Reducing Operating Costs and Risks of Hg Control with Fuel

For coal-fired boilers firing bituminous or subbituminous coal, the MATS emission limit for mercury is 1.2 lb/TBtu, computed on a 30-day rolling average basis. This is a multi-pollutant rule, which can increase the complexity of finding a compliance solution. The control of particulate matter (PM) must be accomplished while
