Brunner Island Retrofit Project
Featured as one of POWER magazine’s top plants in October 2010, PPL Brunner Island features pollution control upgrades through flue gas desulfurization (FGD) systems installed by Shaw. Our work at the clean coal-fired plant – which included engineering, design, procurement, construction, commissioning and startup – includes Units 1, 2 and 3 for a total of 1,540 MW.
As a full-service engineering, procurement and construction organization, Shaw serves as a one-stop shop for all air quality control needs on new and existing units, helping our clients to meet their goals of clean, efficient and economical electricity generation. At Brunner, our air quality control services are helping to remove up to 97 percent of incoming sulfur dioxide at the plant.
The FGD systems at Brunner are composed of limestone forced oxidation scrubbers that produce synthetic gypsum as a byproduct. The gypsum byproduct is shipped offsite to wallboard manufacturing facilities.
In addition, the plant features the following:
- A single absorber system that treats the combined flue gas from Units 1 and 2
- A dedicated absorber system that treats flue gas from Unit 3
- A dual-flow, sing-tray design on absorbers
- Voluntary Protection Program “STAR” certification from the federal Occupational Safety and Health Administration
In addition to the FGD systems, Shaw also provided engineering services for an electrostatic precipitator replacement on Unit 2 and a retrofit on Unit 3. The small footprint for Unit 2 contributed to the project’s scope and complexity. For Unit 3, new inlet fields were installed on the existing precipitators, while existing wire plate precipitators were demolished. The modifications significantly reduce particulate emissions from the plant and began operations in 2009 and 2007, respectively.
