Description
Die Erfindung bezieht sich auf die Abstützung von Nachheizflächen, wie Überhitzern und Vorwärmern in senkrechten Einzug-Strahlungskesseln kleiner Leistung mit an beiden Seiten des Feuerraumes angeordneten Verdampfungsheizflächen, deren das Dampfwassergemisch führende Überströmrohre von den Sammlern zu beiden Seiten der Nachheizflächen nach der Kesseltrommel verlaufen.The invention relates to the support of after-heating surfaces, such as superheaters and preheaters in vertical draw-in radiation boilers of low power with evaporative heating surfaces arranged on both sides of the furnace, their overflow pipes leading the steam-water mixture from the collectors on both sides the after-heating surfaces run after the boiler drum.
Um in solchen Strahlungskesseln für die Abstützung der Nachheizflächen ein besonderes Gerüst zu ersparen, wird vorgeschlagen, als Auflage für die Rohrpakete der Nachheizflächen konsolartig gebogene Rohre zu verwenden, die in die Wand der Überströmrohre eingesetzt und in den Umlauf des Dampfwassergemisches der Überströmrohre eingeschaltet sind.In order to support the after-heating surfaces in such radiant boilers To save a special scaffolding, it is suggested as a support for the tube packages of the after-heating surfaces to use console-like bent pipes that are inserted into the wall of the Overflow pipes used and in the circulation of the steam water mixture of the overflow pipes are switched on.
An sich ist bekannt, einzelne Rohre oder die einzelnen Windungen einer Rohrschlange durch vom Arbeitsmittel durchströmte Stützrohre zu verbinden; bei dem Erfindungsgegenstand handelt es sich um ganze Rohrpakete, die durch wenige konsolartige, gebogene Rohre abgestützt sind.It is known per se, individual tubes or the individual turns of a To connect the pipe coil by means of support pipes through which the working medium flows; in which The subject of the invention is whole pipe packages, which are replaced by a few console-like, bent tubes are supported.
Die Erfindung ist an Hand der Abb. i bis 5 näher erläutert. Es zeigt .The invention is explained in more detail with reference to FIGS. It shows .
Abb. i einen Aufriß eines Eckrohrkessels oberhalb des Feuerraumes, Abb. 2 einen Schnitt nach A-B der Abb. i, Abb. 3 einen Schnitt nach E-F der Abb. i, Abb. 4 eine Einzelheit in der Ausbildung der Konsolen, Abb. 5 eine ausschnittsweise schaubildliche Darstellung zweier Konsolen mit daraufliegender Halterung für ein Rohrpaket.Fig. I an elevation of a corner tube boiler above the combustion chamber, Fig. 2 is a section along A-B in Fig. I, Fig. 3 is a section along E-F in Fig. i, Fig. 4 a detail in the design of the consoles, Fig. 5 a section Diagrammatic representation of two consoles with a bracket on top for a Tube package.
Seitlich des Feuerraumes i sind in üblicher Weise die Feuerraumrohre (nicht dargestellt) angeordnet. Das Dampfwassergemisch dieser Feuerraumrohre wird in den Rohren 2 gesammelt und durch die Überströmrohre 3, 4 nach oben geführt, so däß es in die Kesseltrommel 5 gelangt. Vorzugsweise sind die überströmrohre 3, 4 senkrecht an den Seiten des Kessels hochgeführt. An diesen Rohren sind nun erfindungsgemäß Konsolen 6 angeordnet, auf die die Rohrpakete des Überhitzers 7 sowie der Economi:ser 8, 9, die in. entsprechenden Halterungen '1o (Abt. 5) ruhen, aufgelegt sind. Die Konsolen 6 sind aus RQ'hren gebildet, die an den Umlauf des Dampfwassergemisches angeschlossen sind und dadurch eine Kühlung erfahren. Eine Verankerung dieser Rohrpakete an den Eckenröhren i 1, i2 des Kessels ist nicht erforderlich, denn die Rohrpakete von Überhitzer 7 und. Economiser 8, 9 werden unter Vermittlung der Konsolen 6 völlig frei von den Überströmrohren 3, 4 getragen, die ihrerseits ihre Stütze in der Vielzahl der Feuerraumrohre unterhalb der Rohre 2 finden. Die gesamten Rohrpakete von Überhitzer und Fconomieer 7, 8, 9 können sich daher, ohne daß Spannungen auftreten, im Betrieb des Kessels frei dehnen. Da die Verankerungen nach den Eckrohren 11, 12 im Fall eines Eckrohrkessels wegfallen, werden auch diese Rohre von schädlichen Spannungen völlig freigehalten und können dementsprechend gegenüber den bisher bekannten Bauarten schwächer ausgeführt werden.To the side of the combustion chamber i are the combustion chamber tubes in the usual way (not shown) arranged. The steam water mixture of these furnace tubes is collected in the pipes 2 and passed up through the overflow pipes 3, 4, so that it gets into the boiler drum 5. The overflow pipes 3, 4 are preferably Run up vertically on the sides of the boiler. These pipes are now according to the invention Consoles 6 arranged, on which the tube packages of the superheater 7 and the Economi: ser 8, 9, which rest in. Corresponding brackets' 1o (section 5) are placed. the Consoles 6 are formed from RQ'hren, which are attached to the circulation of the steam water mixture are connected and thus experience cooling. An anchoring of these pipe packages on the corner tubes i 1, i2 of the boiler is not required because the tube packages from superheater 7 and. Economisers 8, 9 are completely operated by the consoles 6 borne freely by the overflow pipes 3, 4, which in turn provide their support in large numbers of the combustion chamber tubes can be found below tubes 2. The entire superheater tube packages and Fconomieer 7, 8, 9 can therefore, without tensions occurring, during operation of the boiler can be stretched freely. Since the anchors after the corner tubes 11, 12 in the case If a corner tube boiler is omitted, these tubes are also exposed to harmful stresses kept completely free and can accordingly compared to the previously known types run weaker.
Die Kühlung der konsolartigen Rohre 6 kann in vorteilhafter Weise dadurch verbessert werden, daB die in die Rohre 3, 4 einmündenden Enden 13, 14 so abgeschrägt sind, daß durch den Umlauf des Dampfwassergemisches in den Rohren 3, 4 am unteren Ende 13 der Rohre 6 ein - Stau und am oberen Ende 14 ein Sog entsteht.The console-like tubes 6 can be cooled in an advantageous manner can be improved by the fact that the ends 13, 14 opening into the tubes 3, 4 are bevelled that by the circulation of the steam water mixture in the pipes 3, 4 at the lower end 13 of the tubes 6 - a jam and at the upper end 14 a suction occurs.
