The goal of this work is to improve the efficiency of the solid low-reactive fuels use in thermal power plants. To achieve the goal we set the following tasks: to develop an equilibrium mathematical model that allows studying the gasification process of solid fuel in the steam-oxygen-air flow; analyze the influence of various mode factors on the composition of produced gas and the main indicators of the technological gasification process of coal particles in the flow, to determine the optimal values of mode factors. https://www.biotech-asia.org/vol12_nospl_edn2/equilibrium-models-of-the-gasification-process-of-solid-low-reactive-fuel-in-the-steam-oxygen-air-flow/ Coal gasification; Equilibrium mathematical model; Oxidant flow; steam-oxygen-air blast
