Description

Die Erfindung betrifft Dampfkessel mit einem Oberkessel, bei welchen )Rohrbündel, welche die Vorder-und Rückwand des Kessels besetzen, in Nebensammelrohre münden. Derartige Dampfkessel sind an sich bekannt.The invention relates to steam boilers with an upper boiler in which ) Tube bundles, which occupy the front and rear walls of the boiler, in secondary manifolds flow out. Such steam boilers are known per se.

Gegenstand der Erfindung ist eine Verbesserung von Dampfkesseln dieser Art, die darin besteht, daß an der Stelle, an der die Nebensammelrohre in den Oberkessel münden, vor den Mündungen Schalen angeordnet werden, die oben längs einer zu der normalen Wasserfläche des Kessels parallelen Ebene offen sind, und zwar etwas oberhalb derselben. Eine in dem eingetauchten Teil der Schale vorgesehene kleine Öffnung bewirkt den statischen Ausgleich zwischen dem Wasser in der Schale und dem Wasser des Kessels.The invention relates to an improvement in steam boilers Kind, which consists in the fact that at the point where the secondary collecting pipes in the upper boiler open, in front of the mouths shells are arranged, the top along one of the normal water surface of the boiler parallel plane are open, something above the same. A small opening provided in the submerged part of the bowl causes the static balance between the water in the bowl and the water of the boiler.

Diese Anordnung ergibt insbesondere folgende Vorteile: a) sie ermöglicht das beständige Entweichen des in dem Nebensammelraum erzeugten Dampf-Wasser-Gemisches; b) sie verhindert das Fortschleudern dieses Dampf-Wasser-Gemisches in die Dampfentnahmevorrichtung; c) sie ermöglicht es, die Speisung der oberen Nebensammelrohre mit unmittelbar aus dem Oberkessel kommendem Wasser zu kontrollieren und so die Kondensierungs- und Wasserschlagerscheinungen zu verhindern, die in diesen auftreten können.This arrangement results in the following advantages in particular: a) it enables the constant escape of the steam-water mixture generated in the secondary plenum; b) it prevents this steam-water mixture from being thrown out into the steam extraction device; c) it enables the supply of the upper secondary manifolds with directly from to control the water coming to the upper boiler and thus the condensation and To prevent water hammer phenomena that can occur in these.

Es ist hiernach klar, daß die Erfindung nichts mit bekannten Anordnungen von Dampfkesseln zu tun hat, bei welchen eine große Anzahl von Rohren unmittelbar in den Sammelraum des Oberkessels münden, statt in ein Nebensammelrohr. Bei solchen Anordnungen ist die Menge des durch jedes der zahlreichen Einzelrohre zugeführten Dampf-Wasser-Gemisches viel zu gering, um überhaupt eine Regelung notwendig zu machen. Die bei den bekannten Anordnungen mitunter vor den Einmündungen der Rohre in den Kesselraum vorgesehenen Abschirmungen haben mit einer Regelung nichts zu tun, sondern dienen lediglich als Leitorgane.It will hereafter be clear that the invention has nothing to do with known arrangements has to do with steam boilers in which a large number of pipes directly open into the collecting chamber of the upper boiler instead of into a secondary collecting pipe. In such Arrangements is the amount supplied by each of the numerous individual tubes The steam-water mixture is far too small to even require regulation. In the known arrangements sometimes in front of the junctions of the tubes in the The shields provided in the boiler room have nothing to do with a regulation, but rather serve only as guiding bodies.

In den Abbildungen ist ein Ausführungsbeispiel der den Gegenstand der Erfindung bildenden Vorrichtung dargestellt.In the figures, an embodiment of the is the subject the invention forming device shown.

Abb. i ist ein Längsschnitt des Oberkessels an der Mündungsstelle eines Nebensammelrohres; Abb. 2 ist ein Schnitt längs der Linie 2-2 der Abb. i. Auf dieser Zeichnung stellt a den Oberkessel dar, in welchen das Nebensammelrohs b mündet, c sind die in dieses einmündenden Verdampfungsrohre, d ist das Wasserrückflußrohr und e das Dampfsammelrohr. Die neue Vorrichtung besteht im wesentlichen aus einer Schale f, welche die Mündung des Nebensammelrohres b so abdeckt, daß sie das aus diesem austretende Dampf-Wasser-Gemisch zu der Oberfläche der Wasserfläche leitet. Die Schale f hat eine einzige Öffnung, welche an ihrer Oberseite in einer zu der normalen Wasserfläche des Kessels parallelen Ebene und etwas oberhalb dieser liegt. Ein an dem unteren Teil der Schale angebrachtes Loch f 1 von geringem Durchmesser bewirkt das statische Gleichgewicht des Systems.Fig. I is a longitudinal section of the upper boiler at the mouth a secondary manifold; Figure 2 is a section along line 2-2 of Figure i. In this drawing, a represents the upper boiler in which the secondary collecting pipes b opens out, c are the evaporation tubes opening into this, d is the water reflux tube and e the steam manifold. The new device consists essentially of one Shell f, which covers the mouth of the secondary manifold b so that it is out this escaping steam-water mixture leads to the surface of the water surface. The shell f has a single opening which at its top in one to the normal water surface of the boiler parallel plane and slightly above this. A small diameter hole f 1 made in the lower part of the shell causes the static equilibrium of the system.

Die Vorrichtung wird durch Schirme aus Streckmetall g vervollständigt, deren Aufgabe es ist, das unmittelbare Mitreißen des Dampf-Wasser-Gemisches durch die Dampfentnahmeleitung oder die Rohre, welche wie in dem dargestellten Beispiel das Dampfsammelrohr e speisen, zu verhindern.The device is completed by screens made of expanded metal g, whose task it is to ensure that the steam-water mixture is immediately carried away the steam extraction line or the pipes, which as in the example shown feed the steam manifold e to prevent.
