Description
Kupolofen mit Kohlenstaubfeuerung. Die Erfindung bezieht sich auf einen Kupolofen mit Kohlenstaubfeuerung. Sie besteht darin, daß die in der vorgelagerten Staubverbrennungskammer entwickelten Heizgase über einen zwischen der Verbrennungskammer und dem anschließenden Füllschacht angeordneten Herd streichen, in welchen das im unteren Teil des Schachtes schmelzende Metall über eine das Schmelzgut im Herd überragende Rast abläuft. An dieser Stelle wirkt die gröMte Wärme auf das Eisen ein, das hier in reiner Form, auch für den Guß schwerer Stücke bei verhältnismäßig kleinem Ofen, entnommen werden kann.Cupola furnace with pulverized coal firing. The invention relates to a cupola furnace with pulverized coal firing. It consists in that in the upstream Dust combustion chamber evolved heating gases through an intermediate combustion chamber and the adjoining hopper arranged hearth, in which the im lower part of the shaft melting metal above the melting material in the hearth Rast expires. This is where the greatest heat acts on the iron, this one in pure form, also for casting heavy pieces in a relatively small furnace, can be taken.
Vorteilhaft wird die Staubverbrennungskammer senkrecht angeordnet und das Staubluftgemisch in die Kammer senkrecht von oben eingeführt. Die unverbrennbaren Schlackenteile des Kohlenstaubes sammeln sich dann in flüssigem Zustande am Boden der Kammer an und können von dort abgezogen werden, so daß erst recht keine Verunreinigung des Eisens und keine Veränderung der Beschickung durch den Angriff der Kohlenschlacke herbeigeführt wird.The dust combustion chamber is advantageously arranged vertically and the dust air mixture introduced into the chamber vertically from above. The incombustible ones Slag parts of the coal dust then collect in a liquid state on the bottom the chamber and can be withdrawn from there, so that no contamination of iron and no change in the charge due to the attack of the coal slag is brought about.
In der Zeichnung ist ein derartiger Ofen in einem senkrechten Querschnitt dargestellt. ca ist die Staubverbrennungskammer, durch deren Decke mittels eines Düsenrohres b das Staubluftgemisch senkrecht von oben eingeblasen wird. Die unverbrennbaren Schlackenteile der Kohle werden in flüssigem Zustande unten in der Kammer abgeschieden und aus einem Sumpfe c mit geneigter Sohle nach außen abgezogen.In the drawing, such a furnace is in a vertical cross-section shown. ca is the dust combustion chamber, through the ceiling of which a Nozzle tube b blown in the dust air mixture vertically from above will. The incombustible slag parts of the coal are in a liquid state below deposited in the chamber and from a swamp c with an inclined sole to the outside deducted.
An die Verbrennungskammer a schließt sich der Herdschmelzofen d mit vertiefter Sohle und an diesen der .senkrechte Schacht e an. Den Übergang vom Herde zum Schacht bildet die Rast f, auf welche sich die Säule der in dem Schacht ruhenden Eisenstücke aufsetzt und über die das abschmelzende Metall in den Herd läuft.The hearth furnace d is connected to the combustion chamber a recessed sole and to this the vertical shaft e. The transition from the herd to the shaft forms the latch f, on which the column of the resting in the shaft Pieces of iron and over which the melting metal runs into the stove.
