Control of Mercury Emissions from Coal-fired Electric

2016-7-28 · average capture of Hg in plants equipped with a CS-ESP is 36 percent for bituminous coal, 3 percent for subbituminous coal, and 0 percent for lignite. Based on ICR data, it is estimated that existing controls remove about 36% of the 75 tons of mercury input with coal in U.S. coal-fired boilers. This results in current emissions of 48 tons of

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
