Control of Mercury Emissions from Coal-fired Electric

boilers is Hg0. Control of mercury emissions from coal-fired boilers is currently achieved via existing controls used to remove particulate matter (PM), sulfur dioxide (SO2), and nitrogen oxides (NOx). This includes capture of Hgp in PM control equipment and soluble Hg 2+ compounds in wet flue gas desulfurization (FGD) systems.
