Abstract
The influence of ash content on the chemical composition of the ash is considered, along with the dependence of the Fe2O3, CaO, MgO, and SiO2 content in the ash of Kuznetsk and Donetsk coal on the yield of volatiles V daf, which characterizes the degree of metamorphism. Correlation analysis shows that this dependence is described by second-order polynomial equations within the ranges considered. Within the interval V daf= 20–28% (from the overall range 8 ≤ V daf ≤ 45% considered), the content of most oxides in the ash passes through an extremum. The idea that high contents of ore components (Fe2O3, CaO, and MgO) in the ash are useful should be revised, since they impair the CSR and CRI values of the coke.
