Description

2. Entgaser nach Anspruch I, dadurch gekennzeichnet, daß das Heizdampfdrosselglled des einen Mischvorwärmers (c1, c2) mit dem des folgenden Mischvorwärmers (c2, Q) beispielsweise durch eine Leitung (s1, s2) so verbunden ist, daß die Heizdampfmenge des vorhergehenden Mischvorwärmers (c1, c2) gedrosselt wird, sobald das Heizzudampfventil (i2, i3) des folgenden Mischvorwärmers (c2, c3) geöffnet wird. 2. Degasser according to claim I, characterized in that the Heizdampfdrosselglled of one mixer preheater (c1, c2) with that of the following mixer preheater (c2, Q) for example by a line (s1, s2) is connected so that the heating steam of the previous mixing preheater (c1, c2) is throttled as soon as the heating steam valve (i2, i3) of the following mixer preheater (c2, c3) is opened.

Entgaser Zusatz zum Patent 707 706 Die Entgasungsanlage nach Patent 707 706 benutzt Heizdampfventile, die sich nur ganz öffnen oder schließen und daher keine feinere Regelung der Heizdampfmenge zulassen. Infolgedessen besteht die Möglichkeit, daß der zugehörige Mischvorwärmer eine zu hohe Temperatur erhält, wenn eine Abnahme seiner Kondensatmenge nach Schließen des Überströmventils in der Überströmleitung nach dem folgenden Mischvorwärmer eintritt. Degassing add-on to patent 707 706 The degassing system according to patent 707 706 uses heating steam valves that only open or close completely and therefore do not allow any finer regulation of the amount of heating steam. As a result, there is the possibility that the associated mixer preheater receives too high a temperature when there is a decrease its amount of condensate after closing the overflow valve in the overflow line occurs after the following mixer preheater. Dies wird durch die Zusatzerfindung vermieden. Gemäß dieser wird jledem Heizdampfventil ein Drosselglied vorgeschaltet, dessen Kolben von dem Druckunterschied zwischen dem Mischvorwärmer und dem gemeinsamen Niederdruckraum betätigt wird. This is avoided by the additional invention. According to this will Each heating steam valve is preceded by a throttle element, the piston of which depends on the pressure difference is operated between the mixer preheater and the common low-pressure space. Nach Anstellen des Heizdampfventils der folgenden Abteilung erhält der Kolblen durch eine Verbindungsleitung mit der betreffenden Heizleitung Schließdruck, so daß der Heizdampf der vorhergehenden Abteilung der verbleibenden Kondensatmenge entsprechend gedrosselt wird.After switching on the heating steam valve the following department receives closing pressure of the piston through a connecting line with the relevant heating line, so that the heating steam of the previous compartment of the remaining amount of condensate is throttled accordingly. Die Zeichnung zeigt ein Ausführungsbeispiel. The drawing shows an embodiment. Dler Heizdampf strömt durch die Zweigleitungen nl, n2, n3, in denen die Drosselglieder rt, r2, r3 den Heizdampfventilen il, i2, is vorgeschaltet sind, in die Mischvorwärmer ct, c2, cs, von denen das vorgewärmte Wasser in die Entgaserrohrbündel f1, f2, f3 abfließt. Die Kolben t1, t2, t3 der Drosselglieder werden auf der einen Seite durch den durch die Rohre ul, u2, u3 zugeführten Druck im Niederdruckraum R, auf der anderen Seite durch den durch die Rohre v1, v2, v3 zugeführten Druck im Mischvorwärmer und gegebenenfalls durch den Druck des Heizdampfes des folgenden Mischvorwärmers, der durch eine Verbindungsleitung sl, s2 über tragen wird, gesteuert. The heating steam flows through the branch lines nl, n2, n3, in which the throttling elements rt, r2, r3 are connected upstream of the heating steam valves il, i2, is, into the mixer preheaters ct, c2, cs, from which the preheated water enters the degasser tube bundle f1, f2, f3 flows off. The pistons t1, t2, t3 of the throttle elements are on the one hand Side by the pressure supplied through the tubes ul, u2, u3 in the low-pressure space R, on the other hand, by the pressure supplied through pipes v1, v2, v3 in the mixing preheater and possibly by the pressure of the heating steam of the following Mixing preheater, which is carried through a connecting line sl, s2, controlled. Hierdurch ist der Vorteil gegeben, daß der Druckunterschied zwischen den Räumen über und unter dem Entgaserrohrbündel und damit auch die Entgasungstemperatur nahezu entsprechend der in eine Abteilung einströmenden Kondensatmenge geregelt wird. This has the advantage that the pressure difference between the spaces above and below the degassing tube bundle and thus also the degassing temperature regulated almost in accordance with the amount of condensate flowing into a department will. P A T E N T A N S P R Ü C H E: 1. Entgaser nach Patent 707 706, dadurch gekennzeichnet, daß vor jedem Heizdampfventil (i1, i2, i3) ein Heizdampfdrosselglied (r1, r2, r3) vorgesehen ist, das durch die Veränderung des Druckunterschiedes in den Räumen über und unter dem Entgaserrohrbündel (f1, f2, f3) den Druck innerhalb des Mischvorwärmers (c1, C2, c3) regelt. P A T E N T A N S P R Ü C H E: 1. Degasser according to patent 707 706, thereby characterized in that in front of each heating steam valve (i1, i2, i3) a heating steam throttle element (r1, r2, r3) is provided, which by changing the pressure difference in the spaces above and below the degasser tube bundle (f1, f2, f3) the pressure inside of the mixer preheater (c1, C2, c3).
