description: Subject matter of the graduate qualification work: "Numerical modeling of furnace process in the boiler E-420-13,8-560 at hard coal combustion".This work is devoted to the numerical simulation of gas dynamics during the combustion of coke-yangak hard coal to ensure minimum nitrogen oxide emissions in the pulverized coal boiler E-420-13,8-560, by changing various parameters of burner devices and their layout.The paper describes in abstract the structure and equipment of the boiler unit, substantiates the choice of bottom ash 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 for further model building and calculations in the software package.A comparison of numerical simulation programs was made, from which the domestic SigmaFlame software package was selected. Data for building the model and conducting calculations in the software package were prepared.In the work 4 design variants were developed, for each of them the analysis was made. On the basis of the considered data the best layout and parameters of burner devices are selected.
