Description

Verfahren zum Betrieb von Wanderrostfeuerungen. Bei Wanderrostfeuerungen mit Unterwind ergibt sich der Nachteil, daß am Ende des Rostes Luftüberschuß herrscht. Der mit seiner Unterlage gleichmäßig vorgeschobene Brennstoff ist nämlich an dieser Stelle durch Ausbrennen stark gelockert, so daß die Luft leicht hindurchdringt und außerdem nicht mehr genügend Brennbares zu ihrer Aufzehrung vorfindet.Procedure for the operation of traveling grate furnaces. With traveling grate firing with a downwind there is the disadvantage that there is excess air at the end of the grate. The evenly advanced fuel with its base is namely on this The place is loosened by burning out so that the air can easily penetrate and also no longer finds enough combustibles to consume.

Die hierdurch entstehenden Abgasverluste werden der Erfindung gemäß dadurch verhütet, daß aus den vom Rost abfallenden glühenden Rückständen hinter dem Rost durch Vergasung brennbares Gas erzeugt und dieses durch Zurückführung mit der über dem Rostende vorhandenen überschüssigen Luft vermischt wird. Die überschüssige Luft wird hierdurch vollständig aufgezehrt, wodurch Abgasverluste vermieden werden. Aber auch die Aschfallverluste «-erden auf ein denkbar geringstes Maß beschränkt, da gleichzeitig aus dem Brennstoff in ergiebigster Weise das Brennbare herausgeholt wird. Die Vergasung muß sich natürlich dem Betrieb des Wanderrostes anpassen.The resulting exhaust gas losses are according to the invention this prevents the glowing residues falling off the grate from being left behind the grate generates combustible gas through gasification and this through recirculation the excess air present above the end of the grate is mixed. The excess Air is completely consumed as a result, which prevents exhaust gas losses. But also the ash fall losses "are limited to the lowest possible level, because at the same time the combustible material is extracted from the fuel in the most productive way will. The gasification must of course adapt to the operation of the traveling grate.
