Description

Steilrohrkessel. Bei Steilrohrkesseln, bei denen der Feuerraum sich vor dem ersten Steilrohrbündel in seiner ganzen Höhe erstreckt, ist es notwendig, die dem Feuerraum zugewandten Rohre nicht in ihrer ganzen Länge der starken Bestrahlung und Beheizung durch die Gase auszusetzen. Man hat bereits, um die Belastung dieser Rohre auf ein erträgliches Maß herabzudrücken, den oberen Teil derselben der Beheizung entzogen. Das hat aber bei engen Rohren, wie sie für Hochdruckkessel benutzt werden müssen, den Nachteil, daß der abzuführende Dampf sich auf dem langen Weg zum Kessel anstaut, so daß die Sicherheit der Rohre gefährdet ist= .Nach der Erfindung wird nur im oberen Teil dieser Rohre Dampf erzeugt, während der untere Teil sowohl der Bestrahlung vom Feuerraum aus als auch der Belieizung durch Berührung mit den Feuergasen entzogen wird, indem er nach dem Feuerraum zu durch eine feuerfeste Wand und nach dem Heizgaszug zu durch die übliche Lenkwand abgeschlossen wird. Dadurch wird dem in diesen Rohren erzeugten Dampf der kürzeste Weg zum Oberkessel bereitet, und es wird dafür Sorge getragen, daß das Wasser, welches dieser hochbeanspruchten Heizfläche zufließt, nicht schon teilweise in Dampf verwandelt ist.Steep tube boiler. With steep tube boilers, where the combustion chamber is extends in its entire height in front of the first vertical tube bundle, it is necessary to the pipes facing the furnace are not exposed to the strong irradiation over their entire length and suspend heating by the gases. One already has to take to the strain of this To press down pipes to a tolerable level, the upper part of the same of heating withdrawn. But this has to do with narrow pipes such as those used for high-pressure boilers must have the disadvantage that the payable Steam yourself on the long Way to the boiler backs up, so that the safety of the pipes is endangered = .After the Invention, steam is generated only in the upper part of these pipes, while the lower Part of the irradiation from the furnace as well as the exposure by touch with the fire gases is withdrawn by going to the firebox through a refractory Wall and after the heating gas flue is closed by the usual steering wall. Through this the shortest route to the upper boiler is prepared for the steam generated in these pipes, and care is taken that the water, which these highly stressed The heating surface flows in and has not already been partially converted into steam.

In der Zeichnung ist ein Steilrohrkessel dieser Art im senkrechten Querschnitt dargestellt. Der Kessel besteht aus zwei Steilrohrelementen, die im Zuge der Heizgase hintereinanderliegen. Das erste Steilrohrbündel a ist so angeordnet, daB die Heizgase von der hier als Treppenrost gezeigten Feuerung b im oberen Teil des Rohrbündels eintreten, während die erste Rohrreihe d durch eine Abdeckung c, d in ihrem unteren Teil der Einwirkung der Strahlung und der Heizgase vollständig entzogen ist. Der Feuerraum e ist in seiner ganzen Breite bis zur Höhe des Rohrelementes durchgeführt. Die Gase werden nach Durchstreichen des Rohrbündels a um die Lenkwand g herum in das Rohrbündel f geführt und verlassen dasselbe durch den Fuchs h. Man kann den obersten Teil der vorderen Rohre ä noch durch eine Lenkwand i nach dem Feuerraum zu abdecken.In the drawing, a vertical tube boiler of this type is shown in vertical cross section. The boiler consists of two vertical tube elements that lie one behind the other in the course of the heating gases. The first vertical tube bundle a is arranged in such a way that the heating gases from the furnace b, shown here as a step grate, enter the upper part of the tube bundle, while the first tube row d is completely withdrawn from the radiation and the heating gases by a cover c, d in its lower part is. The entire width of the combustion chamber e is carried out up to the height of the tubular element. After crossing the tube bundle a around the steering wall g, the gases are guided into the tube bundle f and leave the same through the fox h. The uppermost part of the front tubes can be covered by a steering wall after the combustion chamber.

Die Abdeckung d der unteren Rohre wird vorteilhaft als Feuerraummauer ausgebildet, einmal um die Rohre möglichst vor Einwirkung der Hitze zu schützen und zum andern, um durch intensive Str ahlwirkung die Verbrennung im Feuerraum zu verbessern.The cover d of the lower tubes is advantageously used as a fire room wall trained once to protect the pipes as much as possible from the effects of heat and on the other hand, to ensure combustion in the combustion chamber by means of an intensive jet effect to enhance.

PATENT-ANspRUcFI: Steilrohrkessel mit vor den Steilrohren liegendem Feuerraum und Eintritt der Heizgase in den oberen Teil des ersten Steilrohrbündels, dadurch gekennzeichnet, daB der untere Teil der vorderen Rohre dieses Steilrohrbündels dem Zuge der Heizgase vollständig entzogen ist. PATENT CLAIM: Vertical tube boiler with a combustion chamber in front of the vertical tubes and entry of the heating gases into the upper part of the first vertical tube bundle, characterized in that the lower part of the front tubes of this vertical tube bundle is completely withdrawn from the flow of the heating gases.
