Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen von den Kesselabgasen beheizten Speisewasservorwärmer mit so hintereinander geschalteten Rippenröhren, daß sie vom Wasser im Gegenstrom zu den Heizgasen durchflossen werden. Solche Speisewasservorwärmer sind bekannt; auch ist es nicht mehr neu, deren Röhren mit zahlreichen, quer zur Rohrlänge liegenden Heizrippen zu versehen. Das Wesen der Erfindung bestehtThe invention relates to a feed water preheater heated by the boiler exhaust gases finned tubes connected one behind the other in such a way that they flow from the water in countercurrent to the Heating gases are flowed through. Such feedwater preheaters are known; also it is no longer new, the tubes of which are closed with numerous heating fins lying across the length of the tube Mistake. The essence of the invention consists
ίο darin, daß die die Röhren umfassenden Querrippen an beiden Rohrseiten dachförmig abfallen. ίο in that the transverse ribs surrounding the tubes sloping down like a roof on both sides of the pipe.
Diese besondere Ausgestaltung der Heizrippen an den Vorwärmeröhren hat den bekannten Rippenanordnungen gegenüber den bedeutenden Vorteil, daß die aufsteigenden Heizgase nach unten gehalten werden und der Gasstrom gezwungen wird, die Röhren in ihrem ganzen Umfange zu umfalten, wodurch eine Vergrößerung der Heizfläche und somit ein erhöhter Heizwert erreicht wird. Weiterhin wird durch diese zwangläufige Führung des Gasstromes und die Schräglage der Rippen ein Anstauen der Flugasche auf den Rippen verhindert.This special design of the heating ribs on the preheater tubes has the known one Rib arrangements over the significant advantage that the rising heating gases are kept down and the gas flow is forced to fold over the entire circumference of the tubes, whereby an enlargement of the heating surface and thus an increased calorific value is achieved. Farther is due to this inevitable guidance of the gas flow and the inclined position of the ribs prevents the fly ash from building up on the ribs.
Auf der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsart dargestellt, und zwar zeigen Fig. 1 den Vorwärmer von der Seite gesehen, teilweise im Schnitt, Fig. 2 den Vorwärmer von vorn gesehen. The subject of the invention is shown in an exemplary embodiment in the drawing shown, namely Fig. 1 shows the preheater seen from the side, partially in Section, Fig. 2 seen the preheater from the front.
Die gußeisernen Röhren a, die mit den Verteilungskörpern c, wovon der obere gleichzeitig alsAbdeckplatte desZuges dient, geeignet verbunden sind, sind gemäß der Erfindung mit den dachförmig abfallenden Rippen b, welche im oberen Punkte zusammenstoßen oder auch versetzt sein können, ausgerüstet. Die mit diesen Rippen erzielte Heizgasströmung ist in Fig. ι durch Pfeile angedeutet.The cast-iron tubes a, which are suitably connected to the distribution bodies c, of which the upper one also serves as a cover plate for the train, are equipped according to the invention with the roof-shaped sloping ribs b, which meet at the upper point or can also be offset. The heating gas flow achieved with these ribs is indicated by arrows in FIG.
