Nach dem neuen Verfahren sollen die Verdampfungsflächen von Dampfkesseln vollkommen von Ablagerungen und Kesselstein befreit werden, ohne dafs es nöthig ist, den Kessel frei zu legen, oder auch nur ihn aufser Betrieb zu setzen, gegebenenfalls sogar ohne den Druck in ihm zu verringern.According to the new process, the evaporation surfaces can be completely freed of deposits and scale by steam boilers, without the need for the To expose the boiler, or even just to put it on operation, possibly even without it to relieve the pressure in him.
Das neue Verfahren besteht im Wesentlichen darin, dafs durch die zu reinigenden Theile des Kessels ein starker Strom von in dem Kessel selbst erzeugtem Dampf entgegengesetzt zu der Richtung hindurchgeschickt wird, in welcher diese Theile des Kessels beim normalen Betriebe von Dampf und Wasser durchströmt werden. Das Verfahren wird in der Weise ausgeführt, dafs der zu reinigende Theil des Dampferzeugers von dem Wasserraum desselben abgesperrt und vollkommen entleert wird, worauf man durch diesen Theil den vom Kessel entnommenen Dampfstrahl treten läfst. Zur Absperrung der zu reinigenden Röhren vom Wasserraum, zur Entleerung derselben und zur Regelung des Dampfstromes dienen für diese Zwecke geeignet angeordnete Hähne oder dergl.The new method consists essentially in working through the parts to be cleaned of the boiler is opposed by a strong flow of steam generated in the boiler itself is sent through to the direction in which these parts of the kettle in normal Steam and water flow through establishments. The procedure is in the way stated that the part of the steam generator to be cleaned is removed from the water space of the same is shut off and completely emptied, whereupon the steam jet taken from the boiler is allowed to pass through this part. To shut off the pipes to be cleaned from the water space, to empty them and taps suitably arranged for this purpose are used to regulate the steam flow or the like.
Auf der Zeichnung sind einige zur Ausführung des vorliegenden Verfahrens eingerichtete Dampfkessel verschiedener Bauart schematisch dargestellt, und zwar zeigen Fig. 1 und 2 Dampferzeuger mit Wasserraum und e-förmig gebogenen Wasserrohren, Fig. 3 bis 5 andere Formen von Wasserröhrenkesseln, Fig. 6 einen gewöhnlichen Langsiederkessel.In the drawing, some are set up to carry out the present method Steam boilers of various types are shown schematically, namely FIG. 1 and 2 steam generators with water space and e-shaped bent water pipes, FIG. 3 to 5 other forms of water tube boilers, Fig. 6 an ordinary long boiler boiler.
Das neue Reinigungsverfahren ist insbesondere für Dampfkessel bestimmt, die aus einem cylindrischen Wasser- und Dampfsammler α und einer Verdampfungsrohrgruppe bestehen, die aus liegend U-förmig gebogenen Röhren b zusammengesetzt ist, deren beide Enden in Sammelkasten c und d ausmünden, welche mit dem Wasser- und Dampfsammler durch die Röhren e und f in Verbindung stehen. In jeder dieser Röhren ist ein Hahn g bezw. h oder dergl. zum Abschliefsen des Rohres angeordnet. Aufserdem ist am unteren Ende der Kammer c ein Ablafshahn i vorgesehen.The new cleaning method is intended in particular for steam boilers, which consist of a cylindrical water and steam collector α and an evaporation tube group, which is composed of horizontally U-shaped bent tubes b , both ends of which open into collecting boxes c and d, which with the water and steam collectors communicate through tubes e and f. In each of these tubes is a cock g respectively. h or the like. Arranged to terminate the pipe. In addition, a drain cock i is provided at the lower end of the chamber c.
Beim normalen Betriebe läuft das Wasser, wie durch die in vollen Linien gezeichneten Pfeile angedeutet, um; aus dem Wasserraum a strömt das Wasser dem unteren Sammelkasten c zu, steigt dann in den Röhren b unter Dampfbildung auf, und der gebildete Dampf strömt durch den oberen Sammelkasten d dem im oberen Theil des Kessels α vorhandenen Dampfraum zu.In normal operation the water circulates, as indicated by the arrows drawn in full lines; from the water chamber a flows through the water the lower collecting box to c, then rises in the tubes b under formation of steam, and the steam formed passes through the upper collector box d in the upper part of the boiler α to existing vapor space.
Wenn man den Dampferzeuger reinigen will, so schliefst man den Hahn g und sperrt hierdurch die zu reinigenden Röhren b von dem Wasserraum in α ab; hierauf öffnet man den Ablafshahn i. Der in dem Dampfraum des Kessels α und dem Sammelkasten d enthaltene Dampf strömt dann mit grofser Gewalt in der durch die punktirten Pfeile angedeuteten Richtung durch die Röhren b und durch den Ablafshahn i aus, reifst dabei den Kesselstein und die sonstigen Niederschläge von den Wandungen der Röhren los und führt sie durch den Ablafshahn i mit sich ins Freie. Die Menge hierbei gebrauchten Dampfes kann durch den Hahn h geregelt werden.If you want to clean the steam generator, you close the tap g and thereby shut off the pipes b to be cleaned from the water space in α ; then you open the drain cock i. The steam contained in the steam space of the boiler α and the collecting box d then flows with great force in the direction indicated by the dotted arrows through the tubes b and through the drain cock i , ripening the scale and other deposits from the walls of the tubes go and take it outside with you through the drainage tap i. The amount of steam used for this can be regulated by tap h .
Es ist zweckmäfsig, die Rohrgruppe in mehrere Abtheilungen zu theilen, damit dieIt is advisable to divide the pipe group into several sections so that the
