Influences of Waste Iron Residue on Combustion Efficiency and Polycyclic Aromatic Hydrocarbons Release during Coal Catalytic Combustion

並列摘要


Effects of adding waste iron residue on the combustion efficiency and the removal of Polycyclic Aromatic Hydrocarbons (PAHs) during coal combustion were investigated in a laboratory scaled drop tube furnace at a temperature range of 950- 1250°C. The experimental results indicated that adding 0.5% waste iron residue had a good performance on enhancing combustion efficiency during coal combustion. Meanwhile, the addition of 0.5% waste iron residue was also favor for reducing PAHs emission as well as PAHs TEQ concentrations during coal combustion at a temperatures range of 950- 1250°C. With adding 0.5% waste iron residue (WIR), the coal combustion efficiency was enhanced by 6.15%, and the total PAHs concentration in flue gas was decreased by 44.94% at 1150°C. The maximum removal of the total PAHs TEQ concentration was as high as 45.24% at 1250°C.
