description: Subject matter of the graduate qualification work: Â«Numerical modeling of furnace process in the boiler E-420-140-560 during lignite combustionÂ».The work is devoted to numerical modeling of the furnace process for combustion of lignite Chernovsky to ensure safe, economic operation of the boiler with minimal emissions of nitrogen oxides, by changing various parameters of burner devices, their vane swirlers and layouts.The paper describes the structure and equipment of the boiler unit, substantiates the choice of slag removal system and dust preparation system, calculates the volumes and enthalpy of air and combustion products, by which the thermal balance and the furnace chamber of the boiler are calculated for further use in the software package.Data for the software package SigmaFlame, to create a three-dimensional model of the furnace chamber in the software package with the imposition of the calculation grid and the burner window with setting of all necessary properties, were prepared and the calculationFour design variants were developed in the work, the analysis was made for each of them. On this basis, the best layout, and parameters of burner devices for the existing furnace geometry were selected.
