Description	Journal: Journal of Physics: Conference Series Purpose of the study is to obtain fundamental knowledge about Kuznetsk bituminous coal entrained-flow gasification in $O_{2}-CO_{2}$ mixtures for oxy-fuel IGCC. To achieve this purpose, it is necessary to carry out experimental and numerical studies. To obtain universal knowledge, "CKTI" single-stage gasifier with fuel consumption of 5-15 kg/h was chosen as an experimental installation. In order to identify the most interesting and informative experimental regimes, a number of computational studies have been carried out, whose results are given in the paper. A numerical (CFD) model has been developed, which includes all the submodels necessary for the study. Two series of numerical calculations were carried out. In the first series, the composition of the blast $(O_{2}$ = 0-100%, $CO_{2}$ = 0-100%) and the oxygen ratio were varied at constant consumption of coal and blast. In the second series, the composition of the blast $(O_{2}$ = 0-100%, $CO_{2}$ = 0-100%) and the coal consumption were varied at constant oxygen ratio and blast flow rate. The study allowed predicting and analyzing the temperature distribution and the syngas components content along the gasifier height with different $CO_{2}$ concentrations in the blast.
