Description

Die Erfingung betrifft einen stehenden Dampfkessel mit oben durch den Kessel laufendem Rauehabzugrohr.The invention concerns a standing steam boiler with above through the boiler running rough exhaust pipe.

Bei diesen stehenden Dampfkesseln besteht der Nachteil, daß, die Rauchrohre an der Wasserlinie des Kessels Korrosionserscheinungen zeigen. Es ist versucht worden, diese Anfressungen des Rauchrohres durch seitliche Rauchrohraustritte mit Hilfe von Gelenkrohren o. dgl. zu vermeiden. Auch ist- es bekannt, die nach oben gehenden Rauchrohre innen durch eine Schutzbekleidung abzudecken. Diese Schutzabdeckung zeigt nun eine starke Verzunderung durch die Rauchgase, insbesondere wegen der starken Erhitzung bei fehlender Wärmeableitung. Die bekannten Maßnahmen sind unbefriedigend. Die Erfindung erstrebt, die bestehenden Nachteile zu beseitigen.In these standing steam boilers, there is the disadvantage that the smoke tubes show signs of corrosion on the waterline of the boiler. It has been tried this corrugation of the smoke pipe through lateral smoke pipe outlets with the help of articulated pipes or the like. Avoid. Also it is known to go upwards Cover the flue pipes inside with protective clothing. This protective cover shows now a strong scaling by the flue gases, especially because of the strong Heating in the absence of heat dissipation. The known measures are unsatisfactory. The invention seeks to eliminate the existing disadvantages.

Dieser Zweck wird gemäß der Erfindung dadurch erreicht, daß das Raurhabzugrohr unter der Wasserlinie des Kessels beginnend nach oben über den Dampfraum des Kessels verlaufend einen Ringraum bildet, der unten mit dem Dampfraum des Kessels und oben mit der Dampfableitung verbunden ist. Hierdurch wird der wesentliche Vorteil erreicht, daß der den Ringraum von unten nach oben durchströmende Sattdampf eine zu schädlichen Korrosionen führende Überhitzung der von den Rauchgasen berührten Wandung des Rauchrohres verhütet. Gleichzeitig ergibt sich der Vorteil, daß der Sattdampf beim Durchströmen des Ringraumes durch die Wärmeaufnahme getrocknet wird.This purpose is achieved according to the invention in that the Raurhabzugrohr starting below the waterline of the boiler and upwards over the steam space of the boiler running forms an annular space, which below with the steam space of the boiler and above is connected to the vapor discharge. This achieves the main advantage that the saturated steam flowing through the annular space from bottom to top is too damaging Overheating of the wall of the flue pipe in contact with the flue gases, causing corrosion prevent. At the same time there is the advantage that the saturated steam flows through the annulus is dried by the heat absorption.

Gemäß der Erfindung erhält der Ringraum des Rauchabzugrohres auf seiner Länge verteilt horizontal liegende, ungefähr einen Halbkreis umfassende Ringbleche als Leitwände für den durchströmenden Sattdampf. Es wird so über die ganze Rohrlänge ein gleichmäßiger Wärmeaustausch gesichert.According to the invention, the annular space of the smoke exhaust pipe receives on his Length distributed horizontally, approximately a semicircle encircling ring plates as guide walls for the saturated steam flowing through. It will be like this over the entire length of the pipe an even heat exchange ensured.

In der Zeichnung ist die Erfindung an einem stehenden Dampfkessel veranschaulicht, von dem der obere Teil dargestellt ist. Das den oberen Kesselraum durchsetzende Rauchabzugröhr a bildet mit dem innen eingefügten, an seinen nach außen erweiterten Enden verbundenen Rohrstück b einen Ringraum c. Dieser Ringraum c ist unten durch das über dem Wasserspiegel im Kessel mündende Rohr d mit dem Dampfraum verbunden. Oben ist der Ringraum c mit dem Dampfabgangsstutzen e verbunden.In the drawing, the invention is on a standing steam boiler illustrated, the upper part of which is shown. That the upper boiler room penetrating Rauchabzugröhr a forms with the inserted inside, to his externally expanded ends connected pipe section b an annulus c. This annulus c is at the bottom through the pipe d with the steam space opening above the water level in the boiler tied together. At the top, the annular space c is connected to the steam outlet nozzle e.

In dem Ringraum c sind in entsprechenden Abständen horizontal liegende Ringbleche f festgelegt, die je etwa einen Halbkreis umfassen. Die Ringbleche sind wechselweise gegeneinander versetzt. Dem Dampf wird so ein in der Längsrichtung abgesetzter Kreisweg durch den Ringraum c vorgeschrieben und dadurch eine weitgehend gleichmäßige Wärmeverteilung erreicht. Das innere Rauchrohr d ist durch den es umspülenden Sattdampf reichlich gekühlt, so daß Verzunderungen nicht auftreten können. Bei Sattdampfentnahme wird dem Kessel ein gut vorgetrockneter Dampf entnommen.In the annular space c are located horizontally at corresponding intervals Annular sheets f set, each encompassing approximately a semicircle. The ring plates are alternately offset from one another. The steam becomes so one in the longitudinal direction offset circular path prescribed through the annulus c and thus a largely even heat distribution achieved. The inner smoke pipe d is through the wash around it Saturated steam is abundantly cooled so that scaling cannot occur. With saturated steam extraction a well-pre-dried steam is taken from the boiler.

Soll ein Überhitzer eingebaut werden, so wird die überhitzerschlange g oben an den Ringraum c angeschlossen, wie dies strichpunktiert in der Zeichnung angedeutet ist.If a superheater is to be installed, the superheater coil is used g connected to the top of the annulus c, as shown in dash-dotted lines in the drawing is indicated.
