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 several side by side and one above the other Sheets and with steel parts attached to the wall or ceiling to be clad are, the back of each plate at least in the upper area a groove has, in which a steel part engages.

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, especially industrial furnaces, require a refractory Wall construction to separate the boiler room from the pipe units. To this end, the tubular steel units are protected by means of curtain plates. Here, the tubular steel units to be protected are covered over a large area with the Pipe wall panels clad and the gaps shed.

Es sind mehrere Feuerfestabkleidungen bekannt, bei denen die Rohrwandplatten mittels Stahlteilen gehalten werden, wobei derartige Stahlteile zusätzlich eine Tragfunktion für die Platten ausüben.Several refractory linings are known in which the Pipe wall panels are held by means of steel parts, such steel parts additionally perform a supporting 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.Refractory linings are also known, in which in addition to the steel parts additional support elements are provided, the disadvantage of which is that the preparation of the pipe wall for attaching the plates is time-consuming because 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 DE-PS 40 07 662 is an anchoring device for Tubular steel slabs covering stone slabs are known, to which the pipes connecting tube fins are arranged and on which the tube wall plates can be attached. A disadvantage of this known Anchoring device is that this anchoring device in the Joints are arranged between the tube wall panels.

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 WO 97/09577 A1 a refractory lining according to the in The preamble of claim 1 features known. At this Known refractory lining, the plates by means of screws on the Pipe wall attached. Each plate is screwed on from the outside, one There is a hole at the top of the plate through which the screw can be screwed tight. The disadvantage of such a hole, even if it is very small is that gases can penetrate, which too damage the protective pipe wall or cause corrosion at certain points this pipe wall can lead. Another disadvantage of such Fastening arrangement is that the steel part and in particular the Screws that 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.

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 one below 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 movable in the Groove 3 arranged.

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 arranged with the one below Plate 6 is connected, can not get away from the wall 16. Between the plates arranged next to and on top of each other, such as 1.6 or 10 and the wall 16 remains a gap 19.

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 to be clad or blanket is important, for example, with existing residual pinning as well as with an uneven wall or ceiling. The expansion or construction joints around each panel are variable in design depending on the thermal or mechanical Stress. The panels can be quickly assembled and disassembled, which ensures 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. Through the described arrangement prevents the plates from being detached.

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 gap 19 now formed between the wall 16 and the plates 1,6,10 and the plates arranged next to and above it with the unshaped, refractory product 18 poured. This will make this Gap 19 filled. The maximum distance is horizontal through the disk 14 determined, which is 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.Such as unshaped, refractory, free-flowing products (masses) can be used which are ceramic, hydraulic, chemical-inorganic or can be chemically-organically bound. For example, concrete can be used, which is poured. Through these unshaped, fireproof, free-flowing products are non-positively attached to the wall or Ceiling connected.

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 in certain areas to provide an additional steel part per plate. These additional steel parts serve as an assembly aid for these panels. To the back of these plates To arrange these additional steel parts is on the back of each plate the recess 20 is provided in the lower area, into which the steel part inserted and can slide up into the groove 4.
