Description

Die Erfindung betrifft eine Platte für ein Schutzsystem für eine Kesselrohrwand mit einer Rückseite, einer Vorderseite und die Rück- und Vorderseite verbindende Seiten sowie ein Schutzsystem für eine Kesselrohrwand mit einem an der Kesselrohrwand befestigten Halteelement mit Durchgangsbohrung, einer Platte und einem durch die Durchgangsbohrung durchgreifenden Verankerungselement. Derartige Platten und Schutzsysteme werden in Verbrennungsanlagen zum Schutz von Kesselrohrwänden vor Rauchgas eingesetzt.The invention relates to a plate for a protection system for a boiler tube wall having a back, a front and the rear and front connecting sides and a protection system for a boiler tube wall with a fixed to the boiler tube wall holding member with through hole, a plate and a through the through-hole by anchoring element , Such plates and protective systems are used in incinerators for protecting boiler tube walls from flue gas.

Eine derartige Platte und ein derartiges System sind beispielsweise in der DE 40 07 662 C1 beschrieben. Das beschriebene System weist in horizontaler Reihe an der Kesselrohrwand angeschweißte Haltelemente auf, auf die die Platten abgestützt sind. Aufgrund der Dicke des Halteelements verbleibt somit stets ein horizontaler Spalt zwischen zwei vertikal übereinander angeordneten Platten. Jede Platte wird auf dem Halteelement durch ein Verankerungselement gehalten. Dabei greift das Verankerungselement in eine Aussparung an einer Seite der Platte ein. Beim Einbau der Platte befindet sich das Verankerungselement bereits in einer Durchgangsbohrung des Halteelements, wobei die Platte so eingesetzt wird, dass das Verankerungselement in die Ausnehmung eingreift. Um die Platte an der Kesselrohrwand zu halten, wird sie mittels Mörtel an der Wand befestigt. Ebenfalls werden die Spalten zwischen den Platten und die Aussparungen der Platten mit Mörtel gefüllt.Such a plate and such a system are for example in the DE 40 07 662 C1 described. The system described has in a horizontal row welded to the boiler tube wall holding elements on which the plates are supported. Due to the thickness of the retaining element thus always remains a horizontal gap between two vertically stacked plates. Each plate is held on the support member by an anchoring element. In this case, the anchoring element engages in a recess on one side of the plate. When installing the plate, the anchoring element is already in a through hole of the holding element, wherein the plate is inserted so that the anchoring element engages in the recess. To hold the plate to the boiler tube wall, she is using mortar attached to the wall. Also, the gaps between the plates and the recesses of the plates are filled with mortar.

Neben einem hohen Montageaufwand, der durch die zwingend notwendige Vermörtelung der Platte bedingt wird, ist an dem bekannten System ferner nachteilig, dass die Montage sehr präzise durchgeführt werden muss. So müssen alle eine Platte tragenden Halteelemente auf exakt der gleichen Höhe angebracht werden, damit die Platte nach dem Einbau nicht schräg steht. Das erfordert, dass die Schweißarbeiten zur Befestigung der Halteelemente sehr präzise durchgeführt werden müssen. Außerdem bestehen erhebliche Teile der Außenfläche des Schutzsystems aus Mörtel, insbesondere die gefüllten Spalte zwischen den Platten. Da der Mörtel poröser als der gebrannte Stein ist, neigt er schneller zur Erosion und Absprengung. Ebenso nachteilig ist, dass die Platte fest mit der Rohrwand verbunden ist und damit keine Möglichkeit zur Bewegung, insbesondere zur Dehnung, hat. Damit entstehen durch Temperaturwechsel Spannungen in der Platte, die zur frühzeitigen Beschädigung der Platte führen.In addition to a high assembly cost, which is due to the mandatory mortaring of the plate is also disadvantageous in the known system that the assembly must be carried out very precisely. Thus, all holding a plate supporting elements must be mounted at exactly the same height, so that the plate is not inclined after installation. This requires that the welding work for fixing the holding elements must be carried out very precisely. In addition, considerable parts of the outer surface of the protection system are made of mortar, in particular the filled gaps between the plates. As the mortar is more porous than the burned stone, it tends to erosion and blasting faster. It is also disadvantageous that the plate is firmly connected to the pipe wall and thus has no possibility for movement, in particular for stretching. This creates tensions in the plate due to temperature changes, which lead to premature damage to the plate.

WO 00/57106 A offenbart eine Platte für ein Schutzsystem für eine Kesselwand wobei an der Rückseite eine Ausnehmung zur Aufnahme eines Halteelements vorgesehen ist. WO 00/57106 A discloses a plate for a protection system for a boiler wall wherein a recess for receiving a holding element is provided on the back.

Der Erfindung liegt das technische Problem zugrunde, das bekannte Schutzsystem zu vereinfachen und standfester zu machen.The invention is based on the technical problem of simplifying the known protection system and making it more stable.

Dieses Problem wird durch eine Platte für ein Schutzsystem für eine Kesselrohrwand mit einer Rückseite, einer Vorderseite und die Rückseite und Vorderseite verbindende Seiten gelöst, wobei

  • an der Rückseite eine Ausnehmung zur Aufnahme eines Halteelements vorgesehen ist und
  • eine Bohrung von einer Seite zur Ausnehmung führt.
This problem is solved by a plate for a boiler tube wall protection system having a back side, a front side and rear side and front side connecting sides, wherein
  • on the back of a recess for receiving a retaining element is provided and
  • a bore from one side leads to the recess.

Besondere Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Particular embodiments of the invention are described in the subclaims.

Die erfindungsgemäße Platte weist an ihrer Rückseite eine Ausnehmung zur Aufnahme eines Halteelements auf. In einem Schutzsystem eingebaut wird die Platte somit nicht mit ihrer unteren Seite auf dem Halteelement abgestützt sondern wird mit der Ausnehmung auf das Halteelement aufgehängt. Das Halteelement ist durch die Platte vollständig vom Rauchgas geschützt. Ferner verbleiben bei mehreren neben- bzw. übereinander eingebauten Platten keine Spalte durch die Halteelemente. Die Platten können ohne Spalt direkt aneinander gesetzt werden, so dass zwischen den Platten entweder gar kein oder nur sehr wenig Mörtel- oder Fugenfüllmaterial zur Spaltfüllung eingesetzt wird. Dadurch wird die Standfestigkeit des Schutzsystems erhöht.The plate according to the invention has on its rear side a recess for receiving a holding element. Installed in a protective system, the plate is thus not supported with its lower side on the support member but is hung with the recess on the support member. The holding element is completely protected by the plate from the flue gas. Furthermore, in the case of several plates installed side by side or one above the other, no gaps remain through the holding elements. The plates can be placed directly against each other without a gap, so that between the plates either no or only very little mortar or joint filling material is used for gap filling. This increases the stability of the protection system.

Ferner weist die erfindungsgemäße Platte eine Bohrung auf, die von einer Seite zur Ausnehmung führt. Diese Bohrung dient beim Einbau der Platte der Einführung eines Verankerungselements, das die Platte an dem Halteelement verankert. Da das Verankerungselement von einer Seite aus eingeführt wird, verbleibt eine vollflächige Vorderseite, die im Kontakt mit dem Rauchgas steht. Selbst wenn die Bohrung im eingebauten Zustand mit Mörtel aufgefüllt wird, ist dieser Mörtel nicht im direkten Kontakt mit dem Rauchgas. Die Platten können direkt aufeinander aufliegend eingebaut werden, so dass kein Spalt verbleibt, durch den Rauchgas von der Vorderseite entlang der Seiten strömen könnte.Furthermore, the plate according to the invention has a bore which leads from one side to the recess. This hole is used when installing the plate of the introduction of an anchoring element that anchors the plate to the support member. Since the anchoring element is inserted from one side, a full-surface front remains in contact with the flue gas. Even if the hole in the built Condition is filled with mortar, this mortar is not in direct contact with the flue gas. The plates can be installed directly superposed so that there is no gap through which flue gas could flow from the front along the sides.

Im Rahmen der vorliegenden Beschreibung der Erfindung wird unter einer Platte jeglicher Körper verstanden, der in Schutzsystemen von Kesselrohrwänden zum Schutz der Kesselrohrwände verwendet wird, nämlich jeglicher Körper, der auf der rauchgaszugewandten Seite der Kesselrohrwand zu deren Schutz vor Rauchgas angebracht wird. Dies sind insbesondere Steine aus feuerfesten Werkstoffen.In the present description of the invention, a plate means any body used in boiler tube wall protection systems to protect the boiler tube walls, namely any body placed on the flue gas side of the boiler tube wall for protection against flue gas. These are in particular stones made of refractory materials.

Die Platte kann jegliche beliebige Form haben. Wesentlich ist, dass sie eine definierte Rückseite hat, die im Einbauzustand der Kesselrohrwand zugewandt ist und in die eine Ausnehmung eingebracht werden kann, in der das Halteelement im Einbauzustand durch die Platte von Rauchgaskontakt geschützt wird. Vorderseite und Seiten können beliebig gestaltet sein und nahtlos ineinander übergehen. Vorderseite und Seiten der Platte unterscheiden sich von der Rückseite dadurch, dass sie im Einbauzustand der Kesselrohrwand nicht zugewandt sind. Ihre Form wird durch den Einbauort der Platte bestimmt. Wesentlich ist, dass eine Seite vorgesehen ist, die im Einbauzustand nicht im direkten Kontakt mit dem Rauchgas steht, in die die Bohrung eingebracht wird. Vorzugsweise ist die Platte ein flacher Körper mit einer flachen Vorderseite, senkrecht zu der Vorderseite stehenden, flachen Seiten und einer Rückseite. Dabei ist die Fläche der Vorderseite in der Regel größer als die Fläche einer Seite. Besonders bevorzugt hat die Vorderseite eine rechteckige Form. Denkbar sind aber auch andere Formen (z. B. hexagonale, dreieckige oder oktogonale Formen.The plate can have any shape. It is essential that it has a defined back, which faces in the installed state of the boiler tube wall and into which a recess can be introduced, in which the holding element is protected in the installed state by the plate of flue gas contact. Front and sides can be designed in any way and seamlessly merge. The front and sides of the plate differ from the rear in that they are not facing the boiler tube wall when installed. Their shape is determined by the location of the plate. It is essential that a side is provided which is not in direct contact with the flue gas in the installed state, in which the bore is introduced. Preferably, the plate is a flat body having a flat front side, flat sides perpendicular to the front side, and a back side. Here is the area of the front in the Usually larger than the area of a page. Particularly preferably, the front side has a rectangular shape. However, other shapes are also conceivable (eg hexagonal, triangular or octagonal shapes.

Als Ausnehmung wird jede Konturgebung der Rückseite der Platte verstanden, die ein Einhängen der Platte auf ein von einer Kesselrohrwand abstehendes Halteelement erlaubt. Einhängen bedeutet das Aufstecken der Platte mit ihrer Ausnehmung auf ein Halteelement. Dieses kann, je nach Einbaulage der Platte, von einer senkrechten oder in einem Winkel zur Senkrechten stehenden Kesselrohrwand abstehen. Vorzugsweise hat die Ausnehmung in den Ebenen parallel zur Vorderfläche einen rechteckigen Querschnitt, wobei besonders bevorzugt die an die Rückseite angrenzenden, die Ausnehmung begrenzenden Flächen senkrecht zur Vorderseite verlaufen.As a recess, any contouring of the back of the plate is understood, which allows mounting of the plate on a protruding from a boiler tube wall holding element. Hooking means plugging the plate with its recess on a holding element. This can, depending on the mounting position of the plate, protrude from a vertical or at an angle to the vertical boiler tube wall. Preferably, the recess in the planes parallel to the front surface has a rectangular cross-section, wherein particularly preferably the areas adjacent to the back, the recess defining surfaces perpendicular to the front.

Als Bohrung wird jeder Durchbruch der Platte von einer Seite zur Ausnehmung verstanden. Dies kann ein durch tatsächliches Bohren in den Stein erzeugter Durchgang sein. Es kann beispielsweise aber auch eine bereits bei der Herstellung der Grundform der Platte hergestellter Durchlass sein. Wesentlich ist, dass die Bohrung das Durchschieben eines Verankerungselements von der Seite zur Ausnehmung ermöglicht.As drilling every breakthrough of the plate is understood from one side to the recess. This can be a passage created by actual drilling in the stone. However, it can also be, for example, a passage already produced in the production of the basic shape of the plate. It is essential that the bore allows the passage of an anchoring element from the side to the recess.

Bei der erfindungsgemäßen Platte wird eine besonders gute Stabilität einer aus diesen Platten zusammengesetzten Schutzwand für eine Kesselrohrwand erreicht, wenn eine Seite im einem Winkel von weniger als 90°, beziehungsweise von mehr als 270° zur Vorderseite ausgerichtet ist, insbesondere in einem Winkel von 45° bzw. 315°. Beim Einbau der Platten wird jeweils die abgeschrägte Seite auf eine andere, entgegengesetzt abgeschrägte Seite aufgesetzt, so dass diese abgeschrägten Seiten plan aufeinander liegen. Insbesondere bei Platten, die an der oberen und unteren Seite angeschrägt sind, stützen sich die Platten gegenseitig und wirken einer Rotation der Platte entgegen. Ferner wird durch die Abschrägung der Einbau der Platten vereinfacht. Alternativ zu einer solchen Gärungsfuge können die Platten auch über eine stufenförmige Fuge teilweise überlappend angeordnet sein.In the plate according to the invention a particularly good stability of a composite wall composed of these panels is achieved for a boiler tube wall when one side at an angle of less than 90 °, or more than 270 ° to Front is aligned, in particular at an angle of 45 ° or 315 °. When installing the plates, the chamfered side is in each case placed on another, opposite bevelled side, so that these bevelled sides lie flat on one another. In particular, in plates which are beveled on the upper and lower sides, the plates mutually support and counteract a rotation of the plate. Furthermore, the inclination of the installation of the plates is simplified. As an alternative to such a fermentation joint, the plates can also be arranged partially overlapping over a stepped joint.

Ebenso können die Seiten als im wesentlichen senkrecht zur Vorderseite verlaufende Flächen ausgebildet werden. Die Stabilitätsvorteile und Leichtigkeit des Ein- und Ausbaus der Platte, wie sie bei Platten mit abgeschrägten Seiten erreicht werden, können bei Platten mit senkrecht zur Vorderseite verlaufenden Seiten erreicht werden, wenn diese Seiten eine im wesentlichen parallel zur Vorderseite verlaufende Stufe aufweisen. Ähnlich, wie die gewinkelten Seiten zur Stabilisierung und Positionierung der Platte ineinander greifen, greifen auch Platten mit abgestuften Seiten ineinander.Likewise, the sides may be formed as surfaces extending substantially perpendicular to the front. The stability advantages and ease of installation and removal of the panel, as achieved in slanted-panel panels, can be achieved in panels having sides perpendicular to the front when these sides have a step substantially parallel to the front. Similarly, as the angled sides interlock to stabilize and position the plate, plates with stepped sides also interlock.

Der Wärmeübergang zwischen dem Rauchgas und der Flüssigkeit in den Rohren der Kesselrohrwand wird verbessert, je dichter die Platte an der Kesselrohrwand anliegt und je schmaler der Spalt zwischen Platte und Kesselrohrwand ist. Deshalb ist es von Vorteil, wenn die Rückseite der Platte an die Form einer Kesselrohrwand angepasst ist, insbesondere halbzylindrische Bereiche für die Rohre und Flächen für die die Rohre verbindenden Rohrflossen, aufweist.The heat transfer between the flue gas and the liquid in the tubes of the boiler tube wall is improved, the closer the plate rests against the boiler tube wall and the narrower the gap between the plate and the boiler tube wall. Therefore, it is advantageous if the back of the plate to the shape of a Boiler pipe wall is adapted, in particular semi-cylindrical regions for the pipes and surfaces for connecting the pipes pipe fins, has.

Die Platte kann eine Sackbohrung aufweisen, die von der Ausnehmung fortführt.The plate may have a blind bore which continues from the recess.

Erfindungsgemäß wird zur Lösung des Problems ein Schutzsystem für eine Kesselrohrwand mit einem an der Kesselrohrwand befestigten Halteelement mit Durchgangsbohrung, einer Platte und einem durch die Durchgangsbohrung durchgreifenden Verankerungselement derart ausgebildet, dass die Platte an der der Kesselrohrwand zugewandten Rückseite eine das Halteelement aufnehmende Ausnehmung aufweist, dass die Platte eine Bohrung aufweist, die von einer Seite der Platte zur Ausnehmung führt, und dass ein Ende des Verankerungselements in die Bohrung ragt.According to the invention, a protective system for a boiler tube wall with a fixed to the boiler tube wall holding member with through hole, a plate and a through the through hole anchoring element is designed such that the plate on the boiler tube wall facing the rear side has a holding element receiving recess that the plate has a bore which leads from one side of the plate to the recess, and that one end of the anchoring element projects into the bore.

Halteelemente im Sinne der Erfindung sind jegliche Elemente, die an einer Kesselrohrwand befestigt werden können und die eine mit ihrer Ausnehmung auf sie geschobene Platte tragen können, wenn diese Platte durch ein Verankerungselement in einer Durchgangsbohrung dieses Elements verankert wird. Insbesondere sind die Halteelemente flache, prismenförmige, längliche Stähle, die auf die Kesselrohrwand (Stege) aufgeschweißt werden. Vor allem können die Stähle rechteckige Oberflächen haben, sie können aber auch an zwei einander gegenüberliegenden oder mehreren gegenüberliegenden Flächen trapezförmige Oberflächen haben. Das Haltelement ist bevorzugt an Rohrflossen angebracht, die zwischen den Rohren der Kesselrohrwand angeordnet sind. Insbesondere ist die Längsachse des Halteelements senkrecht zur Oberfläche der Kesselrohrwand, insbesondere der Rohrflosse, angeordnet.Holding elements according to the invention are any elements that can be attached to a boiler tube wall and can carry a pushed with their recess on them plate when this plate is anchored by an anchoring element in a through hole of this element. In particular, the holding elements are flat, prism-shaped, elongated steels, which are welded onto the boiler tube wall (webs). Above all, the steels may have rectangular surfaces, but they may also have trapezoidal surfaces on two opposite or more opposite surfaces. The holding element is preferably attached to pipe fins, which between the pipes of the Boiler tube wall are arranged. In particular, the longitudinal axis of the holding element is arranged perpendicular to the surface of the boiler tube wall, in particular of the tube fin.

Die Vorteile der Erfindung werden bei Schutzsystemen erreicht, die nur eine Platte aufweisen. In der Regel wird eine Kesselrohrwand jedoch durch eine Wand von übereinander und nebeneinander angeordneten Platten geschützt. Hier werden die erfindungsgemäßen Vorteile besonders dann erzielt, wenn alle Platten des Schutzsystems nach dem erfindungsgemäßen Prinzip an der Kesselrohrwand befestigt werden. Die Platten können direkt, ohne wesentlichen Spalt auf- und nebeneinander gesetzt sein. Sie können aber auch mit Spalt gesetzt sein. Der möglicherweise bestehende Spalt zwischen den Platten, der Spalt zwischen einer Platte und der Kesselrohrwand, die Bohrung, sowie die Ausnehmung können zur Verbesserung des Wärmeübergangs und des Schutzes vor Rauchgas mit Mörtel gefüllt sein. Dabei können die Platten im montierten Zustand auch mit Beton oder Mörtel hintergossen werden. Möglich ist jedoch auch eine mörtelfreie Verlegung.The advantages of the invention are achieved in protection systems which have only one plate. As a rule, however, a boiler tube wall is protected by a wall of plates arranged one above the other and next to one another. Here, the advantages of the invention are particularly achieved when all plates of the protection system are attached to the principle of the invention on the boiler tube wall. The plates can be directly, without significant gap up and next to each other. But they can also be set with a gap. The possibly existing gap between the plates, the gap between a plate and the boiler tube wall, the bore, as well as the recess may be filled with mortar to improve the heat transfer and the protection against flue gas. The panels can also be poured in the assembled state with concrete or mortar. However, a mortar-free installation is also possible.

In besonders vorteilhafter Weise ist der Querschnitt der Ausnehmung in jeder Ebene senkrecht zur Längsachse des Halteelements um ein Vielfaches größer, als der Querschnitt des Halteelements in der gleichen Ebene. Besonders bei einer quaderförmiger Ausnehmung ist die Fläche eines durch an die Rückseite angrenzende Begrenzungsflächen der Ausnehmung umfassten Rechtecks um ein Vielfaches größer, als der in der gleichen Ebene liegende Querschnitt des Halteelements. Dies ermöglicht es, dass das Haltelement nicht genau an der Sollposition auf der Kesselrohrwand angebracht werden muss. Auch bei einem etwas neben der Sollposition angebrachten Halteelement lässt sich bei dieser besonderen Ausgestaltung des Systems die Platte ohne weiteres auf das Halteelement aufschieben. Insbesondere bevorzugt hat die Ausnehmung die gleiche Breite wie ein flach ausgebildetes Haltelement, jedoch ist die Ausnehmung länger, als die Dicke des Haltelements. Die Platte kann dann, auf das Haltelement aufgeschoben, senkrecht zur Längsachse des Halteelements in Längsrichtung der Ausnehmung in die gewünschte Position geschoben werden. Bevorzugt ist die so definierte Fläche der Ausnehmung um mehr als das eineinhalbfache, insbesondere um mehr als das dreifache größer als der Querschnitt des Halteelements.In a particularly advantageous manner, the cross section of the recess in each plane perpendicular to the longitudinal axis of the holding element is greater by a multiple than the cross section of the holding element in the same plane. Particularly in the case of a cuboid recess, the area of a rectangle encompassed by boundary surfaces of the recess adjoining the rear side is many times greater than the cross section of the retaining element lying in the same plane. this makes possible that the holding element does not have to be mounted exactly at the desired position on the boiler tube wall. Even with a slightly attached next to the target position holding element can be in this particular embodiment of the system, the plate easily pushed onto the support member. Particularly preferably, the recess has the same width as a flat formed holding element, however, the recess is longer than the thickness of the holding element. The plate can then be pushed onto the holding element, are pushed perpendicular to the longitudinal axis of the holding member in the longitudinal direction of the recess in the desired position. Preferably, the thus defined surface of the recess is more than one and a half times, in particular more than three times larger than the cross section of the holding element.

Der Halt der Platte an dem Halteelement wird verbessert, wenn eine Sackbohrung von der Ausnehmung fortführt und ein weiteres Ende des Verankerungselements in die Sackbohrung ragt. Insbesondere bei stiftförmig ausgebildeten Verankerungselementen kann das Verankerungselement durch die Bohrung der Platte und die Durchgangsbohrung des Halteelements bis in die Sackbohrung vorgeschoben werden. Dadurch wird eine stabile Verankerung erzielt, da das Verankerungselement an beiden Enden in der Platte steckt. In besonders vorteilhafter Weise wird ein zylindrisch oder konisch ausgebildeter Stift eingesetzt. Hierdurch wird ein besonders guter Sitz des Stiftes in der Sackbohrung gewährleistet. Das Verankerungselement kann beispielsweise aus Metall oder Keramik hergestellt sein.The retention of the plate on the holding element is improved when a blind bore of the recess continues and another end of the anchoring element projects into the blind bore. In particular, in the case of pin-shaped anchoring elements, the anchoring element can be advanced through the bore of the plate and the through hole of the holding element into the blind bore. As a result, a stable anchoring is achieved, since the anchoring element is inserted at both ends in the plate. In a particularly advantageous manner, a cylindrical or conical pin is used. As a result, a particularly good fit of the pin is ensured in the blind hole. The anchoring element may be made of metal or ceramic, for example.

Die Stabilität der Verankerung ist besonders groß, wenn das Verankerungselement keilförmig ausgebildet ist.The stability of the anchoring is particularly great when the anchoring element is wedge-shaped.

Nachfolgend wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung erläutert. Darin zeigt

The invention will be explained with reference to a drawing illustrating only one embodiment. It shows
Fig. 1
a protection system for a boiler tube wall with a plate in a perspective, partially sectioned view and
Fig. 2
the protection system of Fig. 1 in an exploded view.

Eine Platte 1 ist über ein Verankerungselement 2 mit einem Halteelement 3 verbunden. Das Haltelement 3 ist auf die Rohrflosse 4 einer Kesselrohrwand 5 aufgeschweißt. Das Halteelement 3 sitzt in einer Ausnehmung 6 der Platte 1. Das Verankerungselement 2 steckt in einer im Bereich der Ausnehmung 6 in dem Halteelement 3 angeordneten Durchgangsbohrung 7. Ein Ende 2a des Verankerungselements 2 ragt in eine Bohrung 8, die von der Ausnehmung 6 zu einer Seite 9 der Platte 1 führt. Das andere Ende 2b des stiftartig ausgebildeten Verankerungselements 2 ragt in eine Sackbohrung 10, die von der Ausnehmung 6 fortführt.A plate 1 is connected via an anchoring element 2 with a holding element 3. The holding element 3 is welded onto the tube fin 4 of a boiler tube wall 5. The holding element 3 is seated in a recess 6 of the plate 1. The anchoring element 2 is inserted in a arranged in the region of the recess 6 in the holding element 3 through hole 7. One end 2a of the anchoring element 2 protrudes into a bore 8, from the recess 6 to a Page 9 of the plate 1 leads. The other end 2b of the pin-like anchoring element 2 protrudes into a blind bore 10, which continues from the recess 6.

Die Platte 1 weist eine Vorderseite 11, eine Rückseite 12 sowie neben der Seite 9 weitere die Vorderseite 11 und Rückseite 12 verbindende Seiten 9a,9b auf (die Seite 9c ist in der Fig. 2 zu erkennen). Die Rückseite 12 ist an die Form der Kesselrohrwand 5 angepasst. Sie weist für die Rohre 13 halbzylinderförmige Bereiche 14 auf und eine Fläche 15, die an die Form der Rohrflosse 4 angepasst ist. Die Seiten 9,9a,9b,9c bestehen aus senkrecht zur Vorderseite 11 verlaufenden Flächen 16,17 und einer zur Vorderseite 11 im wesentlichen parallelen Stufe 18. Die Übergange zwischen den Flächen 16,17 und der Stufe 18 sind abgerundet. Wie in Fig. 2 ersichtlich ist die Stufe 18 an zwei Seiten 9b,9c der Platte 1 von der Vorderseite 11 gesehen zur Plattenmitte hin und an den diesen Seiten 9b,9c gegenüberliegenden Seiten 9,9a von der Plattenmitte fort ausgerichtet.The plate 1 has a front side 11, a back side 12 and, in addition to the side 9, further sides 9a, 9b connecting the front side 11 and back side 12 (the side 9c can be seen in FIG. 2). The backside 12 is adapted to the shape of the boiler tube wall 5. It has for the tubes 13 semi-cylindrical portions 14 and a surface 15 which is adapted to the shape of the tube fin 4. The sides 9,9a, 9b, 9c consist of perpendicular to the front surface 11 extending surfaces 16,17 and one to the front 11 substantially parallel stage 18. The transitions between the surfaces 16,17 and the step 18 are rounded. As can be seen in Fig. 2, the step 18 on two sides 9b, 9c of the plate 1 as viewed from the front 11 toward the center of the plate and on the sides 9,9a opposite these sides 9b, 9c are oriented away from the center of the plate.

Das Halteelement 3 ist als flacher, länglicher Steg ausgebildet, dessen Längsachse senkrecht zur Rohrflosse 4 und damit der Kesselrohrwand 5 ausgerichtet ist. An seinem äußeren Ende ist das Haltelement 3 abgerundet.The holding element 3 is formed as a flat, elongated web whose longitudinal axis is aligned perpendicular to the pipe fin 4 and thus the boiler tube wall 5. At its outer end, the holding element 3 is rounded.

Die Fläche der Ausnehmung 6 hat in einer zur Vorderseite 11 parallelen Ebene, durch an die Rückseite 12 angrenzende Begrenzungsflächen begrenzt die Form eines Rechtecks. An das äußere Ende des Halteelements 3 angepasst ist der Grund der Ausnehmung 6 halbzylindrisch ausgebildet. Die Breite B der Ausnehmung 6 ist unwesentlich größer als die Breite B des Halteelements 3, um ein einfaches Einführen des Halteelements 3 in die Ausnehmung 6 zu ermöglichen. Jedoch ist die Länge L der Ausnehmung um ein Vielfaches größer als die Dicke d des Halteelements 3.The surface of the recess 6 has in a plane parallel to the front 11, bounded by the rear side 12 adjacent boundary surfaces the shape of a rectangle. Adapted to the outer end of the retaining element 3, the base of the recess 6 is formed semi-cylindrical. The width B of the recess 6 is insignificantly greater than the width B of the holding member 3, to allow easy insertion of the holding member 3 in the recess 6. However, the length L of the recess is many times greater than the thickness d of the holding element. 3

Zur Montage der Platte 1 wird diese so auf das Halteelement 3 gehängt, dass das Halteelement 3 in die Ausnehmung 6 eingeführt wird. Dabei sitzt die Platte 1 mit ihrer unteren Seite 9b auf der oberen Seite der nächst unteren, nicht dargestellten Platte und mit ihrer rechten Seite 9c auf der linken Seite der nächst rechten, ebenfalls nicht dargestellten Platte auf. Die in den Seiten der Platten ausgebildeten Stufen führen zu einem passgenauen Sitz der Platten. Dabei kann das Halteelement 3 jedoch etwas oberhalb oder unterhalb der gewünschten Position auf der Rohrflosse 4 angebracht sein. Denn auch neben der gewünschten Position kann das Halteelement 3 aufgrund der vielfach größeren Länge L der Ausnehmung 6 im Verhältnis zur Dicke d des Halteelements 3 gut in die Ausnehmung 6 eingeführt werden. Ein Versatz des Halteelements 3 in rechte oder linke Richtung tritt nicht auf, da die Breite B des Halteelementes 3 dem Zwischenraum zwischen den Rohren 13 der Kesselrohrwand 5 entspricht und damit in seiner Position durch diese begrenzt wird. Die auf den benachbarten Platten aufsitzende Platte 1 wird durch Einführen des Verankerungselements 2 in die Bohrung 8 und anschließendem Durchstoßen der Durchgangsbohrung 7 sowie dem Einführen in die Sackbohrung 10 fest mit dem Halteelement 3 und damit mit der Kesselrohrwand 5 verbunden.To mount the plate 1, this is hung on the holding element 3 so that the holding element 3 is inserted into the recess 6. The plate sits 1 with its lower side 9b on the upper side of the next lower plate, not shown, and with its right side 9c on the left side of the next right, also not shown plate on. The steps formed in the sides of the plates lead to a snug fit of the plates. However, the holding element 3 may be mounted slightly above or below the desired position on the pipe fin 4. For in addition to the desired position, the holding element 3 can be well inserted into the recess 6 due to the much greater length L of the recess 6 in relation to the thickness d of the holding element 3. An offset of the holding element 3 in the right or left direction does not occur, since the width B of the holding element 3 corresponds to the gap between the tubes 13 of the boiler tube wall 5 and thus limited in its position by this. The seated on the adjacent plates plate 1 is connected by inserting the anchoring element 2 in the bore 8 and then piercing the through hole 7 and the insertion into the blind bore 10 fixed to the support member 3 and thus to the boiler tube wall 5.

Anstelle auf der jeweils unteren Platte aufzusitzen kann bei vertikaler Einbaulage die Platte 1 bei der Montage auch auf dem Halteelement 3 aufgehängt werden. Dann sitzt die in Längsrichtung L obere, begrenzende Fläche der Ausnehmung 6 auf der oberen Fläche des Halteelements 3 auf (vgl. Fig.1). Der möglicherweise zwischen der so auf dem Halteelement 3 aufgehängten Platte 1 und der nächst unteren Platte verbleibende Spalt wird mit Mörtel gefüllt.Instead of sitting on the respective lower plate, the plate 1 can also be hung on the holding element 3 during assembly in a vertical mounting position. Then, the upper, limiting surface of the recess 6 in the longitudinal direction L sits on the upper surface of the retaining element 3 (see FIG. The possibly remaining between the so hung on the support member 3 plate 1 and the next lower plate remaining gap is filled with mortar.
