Morgantown Energy Associates filed a Nov. 19 application with the West Virginia Department of Environmental Protection for an air permit approval covering the installation of a selective non-catalytic reduction system for NOx control on its coal-fired power plant in Morgantown, W.Va.
The company said the SNCR is needed to control NOx emissions under the U.S. Environmental Protection Agency’s Mercury and Air Toxics Standards. The SNCR would use either urea or aqueous ammonia. Injection portals will be installed in the flue gas system of the plant. The company is shooting for an early-2016 startup for the SNCR system. The company indicated it has a MATS compliance extension.
The plant is fired with two circulating fluidized-bed combustion systems and primarily uses waste coal for fuel. The company said that to meet the MATS SO2 limit, it has to increase the limestone injection level into the CFB combustors by up to 30%, which will require an increase in fuel feed of up to 3% to allow for the calcination of the limestone. The higher fuel feed will lead to more NOx emissions once this coal is burned, thus the need for the SNCR.
This plant is a cogenerator, supplying steam to West Virginia University facilities and power to Monongahela Power, a unit of FirstEnergy (NYSE: FE).
