Аннотация
For 63 samples of Ukrainian, Russian, and imported coal, equations for predicting the gross calorific value Qsdaf on the basis of the following coal characteristics are developed: Wa, Oddaf, Qsaf, and Car. The error is within the standard tolerances (σ ≤ 0.3 MJ/kg). With sufficient accuracy, Qsdaf may be predicted from equations based on petrographic characteristics such as the vitrinite reflectance, the content of liptinitegroup minerals, and the sum of lean macerals (I + 2Sv/3). In these equations, the coefficients correspond to the heat of combustion of the vitrinite components at different metamorphic stages, the liptinite, and the lean macerals.
