Abstract
A comprehensive numerical and experimental study on a 200Â MW tangentially fired boiler firing metallurgical gases was conducted. A three-dimensional Computational Fluid Dynamics (CFD) model was developed to simulate the flow characteristics and combustion process inside the boiler. The eddy dissipation concept combustion model was applied to take into account detailed turbulent interactive reacting chemical reactions. Field experiments were also conducted on the original tangentially fired boiler under different operation conditions. Flame profiles videos were captured during experiments. A quick comparison of the experimental flame profile with numerical simulation results shows good agreement. Wall steam tubes overheating problem was observed, and the hot spots were identified based on a wide range of typical operation conditions. The effect of total fuel input and natural gas percentage on the furnace wall temperature were investigated.
