Description

Anordnung für Dampfsammler an Dampfkesseln mit künstlich erhöhtem Umlauf des Wassers. Es ist bekannt, das Wasser in einem Dampfkessel künstlich, z. B. durch eine Pumpe, in schnellem Umlauf zu halten, um die entstehenden Dampfblasen schnell von den Wandungen zu entfernen, so daß stets neue Wasserteilchen mit diesen in Berührung kommen und verdampfen.Arrangement for steam collectors on steam boilers with artificially increased Circulation of water. It is known to artificially water the water in a steam boiler, e.g. B. by a pump to keep in rapid circulation to avoid the resulting vapor bubbles quickly removed from the walls, so that there are always new water particles with them come in contact and evaporate.

Vorliegende Erfindung stellt eine weitere Ausbildung dieses Gedankens dar und besteht darin, daß bei solchen Dampfkesseln mit künstlich erhöhtem Umlauf des Wassers nur ein Teil des kreisenden Dampf-Wassergemisches durch den Dampfsammler des Kessels hindurchgeleitet wird, während der übrige Teil in den Strömungsweg im Kessel zurückfließt, ohne den Dampfsammler durchströmt zu haben. Hierdurch kann die Wassergeschwindigkeit im Dampfsammler klein, im Kessel dagegen groß gehalten werden. Sowohl Dampfsammler wie Kessel werden dann also mit der jeweils günstigsten Geschwindigkeit durchströmt, da die kleine Geschwindigkeit im Dampfsammler dort die Abscheidung des Dampfes begünstigt, während die große Geschwindigkeit im Kessel aus den eingangs erwähnten Gründen vorteilhaft ist.The present invention provides a further development of this idea and consists in the fact that in such steam boilers with artificially increased circulation of the water only part of the circulating steam-water mixture through the steam collector of the boiler is passed through, while the remaining part in the flow path in the The boiler flows back without having flowed through the steam collector. This can the water speed in the steam collector is low, but kept high in the boiler will. Both steam collectors and boilers are then offered with the cheapest Speed flows through because the small speed in the steam collector there the separation of the steam favors, while the high speed in the boiler is advantageous for the reasons mentioned at the beginning.

In der Zeichnung ist schematisch eine beispielsweise Ausführungsform der Erfindung an einem Hochdruckkessel dargestellt. Es ist a der aus in einer Ebene ausgebreiteten Rohren bestehende Oberkessel, welcher zugleich Dampfsammler ist, b der Unterkessel, c eine Kreiselpumpe zur künstlichenAufrechterhaltung eines Kreislaufes des Wassers und d ein dem Oberkessel parallel liegendes Umgehungsrohr. Der Durchströmungsquerschnitt des letzteren ist durch ein in der Zeichnung links neben dem Pfeil sichtbares Drosselorgan einstellbar. Die Wirkung des mehr oder weniger eingeschalteten Umgehungsrohres besteht in einer entsprechenden Herabsetzung der Wassergeschwindigkeit in den Rohren des Oberkessels a, der demzufolge kleiner gehalten werden kann, und einer guten Abscheidung der Dampfblasen.In the drawing is a schematic example of an embodiment the invention shown on a high pressure boiler. It's a the one out in a plane upper boiler, which is also a steam collector, b the lower boiler, c a centrifugal pump for the artificial maintenance of a cycle of the water and d a bypass pipe lying parallel to the upper boiler. The flow cross-section the latter is through a throttle organ visible to the left of the arrow in the drawing adjustable. The effect of the more or less switched on bypass pipe exists in a corresponding reduction in the water velocity in the pipes of the Upper boiler a, which can therefore be kept smaller, and a good separation the steam bubbles.

PATENT-ANSPRUCH: Anordnung für Dampfsammler an Dampfkesseln mit künstlich erhöhtere Umlauf des Wassers, dadurch gekennzeichnet, daß nur ein Teil des kreisenden Dampf - Wassergemisches durch den Dampfsammler hindurchgeleitet wird, während der übrige Teil z. B. durch ein Umgehungsrohr (d) in den Strömungsweg im Kessel zurückfließt, ohne den Dampfsammler durchströmt zu haben, um die Wassergeschwindigkeit im Dampfsammler klein, im Kessel dagegen groß zu machen. PATENT CLAIM: Arrangement for steam collector on steam boilers with artificially increased circulation of the water, characterized in that only part of the circulating steam - water mixture is passed through the steam collector, while the remaining part z. B. flows back through a bypass pipe (d) into the flow path in the boiler without having flowed through the steam collector to make the water velocity in the steam collector small, but large in the boiler.
