Control of Mercury Emissions from Coal Fired Electric

2016-7-28·As will be discussed, 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 particulate-bound mercury in PM control equipment and soluble mercury compounds in wet flue gas desulfurization (FGD)
