PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine weitere Ausbildung des Vorwärmers für Kesselspeisewasser nach Patent 268831, bei welchem die der Eintrittsstelle des Speisewassers zunächstliegenden Vorwärmerröhren unter Freilassung eines Zwischenraumes von Mänteln umgeben sind, welche die Berührung der wasserführenden Röhren mit den Heizgasen verhindern. Während hierbei die Zwischenräume zwischen den einzelnen Vorwärmerröhren und ihrem Mantel völlig abgeschlossen und mit stehender Luft oder sonst einem in Ruhe befindlichen Mittel gefüllt sind, sind gemäß vorliegender Erfindung die einzelnen Zwischenräume unter sich verbunden und gegebenenfalls mit dem Außenraum in Verbindung gebracht, so daß eine Umlaufsbewegung der Luft eintreten kann und dadurch ein besserer Wärmeaustausch zwischen Gasen und Speisewasser ermöglicht wird.The invention relates to a further embodiment of the preheater for boiler feed water according to patent 268831, in which those are closest to the entry point of the feed water Preheater tubes are surrounded by sheaths leaving a space free, which make contact with the water-bearing Prevent pipes with the heating gases. While doing this, the spaces between the individual preheater tubes and your Coat completely closed and with still air or something else at rest Means are filled, are, according to the present invention, the individual spaces connected with each other and possibly brought into connection with the outside space, so that a circulating movement of the air can occur and thereby a better heat exchange between gases and feed water is made possible.
Auf der Zeichnung ist der Gegenstand der Erfindung in einem senkrechten Schnitt durch eine Reihe der der Eintrittsstelle des Speisewassers zunächstliegenden Vorwärmerröhren dargestellt.In the drawing, the subject of the invention is in a vertical section a row of the preheater tubes closest to the entry point of the feed water shown.
Von den in bekannter Weise im Fuchs einer Dampfkesselanlage eingebauten Vorwärmerröhren α sind die der Eintrittsstelle des Speisewassers benachbarten Röhren, wie beim Gegenstand des Patents 268831, von Mänteln b Of the preheater tubes α installed in the fox of a steam boiler system in a known manner, the tubes adjacent to the entry point of the feed water, as in the subject of patent 268831, of jackets b

umgeben, die sie vor der Berührung mit den Heizgasen schützen. Gemäß vorliegender Erfindung sind die Zwischenräume c zwischen den Vorwärmerröhren α und den Mänteln b durch Rohrstutzen ä verbunden, und außerdem ist ein außerhalb liegendes Umlaufsrohr d1 vorgesehen, so daß stets dieselbe warme Luft mit Hilfe einer Pumpvorrichtung e oder vermöge ihres eigenen Auftriebes in beständigem Kreislauf durch die Zwischenräume c hindurchgetrieben werden kann. Auf diese Weise soll einerseits der Wärmeaustausch zwischen dem Speisewasser und den Heizgasen verbessert werden, während andererseits ein Feuchtigkeitsniederschlag auf den Vorwärmerröhren ausgeschlossen ist.that protect them from contact with the heating gases. According to the present invention, the spaces c between the preheater tubes α and the jackets b are connected by pipe sockets ä , and an external circulation pipe d 1 is provided so that the same warm air is always in constant circulation with the aid of a pumping device e or by virtue of its own buoyancy can be driven through the spaces c. In this way, on the one hand, the heat exchange between the feed water and the heating gases is to be improved, while, on the other hand, a condensation of moisture on the preheater tubes is excluded.
