Abstract

The invention relates to a process for the manufacture of coke from coal by coking the coal and, if appropriate, one or more further process stages such as drying and preheating of the coal upstream of coking and, if appropriate, dry coke cooling downstream of coking, the coking and, if appropriate, one or more of the further process stages being carried out in a vessel sealed pressure-tight in each case by means of a gas which can be passed through the vessel by direct and/or indirect heat exchange, according to Patent Application P 3,516,227.9-24. It is proposed that the coal for the coking (formation of lumpy coke) is heated in the vessel only by indirect heating in the temperature range between about 250 DEG C and 600 DEG C. The distance of the heat sources and the temperature of the heat sources is matched to the desired lump size and quality of the coke.

Description

Die Erfindung betrifft ein Verfahren zur Erzeugung von Koks aus Kohle durch Verkokung der Kohle und gegebenenfalls eine oder mehrere weitere Verfahrensstufen wie eine der Verkokung vorgeschaltete Trocknung und Vorerhitzung der Kohle sowie gegebenenfalls eine der Verkokung nachgeschaltete trockene Kokskühlung, wobei die Verkokung und gegebenenfalls eine oder mehrere der weiteren Verfahrensstufen in einem druckdicht geschlossenen Gefäß mittels jeweils eines durch das Gefäß hindurchleitbaren Gases durch direkten und/oder indirekten Wärmeaustausch ausgeführt wird bzw. werden, nach der Patentanmeldung P 35 16 227.9-24.The invention relates to a process for producing coke from coal Coking the coal and possibly one or more others Process stages such as drying prior to coking and Preheating the coal and possibly one of the coking downstream dry coke cooling, the coking and optionally one or more of the further process stages in one pressure-tightly closed vessel by means of one through the vessel conductive gas through direct and / or indirect heat exchange is or are carried out according to patent application P 35 16 227.9-24.

Die Aufgabe der vorliegenden Zusatzerfindung besteht darin, den früheren Erfindungsvorschlag dahingehend weiterzubilden, daß der gleichmäßige Verkokungsablauf auch bei ungünstigen Kohlequalitäten zu einer ausreichenden Stückkoksbildung führt.The task of the present additional invention is to replace the earlier one Propose invention proposal that the uniform Coking process into one even with unfavorable coal qualities sufficient coke formation leads.

Es wurde gefunden, daß bei einigen Kohlequalitäten die Koksbildung im Temperaturbereich zwischen 350°C und 600°C stattfindet, in der infolge der plastischen Phase mangels gleichmäßigem Gasdurchgang bei direkter Beheizung der Kohleschüttung im Gefäß auch der Verkokungsablauf gestört wird. It has been found that coke formation in some coal grades in Temperature range between 350 ° C and 600 ° C takes place in the consequence the plastic phase due to lack of even gas passage with direct Heating the bed of coal in the vessel also disrupted the coking process becomes.  

Zur Lösung dieses Problems wird vorgeschlagen, daß die Kohle für das Verkoken (Stückkoksbildung) in dem Gefäß mindestens im Temperaturbereich zwischen etwa 250°C und 600°C nur durch indirekte Beheizung aufgeheizt wird, wobei der Abstand zwischen den Wärmequellen der gewünschten Stückgröße des Kokses angepaßt sein soll und die Temperatur der Wärmequellen zur Erreichung einer optimalen Koksqualität regulierbar ist.To solve this problem, it is proposed that the coal for the Coking (piece coke formation) in the vessel at least in the temperature range between about 250 ° C and 600 ° C only heated by indirect heating , the distance between the heat sources of the desired Piece size of the coke should be adjusted and the temperature of the Heat sources to achieve optimal coke quality is adjustable.

Bei Einhaltung dieser Bedingung ist mit allen Kokskohlequalitäten eine optimale Stückkoksqualität erreichbar.If this condition is complied with, all coking coal grades have one optimal piece coke quality achievable.
