The calculated investigation of thermochemical conversion reactor are carried out by Thermoflow software package. The influence quality estimation on the synthesis gas composition of the process parameters: the type and composition fuel, the gasifying agent (air, steam, oxygen-steam), temperature and fuel / oxidizer, the conversion degree and heat losses. Estimation on the equilibrium composition of produced synthesis gas are conducted. The paper describes a numerical simulation of the vortex gasification apparatus of solid fuels with low capacity. The internal configuration optimization of the oxidation and reduction section in the aggregate as well as oxidizing medium supplying to the first and second stages are performed by ANSYS CFX. The thermochemical conversion of Ekibastuz coal particles in air and steam-air blow by TGA method is simulated. The kinetic characteristics of the initial fuel and its coke residue in diferent modes, which modeling a two-zone setup, are obtained.
