Abstract
An apparatus and a method that uses generated alkaline, alkaline-earth, and/or silica/alumina aerosols as a multifunctional additive to scavenge sulfur oxides in flue gas, minimize poisoning effects of sulfur oxides on mercury sorbent performance, and enhance particulate matter capture in electrostatic precipitators and other particulate filter devices by conditioning the fly ash.
