Babcock & Wilcox Co. (B&W) said its subsidiary, Babcock & Wilcox Power Generation Group Inc. (B&W PGG), has been awarded a contract to design and supply two spray dry absorber (SDA) units and associated equipment for Xcel Energy's coal-fired Pawnee Generating Station in Colorado.

The SDA systems are designed to control sulfur dioxide (SO2) emissions from the single-unit, 544 MW plant. The contract scope also calls for B&W PGG to supply atomizers, a reagent preparation system, structural steel and commissioning of the project.

Material delivery is scheduled for 2013, with tie-in of the SDA units expected in the fall of 2014.
