Abstract

The plates (3,4) have a dovetail guide (7) on two of their opposing sides. Every two plates (3) in a row are attached to the tube wall by a bolt (5) so that the plates (4) between those which are attached, are held against the wall. Fire proof putty is filled into the gap between the plates and there are recesses (8) in the edges of the plates forming plugs of putty and protecting against the putty being broken. The plates in one row are offset to those in the opposite following row. USE/ADVANTAGE - For protection of waste burning systems against corrosion and erosion by the combustion gases. The assembly expenditure is reduced.

Description

Die Erfindung betrifft eine aus keramischen Platten bestehende Verkleidung einer Rohrwand gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an existing of ceramic plates Cladding a pipe wall according to the preamble of Claim 1.

Derartige Verkleidungen dienen dazu, die metallische Rohrwand des Feuerraumes z. B. von Müllverbrennungsanlagen vor Korrosion und Erosion durch das Verbrennungsgas zu schützen. Bei bekannten Verkleidungen wird jede Platte durch mehrere Bolzen an der Rohrwand befestigt (FR-PS 24 95 284). Es ist weiterhin bekannt (DE-PS 40 07 662), die Befestigungselemente zwischen zwei Platten anzuordnen, so daß die Befestigungselemente jeweils zwei benachbarte Platten halten. Auch bei dieser Anordnung ist jede einzelne Platte über Befestigungselemente an der Rohrwand befestigt. Die Montage einer solchen Rohrwandverkleidung gestaltet sich zeitaufwendig.Such claddings serve the metallic pipe wall of the Firebox z. B. from waste incineration plants from corrosion and Protect erosion from the combustion gas. At acquaintances Each panel is fastened by several bolts to the panel Pipe wall attached (FR-PS 24 95 284). It is still known (DE-PS 40 07 662), the fasteners between two plates to arrange so that the fasteners two each hold adjacent panels. With this arrangement, too, everyone is single plate via fasteners on the pipe wall attached. The assembly of such a pipe wall cladding is time-consuming.

Der Erfindung liegt die Aufgabe zugrunde, die aus Platten bestehende Verkleidung so zu gestalten, daß der Aufwand für die Montage der Platten verringert wird.The invention has for its object that of plates to design existing cladding so that the effort for Assembly of the plates is reduced.

Diese Aufgabe wird bei einer gattungsgemäßen Verkleidung erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This task is performed with a generic cladding according to the invention by the characterizing features of Claim 1 solved. Advantageous embodiments of the Invention are specified in the subclaims.

Bei der erfindungsgemäßen Verkleidung braucht nur jede zweite Platte an der Rohrwand befestigt zu werden. Die dazwischenliegende Platte wird aufgrund der Schwalbenschwanzführung der Kanten mittelbar durch zwei benachbarte unmittelbar an der Rohrwand befestigte Platten gehalten.In the paneling according to the invention only every second needs Plate to be attached to the pipe wall. The intermediate plate is due to the Dovetail guidance of the edges indirectly by two Adjacent plates directly attached to the pipe wall held.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher erläutert. Es zeigenAn embodiment of the invention is in the drawing shown and is explained in more detail below. Show it

Fig. 1 die Seitenansicht einer Verkleidung und Fig. 1 is a side view of a panel and

Fig. 2 den Schnitt II-II nach Fig. 1 in einem vergrößerten Maßstab. Fig. 2 shows the section II-II of FIG. 1 on an enlarged scale.

Eine Rohrwand besteht aus von Wasser oder einem Wasser-Dampf- Gemisch durchströmten Rohren 1, die durch zwischengelegte Stege 2 gasdicht miteinander verschweißt sind. Die Rohrwand kann die Wand eines Feuerraumes eines Müllverbrennungskessels darstellen. Auf der dem Feuerraum zugewandten Seite ist die Rohrwand mit keramischen Platten 3, 4 verkleidet.A pipe wall consists of pipes 1 through which water or a water-steam mixture flows and which are welded to one another in a gas-tight manner by interposed webs 2 . The pipe wall can represent the wall of a combustion chamber of a waste incineration boiler. On the side facing the combustion chamber, the tube wall is clad with ceramic plates 3 , 4 .

Die Platten 3, 4 sind der Kontur der Rohrwand angepaßt und werden in einem geringen Abstand von der Rohrwand gehalten. Der verbleibende Raum zwischen den Platten 3,4 und der Rohrwand ist mit einem feuerfesten Kitt ausgefüllt.The plates 3 , 4 are adapted to the contour of the tube wall and are kept at a short distance from the tube wall. The remaining space between the plates 3, 4 and the pipe wall is filled with a refractory putty.

Die Befestigung der Platten 3, 4 an der Rohrwand erfolgt über Bolzen 5, die jeweils auf einen Steg 2 zwischen den Rohren 1 aufgeschweißt sind. Jede zweite Platte 3 ist mit einer Durchgangsbohrung versehen, durch die ein Bolzen 5 greift. Die Platte 3 ist durch eine auf den Bolzen 5 aufgeschraubte Mutter 6 oder durch eine aufgesteckte Befestigungsschraube fixiert. Der Kopf des Bolzens 5 ist durch einen Stopfen aus feuerfestem Kitt oder durch eine Kappe abgedeckt.The plates 3 , 4 are fastened to the tube wall by means of bolts 5 , which are each welded onto a web 2 between the tubes 1 . Every second plate 3 is provided with a through hole through which a bolt 5 engages. The plate 3 is fixed by a nut 6 screwed onto the bolt 5 or by an attached fastening screw. The head of the bolt 5 is covered by a plug made of refractory cement or by a cap.

Alle Platten 3, 4 sind an zwei gegenüberliegenden Seiten mit einer aufeinander angepaßten Schwalbenschwanzführung 7 versehen. Die Schwalbenschwanzführung 7 der von einem Bolzen 5 durchdrungenen Platte 3 verjüngt sich in Richtung auf die Rohrwand. Auf diese Weise halten jeweils zwei an der Rohrwand über Bolzen befestigte Platten 3 eine zwischen ihnen eingeschlossene Platte 4 und bilden so einen geschlossenen Steinverband. Die Platte 4 ist dabei nicht unmittelbar an der Rohrwand befestigt.All plates 3 , 4 are provided on two opposite sides with a dovetail guide 7 which is adapted to one another. The dovetail guide 7 of the plate 3 penetrated by a bolt 5 tapers in the direction of the tube wall. In this way, two plates 3 fastened to the pipe wall by bolts each hold a plate 4 enclosed between them and thus form a closed stone structure. The plate 4 is not attached directly to the pipe wall.

Wie aus Fig. 1 hervorgeht, sind die Platten 3, 4 reihenweise übereinander angeordnet. Dabei sind die Fugen zwischen den Platten 3, 4 innerhalb einer Reihe gegenüber der nachfolgenden Reihe versetzt angeordnet. Sofern die Feuerführung in dem mit den Platten 3, 4 ausgekleideten Feuerraum so eingestellt ist, daß flüssige Schlacke entsteht, wird dieser Schlackenfluß durch die versetzte Fugenanordnung daran gehindert, die Plattenfugen auszuwaschen.As can be seen from Fig. 1, the plates 3 , 4 are arranged in rows one above the other. The joints between the plates 3 , 4 are arranged offset within a row with respect to the following row. If the fire control in the firebox lined with the plates 3 , 4 is set so that liquid slag is formed, this flow of slag is prevented by the offset joint arrangement from washing out the plate joints.

Der Spalt zwischen zwei benachbarten Platten 3, 4 ist mit einem feuerfesten Kitt ausgefüllt. Um ein Ausbrechen des Kittes aus den Fugen zu verhindern, sind im Bereich der Schwalbenschwanzführung 7 in den Kanten der Platten 3, 4 Ausnehmungen 8 vorgesehen. In diese Ausnehmungen dringt der Kitt ein und bildet einen Stopfen.The gap between two adjacent plates 3 , 4 is filled with a refractory putty. To prevent the putty from breaking out of the joints, recesses 8 are provided in the region of the dovetail guide 7 in the edges of the plates 3 , 4 . The putty penetrates into these recesses and forms a stopper.
