RohrwandPipe wall
Die Erfindung betrifft eine Rohrwand für Umfassungswände der Brennkammern von Dampferzeugern, Wirbelschichtfeuerungen sowie für Heizflächen von Wirbelschichtfeuerungen, in denen fossiler Brennstoff verfeuert wird.The invention relates to a tube wall for the surrounding walls of the combustion chambers of steam generators, fluidized bed furnaces and for heating surfaces of fluidized bed furnaces in which fossil fuel is burned.
Derartige Rohrwände sind u.a. aus den "Mitteilungen der VGEi, Heft 83, April 1963: "Die Flossenwand, ein neues Bauelement für den modernen Hochleistungs-Dampferzeuger" bekannt geworden.Such tube walls have become known, among other things, from the "Mitteilungen der VGEi, Issue 83, April 1963: "The fin wall, a new component for the modern high-performance steam generator".
Nachteilig ist jedoch bei Rohrwänden in Rohr-Steg-Rohr-Ausführung, daß sie erosionsanfällig sind und eine geringe Festigkeit, insbesondere für Rohrquerzug und -biegung, aufweisen. Weiters treten Komplikationen mit Anschweißteilen wie Eckanlenkungen von Bandagen, Brennerkästen, Schauluken, Einsteigtüren etc. auf.However, the disadvantage of pipe walls in the pipe-web-pipe design is that they are susceptible to erosion and have low strength, especially for transverse pipe tension and bending. In addition, complications arise with welded parts such as corner joints of bandages, burner boxes, inspection hatches, access doors, etc.
Aufgabe der vorliegenden Erfindung ist es, die geschilderten Nachteile zu beseitigen.The object of the present invention is to eliminate the disadvantages described.
Diese Aufgabe wird gemäß den kennzeichnenden Merkmalen des Schutzanspruches 1 gelöst. Die Unteransprüche gestalten die Erfindung nach Anspruch 1 vorteilhaft aus.This object is achieved according to the characterizing features of claim 1. The subclaims advantageously develop the invention according to claim 1.
Durch die erfindungsgemäßen Maßnahmen ergeben sich die folgenden Vorteile:The measures according to the invention result in the following advantages:
a) einfache Herstellung,a) ease of manufacture,
b) beidseitig ebene Oberfläche,b) flat surface on both sides,
c) hohe Festigkeit,c) high strength,
d) einfache Bandagierung undd) simple bandaging and
e) problemloses Anbringen von Anschweißteilen an der Rohrwand.e) easy attachment of welded parts to the pipe wall.
Die Erfindung wird anhand der Beschreibung und der Zeichnungen näher erläutert.The invention is explained in more detail with reference to the description and the drawings.

Wärmeenergie, die durch das Verfeuern von fossilen Brennstoffen innerhalb der Brennkammern von Dampferzeugern, Wirbelschichtfeuerungen oder anderer Anlagen frei wird, wird von einem Arbeitsmittel, das die Rohre 2 einer Rohrwand 1 durchströmt, aufgenommen und einer energetischen Nutzung zugeführt.Thermal energy released by burning fossil fuels within the combustion chambers of steam generators, fluidized bed furnaces or other systems is absorbed by a working medium that flows through the tubes 2 of a tube wall 1 and is used for energy purposes.
Die Rohrwände 1 sind hierbei zu einem gasdichten Käfig oder einer Heizfläche verschweißt und können sowohl im Verdampfer- als auch im Überhitzerteil sowie im Brennkammertrichter eingesetzt werden.The tube walls 1 are welded to form a gas-tight cage or heating surface and can be used in the evaporator and superheater sections as well as in the combustion chamber funnel.
Bei der erfindungsgemäßen Ausführung der Rohrwand 1 entsprechend Fig. 2 sind die Doppelstege 4 an den Rohren 2 derart gasdicht verschweißt, daß die Außenflächen der Doppelstege 4 mit den, quer zur Längsachse der Rohrwand 1 gesehen, Außenpunkten des Rohrdurchmessers der Rohre 2 fluchten und somit beide Außenflächen der Rohrwand 1 eben ausgebildet sind.In the inventive design of the pipe wall 1 according to Fig. 2, the double webs 4 are welded to the pipes 2 in a gas-tight manner such that the outer surfaces of the double webs 4 are aligned with the outer points of the pipe diameter of the pipes 2, seen transversely to the longitudinal axis of the pipe wall 1, and thus both outer surfaces of the pipe wall 1 are flat.
Fig. 1 zeigt eine bekannte Ausführung der Rohrwand 1.Fig. 1 shows a known design of the pipe wall 1.
