Babcock & Wilcox Power Generation Group, Inc. (B&W PGG) won a contract to deliver, erect and commission a dry flue gas desulfurization system for Interstate Power and Light Co.’s (IPL) 270 MW coal-fired Lansing Generating Station in Lansing, Iowa. IPL is a unit of Alliant Energy Corp. (LNT).
Under contract to Burns & McDonnell, B&W will deliver and erect a circulating dry scrubber with a lime and byproduct solids handling system for the reduction of emissions, including sulfur dioxide. B&W will also supply new bags for the plant’s existing pulse jet fabric filter. Babcock & Wilcox Construction Co., Inc. will erect the environmental equipment.
CDS technology — also known as circulating fluid bed flue gas desulfurization (CFB-FGD) — is applicable to a wide range of unit sizes and fuel sulfur content, but is ideally suited for smaller units that fire medium to high sulfur coals. In conjunction with the pulse jet fabric filter, the scrubber reduces an array of emissions with low capital and operating costs, and no wastewater production.
Construction on the Lansing project is scheduled to begin in 2014 and to be completed in 2015. Commissioning and startup will also occur in 2015.
Headquartered in Charlotte, N.C., The Babcock & Wilcox Co. provides clean energy technology and services, primarily for the nuclear, fossil and renewable power markets. B&W has locations worldwide and employs about 14,000 people, in addition to about 10,400 joint venture employees.
