Description

Dampfkessel, insbesondere für hohen Druck. In der Erfindung nach dem Hauptpatent 432115 ist in dem ringförmigen Kesselraum ein Mantel angeordnet, der den Umlauf des Wassers, der infolge von Gewichtsunterschieden auftritt, verstärken soll. Die neue Erfindung bezieht sich darauf, den Wasserumlauf noch mehr zu verstärken, so daß das Wasser irgendeine den Anforderungen des Betriebes entsprechende Geschwindigkeit annehmen kann.Steam boilers, especially for high pressure. In the invention according to the Main patent 432115 a jacket is arranged in the annular boiler room, the increase the circulation of water that occurs as a result of weight differences target. The new invention relates to increasing the water circulation even more, so that the water has any speed appropriate to the requirements of the operation can accept.

Bei Hochdruckkesseln ist es außerordentlich vorteilhaft, daß alle Teile des Kessels gleichmäßig erwärmt werden, damit keine Spannungen im Material auftreten. Außerdem ist es für die Ausnutzung der beheizten Fläche und damit für die Leistung des Kessels von großem Vorteil, wenn die sich ansetzenden Dampfblasen weggespült werden. Ferner bedeutet der rasche Wechsel des die Heizwand berührenden Wassers eine Beschleunigung der Wärmeübertragung. Diese drei Vorteile werden durch die genannte Anordnung des Mantels i (Abb. i und Abb. 2) erstrebt und in gewissem Maße auch erreicht. Das Neue gegenüber Vorrichtungen bekannter Art zur Erhöhung des Wasserumlaufs besteht in dem ringförmigen Pumpenkolben 2, der von außen mittels der beiden Stangen 3 und 3a angetrieben wird. Der Kolben 2 ist mit Löchern 4 versehen, die durch Klappen 5 zugedeckt werden, wenn der Kolben sich nach unten bewegt.In the case of high pressure boilers, it is extremely advantageous that all Parts of the boiler are heated evenly so that there are no tensions in the material appear. It is also used for the use of the heated area and thus for the performance of the boiler is of great advantage when the accumulating steam bubbles be washed away. Furthermore, the rapid change of the one in contact with the heating wall means Water accelerates heat transfer. These three advantages are made possible by the aforementioned arrangement of the jacket i (Fig. i and Fig. 2) strives and to a certain extent Dimensions also achieved. The new compared to devices of known type for increasing of the water circulation is in the annular pump piston 2, which is from the outside by means of the two rods 3 and 3a is driven. The piston 2 is provided with holes 4, which are covered by flaps 5 when the piston moves downwards.

Das Wasser wird sich demnach in dem äußeren Ringraum nach unten und in dem inneren nach oben bewegen, hier also in der Richtung des Aufsteigens der Dampfblasen. Durch den beschleunigten Wasserumlauf wird das Auftreten von Materialspannungen, die durch ungleichmäßige Erwärmung entstehen können, gänzlich vermieden. Ferner werden die Dampfblasen durch den Strom beständig mitgerissen, so daß sie nicht an der Kesselwand haften können. Außerdem wird die Wärmeübertragung von der Kessel-,vand auf das Wasser durch dessen raschen Wechsel beschleunigt. Der Kolben 2 kann an Stelle der einzelnen Klappen mit einer Ringabdeckung versehen sein, die den erforderlichen Spielraum hat. Ein etwaiges Versagen der Antriebsvorrichtung der Pumpe würde einen fast gänzlichen Stillstand des Wasserumlaufs zur Folge haben, wobei die genannten Vorteile sofort aufhören würden. Um dies zu verhindern, kann die Antriebsvorrichtung so eingerichtet sein, daB der Kolben selbsttätig oder von Hand so weit in die Höhe gehoben wird, daB er sich im Dampfraum befindet, wonach der auf Gewichtsunterschiede beruhende Wasserumlauf einsetzen kann. Eine ebensolche Pumpeinrichtung kann für den kleinen, inneren Kessel vorgesehen werden.The water will therefore move downwards and in the outer annulus move upwards in the interior, here in the direction of the ascent of the Steam bubbles. Due to the accelerated water circulation, the occurrence of material tension, which can arise from uneven heating, are completely avoided. Further the vapor bubbles are constantly carried away by the current, so that they do not come on can stick to the boiler wall. Also, the heat transfer from the boiler, vand on the water accelerated by its rapid change. The piston 2 can be provided with a ring cover instead of the individual flaps, which has the necessary leeway. Any failure of the drive device the pump would result in an almost complete standstill of the water circulation, whereby the mentioned advantages would stop immediately. To prevent this, you can the drive device can be set up so that the piston is automatic or from Hand is raised so high that it is in the steam room, after which the water circulation based on weight differences can start. Such a one Pump equipment can be provided for the small, inner boiler.
