Description

Die Einführung von Dampf und die Vernebelung von eingespritztem Wasser unter den Rosten zum Zweck der Granulierung der Schlacke und der Rostkühlung ist eine in der Feuerungstechnik gebräuchliche Maßnahme.The introduction of steam and the misting of injected water is under the grates for the purpose of granulating the slag and cooling the grate a measure commonly used in combustion technology.

Es ist bekannt, Sprühdüsen unter den Rosten anzuordnen und entweder der Rostkonstruktion und einzelnen Rostteilen in regelbaren Mengen Wasser oder Dampf zuzuführen. Es ist auch bekannt, die Roststäbe auf wassergekühlten Rohren zu lagern.It is known to arrange spray nozzles under the grates and either the grate construction and individual grate parts in adjustable amounts of water or steam to feed. It is also known to support the grate bars on water-cooled pipes.

Bei mechanischen Muldenrostfeuerungen wird erfindungsgemäß, besonders im Hinblick auf die bei dieser Rostart eigentümliche Luftverteilung, vorgeschlagen, die normalerweise nicht durch die Verbrennungsluft gewühlten und daher gefährdeten Teile des Rostbelages dadurch zu schützen, daß unter den einzelnen Rostteilen Sprühdüsen zur Vernebelung von Wasser oder Dampf angeordnet sind. Diese Düsen werden an Rohren angebracht, die als Zuführungsleitungen für das Kühlmittel dienen und auf denen der Rostbelag selbst gelagert ist. Die Öffnungen der Sprühdüsen sind ihrerseits auf die gefährdeten Rostteile gerichtet.In the case of mechanical trough grate firing, according to the invention, in particular With regard to the air distribution peculiar to this type of rust, it is proposed that which are normally not buried through the combustion air and therefore endangered To protect parts of the grate covering by spray nozzles under the individual grate parts are arranged for atomizing water or steam. These nozzles are attached to pipes attached, which serve as supply lines for the coolant and on which the grate itself is stored. The openings of the spray nozzles are in turn aimed at the endangered rust parts.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt.The invention is shown in the drawing in an exemplary embodiment.

Abb. i zeigt die Anordnung einer Granuliervorrichtung in der seither bekannten und üblichen Bauart. Der Rostbelag a ist auf Rundeisen b gelagert. Das Kühlmittel wird durch eine Leitung c, die unterhalb des Rostes angeordnet ist, eingeführt. Abb. a veranschaulicht den Erfindungsgedanken. Der Rostbelag a ist auf den Zuführungsleitungen c für das Kühlmittel gelagert. Die Rohre sind mit Sprühdüsen d verseben. deren Öffnungen auf die gefährdeten Teile des Rostbelages gerichtet sind.Fig. I shows the arrangement of a granulating device in the since known and usual design. The grate covering a is mounted on round iron b. That Coolant is introduced through a line c located below the grate. Fig. A illustrates the idea of the invention. The grate coating a is on the supply lines c stored for the coolant. The pipes are sunk with spray nozzles d. their openings are aimed at the endangered parts of the grate.
