Аннотация: Have been based on the Euler/Lagrange approach for turbulent reacting gas-particle flows with combusting pulverized coal particles, a comprehensive model for pulverized coal combustion has been developed by incorporating a model of pulverized coal devolatilization and char combustion, a model of NOx formation and a model of ash depПоказать полностьюosition. Applicability of the comprehensive model has been validated by comparing its predictions with the experimental data. The mathematical model has been applied to a 800-MW tangentially-fired boiler of the Berezovskaya Power Plant to evaluate aerodynamics, heat exchange, formation of nitrogen oxides, and the intensity of local slag formation for different operation regimes and variants of the reconstruction of the furnace-burner device. Numerical data have been used to reconstruction the furnace of the P-67 boiler. The predicted results from the mathematical model are in good agreement with the experimental measurements after reconstruction the furnace.
