B&W Clean Power Production Case Studies

Unique Construction Approach to Refinery Boiler Refurbishment

An oil refinery in Edmonton, Alberta, Canada was experiencing boiler failures that were having a frequent and negative impact on its operations. This project showcases how the linkage of creative engineering, material supply and advanced construction planning come together to meet ambitious goals and minimize impacts to customer operations during and well after project completion.

North American Pulp Mill — Diamonized® Feed Tubes

Premature packing wear from normal cycling caused excessive steam leaks in the sootblower feed tubes located in the boiler’s superheater. A solution was needed that would extend the life of the feed tubes and minimize maintenance.

Submerged Grind Conveyor Helps Plant Eliminate Ash Pond

Platte River Power Authority’s Rawhide Energy Station, northwest of Wellington, Colorado, is among the most efficient plants in the western U.S., averaging an equivalent availability factor of more than 90 percent and an average capacity factor of nearly 90 percent. The plant generates and transmits power to homes and businesses throughout its owner-communities in Estes Park, Fort Collins, Longmont and Loveland, Colorado.

Integrated Refinery & Petrochemical Complex (IRPC) 2

IRPC, the first fully integrated petrochemical complex in Southeast Asia, is located in an industrial area of Rayong, Thailand, with energy and sea port operations to support the area’s businesses. A subsidiary of Global Power Synergy PCL, IRPC Clean Power Company, Ltd., (IRPC CP) owns and operates a cogeneration plant that produces and sells steam and electrical power.

Industrial Boilers for Canadian Oil Sands

Alberta’s high-quality oil sands deposits are a major contributor to Canada’s economy and North America’s energy needs. Babcock & Wilcox (B&W) was selected to help advance one site’s responsible development and efficient production of its estimated 4.6 billion barrels of recoverable bitumen resource.

Waste-to-Energy Technology — Skærbækværket / Skaerbaek Plant

Babcock & Wilcox Renewable (B&W) designed, manufactured and commissioned two biomass boilers for the Skærbækværket power plant in Denmark. The project allows the combined heating and power plant to supply approximately 60,000 households with clean and reliable district heating and electricity while reducing carbon emissions.

Weston Unit 4 Plant — Wisconsin, USA

B&W installed DRB-4Z® low NOx burners and overfire air, a selective catalytic reduction (SCR) NOx removal system, a dry flue gas desulfurization (FGD) system, a pulse jet fabric filter particulate collector and a powdered activated carbon injection system for mercury removal.

Tanjung Jati B Units 1 and 2

This installation of environmental equipment at the Tanjung Jati power plant includes low NOx burners, a wet FGD system and electrostatic precipitators.

Prairie State Generating Company

The boilers burn coal from a mine adjacent to the power plant. Electricity produced is dedicated to supply eight Midwestern-based public power utilities serving customers across nine states. The design of these boilers was modified to adapt to the requirements of the Prairie State Energy Campus project, including a change in fuels from Powder River Basin sub-bituminous coal to Illinois bituminous coal.

Waste-to-Energy Technology — Amager Bakke / Copenhill Plant

Copenhagen’s state-of-the-art Amager Bakke sets new standards for environmental performance, energy efficiency and waste treatment capacity.

Hawthorn Unit 5 Plant Rebuild — Missouri, USA

An explosion during a maintenance outage on February 17, 1999, destroyed the original Hawthorn Unit 5 boiler. In August 1999, B&W was released to design, supply, erect and commission a complete replacement boiler on an accelerated schedule. The new boiler began generating electricity in June 2001, only 22 months from project commencement.

Spiritwood Station Plant — North Dakota, USA

Combined heat and power plant will provide process steam for an adjacent malt plant and will normally generate approximately 56 MW net of electricity for the regional transmission grid.
