Description

Vorrichtung zur Regelung der Dampferzeugung in Dampfkesseln mittels der Speisevorrichtung. EA ist bekannt, daß bei Dampfkesseln eine Regelung des Wasserstandes und des Dampfdruckes dadurch möglich ist, daß man eine auf Erhaltung -des Wasserstan&s hinarbeitende, das Speiseventil steuernde Regelvorrichtung mit einer durch den Dampfdruck bewegten Regelvorrichtung verbindet, die bei übermäßigem Dampfdruck das gleiche Speiseventil öffnet, so daß durch Einströmenlassen von Kaltwasser in den Kessel der Dampfdruck zum Sinken gebracht wird. Diese Einrichtungen eignen sich demnach nur dazu, ein übermäßiges Steigen des Dampfdruckes im Kessel zu verhindern. Für einen wirtschaftlichen Betrieb des Kessels aper ist es erforderlich, die Dampferzeugung so regeln zu können, daß auch ein Sinken des Kesseldruckes unter den Normaldruck verhindert wird, und es ist bekannt, äaß man dies ohne Eingriff in die Feuerung dadurch erreichen kann, .daß man den Kessel nlit Wasser verschiedener Temperatur speist: =' Gegenstand der Erfindung ist eine Einrichtung, welche diese Regelung der Dampferzeugung .in einfacher und sicherer Weise ermöglicht. Die Vorrichtung besteht darin, daß der Kessel mit einer Kalt- und einer Heißspei.sevorrichtung versehen und in jede der Speiseleitungen eine Regelvorrichtung eingebaut.ist, von denen diejenige der Kaltspeisung auf gleichbleibenden Wasserstand, diejenige der Heißspeisung jedoch auf gleichbleibenden Kesseldruck hinarbeitet.Device for regulating the generation of steam in steam boilers by means of the feed device. EA is known to regulate the water level in steam boilers and the steam pressure is possible in that one has to maintain the water level Working regulating device controlling the feed valve with a steam pressure control device moving control device connects the same in the event of excessive steam pressure Feed valve opens so that cold water flows into the boiler the vapor pressure is brought to decrease. These facilities are therefore suitable only to prevent an excessive rise in the steam pressure in the boiler. For an economical operation of the boiler aper it is necessary to generate steam To be able to regulate so that the boiler pressure also falls below normal pressure prevented becomes, and it is known, one ate this without intervention in the furnace can be achieved by the fact that the boiler is filled with water in different ways Temperature feeds: = 'The subject of the invention is a device which this Control of steam generation. In a simple and safe way. The device consists in that the kettle is provided with a cold and a hot feed device and a control device is built into each of the feed lines, of which the the cold feed to a constant water level, that of the hot feed, however works towards constant boiler pressure.

Auf der Zeichnung ist ein Ausführungsbeispiel einer derartigen Vorrichtung schematisch dargestellt.The drawing shows an embodiment of such a device shown schematically.

Der Dampfkessel A wird durch zwei Speiseleitungen gespeist, von denen die eine ein Regelventil W enthält und zur Zuführung von Kaltwasser dient, während die andere ein Regelventil R enthält und Heißwasser zuzuführen hat. Das Regelventil W wirkt nach Art der bekannten Wasserstandsregler auf gleichmäßigen Wasserstand im Kessel, wogegen das Ventil R unter dem Einfluß des Kesseldruckes steht und auf Gleicherhaltung des Kesseldruckes hinarbeitet.The steam boiler A is fed by two feed lines, one of which one contains a control valve W and is used to supply cold water while the other contains a control valve R and has to supply hot water. The control valve W acts like the well-known water level regulator on a constant water level in the boiler, whereas the valve R is under the influence of the boiler pressure and opens Works towards maintaining the boiler pressure.

Sinkt also der Druck des Kessels A um ein geringes, so öffnet sich R in entsprechenden Maße und läßt heißes. Wasser in den Kessel strömen, so daß die Dampferzeugung gesteigert wird, bis der Druck wiederhergestellt ist. Die Einrichtung kann dabei so getroffen sein, daß mnit dem Öffnen bzw. Schließen des Ventils R das Ventil W gleichzeitig in entsprechendem Maße geschlossen bzw. geöffnet wird, um die Menge des zugeführten Speisewassers gegebenenfalls möglichst gleich zu erhalten.So if the pressure in boiler A drops a little, it opens R in appropriate proportions and leaves hot. Water flow into the kettle so that the Steam generation is increased until pressure is restored. The establishment can be made so that with the opening or closing of the valve R the Valve W is closed or opened at the same time to a corresponding extent to keep the amount of feed water supplied as equal as possible.

Es ist natürlich nicht erforderlich, daß zwei völlig getrennte Anschlüsse der Speiseleitungen am Kessel vorhanden sind, vielmehr genügt es, wenn die Speiseleitungen sich zwischen den Ventilen und dem Kessel vereinigen, also durch ein gemeinschaftliches Mündungsrohr an den Kessel angeschlossen sind.It is of course not necessary to have two completely separate connections the feed lines are present on the boiler, rather it is sufficient if the feed lines unite between the valves and the boiler, i.e. through a common one Muzzle tube are connected to the boiler.

Im vorstehenden ist der Einfachheit halber ausschließlich von Wasser und Dampf gesprochen, .doch kann es :sich auch um andere Substanzen oder Aggregatformen handeln.The foregoing is exclusively of water for the sake of simplicity and steam, but it can: also be other substances or aggregate forms Act.
