Experimental Research on Flue Gas Mercury Removal by Coal-combustion Derived Fly Ash
In this paper,the flue gas mercury removal efficiency by coal-combustion derived fly ash was experimentally evaluated on a vertical furnace system.The coal-combustion derived fly ash was characterized by using small angle X-ray scattering (SAXS) and scanning electron microscopy (SEM),and the effects of the incident light scattering intensity and fly ash surface features on the mercury adsorption efficiency of fly ash were analyzed.The fractal dimension of the fly ash was calculated by the data of SAXS.The results showed that the incident light scattering intensity may affect mercury adsorption efficiency of fly ash,and the higher the incident light scattering intensity,the higher the mercury adsorption efficiency by fly ash; however the fractal dimension has no direct effect on the mercury adsorption efficiency by the fly ash.
