Description

Die Erfindung bezieht sich auf einen Wasserrohrkessel, insbesondere Wasserrohrschiffskessel mit natürlichem Umlauf, aus einer Obertrommel und mehreren: Untertrommeln, von denen zwei höher gelegen und durch je ein Rohrbündel derart mit der Obertrommel verbunden sind, daß zwischen den Trommeln und den Rohrbündeln ein Überhitzer eingeschoben werden kann, nach Patent gig 588. Zur Sicherung eines geordneten Wasserumlaufes von der höher liegenden Untertrommel zu der tiefer gelegenen[ sind beim Kessel des Hauptpatentes jeweils an den Enden der Trommeln Fallrohre größeren Durchmessers angeordnet. Beim Zuströmen des Kesselwassers von der Obertrommel durch das Fallrohrbündel zu der höher gelegenen Untertrommel und von dort durch die an den Enden der Trommeln vorgesehenen Fallrohre größeren Durchmessers zu der tiefer gelegenen Untertrommel besteht nun die Gefahr, daß sich in beiden Untertrommeln Querströme ausbilden, die den geordneten Kreislauf des Wassers durch den Kessel gefährden. Die Ausbildung derartiger Querströme soll durch die Erfindung vermieden werden, und zwar ohne daß der Ein- und Ausbau der Überhitzerschlangen erschwert wird.The invention relates to a water tube boiler, in particular Water tube ship boiler with natural circulation, consisting of an upper drum and several: Lower drums, two of which are higher up and each with a tube bundle in such a way the upper drum are connected that between the drums and the tube bundle one Superheater can be inserted, according to patent gig 588. To ensure an orderly Water circulation from the higher lying lower drum to the lower lying one in the case of the boiler of the main patent, downpipes are larger at the ends of the drums Arranged diameter. When the boiler water flows through from the upper drum the downpipe bundle to the higher lower drum and from there through the the larger diameter downpipes provided at the ends of the drums to the deeper ones located lower drum is now the risk that both lower drums Form cross-currents, which the orderly circulation of the water through the boiler endanger. The invention is intended to avoid the formation of such cross-currents without making the installation and removal of the superheater coils difficult will.

Gemäß der Erfindung wird die höher liegende Untertrommel mit der tiefer liegenden durch gleichmäßig über die ganze Länge der Trommeln verteilte Fallrohre kleineren Durchmessers verbunden, wobei es zweckmäßig ist, diese zusätzlichen Fallrohre, um das Einschieben des Überhitzers von der Kessellängsseite aus einwandfrei zu ermöglichen, so auf die Trommellänge zu verteilen, daß zwischen den einzelnen Fallrohren jeweils genügend Raum zum Einschieben der einzelnen. Überhitzerschlangen verbleibt.According to the invention, the lower drum located higher with the lower lying through downpipes evenly distributed over the entire length of the drums smaller diameter connected, whereby it is advisable to use these additional downpipes, to enable the superheater to be pushed in properly from the longitudinal side of the boiler, to be distributed over the length of the drum so that between the individual downpipes enough space to slide each. Superheater coils remains.

Die Zeichnung zeigt ein Ausführungsbeispiel, und zwar in Fig. i einen vergrößerten Teilausschnitt aus dem Ausführungsbeispiel in Fig. i des Hauptpatents, in Fig. 2 einen Schnitt durch die Fig. i auf der Schnittlinie A-B und in Fig. 3 einen Schnitt durch die Fig. i auf der Linie C-D.The drawing shows an embodiment, namely in Fig. I a enlarged partial section from the embodiment in Fig. i of the main patent, in FIG. 2 a section through FIG. i on the section line A-B and in FIG. 3 a section through Fig. i on the line C-D.

Die höher liegende. Trommel 2 der beiden Untertrommeln 2, 3 ist mit der nicht dargestellten Obertrommel durch das nur an den Einwalzstellen gezeichnete Fallrohrbündel4 verbunden. Die tiefer liegende Trommel 3 des unterenTrommelpaares 2, 3 ist durch das schräge Rohrbündel 5, nur an den Einwalzstellen angedeutet, ebenfalls mit der Obertrommel i verbunden. Die beiden Trommeln ?- und 3 stehen nun ihrerseits durch die beiden starken Fallrohre 16 jeweils an den Trommelenden miteinander in Verbindung. Um den Querstrom in den Trommeln :2 und 3, der etwa in Richtung der eingezeichneten Pfeile fließen würde, zu vermeiden, sind über die ganze Länge der beiden Trommeln 2 -und 3 gleichmäßig verteilt zusätzlich die Fallrohre 18 kleineren Durchmessers angeordnet, durch die ein gleichmäßiger Zustrom von der Trommel :2 zur Trommel 3 gewährleistet ist. Aus der Trommel 3 fließt das Wasser weiter zur tiefstgelegenen Untertrommel durch die Fallrohre 17 ab. Um die Überhitzerschlangen i i bequem und einwandfrei von der Kessellängsseite her ein- und ausbauen zu können, sind dabei die zusätzlichen Fallrohre 18 so aufgeteilt, daß zwischen ihnen genügend Raum für das Einschieben verbleibt. Zur Stützung der Schräglage der überhitzerschlangen sind außerdem die wasserführenden Tragrohre ig vorgesehen.The higher one. Drum 2 of the two lower drums 2, 3 is connected to the upper drum (not shown) by the downpipe bundle 4 shown only at the rolling-in points. The lower drum 3 of the lower drum pair 2, 3 is also connected to the upper drum i by the inclined tube bundle 5, only indicated at the rolling-in points. The two drums ? - and 3 are in turn connected to one another through the two strong downpipes 16 at the drum ends. In order to avoid the cross-flow in drums: 2 and 3, which would flow roughly in the direction of the arrows drawn, the downpipes 18 of smaller diameter are also distributed evenly over the entire length of the two drums 2 and 3, through which a more even Inflow from the drum: 2 to drum 3 is guaranteed. From the drum 3, the water flows on to the lowest-lying lower drum through the downpipes 17. In order to be able to install and remove the superheater coils ii conveniently and properly from the longitudinal side of the boiler, the additional downpipes 18 are divided so that there is enough space between them for insertion. The water-carrying support pipes ig are also provided to support the inclined position of the superheater coils.
