Abstract
Forty fly ash samples were collected from thirteen full-scale coal-fired power plants equipped with cool-side ESPs. Five size fractions of the fly ashes were characterized to correlate mercury content in unburned carbon (UBC) with surface area and particle size of the UBC. The surface area of the UBC (SA/UBC) in the ashes varied from 20-150 m2/g. UBCs in ashes generated from burning PRB and PRB blend coals had higher surface areas and reactivities for adsorption of Hg in flue gas than the UBCs of the 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)]
