Numerical simulations have been conducted to study combustion characteristics of tangentially fired pulverized-coal boiler. A 600 MW tangentially coal-fired boiler was used for investigating the effect of platen super-heaters on the temperature, species distributions and heat transfer. Two furnace models were established, whose difference lies in modeling super-heaters or not. Results show that modelling platen super-heaters is conducive to precisely predict the temperature, species (CO, CO2, O2) and heat flux in the platen zone and has a weak influence on these data in zones below the platen. Modelling platen super-heaters has little influence on the NOx prediction. Platen super-heaters obviously decrease heat absorbed by water-wall nearby and affects heat distribution coefficient of furnace.
