BEIJING, June 8 — Babcock & Wilcox Beijing Company (B&WBC) will supply the pressure parts for eight supercritical boiler and environmental equipment for Texan power plants, after its parent company Babcock & Wilcox Company (B&W), a subsidiary of McDermott International, signed a US$1 billion (7.85 billion RMB) memorandum of understanding (MOU) with US energy supplier TXU.
The eight boilers, each with a capacity of 858MW, will be B&W supercritical Spiral Wound Universal Pressure (SWUP) units, the largest of this kind under construction in the US to date. The units will burn Powder River Basin coal. SCR systems will be installed to reduce NOx emissions to below the levels required by federal and state environmental standards.
B&WBC’s scope includes boiler pressure parts and auxiliary equipment such as pulverizers, sootblowers, fans and drives, flues and ducts and technical advisors for construction, commissioning and training.
The new boilers will be installed at the following TXU power stations in Texas: Big Brown (Freestone County), Lake Creek (McLennan County), Martin Lake (Rusk County), Monticello (Titus County), Morgan Creek (Mitchell County), Valley (Fannin County) and two at Tradinghouse (McLennan County).
Design of the boilers is currently underway at B&W’s headquarters in Barberton, Ohio.
In a statement, B&W said B&WBC will provide a majority of the pressure part fabrication. Delivery of materials is scheduled to begin in 2007. The first unit is targeted to be online in the fall of 2009 with the rest online in sequence through mid-2010.
The B&WBC manufacturing facility was established in 1986 and is B&W’s largest manufacturing facility with more than one million square feet (93,000 square meters) of manufacturing space and approximately 2,000 employees. B&WBC operates its own heavy drum shop, the largest in northern China.
