Description

Um die unkondensierbaren Gase aufs Heizkammern zu entfernten, welche den Wärmeübertragungskoeffizienten herabsetzen, wurden in der Mitte derselben auf dem oberen Rohrboden mehrere Gasabzugsstutzen angebracht. Diese Gasal>zugsstutzen hatten aber nicht den gewünschten Erfolg denn nnr die Gase, welche in der Strömungsrichtung des Dampfes sich befanden, wurden abgeführt. To remove the non-condensable gases on the heating chambers, which lowering the heat transfer coefficient were in the middle of the same several gas outlet nozzles are attached to the upper tube sheet. This Gasal> Zugsstutzen but did not have the desired success except for the gases which flow in the direction of flow of the steam were removed.

Dlie Räume, welche vom Dampf nicht bestrichen wurden, füllten sich mit Gasen auf, und die Heizrohre waren als Heizfläche unwirksam.The rooms, which were not smeared by the steam, filled up with gases, and the heating pipes were ineffective as a heating surface.

Um diesen Mangel zu beseitigen, wurden die Heizkammern mit Leitbi echen versehen, welche bewirken sollten, daß der Dampf die unkondensierbaren Gase nach einer Stelle drückt, von wo sie abgezogen werden können. Diese Leitbleche hatten aber den Nachteil, daß sich hinter denselben erst recht viele Stellen bildeten, wo der Dampf zur Ruhe kam, und es waren erst recht viele Gasahzugs stutzen erforderlich, welche wiederum große Dampfverluste mit sich brachten. In order to remedy this deficiency, the heating chambers with Leitbi provided that should cause the steam to remove the non-condensable gases pushes for a point from where they can be pulled off. These baffles had but the disadvantage that a lot of places were formed behind them, where the steam came to rest, and a lot of throttle stubs were required, which in turn brought great steam losses with it.

Man hat versucht, vorstehende Mängel durch Anbringung mehrerer am Umfang verteilter Dampfstutzen von verschiedenem Querschnitt zu beseitigen, welche bewirken sollten, daß die Heizkammer überall gleichmäßig mit Dampf beschickt wird. Außerdem brachte man in verschiedenen Höhen Gasabzugsstutzen an, um hier die Gase mit verschiedenen spezifischen Genvichten abzuführen. Attempts have been made to remedy the above defects by attaching several on To eliminate circumference of distributed steam nozzles of different cross-section, which should ensure that the heating chamber is evenly charged with steam everywhere. In addition, gas outlet nozzles were installed at different heights to allow the gases here with different specific gene densities.

Auch diese Einrichtung brachte nicht den vollen Erfolg, denn der Dampf nahm den Weg des geringsten Widerstandes nach dem Gasabzugsstutzen.This facility did not bring complete success either, because the steam took the path of least resistance to the gas vent.

Es bildeten sich in den Räumen, die nicht in der Strömungsrichtung des Dampfes lagen, Gasansammlungen.It formed in the spaces that were not in the direction of flow of the steam, accumulations of gas.

Um eine möglichst vollkomYnene Abführung der unkondensierbaren Gase zu erzielen, muß der Weg und damit der Widerstand, welcher dem Dampf entgegengesetzt wird, in allen Teilen der Heizkammer mögllichst gleich sein. To achieve the most complete possible removal of the non-condensable gases To achieve this, the path and thus the resistance which opposes the steam must be taken will be the same as possible in all parts of the heating chamber.

Durch vorliegende Erfindung wird ein nach der Mitte der Heizkammer gerichteter Dampfstrom erreicht. Hierdurch werden die unkondens ierbaren Gase vollkommen aus der Heizkammer entfernt, und es wird eine größtmögliche Wirksamkeit der Heizfläche erzielt. The present invention provides one after the middle of the heating chamber directed steam flow achieved. This makes the non-condensable gases complete removed from the heating chamber, and there will be maximum effectiveness of the heating surface achieved.

Die Erfindung ist in der Zeichnung schematisch dargestellt. The invention is shown schematically in the drawing.

Abb. I zeigt einen senkrechten Schnitt durch die Heizkammer; Abb. 2 zeigt einen Querschnitt nach der Linie I-I der Abb. I. Fig. I shows a vertical section through the heating chamber; Fig. 2 shows a cross section along the line I-I of Fig. I.

Zur Bildung einer Entlüftungskammer und damit zur Erzielung eines gleichmäßigen Dampfstromes ist über dem Zirkulationsrohr a der Abb. I ein zweites größeres Rohr b angebracht, welches Durchbohrung besitzt. Durch dieses zweite weitere Rohr wird somit in der Mitte der Heizkammer eine ringförmige Kammer gebildet. Damit der Heizdampf sämtliche Rohre c gleichmäßig bestreicht, ist es zweckmäßig, daß durch Wegfall von Rohren am äußeren Dampfmantel d ein Dampfraum gebildet wird. Von diesem Dampfraum strömt der Dampf gleichmäßig nach der Mitte, verdichtet sich und drückt die unkondensierbaren Gase durch die Durchbohrungen des Rohres b in die ringförmige Entlüftungskammer. Von dieser ringförmigen Entlüftungskammer werden die unkondensierbaren Gase je nach dem spezifischen Gewicht in verschiedenen Höhen angebrachten Abzugs rohren e nach außen geleitet. To form a ventilation chamber and thus to achieve a uniform steam flow is above the circulation pipe a in Fig. I a second larger tube b attached, which has a through hole. Through this second further An annular chamber is thus formed in the middle of the heating chamber. In order to the heating steam evenly sweeps all tubes c, it is useful that through Elimination of pipes on the outer steam jacket d a steam space is formed. Of this In the steam room, the steam flows evenly towards the center, compresses and presses the non-condensable gases through the bores of the tube b into the annular Vent chamber. From this ring-shaped vent chamber, the non-condensable Gases installed at different heights depending on the specific weight pipes e routed to the outside.

Stutzen f dient für den Dampfeintritt, Stutzen g für den Kondensataustritt. Connection f is used for the steam inlet, connection g for the condensate outlet.

Zur besseren Dampfverteilung ist in der Heizkammer noch ein Siebblech h in üblicher Weise angebracht. There is also a sieve plate in the heating chamber for better steam distribution h attached in the usual way.
