KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Feuerungen, welche mit Kohlenstaub verschiedener Gröfse von oben oder oben seitwärts beschickt werden, fallen gröbere Staubtheilchen als feiner Koks zu Boden und können dann wegen Mangels an Luft nicht vollständig ausbrennen; sie lagern sich z. B. bei Dampf-„kesselbetrieben in den Feuerzügen ab und werden mit der Flugasche entfernt.In the case of furnaces with coal dust of various sizes from above or sideways from above are charged, coarser dust particles fall to the ground than fine coke and can then do not burn out completely due to lack of air; they store z. B. in steam "boiler operations in the fire flues and are removed with the fly ash.
Diesem Uebelstande soll durch das Verfahren, den Kohlenstaub von unten in einen sich nach oben erweiternden Verbrennungsraum einzublasen, abgeholfen werden.This inconvenience is to be followed by the process, the coal dust from below into one itself To blow in the combustion chamber widening at the top, can be remedied.
Der hierzu erforderliche Verbrennungsofen hat einen von feuerfestem Stoff umgebenen, nach oben sich trichterförmig erweiternden Verbrennungsraum C, in welchen das Kohlenstaubluftgemisch von unten oder unten seitwärts einströmt.The incinerator required for this has a refractory material, combustion chamber C widening in the shape of a funnel to the top, in which the pulverized coal air mixture from below or from below sideways flows in.
..Die Isolirschichten i können als Zuführungskanal benutzt werden und dient dabei die von innen ausstrahlende Wärme zur Vorwärmung des Kohlenstaubluftgemisches und zur leichteren Entzündbarkeit desselben. Die Erweiterung nach oben hat den Zweck, die Luft- bezw. Gasstromgeschwindigkeit so zu vermindern, dafs etwa aus dem Verbrennungsbereich hochgetriebene, noch nicht vollständig verbrannte gröbere Kokstheilchen immer wieder zurückfallen und nicht in die Feuerzüge hinübergerissen werden...The insulating layers i can be used as a supply channel and the heat radiating from the inside serves to preheat the pulverized coal air mixture and to make it easier to ignite. The purpose of the upward expansion is to reduce the air or To reduce the gas flow velocity so that, for example, coarser coke particles that have not been completely burned up from the combustion area fall back again and again and are not carried over into the flues.
Nur die all erleichteste Flugasche wird weiter getragen. Der gröfste Theil schmilzt bei den hohen Temperaturen im Verbrennungsraum und läuft in den Schlackenabstich S unter den Einblasedüsen zusammen, wo er leicht als flüssige Schlacke abgeführt werden kann, ohne dafs der Betrieb dadurch unterbrochen werden müfste.Only the easiest fly ash is carried on. The greater part melts at the high temperatures in the combustion chamber and converges in the slag tap S under the injection nozzles, where it can easily be discharged as liquid slag without the operation having to be interrupted.
