Description

Verfahren zur Aufrechterhaltung einer möglichst gleichbleibenden Ablauftemperatur dampfbeheizter Wasservorwärmer. Die Erfindung betrifft ein Verfahren zur Aufrechterhaltung einer möglichst gleichbleibenden Ablauftemperatur von dampfbeheizten Wasservorwärmern bei veränderlichem Wasserzulauf. Dies wird gemäß der Erfindung dadurch erreicht, daß die Größe der Heizfläche und der vom Wasser bespülten Oberfläche des Vorwärmers je nach der zufließenden Wassermenge verändert wird.Procedure for maintaining an outlet temperature that is as constant as possible steam-heated water preheater. The invention relates to a method of maintenance the most constant outlet temperature possible from steam-heated water preheaters with variable water supply. According to the invention, this is achieved by that the size of the heating surface and the surface of the preheater flushed by the water is changed depending on the amount of water flowing in.

Der Erfindungsgegenstand ist in der Zeichnung in Abb. r bis q. in beispielsweiser Ausführung veranschaulicht.The subject of the invention is shown in the drawing in Figs. R to q. in exemplified execution illustrated.

Zwecks Veränderung der Größe der Heizfläche bzw. der vom Wasser bespülten Fläche ist der Vorwärmer in mehrere abschaltbare Kammern a, b, c unterteilt, welche in bezug auf ihren Dampf- oder Wasserzufluß parallel oder hintereinander geschaltet werden können. Bei der in Abb. t dargestellten Ausführungsform arbeiten diese Vorwärmerteile in bezug auf die Dampfzuführung in Parallelbetrieb und in bezug auf die Wasserzuführung in Hintereinanderschaltung, während gemäß Abb. a dieselben von Dampf und Wasser nacheinander durchflossen werden.To change the size of the heating surface or the area flushed with water area the preheater is divided into several disconnectable chambers a, b, c divided, which with respect to their steam or water flow parallel or one behind the other can be switched. Work in the embodiment shown in Fig. T these preheater parts with respect to the steam supply in parallel operation and with respect to on the water supply in series, while according to Fig. a the same steam and water flow through one after the other.

Abb.3 zeigt eine Anordnung, bei welcher der Dampf- und Wasserzufluß zu den Vorwärmerkammern a, b, c in Parallelschaltung erfolgt. In Abb. q. sind die Vorwärmerkammern hinsichtlich Dampfzufuhr hintereinander, hinsichtlich Wasserzufluß j edoch parallel geschaltet. Die Gleichhaltung der Ablauftemperatur wird, wie bereits erwähnt, durch Zu- und Abschalten einzelner oder mehrerer Vorwärmerteile ermöglicht. Zu diesem Zwecke sind in deren Dampf- bzw. Wasserzuflußleitungen ' geeignete Absperrorgane vorgesehen.Fig. 3 shows an arrangement in which the steam and water flow to the preheater chambers a, b, c are connected in parallel. In Fig.q. If the preheater chambers are connected one behind the other with regard to steam supply, but in parallel with regard to water supply. As already mentioned, keeping the outlet temperature constant is made possible by connecting and disconnecting individual or multiple preheater parts. For this purpose, suitable shut-off devices are provided in their steam or water supply lines.

Das den Gegenstand der Erfindung bildende Verfahren kann zur Erwärmung von Wasser irgendwelcher Herkunft, z. B. Kondensat, oder zur Vorwärmung von anderen Flüssigkeiten verwendet werden. Als Betriebsmittel für den Vorwärmer kann Abdampf oder auch höher gespannter Dampf benutzt werden.The method forming the subject of the invention can be for heating of water of any origin, e.g. B. condensate, or to preheat others Liquids are used. Exhaust steam can be used as the operating medium for the preheater or higher-tension steam can be used.
