Corps of Engineers awards contract for Fort Wainwright power plant

Posted: Wednesday, June 05, 2002

ANCHORAGE (AP) -- The Army Corps of Engineers has awarded an $18.5-million contract for emission control system improvements for the Fort Wainwright power plant to GHEMM Co. of Fairbanks.

Construction will begin this month and be complete in late 2004.

The new facility, commonly referred to as ''the bag house,'' will bring the power plant into compliance with the Federal Clean Air Act.

The project will consist of six new full-stream bag houses, one for each boiler, in a new building adjacent to the power plant, according to Corps project manager John Malecha.

The 40-foot-high bag houses function like big vacuum cleaner bags. Each bag is about 9 inches in diameter and 15 feet long. Exhausts from the boiler flow through the bags, which filter particulate from the air before emissions are released into the atmosphere.

Each bag house will include five modules containing 220 bags each.

The emission control project is part of a $45 million upgrade of the 50-year-old central heating and power facility. The plant burns nearly 200,000 tons of Alaska coal annually.
