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

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.
