摘要：
A model, describing nonstationary heat- and mass exchange processes in the boundary gas volume around a pyrolytic coal particle in a hot gaseous medium, is proposed. A method for solving numerically nonstationary equations of conservation of mass, chemical components and energy of the gaseous medium, having boundary conditions, reflecting the burning coal particle behaviour, is developed. New effects under thermal conditions of ignition and burning of pulverized coal particles are revealed.
