Abstract

Abhitzekessel mit Rippenrohren, bei dem vorgesehen ist, dass die Mittelachsen der in einer ersten waagerechten Reihe angeordneten Rippenrohre mit der Mittelachse der in einer zweiten waagerechten Reihe angeordneten Rohre zusammenfällt, d.h. in Reihe angeordnet sind, und dass im trichterförmigen, im oberen Teil zwischen zwei benachbarten Rohren vorgesehenen Bereich für den Gasaustritt ein V-förmig ausgebildetes Leitblech vorgesehen ist, das sich über die gesamte Länge der Rohre erstreckt, und dass die freien Enden des Leitbleches dem unteren Umfang der obenliegenden Rippenrohre zugekehrt sind.

Figure 00000001
Waste heat boiler with finned tubes, in which it is provided that the central axes of the finned tubes arranged in a first horizontal row coincide with the central axis of the tubes arranged in a second horizontal row, that is to say are arranged in a row, and that in the funnel-shaped part, in the upper part, between two adjacent ones Pipe provided area for the gas outlet, a V-shaped baffle is provided, which extends over the entire length of the tubes, and that the free ends of the baffle face the lower periphery of the overhead finned tubes.
