Description
Die Erfindung betrifft einen Wasserröhrenkessel mit Ober- und Unterkessel verbindenden Verdampfungsröhren und in Röhrenbündel aufgelösten Fallröhren. Die Erfindung bezweckt, bei derartigen bekannten Schiffswasserröhrenkesseln für hohe Beanspruchung den Wasserumlauf so zu beschleunigen, daß die Verdampfungsröhren immer genügend gekühlt werden, ohne zu unbequemen Abmessungen imThe invention relates to a water tube boiler with connecting upper and lower boiler Evaporation tubes and downpipes dissolved in bundles of tubes. The invention aims in such known ship water tube boilers for high stress the water circulation to accelerate so that the evaporation tubes are always sufficiently cooled, without uncomfortable dimensions in the
ίο Gesamtfallrohrquerschnitt zu gelangen. Die Erfindung besteht darin, daß zur Verstärkung der Wirkung der Fallröhren eine künstliche äußere Abkühlung derselben dadurch herbeigeführt wird, daß die gesamte Verbrennungsluft durch die abgeschlossenen Fallröhrenbündel hindurchgeführt wird.ίο to reach the total downpipe cross-section. the Invention consists in the fact that an artificial one to increase the effect of the downspouts external cooling of the same is brought about by the fact that all of the combustion air is passed through the closed bundle of downspouts.
Auf der Zeichnung ist ein Schiffswasserröhrenkessel mit der Neuerung in Fig. 1 und 2 im senkrechten und wagerechten Querschnitt in einfachen Linien dargestellt.On the drawing is a ship's water tube boiler with the innovation in FIGS. 1 and 2 shown in vertical and horizontal cross-section in simple lines.
Die dargestellte Gestaltung des Wasserröhrenkessels mit dem Oberkessel a, den Unterkesseln b, den Luftdüsen c einer ölfeuerung, den Verdampfungsröhrenbündeln d und den Fallröhrenbündeln e ist bekannt. Die Neuerung besteht darin, daß die gesamte Verbrennungsluft in Richtung der eingezeichneten Pfeile durch die abgeschlossenen Fallröhrenbündel e hindurchgeführt wird. Durch diese Art der Luftzuführung werden die Fallröhren und das in ihnen enthaltene Wasser wirksam gekühlt, dadurch der Unterschied zwischen dem spezifischen Gewicht des Fallröhreninhaltes und dem des Verdampfungsröhreninhaltes vergrößert und somit der Wasserumlauf beschleunigt. Zugleich wird die sonst nutzlose und lästige Wärmeausstrahlung der Fallröhren zur Vorwärmung der Verbrennungsluft ausgenutzt. The illustrated design of the water tube boiler with the upper boiler a, the lower boilers b, the air nozzles c of an oil furnace, the evaporation tube bundles d and the downcomer bundles e is known. The innovation is that all of the combustion air is passed in the direction of the arrows drawn through the closed down tube bundle e . This type of air supply effectively cools the downpipes and the water they contain, thereby increasing the difference between the specific gravity of the downpipe contents and that of the evaporation pipe contents and thus accelerating the water circulation. At the same time, the otherwise useless and annoying heat radiation from the downpipes is used to preheat the combustion air.
