Thermolysis of Kansk-Achinsk Coals with Varied Extent of Oxidation and Combustion of Nonvolatile Thermolysis Products: A Study by Complex Thermal Analysis

Thermolysis of Berezovka coals with varied extent of oxidation and combustion of nonvolatile thermolysis products were studied by complex thermal analysis. The dynamics of thermochemical transforma- tion of the fuel in an inert medium was evaluated, with simultaneous determination of the kinetic parameters of evaporation of various kinds of moisture. The burn-out of nonvolatile thermolysis residues obtained from Berezovka coals at various pretreatment temperatures was studied, and a correlation was revealed between the kinetic parameters of combustion of nonvolatile residues and the extent of oxidation of the initial fuel.
