""Ü'6'r#steiilu-ng' vod ':'Zinkoxy'd' Zinc oxide is produced from the metal by burning it up, and it is technically today, in the way that the molten metal is in muffles The main part of the process is based on the necessary large furnace system and the very considerable wear and tear on muffles. It has now been shown that zinc oxide can be used in very small systems in a very economical manner can produce ', and., must have a percentage that gives an exceptionally high yield of the best zinc- # because #, _, t by adding', da # beforehand..fine --- powder-hot.Ziük-. Burns with oxygen or air as a flame: "in a similar way as is the case, for example, in a pulverized coal furnace. Once the ignition has been initiated, the zinc flame continues to burn, and it is sufficient to put the zinc oxide in chambers The combustion air is expediently, if not necessarily, heated beforehand, where appropriate, if necessary, it is also enriched with oxygen chert or replaced entirely by oxygen .

Es ist bereits vorgeschlagen worden, einen mit Metallstaub beladenen Luftstrom aus dem Innenrohr eines doppelwandigen Breriners austreten zu lassen. während gleichzeitig für die Dauer des ganzen Verfahrens aus der ririgfürmigpn Mündung. des Mantelrohrs ein -brennbares. Gas entströmt. welches den metallbeladenen. Luftstrom mit einer Flammenhülle umgibt. Beim Durchtritt durch diese Flaifimenhülle wird das Iletall genügend hoch erhitzt, um mit dem -vorhandenen Luftsauerstoff das gewünschte Oxyd zu bilden. Demgegenüber wird nach vorliegendem Verfahren auf eine'.derartige ständige Hilfsheizung verzichtet. vielmehr die für die Erhitzung, der i\Ietallteilchen notwendige '%Värme dem OxydatiOnsvorgange -selbst entnommen. Die hohe VerbrenntIngswärme des - Zinkmetalls, sein außerordentlich -niedri-er , . Si-d e epunkt und die Leichtflüchtigkeit seines Oxydes ermöglichen die Leitung der Verbrennung in Form einer sich selbst unterhaltenden Flamme, etwa nach Art einer Bunsen-Ramme.It has already been proposed to let an air stream laden with metal dust emerge from the inner tube of a double-walled Breriner. while at the same time for the duration of the whole procedure from the ririgfürmigpn estuary. of the jacket pipe a - flammable . Gas escapes. which the metal-laden. Surrounds the air stream with a flame envelope. When it passes through this bottle shell, the metal is heated to a high enough temperature to form the desired oxide with the oxygen present in the air. In contrast, according to the present method, such a permanent auxiliary heating is dispensed with. rather, the% heat necessary for heating the metal particles is taken from the oxidation process itself. The high VerbrenntIngswärme of - zinc metal, be extremely -niedri-er. Si-d e e point and the volatility of its oxide enable the combustion to be conducted in the form of a self-sustaining flame, for example in the manner of a Bunsen ram.
