Minnesota Power is celebrating the start of construction on its $350 million project to control mercury and other emissions at its 585-MW Unit 4 of the Boswell coal-fired power plant in Itasca County, Michigan, according to a report from the Duluth News Tribune.
The project, which was approved by regulators last summer, will reduce mercury emissions by 90 percent, according to the report. The retrofit, combined with other emissions control upgrades since 2006, will combine to cut the plant’s total emissions by 70 percent by 2016.
Alstom will provide the emission control system for the plant, using its NIDTM semi-dry flue gas desulphurization system.
