Description

Vorwärmer mit biegsamen, gewellten Heizröhren. Die Erfindung betrifft einen Vorwärmer, dessen Heizfläche durch biegsame, gewellte Metallrohre gebildet ist, und .besteht darin, daß die Rohre mittels eines kegelförmigen Kopfes in dem Vorwärmergehäuse abgedichtet sind. Diese Ausgestaltung bietet den Vorteil, daß die bei Vorwärinern ähnlicher Art sonst zur Anwendung kommenden Stopfbüchsen für die Abdichtung- nicht erforderlich sind.Preheater with flexible, corrugated heating tubes. The invention relates to a preheater, the heating surface of which is formed by flexible, corrugated metal tubes is, and. consists in that the tubes by means of a conical head in the Preheater housing are sealed. This configuration offers the advantage that the in the case of preheaters of a similar type, stuffing boxes otherwise used for the Sealing- are not required.

Auf der Zeichnung ist ein Ausführungsbeispiel des neuen Vorwärmers im Längsschnitt dargestellt.In the drawing is an embodiment of the new preheater shown in longitudinal section.

Das vorzuwärmende Wasser tritt durch die Öffnung z des Gehäuses r ein und verläßt es durch die Öffnung 3, nachdem es die Weltrohre q., durch die der Dampf strömt, umspült hat. Die Rohre 4 münden an beiden Enden in Kammern 7, die mittels eines kegelförmigen Kopfes 8 in den Endplatten des Gehäuses r abgedichtet sind. Die Stützen 5 und 6, die zum Ein- und Austritt des Dampfes dienen, sind mit Gewinde versehen und enthalten Muttern 9, durch welche die Köpfe 8 fest gegen die Abdichtungsflächen in den Endplatten des Gehäuses gedrückt werden.The water to be preheated passes through the opening z of the housing r a and leaves it through the opening 3, after it the world tubes q., through which the Steam flows around it. The tubes 4 open at both ends in chambers 7, the sealed by means of a conical head 8 in the end plates of the housing r are. The supports 5 and 6, which are used for entry and exit of the steam, are with Provided thread and contain nuts 9, through which the heads 8 firmly against the Sealing surfaces are pressed into the end plates of the housing.

Die neue Gestaltung ergibt nur eine ebenso einfache wie zuverlässige Abdichtung.The new design only results in one that is as simple as it is reliable Seal.
