Description

Hohlrost aus wassergekühlten Rohren für Feuerungen Die Erfindung betrifft einen aus wassergekühlten Rohren bestehenden Hohlrost für Feuerungsanlagen, insbesondere für Kohlenstaubfeuerungen. Bei Einrichtungen dieser Art bestand der Nachteil, daß beim Öffnen der Ascheraumtüren einer Brennkammer Luft in den Ascheraum eintrat, wodurch Störungen in der Brennkammer bzw. Feuerung verursacht wurden. Man hat deshalb Mittel, z. B. Schieber, ersonnen, die die Zwischenräume der Rohre des Granulnerrostes abdecken, um bei dem "Ziehen der Asche Brennkammer und Aschenraum gegeneinander abzudecken und so den Eintritt von Außenluft in die Brennkammer zu verhüten.Hollow grate made of water-cooled pipes for furnaces The invention relates to a hollow grate consisting of water-cooled pipes for firing systems, in particular for pulverized coal firing. In devices of this type there was the disadvantage that When the ash chamber doors of a combustion chamber were opened, air entered the ash chamber, which caused malfunctions in the combustion chamber or furnace. That's why you have Means, e.g. B. slide, devised, which the spaces between the tubes of the Granulnerrostes cover in order to "pull the ash combustion chamber and ash chamber against each other." cover and thus prevent the entry of outside air into the combustion chamber.

Gegenüber diesen bekannten Abdeckmitteln hat der Erfindungsgegenstand den Vorzug größerer Einfachheit und der geringeren Beeinträchtig ing des Aschedurchfalles.Compared to these known covering means, the subject matter of the invention the advantage of greater simplicity and less impairment of ash diarrhea.

Nach der Erfindung besteht das Abdeckmittel der Zwischenräume der Kühlrohre darin, daß an den Rohren von außen einstellbare, mit Doppelflügeln versehene Stellplatten angebracht sind, die bei senkrechter Einstellung die Zwischenräume der Rohre zum Durchfall der Asche frei lassen, während sie beim Abziehen der Asche, waagerecht eingestellt, diese Zwischenräume luftdicht abdecken und somit eine geschlossene Wand zwischen dem Aschenraum und der Brennkammer bilden.According to the invention, the covering means consists of the spaces Cooling tubes in that on the tubes adjustable from the outside, provided with double wings Plates are attached to the gaps when set vertically the pipes to the diarrhea leave the ashes free while pulling off the ashes, set horizontally, cover these spaces airtight and thus a closed one Form a wall between the ash chamber and the combustion chamber.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Abb. i stellt einen Teil der Feuerungsan.lage im Längsschnitt, Abb. 2 den Querschnitt hierzu dar. Zwischen der Brennkammer B und dem Ascheraum A ist der mit Wasserumlauf versehene Hohlrost, der aus wassergekühlten Rohren a besteht, angeordnet. Dies kann zweckmäßig so geschehen, daß ein oder mehrere Rohrreihen über- und nebeneinander vorgesehen sind. Der Erfindung gemäß ist die untere Rohrreihe so gestaltet, daß über die einzelnen Rohre drehbare Doppelflügel b geschoben sind, -die'von außen her durch ein Getriebe c gedreht und eingestellt werden können. Diese Flügel b stehen während des Betriehes senkrecht, so daß also die herunterfallende Asche durch die Zwischenräume der Rohre a hindurch in den Ascheraum gelangen kann. Soll die Asche aus dem Raum A abgezogen werden, so werden die Doppelflügel b durch die Vorrichtung c in die waagerechte Lage eingestellt, so daß die Räume zwischen den Röhren a abgedeckt werden, und zwar luftdicht.Fig. I shows a part of the furnace system in longitudinal section, Fig. 2 the cross-section for this. Between the combustion chamber B and the ash chamber A, the hollow grate, which is provided with water circulation and consists of water-cooled pipes a, is arranged. This can expediently be done in such a way that one or more rows of tubes are provided one above the other and next to one another. According to the invention, the lower row of tubes is designed so that rotatable double wings b are pushed over the individual tubes, -die'can be rotated and adjusted from the outside by a gear c. These wings b are vertical during operation, so that the falling ash can pass through the spaces between the pipes a and into the ash chamber. If the ashes are to be withdrawn from the space A , the double wings b are set in the horizontal position by the device c, so that the spaces between the tubes a are covered, namely airtight.
