Description
Feuerung mit quer im Feuerraum angeordneten, gegeneinander geneigten Vorschubrosten Die Erfindung betrifft eine Rostfeuerung mit in entgegengesetzter Richtung arbeitenden Vorschubrosten. Die neue Feuerung unterscheidet sich von den bekannten Feuerungen dieser Art dadurch, daß von je zwei derartigen Rosten der eine Rost höher als der andere angeordnet ist und ihn mit seinem unteren Ende überkragt. Hierdurch wird der Vorteil erzielt, daß der obere Rost übermäßig stark beschickt werden kann. Denn ein vollständiger Ausbrand braucht auf ihm nicht erzielt zu werden, @da sein Abfall auf dem unteren Vorschubrost zur vollständigen Ausbrennung gelangt. Weiterhin wird durch die teilweise Überlagerung der Roste erreicht, daß mehr Rostfläche untergebracht werden kann, als Grundfläche vorhanden ist. Außerdem werden die heißen Gase des unteren Teiles des Unterrostes, die Luftüberschuß enthalten, zwangsweise nach seinem oberen Teil geführt, so daß eine gute Durchmischung und Verbrennung der Gase erfolgt.Firing with transversely arranged in the combustion chamber, inclined towards each other Infeed grates The invention relates to a grate furnace with in the opposite direction Direction of working advancing grids. The new furnace differs from the known firings of this type in that of two such grates of one Grate is arranged higher than the other and protrudes over it with its lower end. This has the advantage that the upper grate is loaded excessively can be. Because a complete burnout does not need to be achieved on it, @ because his waste is completely burned out on the lower moving grate. Furthermore, the partial overlapping of the grids ensures that more grate surface is achieved can be accommodated, as a base is available. Besides, they'll be hot Gases of the lower part of the lower grate, which contain excess air, compulsorily led to its upper part, so that a good mixing and combustion the gases takes place.
Bei einer solchen Feuerung kann unter dem höheren Rost ein begehbarer Gang vorgesehen werden, der an sich bekannte Beobachtungsöffnungen zur Bewachung des unteren Teiles des tieferen Rostes besitzt und dessen Decke zweckmäßig als Kanal ausgebildet wird, durch welchen dem oberen Rost die nötige Verbrennungsluft über seine ganze Breite zugeführt wird. Bei Anordnung von mehreren Rosten werden diese vorteilhaft paarweise dachförmig zusammengesetzt. Dadurch, daß jeder Rost für sich angetrieben und mit Luft versorgt werden kann, läßt sich je nach der Beobachtung des Überwachenden Kohlenzufuhr, Rostbewegung und Luftzufuhr gesondert regeln.With such a furnace there can be a walk-in grate under the higher grate Aisle are provided, the per se known observation openings for guarding of the lower part of the deeper grate and its ceiling suitable as a channel is formed, through which the upper grate the necessary combustion air over its entire width is fed. If several grids are arranged, these advantageously assembled in pairs in a roof shape. In that each grate for itself can be driven and supplied with air, depending on the observation of the supervising person regulate the coal supply, the grate movement and the air supply separately.
In der Zeichnung ist eine solche Rostanlage für einen Großkessel von etwa 12 m Breite im senkrechten Schnitt, von der Vorderseite des Kessels aus gesehen, gezeigt.The drawing shows such a grate system for a large boiler from about 12 m wide in a vertical section, seen from the front of the boiler, shown.
In den Feuerraum sind Rostpaare getrennt voneinander eingebaut, von denen jedes aus einem unteren Rost ca und einem oberen Rost b besteht. Der obere Rost überkragt jeweils den unteren Rost, so daß der Abfall des oberen Rostes auf dem unteren Rost zum vollständigen Ausbrand gelangt. Unterhalb der oberen Roste befinden sich Gänge c, die mit verschließbaren Beobachtungsöffnungen ausgestattet sind, so daß man von hier aus den Ausbrand auf dem unteren Teil der Roste a und die Feuerführung auf diesen Rosten überwachen kann. Jeder Rost ist mit einem entsprechenden Kohlezuführungsschacht d' versehen, wobei die mittleren Roste aus dachförmig zusammengesetzten Teilen bestehen.Pairs of grates are built into the combustion chamber separately from each other, from each of which consists of a lower grate ca and an upper grate b. The upper Grate cantilevered over the lower grate, so that the waste of the upper grate on the lower grate is completely burned out. Below the upper grids there are corridors c, which are equipped with lockable observation openings are, so that from here you can see the burnout on the lower part of the grids a and can monitor the fire control on these grates. Each grate has a corresponding one Coal feed shaft d 'provided, the middle grids composed of roof-shaped Share exist.
Die Decken e der Beobachtungsgänge c sind hohl ausgebildet und dienen zur Zuführung der Druckluft für die über ihnen liegenden Roste b. Hierdurch werden gleichzeitig die Decken gut gekühlt und damit auch die Gänge c vor übermäßiger Erwärmung geschützt. Eine weitere Kühlung kann dadurch stattfinden, daß man Luft durch die Kanäle c hindurchbläst oder aber die zum Gebläse fließende Druckluft durch diese Kanäle hindurch ansaugt.The ceilings e of the observation passages c are hollow and serve for supplying the compressed air for the grids above them b. This will be at the same time the ceilings are well cooled and thus also the aisles c from excessive heating protected. Further cooling can take place by passing air through the Channels c blows through or the compressed air flowing to the fan through them Sucks channels through.
