KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei den bisher versuchten Einrichtungen zum selbstthätigen Entfernen der Flugasche aus den Flammrohren der Dampfkessel mittelst des Zuges tritt in der Regel eine wesentliche Verengung des Rohrquerschnittes ein. Das Patent No. 937 betrifft z. B. die Anbringung eines zuckerhutförmigen Kernes in den Flammrohren, die mit schraubenförmigen Flügeln besetzt sind; um den Querschnitt des eingesetzten Kernes wird daher bei bestehenden Kesseln der Querschnitt des Flammrohres verengt.In the devices tried so far for the automatic removal of the fly ash from the The flame tubes of the steam boilers by means of the draft are, as a rule, considerably narrowed of the pipe cross-section. The patent no. 937 relates to e.g. B. the attachment of a sugar-loaf-shaped core in the flame tubes, which are studded with helical wings; the cross-section of the core used is therefore the cross-section of existing boilers of the flame tube narrowed.
Zur Vermeidung dieses Nachtheiles setzt der Patentinhaber eine aus Thon, Eisen oder anderem Material hergestellte, doppelschneckenartige, kurze, Y2 bis 3/4 eines Gewindeganges ausmachende Fläche α in den vorderen Theil des Flammrohres ein, und zwar bei Vorfeuerung möglichst nahe dem Anfang des Flammrohres, wie Fig. ι zeigt; bei Innenfeuerung thunlichst nahe der Feuerbrücke, wie Fig. 2 zeigt.To avoid this night salvation the patentee employs a of clay, iron or other material prepared, double-screw-like, short, y is 2 to 3/4 of a thread making up area α in the front part a of the flame tube, and that at Vorfeuerung as close as possible to the beginning of the flame tube , as Fig. ι shows; with internal firing as close as possible to the fire bridge, as Fig. 2 shows.
Diese Fläche ist so dünnwandig wie möglich construirt, so dafs die Verengung des Querschnittes sehr gering ist. Indem die Feuergase diesen kurzen Schneckentheil passiren, werden sie in eine wirbelnde Bewegung versetzt, welche bei nicht zu langen Flammrohren bis an das Ende der letzteren anhält und die Flugasche mit herauswirbelt. Bei längeren und sehr langen Flammrohren empfiehlt sich die Einsetzung eines zweiten bezw. dritten Schneckentheiles, um der wirbelnden Bewegung der Feuergase neuen Impuls zu geben und dadurch die Fortführung der Flugasche aus dem Flammrohre zu sichern.This surface is constructed as thin-walled as possible, so that the narrowing of the cross-section is very low. As the fiery gases pass this short section of the snail sets them in a whirling motion, which if the flame tubes are not too long up to the The end of the latter stops and the fly ash is swirled out with it. For longer and very long ones Flame tubes recommend the use of a second respectively. third part of the snail, to give the swirling movement of the fire gases new impulse and thereby the continuation to secure the fly ash from the flame tubes.
Es empfiehlt sich aber unter allen Umständen, nur möglichst wenig Einsätze anzuordnen, um die Reibungswiderstände, die sie dem Zuge bieten, möglichst zu verringern.However, it is advisable under all circumstances to arrange only as few bets as possible, in order to reduce the frictional resistance they offer the train as much as possible.
Durch die Einsätze werden die heifseren Feuergase, welche bei einem gewöhnlichen Flammrohr in dessen oberem Theile hinziehen, mit den weniger heifsen Feuergasen am Boden des Flammrohres gemischt. Diese. Mischung soll eine gleichmäfsigere Geschwindigkeit der sämmtlichen Feuergase und eine Verhinderung der Ablagerung der Flugasche zur Folge haben.Through the inserts the hotter gases of the fire, which with an ordinary Draw the flame tube in its upper part, with the less hot fire gases on the bottom of the flame tube mixed. These. Mixing should have a more uniform speed of the all fire gases and a prevention of the deposition of the fly ash result.
