Description

Flammrohrkessel nu«t Wasserunäufrohren Die Erfindung betrifft Flammrohrkessel. Bekannt ist es, bei solchen Kesseln für den Umlauf zwischen dem unteren und oberen Kesselraum gebogene Steigerohre außerhalb des Kessels im Rauchgasstrom der Seitenzüge anzuordnen. Diese Umlaufrohre sind wegen ihrer Beh#eizung durch die Rauchgase besonders wirksam. Ein Einwalzen. dieser Rohre in die zum Rohrdurchmesser verhältnismäßig dünne Kesselwand läßt sich aber nur in der Weise ausführen, daß die Rohre radial in den Kessel einmünden. Dadurch bilden bei sämtlichen bekannten Ausführungsformen diese gebogenen Rohre in der Nähe ihres unteren Endes Schlammsäcke. Die Schlammabsetzungen, die sieh namentlich beim Auße'rbetriebsetzen des Kessels bilden können, geben die « Möglichkeit, daß die Rohre -nach verhältnismäßig kurzer Zeit durchbrennen. Dies hatte zur Folge, daß diese außen angeordneten Umlaufrohre in der Praxib nie zur Anwendung gelangten.Flame tube boilers but not water pipes The invention relates to flame tube boilers. It is known to arrange in such boilers for the circulation between the lower and upper boiler room curved riser pipes outside the boiler in the flue gas flow of the side passes. These circulation pipes are particularly effective because they are heated by the flue gases. A rolling in. These tubes in the boiler wall, which is relatively thin to the tube diameter, can only be carried out in such a way that the tubes open radially into the boiler. As a result, in all known embodiments, these bent tubes form sacks of mud in the vicinity of their lower end. The mud depositions that can form in the boiler Auße'rbetriebsetzen look by name, enter the "possibility that the tubes -after relatively blowing a short time. As a result, these externally arranged circulation pipes were never used in practice.

Der Erfindung gemäß wird nun die Anwendung dieser Rohre unter Verringerung der erwähnten Gefährdung dadurch ermöglicht, daß die Enden der ausschließlich aufwärts abgebogenen Rohre in Muffen eingewalzt werden, weiche in die Kesselwandungen waagerecht eingeschweißt sind.According to the invention, the use of these pipes is now reduced the risk mentioned is made possible by the fact that the ends of the exclusively upward Bent pipes are rolled into sockets, soft horizontally into the boiler walls are welded.

Bei dickwandigen Trommeln hat man schon Muffen waagerecht und schräg zur Trommelwand-ung eingeschweißt, um Dampfzu- und -ableitungsrohre zu einem innenliegenden Heizkörper zu führen.Thick-walled drums already have sleeves horizontally and diagonally Welded to the drum wall, around steam supply and discharge pipes to an internal one To guide radiators.

Dies hat, insbesondere wenn nicht nur die unteren, sondern auch die oberen Enden in derartige Muffen eingeführt werden, den weiteren Vorteil, daß ein leichtes Ausivechs-elri der Rohre ermöglicht wird, weil erstens bei dieser Befestigungsart die Verbindung verhältnismäßig leicht und ohne Beschädigung der Kesselwahdung gelöst werden kann und weil weiter die beiden Rohrenden parallel zueinander ausgebildet werden können, -so daß Ein- und Ausführung der Enden in die Muffen ohne weiteres möglich ist. Diese Vorteile treffen- auch für die in die Muff-en eingewalzten Rohre zu.This has, especially if not only the lower ones, but also the ones upper ends are introduced into such sleeves, the further advantage that a easy removal of the tubes is made possible because firstly with this type of fastening the connection released relatively easily and without damaging the boiler wall can be and because further the two pipe ends are formed parallel to each other can be, -so that introduction and execution of the ends in the sleeves easily is possible. These advantages also apply to the pipes rolled into the sockets to.

Auch an den Kessel waagerecht angeflanschte Buchsen zur Einführung der unbeheizten Enden von Umlaufrohren sind be-Icannt. - Auf der Zeichnung ist eine Ausführungsform des Erfind-tingsgegenstandes dargestellt. Abb. i zeigt einen Querschnitt durch einen Kessel, Abb. 2 eine Seitenansicht mit abgebrochenem Mauerwerk.Sockets flanged horizontally to the boiler for inserting the unheated ends of circulation pipes are also known. - The drawing shows an embodiment of the subject of the invention. Fig. I shows a cross section through a boiler, Fig. 2 shows a side view with broken masonry.

Mit dem Außenmantel des Kessels i sind die Wasserumlaufrohre 2 derart verbuhden, daß sie unten unterhalb der waagerechth Kesselmittelebene dicht über der tiefsten Stelle der Kesselsohle einmünden und oben oberhalb der waagerechten Kesselmittelebene unterhalb des Wasserspiegels einmünden. Unten erfolgt der Anschluß unter Vermittlung schmiedeeiserner Muffen3, die in den Kesselmantel eingeschweißt :sind und in welche die Umlaufrohre 2 eingewalzt sind. Diese Anschlußstelle ist bei dem Ausführungsbeispiel durch Schamottesteine geschützt. Die Wasserumlaufrohre liegen in den Seitenzügen4 versetzt zueinander, <so daß sie sämtlich von den Rauchgasen. gut umspült werden.With the outer jacket of the boiler i, the water circulation pipes 2 are of this type Verbuhden that they are below the horizontal boiler center plane just above the lowest point of the boiler bottom and at the top above the horizontal one The boiler center level flows out below the water level. The connection is made at the bottom with the help of wrought-iron sleeves3, which are welded into the boiler shell : are and in which the circulation pipes 2 are rolled. This junction is in the embodiment protected by firebricks. The water circulation pipes are offset from one another in the sidebars4, <so that they are all separated from the Smoke gases. be washed around well.
