    Speisewasservorwärmer.   



     Speisewasservorwärmer,   die von den Kesselabgasen beheizt werden und bei denen die Rippenrohre so   hintereinandergeschaltot   werden, dass sie vom Wasser im Gegenstrom zu den Heizgasen durchflossen werden, sind bekannt. Auch ist es nicht mehr   nen,   deren Rohre mit zahlreichen, quer zur Rohrlänge liegenden Heizrippen zu versehen. 



   Das Wesen der Erfindung besteht nun darin, die vertikalen Rohre derartiger Speisewasservorwärmer mit umfassenden Querrippen zu versehen, die an beiden Rohrseiten dachförmig abfallen. Die Rohre sind hiebei so angeordnet, dass sich die Rippen benachbarter Rohre nicht berühren. 



   Diese besondere Ausgestaltung der Heizrippen an den Vorwärmerrohren hat den bekannten Rippenanordnungen gegenüber den bedeutenden Vorteil, dass die aufsteigenden Heizgase nach unten gehalten werden und der Gasstrom gezwungen wird, die Rohre in ihrem ganzen Umfange zu umfluten, wodurch eine Vergrösserung der Heizfläche und somit ein erhöhter   Heizoffekt   erzielt wird. 



   Weiterhin wird durch diese zwangläufige   Führung   des Gasstromes und die Schräglage der Rippen jegliches Anstauen der Flugasche auf den Rippen verhindert. 



   In der Zeichnung ist der Ertindungsgegenstand in einer beispielsweisen Aus-   führl1ngsart   dargestellt, und zwar zeigt :
Fig. 1 den   Vorwärmer   von der Seite gesehen. teilweise im Schnitt. 



   Fig. 2 den Vorwärmer von vorn gesehen,
Fig. 3 die Vorrichtung im Grundriss,
Fig. 4 die   zwangläufige   Führung der Rauchgas. 



   Die gusseisernen Rohre   M   werden mit Rippen b, welche im oberen Punkte zusammenstossen oder auch versetzt sein können, ausgerüstet und mit den   Verteilungskörpern c,   wovon der obere gleichzeitig als Abdeckplatte des Zuges dient, geeignet verbunden. 



   Die mit den-dachförmigen Rippen nach Art des Erfindungsgegenstandes erzielte   Heizgasströmung   ist in Fig. 4 durch Pfeile angedeutet.

    Feed water preheater.



     Feedwater preheaters that are heated by the boiler exhaust gases and in which the finned tubes are connected in series so that the water flows through them in countercurrent to the heating gases are known. It is also no longer necessary to provide the pipes with numerous heating fins lying across the length of the pipe.



   The essence of the invention consists in providing the vertical pipes of such feedwater preheaters with comprehensive transverse ribs which slope down like a roof on both pipe sides. The tubes are arranged so that the ribs of adjacent tubes do not touch.



   This special design of the heating fins on the preheater pipes has the significant advantage over the known fin arrangements that the rising heating gases are kept down and the gas flow is forced to flood the pipes in their entire circumference, which increases the heating surface and thus an increased heating effect is achieved.



   Furthermore, this compulsory guidance of the gas flow and the inclined position of the ribs prevent any accumulation of fly ash on the ribs.



   In the drawing, the subject of the invention is shown in an exemplary embodiment, namely:
Fig. 1 seen the preheater from the side. partly in cut.



   2 the preheater seen from the front,
3 shows the device in plan,
4 shows the inevitable guidance of the flue gas.



   The cast iron pipes M are equipped with ribs b, which meet at the upper point or can also be offset, and are suitably connected to the distribution bodies c, of which the upper one also serves as a cover plate for the train.



   The heating gas flow achieved with the roof-shaped ribs in the manner of the subject matter of the invention is indicated in FIG. 4 by arrows.
