Summary:The mathematical statement of the problem on gasification of coal dust particles in the blast-furnace tuyere apparatus is given, which includes the motion equation of a variable mass particle, heat equation of a particle and the heat-balance equation of the blast flow. The results of calculations are obtained by using mathematical software packages (Mathcad, Maple). Relatively weak effect of the volatiles combustion process on the thermal state of the tuyere zone is shown.
