Description
Als Planrost zu benutzender muldenförmiger Rost. Die Durchfallverluste bei der Verfeuerung grießiger Kohle können durch Anordnung wagerechter Rostspalten vermindert werden; so ist aus dem Schrägrost der Treppenrost entstanden. Wenn man einen Planrost mit senkrechten Spalten in einen Rost mit wagerechten Spalten umbildet, dann wird die Brennebene zu einer flachen Mulde, in der jedoch die Kohle nicht nachrutscht. Infolge der Mulden- und Spaltenform prallen die Heizgase in der Feuermitte zusammen und erzeugen unter guter Durchwirbelung eine vollkommene Verbrennung auch minderwertiger Brennstoffe.Trough-shaped grate to be used as a flat grate. The diarrhea losses When firing coarse coal, horizontal grate gaps can be arranged be decreased; this is how the step grating was created from the inclined grating. If converts a flat grate with vertical gaps into a grate with horizontal gaps, then the focal plane becomes a shallow trough in which, however, the coal does not slide. Due to the shape of the trough and crevice, the heating gases collide in the middle of the fire and produce a perfect combustion, even of inferior quality, with good circulation Fuels.
Während aber auf einem Planrost üblicher Bauart die Schicht an allen Stellen gleiche Dicke hat, entsteht beim Muldenrost in der Mitte eine Brennstoffhäufung, die hier eine stärkere Luftzufuhr bedingt. Durch Erweiterung der mittleren Spalten - darin liegt das Merkmal dieser Erfindung - läßt sich ein auf der ganzen Rostfläche gleichmäßiger Abbrand erzielen.But while on a flat grating of the usual type, the layer on all Places has the same thickness, fuel accumulates in the middle of the hollow grate, which here requires a stronger air supply. By widening the middle columns - therein lies the feature of this invention - can be one on the whole grate surface achieve even burning.
Durch die wagerechten Spalten tritt die Verbrennungsluft in der Ebene des Feuers in dasselbe ein, wodurch insbesondere bei Verwendung von Unterwind die Bildung von Stichflammen vermieden wird, welche bei senkrecht zur Feuerebene gerichteter Luftzufuhr häufig auftreten.The combustion air passes through the horizontal gaps on the level of the fire in the same one, whereby especially when using underwind the Formation of flashes is avoided, which is directed perpendicular to the plane of fire Air intakes often occur.
Die Zeichnung zeigt den Querschnitt eines Ausführungsbeispieles. In passenden Ausnehmungen der Querträger b ruhen die Roststäbe mit senkrechten Stegen c, ihre wagerechten Teile a übergreifen einander, so daß die Spalten d, deren Weite durch schmale Nasen f gesichert ist, die Brennluft zur Rostmitte leiten. Es gibt demnach keine toten Streifen, wie bei Rosten mit senkrechten Spalten, wo die Dicke der Stäbe den auf ihnen liegenden Brennstoff der Luftströmung zu entziehen pflegt. Der als Doppelstab aus einem Stück gegossene Mittelstab g ruht mit Stegen h ebenfalls auf den Querträgern b.The drawing shows the cross section of an embodiment. The grate bars with vertical webs c rest in matching recesses in the cross members b, their horizontal parts a overlap one another so that the gaps d, the width of which is secured by narrow lugs f , direct the combustion air to the center of the grate. There are therefore no dead stripes, as is the case with grids with vertical gaps, where the thickness of the rods tend to withdraw the fuel lying on them from the air flow. The central bar g, cast from one piece as a double bar, rests with webs h also on the cross members b.
Beim Durchtritt kühlt die Luft die Stäbe, dabei erwärmt sie sich. Die Roststäbe nahe der Mitte haben höhere Nasen f als die äußeren Stäbe, durch die dort weiteren Spalten erfolgt eine stärkere Luftzufuhr als an den Rändern, und daraus ergibt sich trotz ungleicher Schichtdicke eine günstige Verbrennung.As it passes through, the air cools the rods and warms up in the process. The grate bars near the center have higher noses f than the outer bars through which there further gaps there is a stronger air supply than at the edges, and from it This results in favorable combustion despite the unequal layer thickness.
Bei sehr weitem Feuerraum sieht man mehrere Roste dieser Art nebeneinander vor. In besonderen Fällen kann die Mulde quer zur Aufwurfrichtung angeordnet werden.If the firebox is very wide, you can see several grates of this type next to each other before. In special cases, the trough can be arranged at right angles to the direction of throwing.
