Description

Feuerfeste Wand, insbesondere für einen Verbrennungsofen  Fireproof wall, in particular for a combustion furnace
Die vorliegende Erfindung betrifft eine feuerfeste Wand, insbesondere für einen Verbrennungsofen, mit einer Kesselwand, die durch eine Rohrwand aus durch Stege verbundenen Rohren gebildet ist, und einer im Abstand zur Kesselwand vorgesetzten feuerfesten Schutzverkleidung gemäss dem Oberbegriff von Patentanspruch 1. The present invention relates to a refractory wall, in particular for a combustion furnace, with a boiler wall, which is formed by a pipe wall made of pipes connected by webs, and a refractory protective covering in the distance to the boiler wall according to the preamble of patent claim 1.
Solche feuerfesten Wände werden z.B. in Feuerräumen von Verbrennungsanlagen eingesetzt. Die Kesselwand ist dabei oft als metallene Rohrwand ausgebildet und besteht in der Regel aus durch Stege verbundenen Rohren. Die im Abstand zur Rohrwand vorgehängte feuerfeste Schutzverkleidung soll die Rohrwand vor Korrosion durch Rauchgase schützen. Die feuerfeste Schutzverkleidung ist in der Regel aus in Reihen und Spalten neben bzw. übereinander angeordneten Platten gebildet. Feuerfeste Wände werden z.B. auch bei Wirbelschichtöfen eingesetzt, bei denen die Kesselwand aus einer mehr oder weniger dicken einfachen Metallwand besteht. Auch hier soll die Kesselwand bzw. Metallwand vor Korrosion geschützt werden. Such refractory walls are e.g. used in combustion chambers of combustion plants. The boiler wall is often designed as a metal pipe wall and is usually made of webs connected by pipes. The fire-resistant protective cover, which is suspended at a distance from the pipe wall, is intended to protect the pipe wall from corrosion by flue gases. The refractory protective cover is usually formed in rows and columns next to or above one another arranged plates. Refractory walls are e.g. also used in fluidized bed ovens, where the boiler wall consists of a more or less thick simple metal wall. Again, the boiler wall or metal wall to be protected from corrosion.
Die Kesselwände und Schutzverkleidungen werden in den heutigen The boiler walls and protective coverings are in today's
Verbrennungsanlagen oftmals Temperaturen von über 1000°C ausgesetzt und erfahren auch bei geeigneter Materialwahl aufgrund der grossen Incineration plants often exposed to temperatures of over 1000 ° C and experienced even with a suitable choice of material due to the large
Temperaturunterschiede der einzelnen Betriebszustände Dehnungen und Temperature differences of the individual operating conditions strains and
Kontraktionen. Die Temperaturunterschiede sind bei den Schutzverkleidungen im Allgemeinen grösser als bei den Kesselwänden selbst, was bei der Materialwahl und/oder Ausgestaltung der Schutzverkleidungen berücksichtigt werden muss. damit die Schutzverkleidungen nicht durch grössere Dehnungen und Kontraktionen als die Kesselwände zerstört werden. Die Schutzverkleidungen bzw. die Platten derselben werden daher in der Regel nicht starr an den Kesselwänden befestigt, sondern mit Spiel, so dass in beschränktem Umfang Ausgleichsbewegungen parallel zu den Kesselwänden möglich sind. Die Wahl eines geeigneten Materials für die Schutzverkleidung ermöglicht es, dass die Schutzverkleidung für jeden Betriebszustand auf die Kessel wand abgestimmt ist. Für Kesselwände aus Stahl haben sich Schutzverkleidungen aus keramischen Werkstoffen, insbesondere SiC. bewährt, 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. Contractions. The temperature differences are generally greater for the protective linings than for the boiler walls themselves, which must be taken into account in the choice of material and / or design of the protective linings. so that the protective coverings are not destroyed by greater strains and contractions than the boiler walls. The protective panels or the plates thereof are therefore usually not rigidly attached to the boiler walls, but with play, so that compensating movements are possible parallel to the boiler walls to a limited extent. The choice of a suitable material for the protective covering makes it possible for the protective lining to be matched to the boiler wall for every operating condition. For steel boiler walls, protective linings made of ceramic materials, in particular SiC. proven, wherein the SiC content can be very different. In practice, SiC masses or SiC plates with a SiC content of 30% -90% are used.
Die Platten der Schutzverkleidung sind in der Regel durch verschiedene Massnahmen bis zu einem gewissen Grad gegenseitig abgedichtet, um den Durchtritt von The panels of the protective covering are usually sealed to each other to a certain extent by various measures to prevent the passage of
Rauchgasen zu verhindern. Die Massnahmen können z.B. in die Trennfugen eingelegte feuerfeste Filzstreifen und/oder eine abgestufte und gegenseitig ineinandergreifende Ausbildung der Plattenränder und/oder zusätzliche Verkittungen umfassen. Die gegenseitige Abdichtung der Platten in deren Trennlugen ist konstruktiv relativ aufwändig und erfordert auch einen beträchtlichen Prevent flue gases. The measures may e.g. Include in the parting lines refractory felt strips and / or a stepped and mutually interlocking formation of the plate edges and / or additional bonding. The mutual sealing of the plates in their Trennlugen is structurally relatively complex and also requires a considerable
Wartungsaufwand. Es besteht daher ein Bedürfnis, bei solchen aus einzelnen Platten zusammengesetzten Schutzverkleidungen mit möglichst wenigen und vor allem möglichst schmalen und entsprechend wartungsfreien Trennfugen auszukommen. Maintenance. There is therefore a need to get along with as few and especially narrow as possible and correspondingly maintenance-free joints in such composed of individual panels protective panels.
Angesichts der Nachteile der bekannten feuerfesten Wandsysteme liegt der Erfindung die Aufgabe zugrunde, eine feuerfeste Wand der gattungsgemässen Art dahingehend zu verbessern, dass zumindest ein Teil der Trenn l ugen zwischen den Platten der Schutzverkleidung wegfällt oder vernachlässigbar schmal ist. In view of the disadvantages of the known fireproof wall systems, the invention has the object to improve a refractory wall of the generic type such that at least part of the separating gaps between the plates of the protective cover is omitted or is negligibly narrow.
Diese Aufgabe wird durch die erfmdungsgemässe feuerfeste Wand gelöst, wie sie im unabhängigen Patentanspruch 1 definiert ist. Besonders vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich aus den abhängigen This object is achieved by the erfmdungsgemäße refractory wall, as defined in independent claim 1. Particularly advantageous developments and refinements of the invention will become apparent from the dependent
Patentansprüchen. Claims.
Das Wesen der Erfindung besteht im Folgenden: Eine feuerfeste Wand, insbesondere für einen Verbrennungsofen, umfasst eine Kesselwand, die durch eine Rohrwand aus durch Stege verbundenen Rohren gebildet ist, und eine im Abstand zu dieser vorgesetzte feuerfeste Schutzverkleidung aus einer Vielzahl von in Reihen und Spalten neben- bzw. übereinander angeordneten feuerfesten Platten, die über je mindestens eine Plattenhalterung an der Kesselwand befestigt sind, wobei sich pro Platte jeweils ein an der Platte angeordnetes Brückenelement in vertikaler Richtung auf einer Plattenhalterung abstützt. Die Brückenelemente teilen die Höhe der Platten jeweils in einen kürzeren Plattenabschnitt und einen längeren Plattenabschnitt. The essence of the invention consists in the following: A refractory wall, in particular for a combustion furnace, comprises a boiler wall formed by a tube wall made of webs connected by webs and a refractory protective covering of a plurality of rows and columns spaced from it beside or above each other arranged refractory plates, the above each at least one plate holder are fixed to the vessel wall, wherein each plate is supported on the plate arranged bridge element in the vertical direction on a plate mount per plate. The bridge members each divide the height of the panels into a shorter panel section and a longer panel section.
Zumindest einige der Platten sind in vertikaler Richtung paarweise angeordnet, wobei die beiden Platten jedes Plattenpaars jeweils mit ihren kürzeren Plattenabschnitten aufeinanderstossend angeordnet sind. At least some of the plates are arranged in pairs in the vertical direction, with the two plates of each plate pair being arranged abutting each other with their shorter plate sections.
Durch die spezielle Anordnung der Brückenelemente innerhalb der Platten und die abwechselnde Anordnung der Platten bezüglich ihrer längeren und kürzeren Due to the special arrangement of the bridge elements within the plates and the alternate arrangement of the plates with respect to their longer and shorter
Plattenabschnitte kann die Anzahl der horizontalen Trennfugen stark reduziert werden. Plate sections, the number of horizontal joints can be greatly reduced.
Vorteilhafterweise stützen sich die untere Platte jedes Plattenpaars jeweils hängend und die obere Platte jedes Plattenpaars jeweils stehend an den Plattenhalterungen ab. Advantageously, the lower plate of each pair of plates are each suspended and the upper plate of each pair of plates are each supported vertically on the plate holders.
Durch die abwechselnd stehende und hängende Abstützung der Platten wird erreicht, dass die beiden Platten jeweils eines Plattenpaars praktisch fugenfrei By alternately standing and hanging support of the plates is achieved that the two plates in each case a pair of plates virtually joint-free
aneinanderstossend angeordnet werden können. can be arranged abutting each other.
Gemäss einer besonders vorteilhaften Ausführungsform sind die beiden Platten jedes Plattenpaars gleich ausgebildet und gegenseitig um 180° gedreht angeordnet. Dies ermöglicht es, für die gesamte Schutzverkleidung denselben Plattentyp zu verwenden. According to a particularly advantageous embodiment, the two plates of each pair of plates are identical and arranged mutually rotated by 180 °. This makes it possible to use the same plate type for the entire protective covering.
Zweckmässigerweise ist jeweils der unteren Platte eines Plattenpaars die obere Platte eines darunterliegenden benachbarten Plattenpaars benachbart, wobei sich zwischen dieser unteren Platte und dieser oberen Platte eine Trennfuge befindet. Die Trennfuge erlaubt thermische Ausgleichsbewegungen der Platten. Conveniently, each of the lower plate of a plate pair is adjacent the upper plate of an underlying adjacent plate pair, with a parting line between said lower plate and said upper plate. The parting line allows thermal compensation movements of the plates.
Gemäss einer alternativen Ausfuhrungsform ist jeweils zwischen zwei vertikal benachbarten Plattenpaaren eine Zwischenplatte angeordnet, wobei sich zwischen der unteren Platte eines Plattenpaars und der Zwischenplatte sowie zwischen der oberen Platte eines darunterliegenden benachbarten Plattenpaars und der Zwischenplatte jeweils eine Trennfuge befindet. According to an alternative embodiment, an intermediate plate is arranged in each case between two vertically adjacent plate pairs, wherein between the lower plate of a plate pair and the intermediate plate and between the upper Plate of an underlying adjacent plate pair and the intermediate plate each has a parting line.
Die Fugenbreite der Trennfugen beträgt zweckmässigerweise 3-12 mm, vorzugsweise 5-10 mm. Dies ermöglicht thermische Ausgleichsbewegungen der Platten bei optimiertem Abdichtungsaufwand. The joint width of the joints is conveniently 3-12 mm, preferably 5-10 mm. This allows thermal compensation movements of the plates with optimized sealing effort.
Zweckmässigerweise beträgt die Fugenbreite von all fäll igen Stossfugen zwischen den aufeinanderstossenden kürzeren Plattenabschnitten der beiden Platten jedes Conveniently, the joint width of all mature butt joints between the abutting shorter plate sections of the two plates is each
Plattenpaars jeweils höchstens 5 mm, vorzugsweise höchstens 3 mm. Derart kleine Stossfugen sind bezüglich Wartungsaufwand vernachlässigbar. Plate pairs each at most 5 mm, preferably at most 3 mm. Such small butt joints are negligible in terms of maintenance.
Zweckmässigerweise ist ein zwischen der Kesselwand und der Schutzverkleidung befindlicher Zwischenraum mit einem feuerfesten Material ausgegossen. Dies erhöht einerseits die Dichtigkeit gegen eindringende Rauchgase und verbessert anderseits den Wärmeübergang zur Kesselwand. Conveniently, a space located between the boiler wall and the protective lining is filled with a refractory material. On the one hand, this increases the impermeability to penetrating flue gases and, on the other hand, improves the heat transfer to the boiler wall.
Weiters ist es zweckmässig, wenn die Platten vertikal durchgehende, nach innen erweiterte Nuten aufweisen, in welche die Plattenhalterungen eingreifen, und wenn vorzugsweise die Nuten ebenfalls mit einem feuerfesten Material ausgegossen sind. Dies erhöht die Stabilität der Schutzverkleidung und den Wärmeübergang. Furthermore, it is expedient if the plates have vertically continuous, inwardly widened grooves in which engage the plate mounts, and preferably when the grooves are also filled with a refractory material. This increases the stability of the protective cover and the heat transfer.
Zweckmässigerweise sind die Platten gegen Verkippung aus der Schutzverkleidung heraus gesichert. Dies kann beispielsweise mittels zusätzlicher Conveniently, the plates are secured against tilting out of the protective cover. This can be done for example by means of additional
Plattenrückhalterungen geschehen und ist insbesondere während der Montage der feuerfesten Wand bzw. des Ausgiessens der Zwischenräume von Vorteil. Plattenrückhalterungen happen and is particularly during assembly of the refractory wall or the pouring of the interstices of advantage.
Vorteilhafterweise sind die Trenn fugen gegen Eindringen von Rauchgasen abgedichtet. Advantageously, the joints are sealed against the ingress of flue gases.
Zweckmässigerweise sind die Plattenhalterungen an den Stegen der Rohrwand befestigt. Dadurch wird der Druckkörper nicht beeinträchtigt und Kontrollen von einem anerkannten Fachmann oder einer Behörde sind daher überflüssig. Ein weiterer Vorteil besteht darin, dass die Plattenhai terungen. durch ihre Verbindung mit den Stegen gekühlt sind. Conveniently, the plate mounts are attached to the webs of the pipe wall. As a result, the pressure hull is not affected and checks by a recognized expert or authority are therefore superfluous. Another Advantage is that the Plattenhai extensions. cooled by their connection with the webs.

Die in den Figuren 1-3 beispielsweise dargestellte erfmdungsgemässe feuerfeste Wand umfasst eine hier als Rohrwand 1 ausgebildete Kesselwand und eine im Abstand dazu vorgesetzte Schutzverkleidung 2, wobei zwischen der Kessel- bzw. Rohrwand 1 und der Schutzverkleidung 2 ein Zwischenraum 3 gebildet ist. Die Kessel- bzw. Rohrwand 1 besteht aus einer Vielzahl von im praktischen Einsatz vertikalen Rohren 11 , welche durch Stege 12 in gegenseitigem Abstand The erfmdungsgemäße refractory wall shown in Figures 1-3, for example, comprises a here designed as a pipe wall 1 boiler wall and at a distance superior protective cover 2, wherein between the boiler or Pipe wall 1 and the protective cover 2, a gap 3 is formed. The boiler or pipe wall 1 consists of a plurality of vertical use in practice pipes 11, which by webs 12 at a mutual distance
zusammengehalten sind. Die Rohre 11 und die Stege 12 bestehen üblicherweise aus Stahl. Die Schutzverkleidung 2 umfasst eine Vielzahl von neben- und übereinander angeordnete feuerfeste Platten 21. Die Platten sind beispielsweise keramische SiC- Platten, vorzugsweise SiC 90-Platten mit einem SiC-Gehalt von ungefähr 90% in der Herstellung, die bis über 1000°C feuerbeständig sind. Jede Platte 21 ist mittels Plattenhalterungen 22 an der Rohrwand 1 befestigt. Die Plattenlialterungen bestehen aus hitzebeständigem Stahl. z.B. Stahl Nr. 310 nach AIS I -Norm oder Werkstoff Nr. 1.4845 nach DIN 17440. Die Plattenhalterungen 22 umfassen im Wesentlichen je einen an einem Steg 12 angeschweissten Gewindebolzen 22a und eine auf dem Gewindebolzen sitzende Mutter 22b. Die Plattenhalterungen 22 greifen in vertikal durchgehende, nach innen erweiterte Nuten 21a der Platten 21 ein und legen den Abstand der Platten 21 zur Rohrwand 1 fest. Die Plattenhalterungen 22 dienen ebenfalls zur Stützung (Aufhängung) der Platten 21 in vertikaler Richtung, wobei die Platten 21 mit an ihnen angeordneten (angeformten) Brückenelementen 21b auf den Plattenhalterungen 22 aufliegen. Die Platten 21 sind dabei in vertikaler Richtung in gewissem Masse beweglich, um so thermisch bedingte Ausdehnungs- bzw. are held together. The tubes 11 and the webs 12 are usually made of steel. The protective cover 2 comprises a multiplicity of juxtaposed and superimposed refractory plates 21. The plates are, for example, SiC ceramic plates, preferably SiC 90 plates having an SiC content of about 90% in the manufacture, which are fire resistant up to more than 1000 ° C are. Each plate 21 is fastened to the tube wall 1 by means of plate holders 22. The plate spacings are made of heat-resistant steel. e.g. Steel no. 310 according to AIS I standard or material no. 1.4845 according to DIN 17440. The plate mounts 22 substantially each comprise a threaded bolt 22a welded to a web 12 and a nut 22b seated on the threaded bolt. The plate holders 22 engage in vertically continuous, inwardly widened grooves 21 a of the plates 21 and set the distance of the plates 21 to the tube wall 1 fixed. The plate supports 22 also serve to support (suspend) the plates 21 in the vertical direction, with the plates 21 resting on the plate holders 22 with bridge elements 21b arranged on them (molded). The plates 21 are movable in the vertical direction to some extent, so thermally induced expansion or
Kontraktionsbewegungen zuzulassen. Zwischen den nebeneinander angeordnetenAllow contraction movements. Between the juxtaposed
Platten 21 verlaufen vertikale Trennfugen 23 (Fig. 2) und zwischen den übereinander angeordneten Platten 21 befinden sich horizontale Stossfugen 24a und Trenn fugen 24b (Figuren 1 und 3). Der Zwischenraum 3 zwischen der Kessel- bzw. Rolirwand 1 und der Schutzverkleidung 2 sowie die vertikalen Nuten 21a der Platten 21 sind mit einem feuerfesten Material (nicht dargestellt) ausgegossen. Plates 21 extend vertical parting lines 23 (Figure 2) and between the superimposed plates 21 are horizontal butt joints 24a and parting lines 24b (Figures 1 and 3). The space 3 between the boiler or Rolirwand 1 and the protective cover 2 and the vertical grooves 21 a of the plates 21 are filled with a refractory material (not shown).
Der wesentliche Unterschied der erfindungsgemässen feuerfesten Wand gegenüber herkömmlichen feuerfesten Wänden dieser Art bestellt darin, dass, in vertikaler Richtung gesehen, benachbarte Platten 21 abwechselnd einmal praktisch bzw. The essential difference of the inventive refractory wall over conventional refractory walls of this type ordered in that, seen in the vertical direction, adjacent plates 21 alternately once practically or
zumindest fast abstandslos benachbart sind (Stossfugen 24a) und das andere Mal einen ausgeprägteren vertikalen gegenseitigen Abstand aufweisen (Trennfugen 24b). Zwei jeweils unmittelbar aneinanderstossende Platten 21 bilden dabei jeweils ein Plattenpaar 21 P (Figuren 4 und 5). Erreicht wird diese Plattenkonfiguration durch entsprechend vertikal beabstandete Anordnung der Plattenhalterungen 22 und durch entsprechende Anordnung der Brückenelemente 21b in den Platten 21 , die sich bei den Platten 21 einer ersten Reihe jeweils im unteren Bereich der Platten 21 und bei den Platten 21 der darunterliegenden zweiten Reihe jeweils im oberen Bereich der Platten 21 befinden. Die Platten 21 mit den Brückenelementen 21 b im unteren Bereich stehen also gewissermassen auf den Plattenhalterungen 22, während die Platten mit den Brückenelementen 21b im oberen Bereich gewissermassen an den Plattenhalterungen 22 hängen. Nicht dargestellte Rückhalteelemente können optional dafür sorgen, dass die Platten 21 nicht aus der Schutzverkleidung heraus kippen können. Die Abstände zwischen den Brückenelementen 21 b im unteren at least almost without spacing adjacent (butt joints 24a) and the other time have a more pronounced vertical mutual distance (parting lines 24b). Two directly juxtaposed plates 21 each form a pair of plates 21 P (FIGS. 4 and 5). This disk configuration is achieved by correspondingly vertically spaced arrangement of the plate mounts 22 and by appropriate arrangement of the bridge elements 21b in the plates 21, which in the plates 21 a first row respectively in the lower region of the plates 21 and the plates 21 of the underlying second row respectively in the upper region of the plates 21 are located. The plates 21 with the bridge elements 21 b in the lower area are thus to some extent on the plate mounts 22, while the plates hang with the bridge elements 21 b in the upper region to some extent on the plate mounts 22. Not shown retaining elements can optionally ensure that the plates 21 can not tilt out of the protective cover. The distances between the bridge elements 21 b in the lower
Plattenbereich und dem unteren Rand der Platten 21 sind deutlich geringer als die Abstände zwischen denselben Brückenelementen 21 b und dem oberen Rand der Platten 21 . Umgekehrt sind die Abstände zwischen den Brückenelementen 21 b im oberen Plattenbereich und dem oberen Rand der Platten 21 deutlich geringer als die Abstände zwischen denselben Brückenelementen 21 b und dem unteren Rand der Platten 21 . Die Brückenelemente 21b teilen also die Höhe der Platten jeweils unsymmetrisch in einen kürzeren und einen längeren vertikalen Plattenabschnitt 21c bzw. 21d (Fig. 3). Dort, wo Platten 21 mit ihren jeweils kürzeren Plattenabschnitten 21c benachbart sind, besitzen die Stossfugen 24a nur eine geringfügige bzw. fast verschwindende (vertikale) Fugenbreite, während die Trennfugen 24b zwischen benachbarten längeren Plattenabschnitten 21d deutlich ausgeprägter sind und eine entsprechend grössere Fugenbreite besitzen. Die praktisch vernachlässigbare Fugenbreite der Stossfugen 24a ist möglich, weil die thermisch bedingte  Plate area and the lower edge of the plates 21 are significantly smaller than the distances between the same bridge elements 21 b and the upper edge of the plates 21st Conversely, the distances between the bridge elements 21 b in the upper plate region and the upper edge of the plates 21 are significantly smaller than the distances between the same bridge elements 21 b and the lower edge of the plates 21st The bridge elements 21b thus divide the height of the plates in each case asymmetrically into a shorter and a longer vertical plate section 21c or 21d (FIG. 3). Where plates 21 are adjacent with their respective shorter plate portions 21c, the butt joints 24a have only a slight (almost) vanishing (vertical) joint width, while the parting lines 24b between adjacent longer plate portions 21d are much more pronounced and have a correspondingly larger joint width. The practically negligible joint width of the butt joints 24a is possible because the thermally induced
Längenänderung der (vertikal) kürzeren Plattenabschnitte 21c nur relativ gering ist, während die thermisch bedingte Längenänderung der (vertikal) längeren Length change of (vertical) shorter plate portions 21c is only relatively small, while the thermally induced change in length of the (vertical) longer
Plattenabschnitte 21d stärker ist. Plate portions 21d is stronger.
Die Fugenbreite der Stossfugen 24a beträgt typischerweise 0-5 mm. vorzugsweise 0-3 mm, diejenige der Trennfugen 24b beträgt typischerweise 3-12 mm. The joint width of the butt joints 24a is typically 0-5 mm. preferably 0-3 mm, that of the parting lines 24b is typically 3-12 mm.
vorzugswei se 5-10 mm . vorzugswei se 5-10 mm.
Aus den Figuren 1 und 3 ist ersichtlich, dass die längs den Stossfugen 24a benachbarten Platten 21 eines Plattenpaars 21P jeweils (bezüglich der Stossfugen 24a) spiegelbildlich ausgebildet sind. De facto sind alle Platten 21 gleich ausgebildet, aber in vertikaler Richtung ist jede zweite Platte 21 eines Plattenpaars 21 P gegenüber der jeweils ersten Platte 21 des Plattenpaars 21P um 180° in der Plattenebene bzw. um eine Normale auf die Platte gedreht angeordnet. Dies hat den grossen Vorteil, dass für die gesamte Schutzverkleidung 2 derselbe Typ von Platten 21 eingesetzt werden kann. From FIGS. 1 and 3, it can be seen that the plates 21 of a pair of plates 21P adjacent to each other along the butt joints 24a are respectively (with respect to the butt joints 24a) are mirror images. In fact, all the plates 21 are formed the same, but in the vertical direction, each second plate 21 of a plate pair 21 P is disposed 180 ° in the plane of the plate from the first plate 21 of the plate pair 21P, respectively, and rotated normal to the plate. This has the great advantage that the same type of panels 21 can be used for the entire protective covering 2.
In Fig. 5 ist rein schematisch eine alternative Konfiguration der Platten der In Fig. 5 is purely schematically an alternative configuration of the plates of
Schutzverkleidung dargestellt. Hierbei ist in vertikaler Richtung jeweils zwischen zwei Plattenpaaren 21P eine Zwischenplatte oder Dilatationsplatte 21Z angeordnet, die zu den beiden angrenzenden Plattenpaaren 21P jeweils durch eine Trennfuge 24b getrennt ist. Die Zwischenplatte 21Z ist gleich ausgebildet wie alle anderen Platten 21 der Schutzverkleidung und auch auf die gleiche Weise an der (in dieser Figur nicht dargestellten) Kessel- bzw. Rohrwand 1 befestigt. Protective cover shown. In this case, an intermediate plate or dilatation plate 21Z is arranged in each case between two plate pairs 21P in the vertical direction, which intermediate plate is separated from the two adjacent plate pairs 21P by a parting line 24b. The intermediate plate 21Z is formed the same as all the other plates 21 of the protective cover and also in the same manner to the (not shown in this figure) boiler or tube wall 1 attached.
Insbesondere die Trennfugen 24b können durch eingelegte feuerfeste Filzstreifen und/oder eine abgestufte und gegenseitig ineinandergreifende Ausbildung der Plattenränder und/oder zusätzliche Verkittungen abgedichtet, d.h. gegen Eindringen von Rauchgasen geschützt sein. In particular, the parting lines 24b may be sealed by inserted refractory felt strips and / or a stepped and mutually interlocking formation of the plate edges and / or additional cements, i. be protected against the ingress of flue gases.
