Fuel for power generation will account for about 55% of demand-related energy growth through 2040, ExxonMobil forecasts in its latest annual energy forecast. Like several other forecasters, the Irving, Texas–based oil and gas company also predicts that natural gas will emerge as the leading source of electricity generation by 2040....

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....

After years of development, design, and construction, your plant is finally nearly ready for startup. But don’t light that cigar yet—at least not until you’ve developed a strategy for commissioning your water cycle chemistry. Root causes of corrosion can be predicted and avoided. The best way to avoid corrosion is to develop and implement plant-specific cycle chemistry commissioning guidelines....

Because Powder River Basin (PRB) coal is smaller, more friable, and contains more fine particulates than bituminous coal, controlling the fugitive dust generated as PRB coal moves from bunker to burner tip is problematic. The challenge for material-handling systems at power plants that have switched coals is to minimize this dust and capture it cost-effectively and without compromising safety....
