Description
Verfahren zur Verheizung entgaster Brennstoffe o. dgl. auf Wanderrosten. Bei mechanischen Feuerungen, bei welchen der Brennstoff an einem Ende in die Feuerung eintritt und die Asche am anderen Ende ausgetragen wird, hängt die Entzündung des eintretenden Brennstoffes von der strahlenden Hitze der Flammen oder des Mauerwerks ab, oder von der Berührung mit brennendem Brennstofft. Bei vielen Brennstoffen, besonders entgasten, wie Koks, tritt die von diesen Wärmequellen abhängende Entzündung zu langsam ein oder versagt zuweilen vollständig.Process for heating degassed fuels or the like on traveling grates. In the case of mechanical furnaces, in which the fuel is fed into the furnace at one end enters and the ashes are discharged at the other end, the inflammation depends on the entering fuel from the radiant heat of the flames or the masonry or from contact with burning fuel. With many fuels, especially degassed, like coke, occurs the ignition dependent on these heat sources on too slowly or at times fails completely.
Gemäß der Erfindung wird die Entzündung des Brennstoffes dadurch unterstützt, daß ein Teil der heißen Verbrennungsprodukte gegen das vordere Ende der Rostfläche über den eintretenden Brennstoff hin geleitet wird.According to the invention, the ignition of the fuel is supported by that part of the hot combustion products against the front end of the grate surface is passed over the entering fuel.
Zu diesem Zwecke ist über dem mechanischen Rost das übliche Zündgewölbe eingebaut, das den Vorderteil des Rostes überdeckt. In dem Zündgewölbe sind eine oder mehrere Öffnungen in der Nähe des Fülltrichters angebracht, welche die Kanäle führen und den Verbrennungsgasen den Durchtritt nach der Verbrennungskammer oder zu einem Zuge gestatten.For this purpose, the usual ignition vault is above the mechanical grate built in, which covers the front part of the grate. In the ignition vault are one or several openings near the hopper, which open the channels lead and the combustion gases pass through to the combustion chamber or to allow one move.
Die Verbrennungsprodukte des unter dem Gewölbe brennenden Brennstoffes werden durch die beschriebenen Hilfsmittel geteilt, so daß ein Teil nach der Vorderseite der Feuerung über den eintretenden Brennstoff hinstreicht.The combustion products of the fuel burning under the vault are divided by the means described, so that a part after the front the furnace over the incoming fuel.
Eine Feuerung dieser Art ist in der Zeichnung dargestellt, und zwar im senkrechten Schnitt durch einen Wanderrost bekannter Bauart. Das, Zündgewölbe a ragt in den Verbrennungsaum b hinein. Am vorderen Ende des Gewölbes ist eine Öffnung c angebracht, welche als Zug d durch das Gewölbe fortgesetzt ist. Die Pfeile zeigen an, daß, während die große Masse der Verbrennungsgase sich nach hinten über den Rost zur Verbrennungskammer b bewegt, ein Teil durch die Öffnung cund den Zug d abgezogen wird. Dieser Teil dient dazu, den Brennstoff beim Eintreten in die Feuerung aus dem Trichtere zu erhitzen.A furnace of this type is shown in the drawing, namely in a vertical section through a traveling grate of known type. That, ignition vault a protrudes into the combustion chamber b. There is an opening at the front end of the vault c attached, which is continued as train d through the vault. The arrows show suppose that while the great bulk of the combustion gases spread backwards over the Grate moved to combustion chamber b, part through opening c and train d is deducted. This part serves to keep the fuel from entering the furnace from the funnel to heat.
Wo verstärkter Zug angewandt wird, hat die Einrichtung den weiteren Vorteil, daß die Öffnung .oder die Öffnungen im vorderen Teil des Gewölbes einen freieren Austritt der Verbrennungsprodukte ermöglichen, so daß das Entweichen von Gasen in den Raum am oder nahe am Fülltrichter vermieden wird.Where increased pull is applied, the facility has the further Advantage that the opening. Or the openings in the front part of the vault a Allow more free exit of the combustion products, so that the escape of Gases in the space at or near the filling funnel is avoided.
