Description

Treppenrost mit Roststufen von bogenförmigem Querschnitt. Bei Treppenrostfeuerungen mit den bekannten geraden Roststäben rutscht die erdige Braunkohle schwer nach, und die Rostspalten werden durch Kohle und Asche verstopft. Infolge des schweren Nachrutschens überstürzt sich die Kohle zeitweise auf dem Rost, und es bildet sich eine ungleichmäßig starke Kohlenschicht. An den wenig bedeckten Stellen gelangt zu viel, an den stark bedeckten Stellen zu wenig Luft über den Rost. Die Verbrennung wird daher unwirtschaftlich, die Flamme schlägt zeitweise zurück, und die überschüssige Luft macht einen starken Zugbedarf erforderlich. Infolge des Verstopfens der Rostspalten verbrennen die Roststäbe, und die Schlacke setzt sich an dem glühenden Eisen fest.Step grate with grate steps of arched cross-section. With stair grate firing with the well-known straight grate bars, the earthy lignite slides with difficulty, and the cracks in the grate are clogged with coal and ash. As a result of the heavy As the coal slides, it rushes over the grate at times, and it forms an unevenly thick layer of coal. Arrived at the little covered areas too much, too little air over the grate in the heavily covered areas. The burn therefore becomes uneconomical, the flame flashes back temporarily, and the excess Air requires a lot of draft. As a result of the clogging of the grate crevices the grate bars burn and the slag clings to the red-hot iron.

Treppenroste mit den bekannten Roststäben von bogenförmigem Querschnitt haben eine geringe freie Rostfläche, weshalb die Feuerung eine große Gesamtrostfläche bekommen müßte.Step gratings with the well-known grate bars with an arched cross-section have a small free grate area, which is why the furnace has a large total grate area would have to get.

Um die freie Rostfläche bei. derartigen Treppenrosten zu vergrößern, werden die gewölbten Roststäbe nach vorliegender Erfindung in der Mitte unterhalb der Vorderkante der darüber liegenden Rostfläche mit einer Längsrinne versehen.To the free grate area. to enlarge such stair gratings, are the arched grate bars according to the present invention in the middle below the front edge of the grate surface above is provided with a longitudinal groove.

Die Abbildung zeigt zwei solche übereinanderliegende Roststäbe im Querschnitt. Der Luftzutrittsquerschnitt wird durch diese Rostausbildung vergrößert. Die Kohle gleitet auf dem Rost leicht nach, so daß die Kohlenschicht gleichmäßig stark bleibt, und die Stäbe werden durch die durchströmende Luft besonders unten an der vorderen Kante gut gekühlt.The figure shows two such grate bars, one on top of the other, in the Cross-section. The air inlet cross-section is enlarged by this grate formation. The coal slides easily on the grate so that the coal layer is even remains strong, and the rods are especially down due to the air flowing through them well cooled at the front edge.

In der Vertiefung jedes Stabes bleibt gleichzeitig glühender Brennstoff zurück, der die Aufrechterhaltung des Feuers unterstützt.At the same time, glowing fuel remains in the recess of each rod back to help keep the fire going.
