Description
Die vorliegende Erfindung betrifft einen Rohrwandschutz für eine Kesselrohrwand aus einer Vielzahl von im Wesentlichen parallel verlaufenden Rohren, die durch parallel zu den Rohren verlaufende Stege miteinander verbunden sind, mit wenigstens einem Wandelement aus feuerfestem Material, wobei das Wandelement einseitig an der Kesselrohrwand angebracht ist.The The present invention relates to a pipe wall protection for a boiler pipe wall from a plurality of substantially parallel tubes, the connected by running parallel to the tubes webs are, with at least one wall element of refractory material, wherein the wall element is attached to one side of the boiler tube wall.

Ausgehend vom Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Rohrwandschutz der eingangs beschriebenen Art bereitzustellen, der ohne mechanische Hilfsmittel an der Kesselrohrwand auskommt und an einer Seite der Rohrwand befestigt werden kann.outgoing The object of the present invention is the object of the prior art basis to provide a pipe wall protection of the type described above, which works without mechanical aids on the boiler tube wall and can be attached to one side of the pipe wall.
Diese Aufgabe wird dadurch gelöst, dass zwischen dem Wandelement und den Rohren der Kesselrohrwand eine Schicht aus Kleber zum Halten des Wandelements ohne zusätzliche mechanische Befestigungsvorrichtungen vorgesehen ist.These Task is solved by that between the wall element and the pipes of the boiler tube wall a layer of adhesive for holding the wall element without additional mechanical fastening devices is provided.
Erfindungsgemäß ist erkannt worden, dass durch die Verwendung eines geeigneten Klebers ein Wegfall der mechanischen Befestigungsvorrichtungen erreicht werden kann. Der Kleber kann entweder eine hohe oder eine geringe Wärmeleitfähigkeit aufweisen. Eine hohe Wärmeleitfähigkeit ergibt sich dann, wenn der Kleber Siliziumcarbid enthält, während sich eine geringe Wärmeleitfähigkeit bei Verwendung von Aluminiumoxid als Bestandteil des Klebers ergibt. Der Kleber ist ferner temperaturbeständig sowie gasdicht gegenüber korrosiven Gasen, die die Rohrwand selber beschädigen können. Außerdem weist der Kleber eine hinreichend hohe Adhäsion auch bei hohen Temperaturen auf, so dass auch beim Betrieb des Kessels die Wandelemente sicher an der Kesselrohrwand haften.According to the invention is recognized have been eliminated by the use of a suitable adhesive the mechanical fastening devices can be achieved. The adhesive can have either a high or a low thermal conductivity exhibit. A high thermal conductivity arises when the adhesive contains silicon carbide while a low thermal conductivity when using alumina as a component of the adhesive results. The adhesive is also temperature resistant and gas-tight against corrosive Gases that can damage the pipe wall itself. In addition, the adhesive has a sufficiently high adhesion even at high temperatures, so even during operation of the boiler the wall elements adhere securely to the boiler tube wall.
Durch den Wegfall der Halter, die an der Kesselrohrwand vorsehen sein müssten und selber vor hohen Temperaturen geschützt werden müssten, ist es nunmehr möglich, die Wandelemente dünner auszubilden. Dies führt zu einer Materialeinsparung und damit auch zu einer Gewichtseinsparung. Außerdem lässt sich der erfindungsgemäße Rohrwandschutz leicht montieren und gegebenenfalls reparieren.By the elimination of the holder, which must be provided on the boiler tube wall would and even have to be protected from high temperatures, it is now possible, the wall elements thinner train. this leads to to a material saving and thus also to a weight saving. In addition, can be the pipe wall protection according to the invention easily assemble and repair if necessary.
In einer bevorzugten Ausführungsform handelt es sich bei dem Kleber um einen anorganischen Kleber, insbesondere um einen keramisch-monolithischen Werkstoff. Dieser weist die für diese spezielle Anwendung notwendigen Eigenschaften auf.In a preferred embodiment the adhesive is an inorganic adhesive, in particular a ceramic-monolithic material. This one has the for this special application necessary properties.
In einer weiteren bevorzugten Ausführungsform weist die Schicht senkrecht zur Kesselrohrwand gemessen eine im Wesentlichen konstante Dicke auf, was dazu führt, dass über die gesamte Schicht gesehen ein gleichmäßiger Wärmefluss erfolgt. Weist das Wandelement ebenfalls eine konstante Dicke auf, so gilt dies für den Rohrwandschutz als Ganzes. Insgesamt ergibt sich dann eine gleichmäßige thermische Belastung des Rohrwandschutzes.In a further preferred embodiment has the layer measured perpendicular to the boiler tube wall in the Substantially constant thickness, which causes it to be seen over the entire layer a uniform heat flow he follows. If the wall element also has a constant thickness, this is true for the pipe wall protection as a whole. Overall, then results in a uniform thermal Load on the pipe wall protection.
In einer weiteren bevorzugten Ausführungsform weist das Wandelement Distanzhalter auf, die die Montage des Wandelements auf einen vorbestimmten Abstand zur Kesselrohrwand erleichtern. Sind an einem Wandelement wenigstens zwei Distanzhalter vorgesehen, so ist die relative Position zur Kesselrohrwand festgelegt.In a further preferred embodiment has the wall element spacers on which the mounting of the wall element facilitate to a predetermined distance to the boiler tube wall. are provided on a wall element at least two spacers, so the relative position to the boiler tube wall is determined.
Bevorzugterweise sind die Distanzhalter mit einem halbkreisförmigen Querschnitt versehen, was eine einfache Herstellung ermöglicht.preferably, the spacers are provided with a semicircular cross section, which allows easy production.
Vorzugsweise sind an den Wandelementen Halbschalen ausgebildet, die an die Form der Rohre der Kesselrohrwand angepasst sind. Somit lässt sich in einfacher Weise realisieren, dass die Schichten aus Kleber und feuerfestem Material über die gesamte Rohrwand gesehen gleichmäßig stark sind. In einer weiteren bevorzugten Ausführungsform weisen die Wandelemente mehrere Halbschalen auf, so dass ein Wandelement mehrere Rohre abdeckt.Preferably Shells are formed on the wall elements half-shells, which conform to the shape the pipes of the boiler tube wall are adjusted. Thus can be in easy to realize that the layers of adhesive and fireproof Material over the entire pipe wall are uniformly strong. In another preferred embodiment the wall elements on several half-shells, so that a wall element covering several pipes.
Die Wandelemente können nebeneinander sowie in Erstreckungsrichtung der Rohre übereinander an der Kesselrohrwand angeordnet werden. So kann auf einfache Weise die gesamte Fläche der Kesselrohrwand zusammenhängend geschützt werden.The Wall elements can next to each other and in the extension direction of the tubes one above the other be arranged on the boiler tube wall. So can easily the entire area the boiler tube wall connected protected become.
Eine Fuge zwischen zwei nebeneinander angeordneten Wandelementen stellt sicher, dass auch bei einer thermischen Ausdehnung in Folge von Erwärmung keine Spannungen zwischen Rohrwandschutz und Kesselrohrwand hervorgerufen werden können.A Fugue between two juxtaposed wall elements provides sure that even at a thermal expansion due to warming no tensions between pipe wall protection and boiler tube wall caused can be.
Durch einen Vorsprung am ersten Ende des Wandelements und einer Aussparung am zweiten Ende kann sichergestellt werden, dass die Wandelemente in Erstreckungsrichtung der Rohre bündig zueinander angeordnet sind.By a projection on the first end of the wall element and a recess at the second end it can be ensured that the wall elements arranged in the direction of extension of the tubes flush with each other are.
Die vorliegende Erfindung wird im Folgenden anhand einer lediglich ein bevorzugtes Ausbildungsbeispiel darstellenden Zeichnung näher erläutert.
