Description
Die Erfindung betrifft einen Dampferzeuger mit viereckigem Feuerraumquerschnitt und Strahlungsheizflächen an den Wänden des Feuerraumes.The invention relates to a steam generator with a square furnace cross-section and radiant heating surfaces on the walls of the furnace.
Die Strahlungsheizflächen gehen hierbei im allgemeinen von unteren Verteilern aus. Bei bekannten Kesseln, bei welchen den Verteilern an deren Kreuzungsstelle über ein Fallrohr Wasser zugeführt wird, entstehen hier Knotenpunkte durch den Zusammenschluß von drei Rohren, die schweißtechnisch nur sehr schwer herzustellen sind, sollen sie den gestellten Anforderungen gewachsen sein. Außerdem muß bei Anordnung von Verteilern auf gleicher Höhe darauf geachtet werden, daß jeder Verteiler zur Beseitigung von Schlamm zugänglich ist.The radiant heating surfaces generally come from below Distributors. In known boilers in which the distributors at their intersection If water is supplied via a downpipe, nodes are created here as a result of the merger of three pipes, which are very difficult to manufacture in terms of welding technology they can meet the requirements. In addition, if Distributors at the same height make sure that every distributor is removed accessible from mud.
Der Erfindung liegt die Aufgabe zugrunde, einen Dampferzeuger zu schaffen, bei welchem schwierige Knotenpunktverschweißungen wegfallen und bei welchem darüber hinaus der in den unteren Verteilern anfallende Schlamm so abgeführt wird, daß bestenfalls zwei Verteiler mit Reinigungsverschlüssen versehen werden müssen.The invention is based on the object of creating a steam generator, at which difficult node welds are omitted and at which above In addition, the sludge in the lower distributors is removed in such a way that at best two distributors must be provided with cleaning closures.
Zur Lösung der gestellten Aufgabe wird für einen Dampferzeuger der eingangs genannten Gattung vorgeschlagen, daß die Strahlungsrohre von einem aus Rohren zusammengeschweißten Verteilungssystem ausgehen, das in den Ecken. durch Fallrohre mit Umlaufwasser versorgt wird, wobei die Verteiler in der Höhe versetzt an den Fallrohren so angeschweißt sind, daß die Verteiler zweier gegenüberliegender Wände höher liegen als die Verteiler der anderen beiden Wände.To solve the problem, the is for a steam generator suggested that the radiation tubes from one Pipes welded together distribution system go out in the corners. by Downpipes are supplied with circulating water, with the manifold offset in height are welded to the downpipes so that the manifolds of two opposite Walls are higher than the manifolds of the other two walls.
Man erreicht durch diese Anordnung, daß eine Anhäufung von Rohren in einem Knotenpunkt vermieden und die Verschweißung der Rohre erleichtert wird. Durch das Höherlegen von zwei Verteilern erreicht man weiter, daß, hervorgerufen durch die von oben nach unten gerichtete Strömung in den Fallrohren, der Schlamm sich in den tiefer liegenden Verteilern ansammelt. Somit sind nur zwei Verteiler zugänglich zu machen, wofür vorteilhafterweise die beiden Seitenwandverteiler vorgesehen werden, da meist vor den Kesseln mehr Platz vorhanden ist als an den Seiten, so daß der Gebrauch von Reinigungsgeräten nicht behindert wird. Außerdem gelingt es so, mehrere Kessel dicht nebeneinander aufzustellen. Die Fallrohre können über die unteren Verteiler hinaus verlängert sein, wobei diese Verlängerung dann noch als Schlammsack dienen kann.It is achieved by this arrangement that an accumulation of pipes avoided in a node and the welding of the pipes is facilitated. By raising two distributors you can achieve that, caused due to the flow in the downpipes from top to bottom, the sludge collects in the lower-lying distributors. So there are only two distributors to make accessible, for which purpose the two side wall distributors are advantageously provided as there is usually more space in front of the boilers than on the sides, see above that the use of cleaning equipment is not hindered. It also works so, to set up several kettles close to each other. The downpipes can over the lower manifold also be extended, this extension then still as Mud bag can serve.
Die Erfindung ist an einem Beispiel an Hand der Zeichnung erläutert.The invention is explained using an example with reference to the drawing.
Fig. i zeigt einen lotrechten Längsschnitt und Fig.2 einen waagerechten Schnitt durch den Dampferzeuger.Fig. I shows a vertical longitudinal section and Fig. 2 a horizontal Section through the steam generator.
Die Fallrohre i sind mit den unteren Verteilern 2 und 3, von welchen die den viereckigen Feuerraum einschließenden Strahlungsrohre ausgehen, verbunden. Gemäß der Erfindung sind im Beispiel die Verteiler 2 für die einander gegenüberliegenden Seitenwände tiefer angeordnet als die Verteiler für die wiederum einander gegenüberliegende Vorder- und Rückwand. Die Fallrohre i sind über die unteren Verteiler 2 hinaus verlängert, so daß sich hier Schlamm ansammeln kann, der von Zeit zu Zeit abgeführt wird.The downpipes i are with the lower manifolds 2 and 3, of which the radiant tubes that enclose the square furnace are connected. According to the invention, in the example, the manifolds 2 are for the opposite one another Side walls arranged lower than the manifold for the again opposite one another Front and back wall. The downpipes i are extended beyond the lower distributor 2, so that mud can collect here, which is removed from time to time.
