Description
Vorrichtung zur Erzwingung geordneter Strömungsrichtung und Beschleunigung des Wasserumlaufs in Wasserrohrdampfkesseln. Die Erfindung, betrifft eine Vorrichtung zur Erzwingung von geordneten Strömungsrichtungen in Dampfkesseln beliebiger Bauart, unter gleichzeitiger Beschleunigung des Flüssigkeitsumlaufs.Device for enforcing orderly flow direction and acceleration of the water circulation in water tube steam boilers. The invention relates to a device to enforce orderly flow directions in steam boilers of any type, with simultaneous acceleration of the fluid circulation.
Bisher hat mann durch entsprechende Anordnung von Steig- und Fallrohren, in Verbind'ung mit Ober- und Untertrommeln, die Strömungsverhältnisse in Dampfkesseln zu beherrschen versucht, wobei man auch Steig-und Fallrohre injektorartig zusammenschaltete. Die Erfahrung zeigte aber, daß durch derartige Maßnahmen die gewollte 'Wirkung nicht in erwünschtem Maße eintrat, besonders wenn Schwankungen der Dampfentnahme oder der Feuerführung auftreten.So far, by arranging risers and downpipes accordingly, in connection with the upper and lower drums, the flow conditions in steam boilers Tried to control, whereby one also interconnected riser and downpipes like an injector. Experience has shown, however, that such measures do not have the intended effect occurred to the desired extent, especially when fluctuations in steam extraction or the fire control occur.
Auf Grund dieser Erfindung wird das Problem jedoch vollkommen gelöst und das beruht darauf, daß die Speisung der Steigrohre mit zu verdampfender Flüssigkeit, unter Verwendung von Rückschlagventilen vorgenommen wird, die sich beim Eintritt oder Beginnenwollen des Eintritts einer unerwünschten rückläufigen Wasserbewegung mehr oder weniger schließen oder mehr oder weniger großen Strömungswiderstand erzeugen, so daß keine oder keine schädliche Rücklaufbewegung des zu verdampfenden Wassers erfolgt.However, this invention completely solves the problem and that is based on the fact that the supply of the riser pipes with liquid to be evaporated, is made using check valves, which are located on entry or wanting to initiate undesirable retrograde water movement close more or less or generate more or less large flow resistance, so that no or no harmful return movement of the water to be evaporated takes place.
Diese Rückschlagventile können an beliebiger Stelle der 1~'a11- oder Steigrohre oder in bezug auf die Kesseltrommeln angeordnet sein.These check valves can be placed anywhere on the 1 ~ 'a11- or Riser pipes or be arranged with respect to the boiler drums.
Abb. i zeigt einen Kessel, Bauart Maas, bei dem zehn Steigrohre a durch ein Fallrohr b über das Rückschlagventil d gespeist werden.Fig. I shows a boiler, type Maas, in which ten riser pipes a are fed through a downpipe b via the check valve d.
Auf der linken Hälfte der Abb. i ist das Rückschlagventil am unteren Ende des Fallrohres b, auf .der rechten Seite der Abb. i dagegen am oberen Ende des Fallrohres b angeordnet.On the left half of Fig. I, the check valve is at the bottom End of the downpipe b, on the right side of Fig. I, however, at the upper end of the downpipe b arranged.
Das Dampfflüssigkeitsgemisch kann durch Rohre e unmittelbar in den Dampfraum des Oberkessels f geleitet werden, so daß die Flüssigkeit des Oberkessels nur über die Fallrohre b in die Steigrohre u gelangen kann.The steam-liquid mixture can e directly into the through pipes Steam space of the upper boiler f are passed, so that the liquid of the upper boiler can only reach the riser u via the downpipes b.
Abb. z zeigt einen beliebigen Steilrohrkessel, wobei a wieder das Steig- und b das Fallrohr ist. Die Rückschlagventile d sind hier z. B. im Unterkessel g angeordnet. Auch hier können die Steigrohre a unmittelbar in den Dampfraum des Oberkessels f geleitet werden oder nicht.Fig. Z shows any vertical tube boiler, with a again being the ascending pipe and b being the down pipe. The check valves d are here z. B. arranged in the lower boiler g. Here, too, the riser pipes a can be passed directly into the steam space of the upper boiler f or not.
Da keine Rücklaufbewegung des Wassers eintreten und die durch mehr oder wenigeres z. B. Schließen der Rückschlagventile entstehende Drucksteigerung beschleunigtes Entleeren der Steigrohre bedingt, ergibt sich eine große Steigerung der Umlaufgeschwindigkeit.Since there is no return movement of the water and through more or less z. B. Closing the check valves resulting pressure increase Due to the accelerated emptying of the riser pipes, there is a large increase the speed of rotation.
Die Erfindung kann auch ohne Verwendung von unteren Kesseltrommeln angewandt werden, so daß die Wasserrohre vom Oberkessel in den Feuerraum und von da zur Obertrommel, oder zur anderen, zurückführen, wobei das Rückschlagventil an beliebiger Stelle dieses Rohres angeordnet sein kann. Derartige Rohre können verschiedene Durchmesser haben.The invention can also be used without the use of lower kettle drums be applied so that the water pipes from the upper boiler to the furnace and from there lead back to the upper drum, or to the other, with the non-return valve on can be arranged at any point of this tube. Such tubes can be different Have diameter.
