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
