The world’s first supercritical pulverized coal–fired low mass flux vertical tube Benson boiler is Jinzhushan 3, located in the Hunan Province of the People’s Republic of China. The 600-MW Babcock & Wilcox Power Generation Group Inc. once-through boiler burns Chinese anthracite using downshot pulverized coal (PC) technology. Part 1 of this three-part article presented a summary of the project design features. Part 2 discussed the boiler technology. This third and final part reviews the plant’s performance test results.

Proposed U.S. Environmental Protection Agency rules and a greater reliance on newer generation technologies have put the nation’s aging fossil-fueled generation units at risk of retirement. The numbers demonstrate that the U.S. power generating fleet is older than you may believe.
