Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft einen Wasserröhrenkessel mit Ober- und Unterkessel, welch letzterer aus einem liegenden, die Feuerung mit dicht aneinander liegenden Windungen umschließenden ' Schlangenrohr gebildet ist. Bei dem neuen Kessel wird bei möglichster Ausnutzung der Heizfläche den Verbrennungsgasen gestattet, senkrecht zur Achse des Unterkessels nach dem Oberkessel abzuziehen.The invention relates to a water tube boiler with an upper and lower boiler, the latter from a lying, surrounding the furnace with tightly spaced turns 'Snake tube is formed. With the new boiler, maximum utilization is possible the heating surface allows the combustion gases, perpendicular to the axis of the Subtract the lower kettle after the upper kettle.

ίο Der neue Wasserröhrenkessel ist in Fig. ι in Seitenansicht und im Längsschnitt durch den Unterkessel, in Fig. 2 in Stirnansicht dargestellt. Fig. 3 veranschaulicht den das hintere Ende des Unterkessels bildenden Rohrteil.ίο The new water tube boiler is in Fig. ι in side view and in longitudinal section through the lower boiler, in Fig. 2 in front view shown. Fig. 3 illustrates that forming the rear end of the sub-kettle Pipe part.

Der Oberkessel A des aus geschlängelten Röhren bestehenden Dampferzeugers ruht auf einem als Unterkessel dienenden Teil C, welcher aus einem Schlangenrohr zu einer walzenförmigen Gestalt gebildet ist. Das Schlangenrohr des Unterkessels ist in bekannter Weise so gewunden, daß die einzelnen Windungen sich berühren; die Neuerung besteht darin, daß die Windungen in dem Teile der Mantelfläche, welche gegen den Oberkessel A gerichtet ist, für den Durchlaß der Feuergase zum Oberkessel in Abständen nach innen durchgebogen sind. Das hintere Ende des Unterkessels ist durch den in Fig. 3 veranschaulichten Rohrteil B geschlossen, während das Stirnende mit einer den Brenner D tragenden Wand E abschließt. Die in das Innere des Unterkessels geförderten Verbrennungsgase treffen überall wasser- oder dampfgekühlte Rohrteile und können dann senkrecht zur Achse des Unterkessels nach dem Oberkessel abziehen. Die den heißesten Gasen ausgesetzten Rohrteile des Unterkessels zeigen in den Ausbiegungen nach innen eine durch Stauchung etwas vergrößerte Wandstärke, was für die Haltbarkeit des Unterkessels von Vorteil ist. Ein Wärmeverlust wird möglichst verhütet, da die Verbrennungsgase nur auf ihrem Wege zum Oberkessel A den Rohrmantel durchbrechen können.The upper boiler A of the steam generator consisting of serpentine tubes rests on a part C serving as a lower boiler, which is formed from a serpentine tube into a cylindrical shape. The serpentine tube of the lower boiler is twisted in a known manner so that the individual turns touch each other; The innovation consists in the fact that the turns in the part of the lateral surface which is directed towards the upper boiler A are bent inwards at intervals for the passage of the fire gases to the upper boiler. The rear end of the lower boiler is closed by the tube part B illustrated in FIG. 3, while the front end terminates with a wall E carrying the burner D. The combustion gases conveyed into the interior of the lower boiler meet water or steam-cooled pipe parts everywhere and can then withdraw perpendicular to the axis of the lower boiler to the upper boiler. The tube parts of the lower kettle exposed to the hottest gases show in the bends inward a somewhat increased wall thickness due to compression, which is advantageous for the durability of the lower kettle. Heat loss is prevented as much as possible, since the combustion gases can only break through the pipe jacket on their way to the upper boiler A.
