Rank assignment of coal in terms of its clinkering and coking properties

Аннотация

Comparison of the clinkering and coking properties of coal from different basins indicates that the rank boundaries adopted in State Standard GOST 25543–2013 in terms of the plastic-layer thickness do not correspond to the boundaries in terms of the coking properties. The coal samples are arranged in order in terms of the coking capacity K^cc and the coke-forming capacity K^cfc, and a classification of coal ranks on the basis of the coking properties is proposed.
