Description

Steilrohrkessel, @ der aus zwei dachförmig gegeneinander geneigten, oben und unten mit Wasserkammer ausgerüsteten Rohrbündeln besteht. Bei den bekannten Steilr ohrkesseln, die aus zwei dachförmig gegeneinander geneigten, oben und unten mit Wasserkammern ausgerüsteten Rohrbündeln bestehen, macht es gewisse Schwierigkeiten, einen. guten Abschluß des Feuergewölbes nach oben zu bilden, da die zwischen den oberen beiderseitigen Wasserkammern einzubauenden Abschlußsteine keinen rechten Halt finden. Die vorliegende Erfindung gibt ein Mittel zur Abhilfe dieser Schwierigkeit an, welches durch eine besondere Bauart der Kesses dargeboten wird. Erfindungsgemäß werden die innersten Rohrreihen jedes Bündels oben kurz unterhalb der Wasserkammern abgekröpft und zu den Wasserkammern des gegenüberliegenden Bündels geführt, so daß sich also die inneren Rohrreihen in der Nähe der oberen Wasserkammern kreuzen. Auf der so entstandenen Kreuzungsstelle, di;e an und für sich schon einen Abschluß des Feuerraumes nach oben bildet, können dann die Abschlußsteine ohne Schwierigkeit aufgelegt werden und finden hier eine gute Unterstützung, so daß ein Herausfallen derselben auch bei den Bewegungen und Erschütterungen der Kesselteile durch den Betrieb nicht befürchtet zu werden braucht.Steep tube boiler, @ which consists of two roof-shaped inclined towards each other, consists of tube bundles equipped with a water chamber at the top and bottom. With the known Above and below, steep tubular kettles consisting of two roof-shaped sloping towards each other tube bundles equipped with water chambers, it creates certain difficulties a. to form a good end of the fire vault upwards, since the between the upper bilateral water chambers to be built in end stones no right Find a hold. The present invention provides a means of overcoming this difficulty which is presented by a special design of the Kesses. According to the invention are the innermost rows of tubes of each bundle at the top just below the water chambers bent and led to the water chambers of the opposite bundle, so that So the inner rows of tubes cross near the upper water chambers. on the intersection point created in this way, di; e in and of itself already a conclusion of the The firebox forms upwards, the end stones can then be used without difficulty and find good support here, so that they fall out same also with the movements and vibrations of the boiler parts by the Operation need not be feared.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die beiden. Rohrbündel a und b, die jeweils oben und unten mit Wasserkammern c und d bzw. e und f versehen sind, haben die bekannte dachförmige Lage zueinander; die Feuerung kann sich in der Mitte zwischen den beiden Rohrbündeln oder auch auf einer Seite befinden. Die vordere Rohrreihe g und h eines jeden Bündels ist in der Nähe der oberen Wasserkammer abgebogen und anstatt in die eigene obere Rohrkammer in diejenige des gegenüberliegenden Bündels geführt, so daß sich die Rohre kreuzen. Auf der Kreu7un.gsstelle sind die Steinei für den oberen Abschluß des Feuerraumes aufgelegt, dien wie aus der Zeichnung ohne weiteres zu -erkennen ist, hier eine besonders gute Unterstützung finden.An exemplary embodiment of the invention is shown in the drawing. The two. Tube bundles a and b, which are each provided with water chambers c and d or e and f at the top and bottom, have the known roof-shaped position to one another; the furnace can be located in the middle between the two tube bundles or on one side. The front row of tubes g and h of each bundle is bent near the upper water chamber and, instead of being led into its own upper tube chamber, into that of the opposite bundle, so that the tubes intersect. The stones for the upper end of the combustion chamber are placed on the crossing point, which, as can be easily recognized from the drawing, are particularly well supported here.
