Description

Plan- oder Wanderrost mit in der Höhe zueinander versetzten Roststäben. Rostanlagen mit abwechselnd in der Höhe versetzt liegenden Roststäben bringen mancherlei Vorteile mit sich. Um im Gegensatz zu den bekannten Rostanlagen dieser Art auch der Brennstoffschicht oberhalb der die tiefer liegenden Roststäbe dachartig übergreifenden Köpfe der oberen Roststäbe eine genügende Luftzufuhr zu sichern, ist nach der Erfindung den Köpfen der oberen Roststäbe im wesentlichen der Querschnitt eines auf der Spitze stehenden Vierecks gegeben. Hierdurch wird in vorteilhafter Weise erreicht, daß eine über die ganze Rostfläche reichende ungehinderte Luftzufuhr zur Brennstoffschicht stattfinden kann.Flat or traveling grate with grate bars offset from one another in height. Grate systems with grate bars that are alternately offset in height bring a lot of things Advantages with itself. To, in contrast to the well-known grate systems of this type, too the fuel layer above the roof-like overlapping the lower grate bars Ensuring a sufficient air supply heads of the upper grate bars is according to the invention the heads of the upper grate bars are essentially the cross-section of one on the top standing square. This is achieved in an advantageous manner that an unimpeded air supply to the fuel layer extending over the entire grate surface can take place.

Auf der Zeichnung ist ein Ausführungsbeispiel des Rostes in Abb. i als Planrost, in einem Flammrohre eingebaut, dargestellt; Abb.2 zeigt einen Teil des Rostes in vergrößertem Maßstabe.The drawing shows an embodiment of the grate in Fig. I shown as a plan grate installed in a flame tube; Fig.2 shows a part of the grate on a larger scale.

In Aussparungen des Roststabquerträgers i ruhen die Roststäbe 2 und 3, die verschieden hoch sind, wobei sich zwischen je zwei hohen Roststäben 2 ein niedriger Roststab 3 befindet. Erstere haben im wesentlichen den Querschnitt eines auf der Spitze stehenden Vierecks, während die Roststäbe 3 eine konvexe Oberfläche besitzen. An den unteren oder auch an den oberen Roststäben befinden sieh Ansätze q., so daß zwischen den Roststäben Spalten 5 zum Zuführen der Luft verbleiben.The grate bars 2 and rest in recesses in the grate bar cross member i 3, which are of different heights, with 2 between each two high grate bars lower grate bar 3 is located. The former have essentially the cross-section of a on the top standing quadrilateral, while the grate bars 3 have a convex surface own. There are approaches on the lower or also on the upper grate bars q., so that gaps 5 remain between the grate bars for the supply of air.

Die obere Rostfläche dient zur Verbrennung, während die untere Rostfläche eine starke Wirbelung der Luft hervorruft, so daß eine vollkommene Verbrennung erzielt wird. Es entstehen keine toten Ecken, und es wird eine große freie Rostfläche erreicht. Es kann auch ohne Durchfallverluste feinkörniger Brennstoff verfeuert werden. Krater und Stich$ammbildungen sowie tote Streifen werden vermieden.The upper grate surface is used for combustion, while the lower grate surface causes a strong turbulence in the air, so that a perfect combustion is achieved will. There are no dead corners and a large free grate area is achieved. Fine-grain fuel can also be burned without loss of diarrhea. crater and prick amuletas as well as dead streaks are avoided.

Die Roststäbe können in Quer- oder Längsrichtung angeordnet sein.The grate bars can be arranged in the transverse or longitudinal direction.
