Description

Steilrohrkessel mit gleichgerichtet liegender Ober- und Untertrommel und dazwischen angeordneten Tragrohren Bei Steilrohrkesseln mit gleichgerichtet liegender Ober- und Untertrommel ist es bekannt, beide Kesseltrommeln durch wenige Reihen gerade oder fast gerade Rohre zu verbinden, die Tragrohre genannt «-erden, während die Hauptmenge der dampferzeugenden Rohre mehr od; r weniger stark gekrümmt ist.Steep tube boiler with upper and lower drum lying in the same direction and supporting tubes arranged in between. With vertical tube boilers with rectified lying upper and lower drum it is known, both boiler drums by a few To connect rows of straight or almost straight pipes, called the support pipes, while the majority of the steam-generating tubes od more; r less strongly curved is.

Man hat diese Tragrohre bisher über @lie ganze Breite des Rohrbündels gleichmäßig verteilt angeordnet, um eine möglichst kräftige Verbindung der beiden Kesseltrommeln zu erzielen. Das hat aber den Nachteil, daß beim Krummziehen der Untertrommel infolge ungleichmäßiger Erwärmung die Tragrohre auch durch diese Trommelbiegung beansprucht werden und sich in ihren Einwalzstellen lockern müssen.So far, these supporting tubes have been used over the entire width of the tube bundle Evenly spaced to ensure the strongest possible connection between the two To achieve boiler drums. However, this has the disadvantage that when the Lower drum as a result of uneven heating, the support tubes also due to this drum bending are stressed and have to loosen in their rolled-in points.

Um diesen Übelstand zu vermeiden, werden Mach der Erfindung die Tragrohre in zwei Gruppen angeordnet, die symmetrisch zur Kesselmitte so angeordnet sind, daß bei Durchbiegung einer oder beider Trommeln die Abstandsunterschiede der Trommeln auf ein Mindestmaß beschränkt werden. Die zwischen diesen beiden Gruppen von Tragrohren befindliche Lücke wird dabei durch Rohre ausgefüllt, die in der Längsachse der Trommeln gebogen sind, wobei die Biegungen abwechselnd und versetzt zueinander oben und unten liegen, so daß durchgehende Lücken in diesen Rohrreihen vermieden werden.In order to avoid this drawback, the support tubes are made of the invention arranged in two groups, which are arranged symmetrically to the center of the boiler in such a way that that when one or both drums deflect, the differences in distance between the drums be kept to a minimum. The one between these two groups of support tubes The gap is filled by tubes in the longitudinal axis of the drums are bent, the bends alternating and offset from one another above and below so that continuous gaps in these rows of pipes are avoided.

In der Zeichnung .ist als Beispiel ein Steilrohrkessel mit gleichgerichtet liegender Ober-und Untertrommel und verbindenden Röhrenbündeln in einfachen Linien dargestellt. Abb. i zeigt eine Ansicht auf den Mittelteil des Kessels von vorn gesehen unter Weglassung der Verdampferrohre; Abb. :2 zeigt einen senkrechten Schnitt durch den Kessel bei den Ankerrohren, Abb. 3 dasselbe bei den zwischen den Ankerrohren liegenden Füllrohren.In the drawing, a steep tube boiler is rectified as an example lying upper and lower drum and connecting tube bundles in simple lines shown. Fig. I shows a view of the middle part of the boiler seen from the front omitting the evaporator tubes; Fig.: 2 shows a vertical section through the boiler for the anchor tubes, Fig. 3 the same for the one between the anchor tubes lying filling pipes.

Der Kessel besteht aus der Obertrommel a und der Untertrommel b, die durch :die Rohrbündel c und d in bekannter Weise miteinander verbunden sind. Zwischen diesen beiden Rohrbündeln befinden sich Ankerrohre c, die Ober- und Untertrommel miteinander verbinden und, wie die Abb. :2 zeigt, möglichst gerade und unelastisch ausgeführt sind. Diese Ankerrohre e werden in Bündeln zusammengefaßt und in .einem solchen Abstand von der Mitte des Kessels nach beiden Seiten zu gleichmäßig angeordnet (Abb. i), daß alle durch Verbiegungen hervorgerufenen Abstandsänderungen der Trommeln auf ein Mindestmaß herabgedrückt werden. Die Ankerrohre e werden ihrem Zweck entsprechend besonders kräftig ausgebildet; sie können auch einen größeren Durchmesser als die Verdampf errohre erhalten und zum Schutz gegen die Feuergase mit Steinen umkleidet werden. Zwischen diesen beiden Bündeln von Ankerrohren kann man dann noch Verd.ampfungsrohre h, anordnen, die in beliebiger Weise gekrümmt sein müssen, damit sie den Formänderungen der Trommeln und ihrer eigenen Ausdehnung folgen können, ohne ihre Einwalzstelle übermäßig zu beanspruchen.The boiler consists of the upper drum a and the lower drum b, the by: the tube bundles c and d are connected to one another in a known manner. Between These two tube bundles contain anchor tubes c, the upper and lower drum connect with each other and, as Fig. 2 shows, as straight and inelastic as possible are executed. These anchor tubes e are combined in bundles and in .einem such a distance from the center of the boiler on both sides to be arranged evenly (Fig. I) that all changes in the distance of the drums caused by bending be pushed down to a minimum. The anchor tubes e are according to their purpose particularly strong; they can also have a larger diameter than that Evaporation tubes received and clad with stones to protect against the gases of the fire will. Evaporation tubes can then be placed between these two bundles of anchor tubes h, arrange that must be curved in any way so that they can Shape changes can follow the drums and their own expansion without their roll-in point overuse.

In Abb. i ist dargestellt, wie diese Rohre geformt sein können, um eine dünne Rohrwand zu erzielen. Alle Rohre sind genau gleich ausgeführt; sie werden gruppenweise zusammengefaßt und zwei solcher Gruppen umgekehrt symmetrisch angeordnet, während die so gebildeten Gruppenpaare unter sich ebenfalls wieder umgekehrt symmetrisch neben- und hintereinanderliegen. Dadurch wind erreicht, daß man mit einer einzigen Rohrform auskommt und daß die durch_ _die Kreuzung der Rohre bedingten Lücken i verdeckt sind, so daß die Gase nicht nach einer bestimmten Seite des Kessels gezogen ,#verden.In Fig. I it is shown how these tubes can be shaped to to achieve a thin pipe wall. All pipes are made exactly the same; you will be grouped together and two such groups arranged reversely symmetrically, while the group pairs formed in this way are also reversely symmetrical among themselves lying next to and behind each other. This makes it possible to wind up with a single Pipe shape and that the gaps caused by the crossing of the pipes i are covered so that the gases are not drawn to a certain side of the boiler , # verden.
