KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der in Fig. 1 bis 7 dargestellte Dampfüberhitzer besteht aus einer Gruppe von Doppelröhren, welche entweder, wie in Fig. 1 und 2 dargestellt, für sich allein ausgeführt und direct befeuert, oder, wie in Fig. 3 bis 7 dargestellt, in die Feuerzüge des betreffenden Dampfkessels eingebaut wird. Fig. 3 bis 7 zeigen zwar nur zwei Kesselarten, doch läfst sich die gezeichnete Anordnung mit geringfügigen Abänderungen bei allen Dampferzeugern einbauen.The steam superheater shown in Fig. 1 to 7 consists of a group of double tubes, which either, as shown in Fig. 1 and 2, carried out individually and directly fired, or, as shown in Fig. 3 to 7, in the flues of the steam boiler in question is installed. 3 to 7 show only two types of kettles, but the one drawn can be used Install the arrangement with minor modifications on all steam generators.
Das Hauptmerkmal der Neuerung besteht in der Anwendung von Doppelröhren, durch deren ringförmigen Querschnitt der Dampf strömt, während die Heizgase das Aufsenrohr A von aufsen und das ■ Innenrohr J von innen bestreichen. Durch diese Einrichtung wird nicht nur eine relativ grofse, sondern auch eine sehr wirksame Heizfläche gewonnen, da der von den beiden Rohren gebildete ringförmige Querschnitt so klein bemessen werden kann, dafs die denselben- ausfüllende bezw. durchströmende Dampfschicht vollkommen gleichmäfsig überhitzt wird.The main feature of the innovation is the use of double tubes, through whose ring-shaped cross-section the steam flows while the heating gases brush the outer tube A from the outside and the inner tube J from the inside. With this device, not only a relatively large, but also a very effective heating surface is obtained, since the annular cross-section formed by the two tubes can be dimensioned so small that the one filling or filling the same. steam layer flowing through is completely evenly overheated.
Jedes Doppelrohr hat an beiden Enden einen Abzweigstutzen f und fx, wodurch die Verbindung der Rohre unter sich mittelst Muffen, Flantschen oder in sonst geeigneter Weise bewirkt wird. Der aus dem Kessel kommende gesättigte Dampf tritt in der Pfeilrichtung in den Ueberhitzer ein, durchströmt denselben in Schlangenlinien und wird von hier aus nach der Verwendungsstelle geleitet. Erforderlichenfalls werden die einzelnen Ueberhitzungsrohre, wie in Fig. 5 bis 7 angedeutet, in verschiedenen Längen und der Bewegungsrichtung der Feuergase entsprechend winklig zu einander angeordnet. In den Fällen, wo bei zu starker Hitze eine Beschädigung der vorderen Rohrtheile zu befürchten steht, wird die punktirt angedeutete Schutzwand angewendet und dieselbe nöthigenfalls über die ganze Rohrlänge hinweggezogen. Die Doppelrohre können zur Vermehrung der Heizfläche mit Längs- und Querrippen ausgestattet werden.Each double pipe has a branch pipe f and f x at both ends, whereby the connection of the pipes to one another is effected by means of sleeves, flanges or in some other suitable manner. The saturated steam coming from the boiler enters the superheater in the direction of the arrow, flows through it in serpentine lines and is directed from here to the point of use. If necessary, the individual overheating tubes, as indicated in FIGS. 5 to 7, are arranged in different lengths and at an angle to one another, corresponding to the direction of movement of the fire gases. In those cases where there is fear of damage to the front tube parts from excessive heat, the protective wall indicated by dots is used, and if necessary it is drawn over the entire length of the tube. The double pipes can be equipped with longitudinal and transverse ribs to increase the heating surface.
