St. Clair Power Plant

Units 1 – 4 are 163 MW Babcock & Wilcox boilers tied to GE and Allis-Chalmers steam turbines.

Unit 6 is a tangentially fired Combustion Engineering dual furnace boiler tied to a Westinghouse turbine.

Unit 7 is also a tangentially fired Combustion Engineering boiler tied to a Westinghouse steam turbine.

[3] St. Clair Power Plant came online in August 1953, and was the largest in the DTE Energy network.

Later, units 5, 6 and 7 were added to meet growing demands for power in Metro Detroit, with St. Clair producing 1571 MW.

In addition, low NOx burners and overfire air ports have been installed on all of St. Clair's generating units.

[7] On August 11, 2016, at around 6:30 pm local time, a generation unit at St. Clair Power Plant caught fire.

In the summer months, for example, the blend trends toward 70/30 on Units 6 and 7 to gain additional generating capacity by firing more Eastern coal with its higher heating value.

The higher sulfur content of the Eastern coal also helps prevent opacity excursions with the electrostatic precipitator on Unit 7.

[7] The Western coal is delivered to Superior, Wisconsin, by unit train and then barged to St. Clair on 60,000-ton ships.

The St. Clair and Belle River Complex, along with the rest of Detroit Edison's generating facilities are ISO 14001 certified.

[citation needed] Sulfur emissions could be lowered by using flue-gas desulfurization units, better known as SO2 "scrubbers", like those of Lambton Generating Station across the St. Clair River.

Currently, these scrubbers are being installed at DTE's Monroe Power Plant, and may eventually be added at the St. Clair site as well.
