description: Subject of the graduate qualification work: "Numerical modeling of furnace process in the boiler E-540-140-560".The paper compares the level of nitrogen oxide emissions of different configurations of burner devices in the boiler E-540-140-560, working on urgalsky hard coal, using the program SigmaFlame. The description of the boiler unit with the choice of dust preparation system and bottom ash removal method is presented. The burner devices have been calculated, the data for numerical simulation of the furnace chamber have been prepared. The geometry of the furnace chamber was built based on the data obtained from the thermal calculations performed in accordance with the regulatory method. Numerical simulations for three configurations of burner devices are performed and each of the options is analyzed. As a result of the work, the configuration of burners with the best economic and environmental characteristics was selected.
