Jamar Company SCR Critical Lift Analysis at Boswell Energy Center

Project Type: Design Services Boswell Energy Center; Cohassett, MN

Client: Jamar Company

LHB’s Industrial Group designed the critical lifts for the air system manufactured by Jamar Company using this 400-foot crane at a Minnesota Power energy center. The Mammoet crane is one of the largest mobile cranes in the world and is capable of lifting 1,000 tons. The crane was used to erect a new structure and equipment that will help lower emissions. Regional utility Minnesota Power, an ALLETE company, understands the importance of protecting the environment and its customers. It was no surprise, then, when the company elected to install additional advanced emission control equipment to reduce mercury, nitrogen oxide and sulfur dioxide at one of its energy plants. LHB’s Industrial Group provided civil engineering and structural steel design, as well as piping engineering services for hundreds of feet of emission control process piping. “The upgrade builds on our track record of environmental stewardship in a region that is home to the Boundary Waters Canoe Area Wilderness, Voyageurs National Park, and the Apostle Islands National Wilderness Area,” notes ALLETE CEO Don Shippar. Minnesota Power already operates all of its coal-based facilities at 70 percent below current air emission requirements. The new emission reduction installations are addressing new requirements that will take effect over the next several years. The improvements are targeted to reduce mercury emissions by up to 90 percent and cut nitrogen oxide and sulfur dioxide emissions by more than 80 percent.
