Abstract

The ignitability of powdered coal is increased by (a) applying a film of a liq. alcohol by dipping, spraying, etc.; or (b) mixing with a powdered solid alcohol. The ignitability of mixts. of coal with oil residues, recovered oil, oil shale and the like can be improved by adding a greater concn. of alcohol. Used for improving the usually difficult combustion of anthracite and other low-volatile coals in a pulverised coal burner.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Verfahren zur Verbesserung der Brandfähigkeit von Kohlestaub, der zündträge ist.' Es ist bekannt, daß insbesondere Anthrazitkohle bzw. grundsätzlich Kohle, die wenige Flüchtige hat, sich schwierig durch Kohlestaubbrenner verfeuern läßt.'' Method of improving the combustibility of coal dust, the ignition is. ' It is known that in particular anthracite coal or in principle Coal that has few fugitives is difficult to burn through pulverized coal burners leaves.

Um diese Schwierigkeiten zu vermeiden, wird erfindungsgemäß vorgeschlagen, den Kohlestaub mit einem Alkoholfilm zu versehen.In order to avoid these difficulties, it is proposed according to the invention that to provide the coal dust with an alcohol film.

Dieses kann durch Tauchen, Ansprühen oder dergleichen vorgenommen werden.This can be done by dipping, spraying or the like will.

Äquivalent dazu kann natürlich auch (und/oder) fester Alkohol in feiner Puderform der eigentlichen Kohlestaubmischung zugegegeben werden.Equivalent to this can of course also (and / or) solid alcohol in fine Powder form of the actual coal dust mixture can be added.

Versuche entsprechend diesem erfindungsgemäßen Gedanken haben gezeigt, daß es keine Schwierigkeiten gibt, selbst den schwierigsten Kohlestaub mit dieser Zündhilfe zu verbrennen.Tests according to this inventive idea have shown that there is no trouble, even the most difficult coal dust with this one Burn ignition aid.

Soll die Kohle mit anderen Stoffen, z. B. Stoffenölhaltiger Struktur, zusammengebracht werden, so ist es durchaus möglich, den Alkoholzusatz, insbesondere den flüssigen Alkoholanteil, zu vergrößern und dadurch in einer pumpfähigen Suspension die Kohlestaubanteile in einer Konsistenz im Schwebezustand zu halten.If the coal is to be mixed with other substances, e.g. B. Oil-containing structure, be brought together, so it is entirely possible to add alcohol, in particular the liquid alcohol content, to increase and thereby in a pumpable suspension to keep the coal dust in a consistency in suspension.

Selbstverständlich können mit dem Alkohol außer Kohle auch Ölschiefer, Ölrückstände, Altöle usw. gemischt werden, die zündfreudig gestaltet werden.Of course, in addition to coal, oil shale, Oil residues, used oils, etc. are mixed, which are designed to be easily ignitable.
