Description

Wasserrohrkessel mit je einer Ober-'und Untertrommel. Erfindungsgegenstand ist ein Wasserrohrkessel mit Ober- und Untertrommel, bei welchem die .Wasserrohre, welche die vordere Obertrommel mit der Untertrommel verbinden, in zwei getrennten Bündeln derart angeordnet sind, daß zwischen denselben ein befahrbarer Raum vorhanden ist, in welchem der überhitzer Platz finden kann.Water tube boiler with one upper and one lower drum each. Subject matter of the invention is a water tube boiler with upper and lower drum, in which the .water tubes, which connect the front upper drum with the lower drum, in two separate ones Bundles are arranged in such a way that there is a passable space between them is where the superheater can find its place.

Wasserrohrkessel der bezeichneten Art sind an sich bekannt. Der Erfindungsgegenstand unterscheidet sich jedoch grundsätzlich von den älteren Erfindungen dadurch, daß bei ihm der Raum zwischen .den beiden Rohrbündeln in 'kwei !übereinan.derliegende Kammern unterteilt ist, von denen lediglich die obere, zur Aufnahme des Überhitzers bestimmte, von den Rauchgasen durchströmt wird, während die untere einen ringsum durch feuerfestes Mauerwerk umschlossenen Hohlraum bildet, der gegebenenfalls mit der Atmosphäre in Verbindung gebracht werden kann, ohne das hierdurch eine Beeinträchtigung,der Rauchgasbewegung eintritt.Water tube boilers of the type indicated are known per se. The subject of the invention However, it differs fundamentally from the older inventions in that in his case, the space between the two tube bundles in kwei one above the other Chambers is divided, of which only the upper one, to accommodate the superheater certain, is traversed by the flue gases, while the lower one is all around Forms cavity enclosed by fireproof masonry, possibly with the atmosphere can be connected without impairing the Flue gas movement occurs.

Durch diese Anordnung werden folgende Vorteile gegenüber den bekannten Ausführungsformen erzielt: z. Vermeidung von Zugverlusten durch scharfe Richtungsänderungen und Wirbelungen der Rauchgase, wie sie an den scharfen Kanten der @ üblichen einfachen dünnen Zuglenkplatten unvermeidlich sind.This arrangement has the following advantages over the known Embodiments achieved: e.g. Avoidance of tensile losses due to sharp changes in direction and eddies of the flue gases, such as those on the sharp edges of the @ usual simple thin pulling plates are inevitable.

2. Leichte Beobachtungsmöglichkeit und Instandhaltung der Zuglenkwände durch Befahren des unteren von Mauerwerk eingeschlossenen Hohlraumes; Ausbesserungsarbeiten können notfalls während des Betriebes vorgenommen werden, wobei die Staubfreiheit des Arbeitsraumes als besonderer Vorteil in Betracht kommt.2. Easy observation and maintenance of the train steering walls by driving through the lower cavity enclosed by masonry; Repair work can, if necessary, be carried out during operation, whereby the dust-free of the work area comes into consideration as a particular advantage.

3. Längere Betriebsperioden des Kessels werden ermöglicht, da die Ausbildung der Zugkanäle ein Ausfallen der Flugasche innerhalb des Kessels verhindert.3. Longer operating periods of the boiler are made possible because the Formation of the draft channels prevents the fly ash from falling out within the boiler.

Die Decke der unteren Kammer bildet ein geeignetes Tragorgan für den Überhitzer, dessen liegende Anordnung bei anderen Äusführungsformen auf Schwierigkeiten stößt, da es .an der erforderlichen Unterstützung fehlt. Die Abb. i läßt eine Ausführungsform des Erfindungsgegenstandes erkennen. Der Kesselkörper besteht aus der Untertrommel i, dem Steigrohrbündel a, ,der Obertrommel und dem Fallrohrbündel q.. Der Zwiischenraum zwischen den entsprechend geformten Rohrbündeln ist derart unterteilt, daß zwei übereinander liegende Kammern 5 und 6 gebildet werden, von denen lediglich die obere, in welcher gegebenenfalls der Überhitzer untergebracht werden kann, von den Rauchgasen durchströmt wird, während die untere einen ringsum von feuerfestem Mauerwerk oder sonstigem geeigneten Material umschlossenen Hohlraum bildet.The ceiling of the lower chamber forms a suitable support for the Superheater, the horizontal arrangement of which has difficulties with other forms of execution because it lacks the necessary support. Fig. i reveals an embodiment of the subject matter of the invention. The boiler body consists of the lower drum i, the riser tube bundle a, the upper drum and the Downpipe bundle q .. The space between the appropriately shaped pipe bundles is subdivided in such a way that two superimposed chambers 5 and 6 are formed, of which only the upper one, in which the superheater is housed if necessary can be flowed through by the flue gases, while the lower one all around cavity enclosed by fireproof masonry or other suitable material forms.
