Description

Wanderrost mit Unterwind. Die Erfindung betrifft einen Wanderrost mit Unterwind, bei dem die infolge des Unterwindbetriebes in den Heizraum tretenden Schwelgase abgesaugt werden. Der Rost ist dabei vorn ohne weiteres zugänglich, so daß die Rostbahn überwacht werden kann. Dies erfolgt gemäß 'der Erfindung dadurch, daß an dem die Schichthöhe regelnden Schieber ein Hohlraum vorgesehen ist, der an den Saugstutzen eines Ventilators oder an einen Schornstein. o. dgl. angeschlossen ist. Der in dem Hohlraum herrschende Unterdruck übt dabei vor und auch oberhalb und seitlich von denn Schieber seine absaugende Wirkung aus. Durch diese Anordnung wird noch der weitere Vorteil erzielt, daß auch ein Heraustreten von Schwelgasen usw. in der Umgebung des Schiebers verhindert wird. In dee= Zeichnung ist der Gegenstand der Erfiüdung :in einem Ausführungsbeispiel in senkrechtem Längsschnitt dargestellt.Traveling grate with under wind. The invention relates to a traveling grate with underwind, in which the step into the boiler room as a result of underwind operation Smoldering gases are sucked off. The grate is easily accessible at the front, see above that the grate path can be monitored. According to the invention, this is done by that a cavity is provided on the slider regulating the layer height, which is connected to the suction nozzle of a fan or a chimney. or the like. Connected is. The negative pressure prevailing in the cavity exerts in front of and also above it and its suction effect from the side of the slide. Through this arrangement the further advantage is achieved that there is also an escape of carbonization gases etc. in the vicinity of the slide is prevented. In dee = drawing is the subject of the invention: in one embodiment in a vertical longitudinal section shown.

i ist Säer Verbrennungsraum, z der Brennstofftrichter, 3 :die obere Rostbahn, q. ein zwischen der oberen und der unteren Rostbahn angeordneter Dichtungskasten und 5 ein unterhalb der unteren Rostbahn angeordnetes Dichtungsblech, das die Abdichtung des hinteren Röstteiles nach vorm. hin, vollzieht. 6 ist ein 'die Schichthöhe regelnder Schieber. Zwischen diesem ;und der Rückwand des Trichters z ist ein Hohlraum 7 vorgesehen, der durch einen Kanal 8 mit 'dem. Saugstutzen eines Ventilators, reit -dem Schornstein oder mit einem Kesselzug verbunden ist. Der Hohlraue 7, ist derart ausgebildet, daß der in ihw. herrschende Unterdruck auch oberhalb des Schiebers 6 und seitlich von demselben seine absaugende Wirkung ausübt, ,so daß an dieser Stelle äus der Feuerung heraustretende Rauchgase sofort abgesaugt werden und daher nicht in den Heizraum übertreten können. Die absaugende Wirkung wird noch dadurch erhöht, daß am vorderen Rostende unterhalb der oberen Rostbahn ein Abdichtblech 9 vorgesehen ist, so daß nicht soviel Luft aus dem Heizraum in den Hohlraum übertreten kann.i is the sower combustion chamber, z the fuel hopper, 3: the upper one Rust track, q. a sealing box arranged between the upper and lower grate tracks and 5 a sealing plate which is arranged below the lower grate path and which forms the seal of the rear roasting part to the front. down, complete. 6 is a 'layer height regulator Slider. Between this; and the rear wall of the funnel z a cavity 7 is provided, through a channel 8 with 'the. Suction nozzle of a fan, rides the chimney or connected to a boiler train. The hollow bead 7 is designed in such a way that that the in ihw. The prevailing negative pressure also above the slide 6 and laterally exerts its suction effect from the same, so that at this point äus der Flue gases emerging from the furnace are sucked off immediately and therefore not in the Can step over the boiler room. The suction effect is increased by the fact that A sealing plate 9 is provided at the front end of the grate below the upper grate track so that not so much air can pass from the boiler room into the cavity.
