Description

Steilrohrkessel mit quer zum Flammenweg angeordnetem Unterkessel und senkrecht zu letzterem stehendem Oberkessel. Die Erfindung bezieht sich auf Stailrohrkessel mit quer zum Flammenweg angeordnetem Unterkessel und senkrecht zu letzterem stehendem Oberkessel und diese verbindenden Steilrohrbündel.Steep tube boiler with a lower boiler arranged at right angles to the flame path and perpendicular to the latter upper boiler. The invention relates to steel tube boilers with a lower boiler arranged transversely to the flame path and perpendicular to the latter Upper boiler and this connecting vertical tube bundle.

Das Wesen der Erfindung besteht in der Anordnung von Rohrgassen quer zur Richtung des Flammenweges, durch welche die Rohre ausgewechselt werden können., ohne die Bildung von Flammenwegen zu begünstigen.The essence of the invention consists in the arrangement of pipe lanes transversely the direction of the flame path through which the tubes can be replaced., without promoting the formation of flame paths.

Gasseen. zur Auswechselung der Rohre waren bei Steilrohrkesseln an sich bekannt. Sie betrafen aber Kessel anderer Systeme, z. B. Gaxbe-System, wobei aber der Zweck, Flammengassen zu verhüten, weder angestrebt noch erreicht war. Bei. Anwendung der an sich bekannten Anordnung von Rohrgassen. bei Kesseln des eingangs beschriebenen Systems ergeben sich ganz besondere Vorteile, die schon dadurch bedingt sind, daß die Steilrohre, welche Unterkessel und Oberkessel verbinden, die ganze Front zur Feuerung ein-nehmen, so daß die Verhütung won Flammengassen, hierbei. ganz besonders wichtig ist.Alleys. to replace the tubes were known per se in steep tube boilers. But they concerned boilers of other systems, e.g. B. Gaxbe system, but the purpose of preventing flames, was neither sought nor achieved. At. Use of the known arrangement of pipe lanes. with boilers of the initially described system results in some of the other advantages which are already due to the fact that the ball pipes, which sub-boiler and steam drum connect the entire front for firing a -take, so that the prevention won flame lanes, here. is particularly important.

Das Durchschlagen. ,der Flamme durch solche Rohrlücken würde eine nicht genügende Ausnutzung der Rohrbündel bewirken und wäre insbesondere bei Verfeuerung von langflammigen Kohlen von Nachteil. Bei unserer Anordnung ist die Möglichkeit einer Gassenbildung für die Flamme vollständig ausgeschlossen, die Rohrbündel bilden eine . geschlossene Wand, die sich der Heizwirkung der Flamme direkt darbietet und die Flamme zwingt, durch schmale Gaskanäle zu ziehen, wodurch die denkbar beste Ausnutzung der Wärme erzielt wird. In den zur Flammenrichtung querliegenden Rohrgassen können sich die Gase darin wieder ausdehnen, um dann durch die weiter dahinterliegenden Rohrwände abzuziehen.The breakthrough. , the flame through such gaps in the pipe would cause a cause insufficient utilization of the tube bundle and would be particularly in the case of combustion long-flame coals are a disadvantage. With our arrangement there is the possibility gas formation for the flame is completely excluded, the tube bundles form one . closed wall that is directly exposed to the heating effect of the flame and forces the flame to pull through narrow gas channels, making the best imaginable Utilization of the heat is achieved. In the pipe lanes that are transverse to the direction of the flame the gases in it can expand again, and then through the ones further behind Pull off pipe walls.

Ein Ausführungsbeispiel der Erfindung ist in der beigefügten Zeichnung in Abb. i in Seätenriß und in Abb. a in einer Draufsicht auf die Unterkessel dargestellt. Die Rohrbündel sind mit a bezeichnet, die dazwischen angeordneten Rohrgassen, die also quer zum Flammenweg liegen, mit b; c sind die Zwischenräume (Gaskanäle) zwischen den Röhren.An embodiment of the invention is shown in the accompanying drawing in Fig. i in a plan view and in Fig. a in a plan view of the lower boiler. The tube bundles are denoted by a, the tube lanes arranged in between, the so lie across the flame path, with b; c are the spaces (gas channels) between the tubes.
