Evaluation of the Coking Capacity Indicator of Coking Coal Concentrates Based on the Research of Non-volatile Residue Strength Via Determination of the Coking Chemical Products Yield

Abstract

In modern conditions, one of the most acute problems for the coking industry include deterioration of raw material base for coking and coking coal deficit. The negative impact of the deterioration of the raw material condition on the yield and quality of coking products can be compensated by the increase in the level of coal blending quality management, which is primarily based on the chemical and technological properties of coal. Therefore, for the analysis of the above parameters, it is necessary to make a full use of the potential of all available coal properties valuation techniques. In the course of this work, the quality indicators of coal concentrates of the Kuznetsk Basin were defined and the strength properties of non-volatile residue obtained in determining the yield of chemical products of coking were studied. Based on the analysis of the obtained results, the experimental dependences of the reviewed parameters were built. Keywordscoal, volatile matters, chemical products of coking, non-volatile residue, non-volatile residue strength.
