Abstract
In coal coking, volatile products are liberated. As a result, deposits of pyrocarbon (graphite) are formed on the walls and roof of the coke ovens. Those deposits may obstruct the extraction of coke cake. By identifying the parameters with the greatest effect on the formation of pyrocarbon, its growth in the coke ovens may be more accurately monitored, and hence the coke plant’s stock of coke ovens may be better maintained. The influence of the following factors on the rate of pyrocarbon formation is investigated: the metamorphic development of the coal; its moisture content; and its granulometric composition.
