B&W will design and install the sulfur dioxide (SO2)-reducing equipment, also known as scrubbers, on the plant's three boilers: Units 1 and 2 are 800 MW each, and Unit 3 is 1,300 MW. At a total of 2,900 MW, the Amos Plant is the largest power plant on the AEP system and one of the largest coal-fired plants in the world.
Units 1, 2 and 3 -- started up in 1971, 1972 and 1973, respectively -- are supercritical, dry-bottom boilers powered by a blend of low-sulfur coal and Northern Appalachian Basin high-sulfur coal. B&W's WFGD systems are designed to reduce SO2 emissions.
"Since our first scrubber installation in 1973, we have supplied WFGD systems for nearly 90 units totaling more than 53,000 MW," said B&W President David L. Keller. "We value the confidence AEP places in our experience, the operating record of our equipment and in our ability to help the Amos plant team meet critical air quality objectives."
The contract calls for the supply of two absorber islands, single absorber towers for Units 1 and 2 that each measure 68.5 feet in diameter and more than 159 feet high, and two absorber towers for Unit 3 that measure 61 feet in diameter and 153 feet high. Also included are three limestone ball mills with silos and classifiers, associated tanks, agitators and pumps for the reagent preparation island; three horizontal vacuum belt filter dewatering trains and associated hydroclones, tanks, agitators and pumps for the dewatering island; and absorber oxidation air compressors, absorber recycle system and tanks, agitators and pumps for the towers.
Design and engineering for the three WFGD systems are currently underway at B&W's headquarters in Barberton. B&W subsidiary Babcock & Wilcox Construction Co., Inc., will erect the equipment. Unit 3 is scheduled to be completed by the end of 2007, and Units 1 and 2 are scheduled to go online by the end of 2008.
