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.
