Аннотация: The basic combustion characteristics and kinetic parameters of Chernogorsk coal are determined before and after carbonization. The method employed is thermal analysis in an oxidative atmosphere with fuel heating at 20°C/min. The following characteristics of fuel combustion are determined from the curves of mass loss, rate of mass variation, and differential scanning calorimetry: the ignition temperature; the combustion temperature; the maximum reaction rate and the corresponding temperature; and endothermal and exothermal effects. By the Coats–Redfern method, the basic kinetic parameters of the coal before and after carbonization are determined. By electron microscopy, the surface of the fuel particles is qualitatively assessed. The results may be used in the design of thermal and energy equipment. Coal carbonization increases the ignition temperature by 3% and the combustion temperature by 17%. The maximum reaction rate is decreased. The activation energy and preexponential factor are lower after carbonization. © 2022, Allerton Press, Inc.
