Forecast of the gross calorific value of coking coals

Resumo

The comprehensive analysis of 63 test samples of coal concentrates from Ukraine, the Russian Federation, and countries outside the former Soviet Union (the United States, Canada, Australia, and Poland), which constitute the current raw materials base of the by-product coke plants of Ukraine, was carried out. Mathematical equations for the forecast of gross heating values on a dry, ash-free basis were developed separately for the coals of Ukraine, the Russian Federation, and the countries outside the former Soviet Union with consideration for differences in the petrographic compositions and the degrees of reduction of coals from different basins. The correctness of forecast ensured by the developed equations was within the limits of permitted standard deviations.
