Description

Verfahren zur Verkohlung von Holz. Die Erfindung stellt sich die Aufgabe, die Hclzverkohlung in der Weise durchzuführen, daß eine dichte und harte Holzkohle erhalten wird, die für die Verwendung im Hüttenbetriebe besonders geeignet ist. Sme besteht im wesentlichen darin, daß Holzverkohlungsöfen aller Art mit Holz beschickt werden, das mit den bei der Verkohlung erhaltenen, mit Teerdämpfen beladenen Destillationsprodukten durchtränkt wurde, so daß die in den Poren des Holzes vorhandenen _P.echartig-en Produkte bei der Erhitzung, unter Abscheidung von Kohlenstoff, zersetzt werden. Macht es der Ofen möglich, die Beschickung lange Zeit kühl zu halten, so wird das Niederschlagen der Dämpfe auf der Beschickung im Ofen selbst durchgeführt; in anderen Fällen werden die Dämpfe auf dem Verkohlungsofen abgezogen und auf außerhalb des Ofens untergebrachtem Holz kondensiert.Process for charring wood. The invention has the task of Carry out the charring in such a way that a dense and hard charcoal is obtained, which is particularly suitable for use in the metallurgical industry. Sme consists essentially in that charring furnaces of all kinds are charged with wood that with the tar vapors laden distillation products obtained during the charring was soaked so that the _P.echartig-en present in the pores of the wood Products decompose when heated, with the deposition of carbon. If the oven makes it possible to keep the load cool for a long time, it will Deposition of vapors on the loading carried out in the furnace itself; in other Cases, the fumes are drawn off on the charring furnace and transferred to outside of the The wood in the stove condenses.

Ein Niederschlagen von Teerdämpfen auf der Beschickung findet auch bei bekannten Verkohlungsapparaten für periodischen Betrieb statt. Die Menge ist aber so geringfügig, daß sie auf die Beschaffenheit des Produktes ohne Einfluß bleibt. Ein Durchtränken des Holzes mit Teer ist im ununterbrochenen Verkohlungsbetrieb nur bei solcher Durchführung des Prozesses erzielbar, daß eine entsprechend hohe Zone von Holz lange Zeit auf niedriger Temperatur verbleibt.There is also a deposition of tar fumes on the feed in known charring apparatus for periodic operation instead. The crowd is but so insignificant that it has no effect on the nature of the product. Soaking the wood with tar is in continuous charring operation can only be achieved if the process is carried out in such a way that a correspondingly high Zone of wood remains at a low temperature for a long time.

Holzkohle, die nach dem beschriebenen Verfahren erzeugt wird, besitzt eine so dichte und harte Beschaffenheit, wie sie nachkennem der bisher bekannt gewordenen Verfahren erreicht werden kann. Da der Verkaufswert solcher Holzkohle infolge ihrer Verwendbarkeit im Hüttenbetriebe hoch ist, wird der Verlust, der durch die Verringerung der erzeugten Nebenprodukte veranlaßt wird, bei weitem wettgemacht Die Wärmeökonomie des Verfahrens ist dabei günstiger als jene bei vollständiger Wiedergewinnung der Nebenprodukte, weil die gesamte Wärme der Dämpfe vom frischen Holz aufgenommen wird.Charcoal, which is produced according to the method described, has a texture as dense and hard as you know from the one that has hitherto become known Procedure can be achieved. Since the sales value of such charcoal as a result of their Availability in the metallurgical plant is high, the loss caused by the reduction of the by-products produced is caused by far offsetting the heat economy the process is more favorable than that with complete recovery of the By-products because all of the heat from the vapors is absorbed by the fresh wood.
