Abstract
Studies show that mercury capture by fly ash increases with an increase in the unburned carbon (UBC) content in the fly ash. In the present study, 40 fly ash samples generated from burning various coals in different type of boilers were collected and characterized to correlate the UBC properties with the Hg capture. UBCs in ashes generated from burning Powder River Basin (PRB) and PRB blend coals had higher surface areas and reactivities for adsorption of Hg in flue gas than the UBCs of the eastern bituminous (EB) ashes. The Hg content and UBC particle size could be correlated for the PRB or PRB blend ashes, but not for EB ashes. The coal type had more impact on the Hg adsorption reactivity of the UBC than the boiler type. on SciFinder(R)]
