Description

Steilrohrkessel mit Untertrommel und tiberhitzer verbindender Rohrleitung. In allen Steilrohrkesseln entsteht naturgemäß im Unterkessel eine untere kalte Wasserschicht, die gefährliche Spannungen im Mantel des Unterkessels verursachen kann. Man versucht vielfach, das kalte Wasser aus dem unteren Teil des Unterkessels durch beson-dere Lenkbleche, Flügelräder, zu entfernen oder durch Heizschlangen oder direkte Einführung von Dampf zu erwärmen.Vertical tube boiler with lower drum and pipeline connecting the superheater. In all steep tube boilers, a lower layer of cold water naturally arises in the lower boiler, which can cause dangerous stresses in the jacket of the lower boiler. Attempts are often made to remove the cold water from the lower part of the lower boiler using special guide plates, impellers, or to heat it using heating coils or direct introduction of steam.

EL-Z.facher ist der Ausweg, den Unterkessel an den überhitzer anzuschließen, so daß das Wasser aus dem Unterkessel zum Füller. des überhitzers dient. Demgegenüber besteht das Wesen dier Erfindung darin, das Wasser nur dem unteren Teil des Unterkessels zu entnehmen, da hierdurch auf einfache Weise eine gleichmäßige Erwärmung des Unterkessels bewirkt und in diesem die untere kältere Wasserschicht gezwungen ist, nach oben in den Überhitzer zu strömen. Beim Anheizen vrird Wasser im überhitzer verdampft, kaltes Wasser aus dem Unterkessel fließt nach, so daß hierdurch bald eine gleichmäßige Erwärmung des Unterkessels eintritt.EL-Z.facher is the way out to connect the lower boiler to the superheater, so that the water from the lower boiler to the filler. of the superheater is used. In contrast The essence of the invention consists in the water only in the lower part of the lower boiler can be seen, as this results in an even heating of the lower boiler in a simple manner causes and in this the lower colder water layer is forced to the top to flow into the superheater. When heating up, water in the superheater evaporates, cold water from the lower boiler flows in, so that this soon becomes even Heating of the lower boiler occurs.

Eine Ausfülnungsform der Erfindung ist in der Zeichnung veranschaulicht.One embodiment of the invention is illustrated in the drawing.

a ist zier Oberkessel, b der Unterkessel; c sind die diese Kessel verbindenden -Steilrohre; d ist der überhitzer, ,der sein Wasser aus der untersten Stelle des Unterkessels ansaugt und in den Oberkessel abführt. a is the decorative upper kettle, b the lower kettle; c are the sub-pipes connecting these boilers; d is the superheater, which sucks in its water from the lowest point of the lower boiler and discharges it into the upper boiler.

Claims (1)

PATENT-13N SPRUCH: Steilrohrkessei mit Untertrommel und Überhitzer verbindender Rohrleitung, dadurch gekennzeichnet, daß die Rohrleitung derart in den unteren Teil der Untertrommel einmündet, daß beim Anheizen das Kesselwasser aus dem unteren Teil der Untertrommel in den Ürberhitzer gesaugt wird. PATENT-13N Slogan: Steep tube boiler with pipeline connecting lower drum and superheater, characterized in that the pipeline opens into the lower part of the lower drum in such a way that the boiler water is sucked from the lower part of the lower drum into the superheater when it is heated up.
