COMPACTING BRIQUETTES OF COAL FOR COKE OVEN FEED

摘要

The process for producing coke, in particular furnace coke, uses considerable amounts of lean or relatively lean caking coal which is submitted to compaction so as to obtain pressed substances; these pressed substances are used on their own or mixed with additional material as charge in a coke furnace for the coking. The coal (A) is submitted during compaction to forces acting upon different directions (D, T) in order to create shearing and/or rotating stress. This causes the mutual fixing of the coal particles thus giving highly resistant pressed material with a high degree of conservation. During compaction, heat can be brought to the material. A device for application of this process comprises a matrix and an element which makes the material pass through the channels of the matrix. These channels have different diameters and can also have different lengths.
