PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft einen Dampfüberhitzer mit in Richtung des Dampfdurchflusses abnehmenden Rohrquerschnitten. Der Überhitzer besteht in bekannter Weise aus einem System durch Kopfstücke verbundener flach gedrückter Rohre. Das Wesen der Erfindung gegenüber bekannten ähnlichen Einrichtungen besteht darin, daß die Verengerung der Querschnitte durch Flachdrücken derThe present invention relates to a steam superheater with pipe cross-sections decreasing in the direction of the steam flow. The superheater is made in a known manner a system of flattened pipes connected by head pieces. The essence of the invention versus known similar devices is that the narrowing of the cross-sections by flattening the
ίο Rohre in elliptische Form bewirkt vvird.^ Die Herstellung des Überhitzers wird sehr vereinfacht, da die Röhren alle aus einem runden Normalprofil hergestellt werden können und durch einfaches Flachdrücken in die elliptische Form dem Rohre die gewünschte Querschnittsverringerung erteilt wird. Außerdem wird durch diese Rohre der Wärmeaustausch erhöht.ίο tubes in elliptical shape causes vvird. ^ the Manufacture of the superheater is very simplified because the tubes are all round Normal profile can be made and by simply flattening it into the elliptical Shape the pipes are given the desired reduction in cross-section. In addition, the heat exchange takes place through these pipes elevated.
In der Zeichnung zeigtIn the drawing shows
Fig. ι den Überhitzer im Längsschnitt,
Fig. 2 einen Querschnitt.Fig. Ι the superheater in longitudinal section,
Fig. 2 is a cross section.
Die Uberhitzerrohre a, die in die zweckmäßig aus Stahlguß hergestellten Uberführungskammern b eingewalzt sind, haben einen flach oder oval gedrückten Querschnitt.The superheater tubes a, which are rolled into the transfer chambers b expediently made of cast steel, have a flat or oval cross-section.
Handelt es sich um liegende Überhitzer, so werden die Rohre so angeordnet, daß die lange Achse der Rohrquerschnitte senkrecht und somit die schmale Seite der Rohre nach oben zu liegen kommt, so daß der Flugasche eine möglichst kleine Fläche zur Ablagerung geboten wird, was ein nicht zu unterschätzender Vorteil dieses Systems ist.If it is a horizontal superheater, the tubes are arranged so that the long axis of the pipe cross-sections perpendicular and thus the narrow side of the pipes comes to lie on top, so that the fly ash as small an area as possible to deposit what is offered is an advantage of this system that should not be underestimated.
