Description

Umwälzvorrichtung.für Dampferzeuger Durch das Patent 557 251 ist eine Umwälzvorrichtung für Dampferzeuger bekannt geworden, die mittels einer Dampfstrahlpumpe bei Dampferzeugern einen verstärkten Wasserumlauf erzeugt. Bei dieser Vorrichtung fördert die Strahlpumpe Kesselwasser niederen Druckes auf einen höheren Druck durch ein Heizrohrbündel. In dem Heizrohrbündel entsteht ein Dampfwassergemisch, von dem ein Teil in, einen Abscheidet geleitet wird. Der Dampf wird dort vom Wasser getrennt und zum Betrieb der Strahlpumpe verwendet, während das abgeschiedene Wasser in einem Behälter niederen Druckes entspannt wird. In denselben Behälter niederen Druckes strömt durch eine Drosselstelle der andere Teil des vom Heizrohrbündel kommenden Dampfwassergemisches.Circulating device for steam generators. Patent 557,251 is a Circulation device for steam generators become known, which by means of a steam jet pump Generates an increased water circulation in steam generators. With this device the jet pump conveys low pressure boiler water to a higher pressure a heating tube bundle. A steam-water mixture is created in the heating tube bundle, from which a part is directed into a separator. There the steam is separated from the water and used to operate the jet pump while the separated water is in one Container is relieved of low pressure. In the same container of low pressure the other part of the heating tube bundle flows through a throttle point Steam water mixture.

Nach der vorliegenden Erfindung wird nun vorgeschlagen, daß der Sammler des Heizrohrbündels lediglich mit dem Dampfabscheider in Verbindung steht, derart, daß das gesamte, vom Heizrohrbündel kommende Dampfwassergemisch in einen besonderen Abscheidet strömt, daß der abgeschiedene Dampf zum Betrieb' der Strahlpumpe dient und daß das abgeschiedene Wasser in einen Behälter niederen Druckes fließt, in dem durch die Entspannung des hocherhitzten Wassers Dampf entsteht, der als Gebrauchsdampf einer Verwendungsstelle zugeführt werden kann. Hierdurch wird die Wirkungsweise der Strahlpumpe wesentlich verbessert. Die Erfindung sei- durch ein Beispiel an der Abbildung erläutert. Von dem Wasserabscheider k strömt hochgespannter Dampf durch die Leitungh in die Strahlpumped und fördert Wasser niederen Druckes auf einen höheren Druck durch das Rohrbündel a zum Sammler/. Das entstandene Dampfwassergemisch strömt durch die Leitung g in den Abscheidet k. Es trennt sich hier Dampf und Wasser, der Dampf strömt zur Strahlpumpe, und das Wasser wird durch ein Schwimmerventil o. ä. in dem Behälter b niederen Druckes entspannt. In dem Behälter b verdampft ein Teil des entspannten Wassers; der Dampf wird vom Wasser geschieden und durch die Leitung c zur Verwendungsstelle geleitet.According to the present invention it is now proposed that the collector of the heating tube bundle is only in connection with the steam separator, in such a way that that the entire steam water mixture coming from the heating tube bundle in a special one Separates flows that the separated vapor is used to operate 'the jet pump and that the separated water flows into a low pressure container in which The expansion of the highly heated water creates steam, which is used as utility steam can be supplied to a point of use. This is how it works the jet pump significantly improved. Let the invention be given by way of an example explained in the figure. High pressure steam flows from the water separator k pumped through the conduit into the jet and conveys water of low pressure to one higher pressure through the tube bundle a to the collector /. The resulting steam-water mixture flows through line g into separator k. Steam and water separate here, the steam flows to the jet pump, and the water is through a float valve or the like. Relaxed in the container b low pressure. Evaporated in the container b part of the relaxed water; the steam is separated from the water and through the line c is directed to the point of use.
