Modelling of the High-Speed Thermal Decomposition of Irkutsk Basin Coals
A.S. Safarov, A.A. Levin, A.N. Kozlov, V.G. Galeev, Yusuf IsaThe study focuses on the development of a mathematical model for high-speed temperature-induced decomposition of coals under uncertainty in the closure relations describing the thermophysical properties and kinetics of fuel particle decomposition. Kinetics of chemical reactions in coal particles in a plasticization unit are determined by solving a mathematical programming problem. Closure relations for thermal conductivity and density are proposed in the form of functional dependencies on fuel temperature, reflecting endothermic and exothermic reactions. Fuel samples from the Cheremkhovsky and Azeysky deposits (Irkutsk Coal Basin) and Zheronsky coal (Tunguska Coal Basin) were used.
