Abstract
The use of an empirical equation to calculate the vitrinite reflectance of coal from the fuel ratio Fr is considered. The fuel ratio is based on the fixed coal content (Cfixed = 100 – Ad – Vd) and the yield of volatiles (Vd). We investigate ten samples of bituminous coking coal (Zh coal) used as the clinkering component in the coking batch. Technical and elemental analysis indicates that the ash content of the samples is <10% and the yield of volatiles is 33.2–37.7%. Petrographic analysis shows that the vitrinite reflectance Ro,r = 0.825–0.982%, while the content of vitrinized components is 78–90%. The experimental data confirm that the relation between Ro,r and Fr may be used with high accuracy to calculate the vitrinite reflectance. Hence, the proposed method may be recommended to calculate the vitrinite reflectance for coal in the clinkering component of the coking batch.
