Description

Dampferzeuger, insbesondere für hohen Druck. Die Erfindung bezieht sich auf den zylindrischen Umlaufmantel für Dampferzeuger mit innenliegender Feuerung. Wenn der Umlauf des Wassers durch eine Pumpe bewirkt wird, dann- soll gemäß der Erfindung das obere Ende des Umlaufmantels über den Wasserspiegel hinausragen, und zwar so weit, daß das innerhalb des Mantels hochgedrückte Wasser auch die beheizte Fläche der Mantelwand kühlt, die oberhalb des Wasserspiegels liegt. Die Erfindung- ist- in der Zeichnung zur Darstellung gebracht. Es stellt Abb. r einen Höhenschnift eines-- Kessels dar, der aus einem Oberkessel a und einem Unterkessel b besteht, Abb. a einen teilweisen Horizontalschnitt. Der Oberkessel a hat als Ergänzung einen ,gleichachsigen Innenkessel c. Jeder dieser drei Kessel hat einen Umlaufmantel ,d. Alle drei Umlaufmäntel ragen mit ihrem oberen Ende über den Wasserspiegel hinaus. Das. Wasser wird durch ein Rohr e . abgesaugt und durch ein Rohr f in den nunmehr unten abgeschlossenen, ringförmigen Raum, der sich zwischen dem Umlaufmantel und einem Kesselmantel befindet, gedrückt. Dabei muß das hineingedrückte Wascser sich über den oberen Rand des Umlaufmantels ergießen, wobei es in den Dampfraum fällt. Das obere Ende des Umlaufmantels bildet demnach ein Wehr für das umlaufende Wasser. Durch das Heben, des Wassers über das Wehr wird .die sonst nur mit dem Dampf Sxn Berührung stehende Heizfläche, die oberhalb des Wasserspiegels liegt, dauernd gekühlt, so daß keine übermäßige Erhitzung eines Teiles der Kesselwand und keine dadurch hervorgerufende gefährliche Wärmespannung entstehen kann.Steam generator, especially for high pressure. The invention relates to the cylindrical circulating jacket for steam generators with internal firing. If the circulation of the water is effected by a pump, then, according to the invention, the upper end of the circulating jacket should protrude above the water level, to the extent that the water pushed up inside the jacket also cools the heated surface of the jacket wall that is above the Water level lies. The invention is shown in the drawing. Fig.r shows a vertical section of a - boiler, which consists of an upper boiler a and a lower boiler b , Fig.a a partial horizontal section. The upper boiler a has an equiaxed inner boiler c as a supplement. Each of these three boilers has a circulating jacket; All three circulation jackets protrude with their upper end above the water level. That. Water is passed through a pipe e. sucked off and pressed through a pipe f into the now closed, ring-shaped space, which is located between the circulating jacket and a boiler jacket. The pressed-in water must pour over the upper edge of the circulating jacket, where it falls into the steam space. The upper end of the circulating jacket thus forms a weir for the circulating water. By lifting the water over the weir, the heating surface, which otherwise only comes into contact with the steam and which is above the water level, is permanently cooled so that no excessive heating of part of the boiler wall and no dangerous thermal stress can arise.
