat sich als vorteilhaft erwiesen, in bestimmten Bereichen, z. B. bei Decken, schrägen Wänden, jeweils ein zusätzliches Stahlteil je Platte vorzusehen. Diese zusätzlichen Stahlteile dienen als Montagehilfe für diese Platten.It has proven to be advantageous in certain areas, eg. As in ceilings, sloping walls, each provide an additional steel part per plate. These additional steel parts serve as an assembly aid for these plates.

Gemäß einer besonders bevorzugten Ausführungsform ist auf der Rückseite jeder Platte sowohl im oberen als auch im unteren Bereich eine Nut zum Einführen eines Stahlteiles vorgesehen. Gemäß dieser besonders bevorzugten Ausführungsform ist es möglich, die Verkleidung mit einem weiteren Stahlteil je Platte auszubilden. Zur Vereinfachung bei der Herstellung der Platten sind alle Platten gleich ausgeformt.According to a particularly preferred embodiment, a groove for introducing a steel part is provided on the back of each plate both in the upper and in the lower region. According to this particularly preferred embodiment, it is possible to form the panel with a further steel part per plate. To simplify the manufacture of the plates, all the plates are the same shape.

Gemäß einer weiteren besonders bevorzugten Ausführungsform, ist die auf der Rückseite der Platte angeordnete Nut im Querschnitt T-förmig.According to a further particularly preferred embodiment, the groove arranged on the rear side of the plate is T-shaped in cross-section.

Gemäß einer weiteren besonders bevorzugten Ausführungsform besteht das Stahlteil aus einem Stift, der an der Wand oder Decke befestigt ist und dessen freies Ende ein Gewinde aufweist, in das eine Scheibe geschraubt wird, die in die Nut der Platte eingreift. Hierdurch ist es möglich, die Scheibe soweit in das Gewinde zu schrauben, wie es die gewünschte Lage der Platte erfordert, das heißt der Abstand zwischen der Wand oder Decke und den Platten ist variabel zu gestalten. Dies hat sich bei unebenen Kesselrohrwänden als besonders vorteilhaft herausgestellt.According to a further particularly preferred embodiment, the steel part consists of a pin which is fixed to the wall or ceiling and the free end has a thread into which a disc is screwed, which engages in the groove of the plate. This makes it possible to screw the disc as far as the thread, as required by the desired position of the plate, that is, the distance between the wall or ceiling and the plates is variable. This has proven to be particularly advantageous for uneven boiler tube walls.

Gemäß einer weiteren besonders bevorzugten Ausführungsform ist der Rand jeder Platte umlaufend gestuft ausgebildet. Jeweils der untere Rand der oberen Platte hintergreift den oberen Rand der darunter angeordneten Platte. Der seitliche Rand einer Platte hintergreift den seitlichen Rand der daneben angeordneten Platte. Durch die gestufte Ausbildung der Plattendicke jeder Platte wird somit eine Wand oder Decke gebildet, bei der zwischen den Platten keine ungewünschten Fugen entstehen.According to a further particularly preferred embodiment, the edge of each plate is formed circumferentially stepped. In each case, the lower edge of the upper plate engages behind the upper edge of the underlying plate. The lateral edge of a plate engages behind the lateral edge of the adjacent plate. Due to the stepped design of the plate thickness of each plate thus a wall or ceiling is formed in which no undesirable joints arise between the plates.

Vorzugsweise ist der Rand jeder Platte im Querschnitt gewinkelt ausgebildet.Preferably, the edge of each plate is formed angled in cross-section.

Gemäß einer weiteren besonders bevorzugten Ausführungsform ist der umlaufende Rand zu einem Drittel der Plattendicke abgestuft.According to a further particularly preferred embodiment, the peripheral edge is stepped to one third of the plate thickness.

Die Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert. Es zeigen:

In Fig. 1 und Fig. 2 sind die Platten 1 perspektivisch dargestellt, deren Rand 2 umlaufend gestuft ausgebildet ist. Auf der Rückseite jeder Platte 1 ist im oberen Bereich die Nut 3 ausgebildet. Im unteren Bereich der Rückseite der Platte 1 ist die Nut 4 ausgebildet. Sowohl die Nut 3 als auch die Nut 4 ist im Querschnitt T-förmig.In Fig. 1 and Fig. 2, the plates 1 are shown in perspective, the edge 2 is formed circumferentially stepped. On the back of each plate 1, the groove 3 is formed in the upper region. In the lower region of the back of the plate 1, the groove 4 is formed. Both the groove 3 and the groove 4 is T-shaped in cross section.

Die Draufsicht auf die Rückseite der Platte 1 läßt erkennen, daß oben (oberer Rand 7) und an einer Seite der Platte 1 (seitlicher Rand 9) etwa ein Drittel der Plattendicke über den verbleibenden Rand hinausragt. An der anderen Seite (seitlicher Rand 8) der Platte 1 und am unteren Rand 5 der Platte 1 springt ein Drittel des Randes zurück und der breitere Teil der Plattendicke ragt über den schmäleren Teil hinaus. Der umlaufende Rand 2 der Platte 1 ist etwa zu einem Drittel der Plattendicke abgestuft. Er ist im Querschnitt gewinkelt ausgestaltet. Der breitere Teil der Plattendicke weist zur Wand 16.The plan view of the back of the plate 1 reveals that about one third of the plate thickness projects beyond the remaining edge at the top (upper edge 7) and on one side of the plate 1 (lateral edge 9). On the other side (lateral edge 8) of the plate 1 and at the lower edge 5 of the plate 1 jumps Third of the edge back and the wider part of the plate thickness protrudes beyond the narrower part. The peripheral edge 2 of the plate 1 is stepped about one third of the plate thickness. He is designed angled in cross-section. The wider part of the plate thickness faces the wall 16.

Die Platten 1,6,10 und alle weiteren dargestellten Platten haben dieselbe Ausgestaltung, wie sie in Fig. 1 anhand der Platte 1 dargestellt ist.The plates 1,6,10 and all other plates shown have the same configuration, as shown in Fig. 1 on the basis of the plate 1.

Die Wand 16 besteht aus Rohren 15, die über Rohrflossen 17 verbunden sind. An die Rohrflossen 17 sind die Stahlteile 11 geschweißt. Jedes Stahlteil 11 besteht aus einem Stift 12, der an der Wand 16 befestigt wird und dessen freies Ende ein Gewinde 13 aufweist, in das eine Scheibe 14 geschraubt wird, die in die Nut 3 der Platte 1 eingreifen kann.The wall 16 consists of tubes 15 which are connected by pipe fins 17. At the pipe fins 17, the steel parts 11 are welded. Each steel part 11 consists of a pin 12 which is fixed to the wall 16 and the free end has a thread 13 into which a disc 14 is screwed, which can engage in the groove 3 of the plate 1.

Gemäß Fig. 2 sind bereits mehrere Platten vor der Wand 16 angeordnet, unter anderem die Platte 6, die den oberen Rand 7 aufweist. Die Stahlteile 11 werden zuerst auf die Wand 16 aufgebracht. Dann wird die Platte 1 mit ihrem unteren Rand 5 auf dem oberen Rand 7 der unteren Platte 6 angebracht. Hierbei hintergreift der untere Rand 5 der oberen Platte 1 den oberen Rand 7 der darunter angeordneten Platte 6. Bei jeder Platte hintergreift der seitliche Rand 8 einer Platte 10 den seitlichen Rand 9 der daneben angeordneten Platte 6. Die Vorderseiten der Platten bilden die gewünschte ebene Fläche.According to FIG. 2, a plurality of plates are already arranged in front of the wall 16, inter alia the plate 6, which has the upper edge 7. The steel parts 11 are first applied to the wall 16. Then, the plate 1 is attached with its lower edge 5 on the upper edge 7 of the lower plate 6. In this case, the lower edge 5 of the upper plate 1 engages behind the upper edge 7 of the underlying plate 6. In each plate, the lateral edge 8 of a plate 10 engages behind the lateral edge 9 of the next arranged plate 6. The front sides of the plates form the desired flat surface ,

Beim Anbringen der Platte 1 vor der Wand 16 über der darunter angeordneten Platte 6 dringt das freie Ende des Stahlteiles 11 in die Aussparung 21 auf der Rückseite der Platte 1 ein und die Scheibe 14 ist anschließend beweglich in der Nut 3 angeordnet.When attaching the plate 1 in front of the wall 16 above the underlying plate 6 penetrates the free end of the steel part 11 in the recess 21 on the back of the plate 1 and the disc 14 is then movably disposed in the groove 3.

Hierdurch ist gewährleistet, dass die Platte 1, die mit der darunter angeordneten Platte 6 verbunden ist, nicht von der Wand 16 weggelangen kann. Zwischen den neben- und übereinander angeordneten Platten wie beispielsweise 1,6 oder 10 und der Wand 16 verbleibt ein Spalt 19.This ensures that the plate 1, which is connected to the underlying plate 6, can not get away from the wall 16. Between the side by side and one above the other arranged plates such as 1.6 or 10 and the wall 16 remains a gap 19th

Dieser variable Abstand zwischen den Platten und der zu verkleidenden Wand oder Decke ist beispielsweise wichtig bei vorhandener Restbestiftung sowie bei einer unebenen Wand oder Decke. Die Dehn- bzw. Arbeitsfugen um jede Platte sind variabel in der Ausführung je nach der thermischen bzw. mechanischen Beanspruchung. Die Platten können schnell montiert und demontiert werden, wodurch kurze Stillstandszeiten gewährleistet sind.This variable distance between the panels and the wall or ceiling to be covered is important, for example, in the case of existing residual contamination as well as on an uneven wall or ceiling. The expansion or working joints around each plate are variable in design depending on the thermal or mechanical stress. The plates can be quickly assembled and disassembled, ensuring short downtimes.

Die Stahlteile sind hinter den Platten verdeckt eingebaut. Durch die beschriebene Anordnung wird ein Aushängen der Platten verhindert.The steel parts are concealed behind the plates. By the arrangement described a detachment of the plates is prevented.

Der nunmehr entstandene Spalt 19 zwischen der Wand 16 und den Platten 1,6,10 und den daneben und darüber angeordneten Platten wird mit dem ungeformten, feuerfesten Erzeugnis 18 hintergossen. Hierdurch wird dieser Spalt 19 ausgefüllt. Der maximale Abstand wird horizontal durch die Scheibe 14 bestimmt, die sich auf dem Stift 16 in der Nut 3 befindet.The now resulting gap 19 between the wall 16 and the plates 1,6,10 and the adjacent and above arranged plates is back-molded with the unformed, refractory product 18. As a result, this gap 19 is filled. The maximum distance is determined horizontally by the disc 14 located on the pin 16 in the groove 3.

Als ungeformte, feuerfeste, freifließende Erzeugnisse (Massen) können solche verwendet werden, die keramisch, hydraulisch, chemisch-anorganisch oder chemisch-organisch gebunden sein können. Beispielsweise kann Beton verwendet werden, der gegossen wird. Durch diese ungeformten, feuerfesten, freifließenden Erzeugnisse werden die Platten kraftschlüssig mit der Wand oder Decke verbunden.As unshaped, refractory, free-flowing products (masses), those may be used which may be bonded ceramic, hydraulic, chemical-inorganic or chemical-organic. For example, concrete that is being poured may be used. Through these unformed, refractory, free-flowing products, the plates are non-positively connected to the wall or ceiling.

Es hat sich nunmehr als vorteilhaft erwiesen, in bestimmten Bereichen jeweils ein zusätzliches Stahlteil je Platte vorzusehen. Diese zusätzlichen Stahlteile dienen als Montagehilfe für diese Platten. Um die Rückseite dieser Platten an diesen zusätzlichen Stahlteilen anzuordnen, ist auf der Rückseite jeder Platte im unteren Bereich die Aussparung 20 vorgesehen, in die das Stahlteil eingeführt und nach oben in die Nut 4 gleiten kann.It has now proven to be advantageous to provide an additional steel part per plate in certain areas. These additional steel parts serve as an assembly aid for these plates. To arrange the back of these plates on these additional steel parts is on the back of each plate the recess 20 is provided in the lower region, into which the steel part can be introduced and slide upwards into the groove 4.
