A two-dimensional model of nonstationary steam–oxygen gasification of solid fuel in a fixed bed has been constructed, which took into account the interphase convective heat transfer, radiative-conductive heat transfer of the solid phase, radiative and conductive heat transfer of the bed with the reactor wall, heterogeneous and homogeneous chemical reactions, gravity force, and the aerodynamic drag force. The influence of the process parameters on the thermochemical treatment of the Shubarkol’ bituminous long-flame coal under a pressure of 3 MPa at ratios of the mass fractions of the steam–oxygen mixture components H2O/O2 = 45/55, 40/60, and 72/28 was studied.
