In optimization of a utility boiler furnace operation, special attention is given to the flame geometry and position. As an illustration of possibilities for application of mathematical prediction and numerical experiment in efficient optimization of the flame, the paper presents selected results of simulations of processes in pulverized coal tangentially fired furnace of Kostolac-B 350 MW electric boiler unit. To analyze the furnace working under different conditions, a differential 3D mathematical model of two-phase turbulent reactive flow with heat and mass transfer and corresponding computer code have been developed. Using the model and the code, previously carefully verified and validated against field measurements, an extensive numerical study has been performed to investigate the dependence of the furnace flame characteristics on different operating conditions, including distribution of the coal, air flow rates, and particle size classes over the burner tiers, as well as the quality and grinding fineness of coal and the operation scheme of the coal mills. The numerical predictions of the flame characteristics enable a specific tool for optimization of the boiler unit with respect to efficiency and ecology. 6 Energy & fuels 23 ARTICULO Belosevic, Srdjan 42236 Sijercic, Miroslav 42237 Crnomarkovic, Nenad 42238 170770 170770 0 0 0 0 238589 BAAB BAAB 2026-03-05 200045624 0 200045624 2026-03-05 15:12:56 2026-03-05 ARTICULO
