KLASSE 13: Dampfkessel nebst Ausrüstung.CLASS 13: Steam boiler and equipment.
Patentirt im Deutschen Reiche vom 21. August 1886 ab.Patented in the German Empire on August 21, 1886.
Der auf beiliegender Zeichnung dargestellte Zugregulator soll sich vor anderen dem gleichen Zwecke dienenden Apparaten durch seine grofse Einfachheit bei durchaus sicherem Gange auszeichnen und zur selbsttätigen Regulirung der Luft-Zu- und Rauch-Abführung für Niederdruckdampfkessel dienen, welche mit einem Füllschacht für das Brennmaterial versehen sind.The tension regulator shown in the accompanying drawing should be the same before others Purpose-serving apparatus by its great simplicity with thoroughly safe operation and for the automatic regulation of the air supply and smoke discharge for low-pressure steam boilers serve, which are provided with a filling shaft for the fuel.
Dieser Apparat besteht aus einer sich um eine Achse drehenden Trommel A, dem oben gekrümmten, an das zur Speisung des Kessels dienende Rohr angeschlossene, ca. 3 m hohe Füllrohr B, dem mit Rückschlagventil versehenen Rücklaufrohr C und dem an einer Kette G hängenden Gewicht D zum Ausbalanciren der Verschlufsklappen E. This apparatus consists of a drum A rotating around an axis, the top-curved, approx. 3 m high filling pipe B connected to the pipe serving to feed the boiler, the return pipe C with a non-return valve and the weight D hanging on a chain G. for balancing the closing flaps E.
Die Wirkungsweise des Regulators ist- folgende: Brennt das Feuer auf dem Rost J zu lebhaft und wird dadurch die Dampfentwickelung im Verhältnifs zum Verbrauch zu grofs, so steigt das Wasser in dem Rohr B bis zu 3 m (entsprechend 0,3 at Druck) und fliefst in das Fach F der Trommel. Infolge dessen dreht sich dieselbe und schliefst vermittelst der Kette G, welche an der höchsten Stelle der Trommel durch einen Stift befestigt ist, die Klappen E, was erleichtert wird durch die Möglichkeit des freien Entweichens der Luft aus dem Fach F durch den Gummischlauch H. Durch diesen Vorgang wird der Luftzutritt und der Rauchabzug abgeschlossen, so dafs das Feuer weniger lebhaft brennt und dementsprechend sich weniger Dampf entwickelt. Die ,Folge hiervon ist, dafs das Wasser infolge des geringeren Druckes im Rohr B bis unter das Rohr C sinkt, worauf das Wasser aus dem Hahn F das Rückschlagventil R V öffnen und wieder in den Kessel zurückfliefsen kann. Hierdurch wird die Trommel wieder leichter und durch das Gegengewicht K wird sie in ihre alte Lage gebracht, um die Function von neuem beginnen zu können.The mode of operation of the regulator is as follows: If the fire on the grate J burns too vigorously and if this causes the development of steam to be too great in relation to the consumption, the water in pipe B rises up to 3 m (corresponding to 0.3 at pressure) and flows into compartment F of the drum. As a result, the same rotates and closes by means of the chain G, which is attached to the highest point of the drum by a pin, the flaps E, which is facilitated by the possibility of free escape of air from the compartment F through the rubber hose H. Through This process closes the air inlet and the smoke outlet, so that the fire burns less vigorously and, accordingly, less steam develops. The consequence of this is that the water sinks as a result of the lower pressure in pipe B to below pipe C, whereupon the water from tap F can open the check valve RV and flow back into the boiler. This makes the drum lighter again and the counterweight K brings it into its old position so that the function can be started again.
