The trial operation of a steam loop for more than 17,000 hours at temperatures exceeding 760C (1,400F)—the highest ever tested at a pulverized coal plant—have wrapped up at Plant Barry Unit 4 in Alabama

If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to be much more demanding in actual execution. The first problem is the environment inside the collection hoppers, which is extremely challenging […]

Plant engineers at Eskom’s Majuba Power Station in South Africa have been continuously looking for ways to improve efficiency and reliability. The six-unit, 4,000-MW, supercritical coal-fired plant was experiencing an efficiency decrease of 5% to 7%, which plant engineers determined was caused by poor performance of the actuators on their condensate level control valves (CLCVs). […]

The first full-scale commercial post-combustion carbon capture and sequestration (CCS) project at an operating coal-fired power plant is now online in Estevan, Saskatchewan, roughly 10 miles north of the U.S. border. The heart of the $1.4 billion project at Boundary Dam Power Station is the rebuilt 110-MW Unit 3, originally commissioned in 1970. The project, […]

Bad weather, unforeseen setbacks, and even natural disasters are far from unheard of during power plant construction. But there may be no plant that experienced the sort of construction hardships that Tokyo

Affirmative defense provisions can no longer insulate generators from monetary penalties for Clean Air Act violations that result from facility startup, shutdown, and equipment malfunction, the Environmental Protection Agency (EPA) has proposed.  In a supplemental notice of proposed rulemaking (SNPR) published on Sept. 17 in the Federal Register, the agency proposes to revise its February […]

While several methods exist for sizing collector pipes on steam lines, the results obtained from the various approaches can be quite different. This article will show how design parameters can be used to calculate the dimensions much more accurately. In the steam lines of thermal and nuclear power plants, condensed steam is usually discharged from […]

U.S. coal power plants are finding that they need to comply with an increasing number of stringent environmental regulations, and while nobody in any industry looks forward to additional regulatory burdens

Reactor pressure vessel (RPV) shells in the existing U.S. fleet of nuclear power plants were typically constructed by forging ring segments from ingots of low-alloy steel offering sufficient fracture toughness

Power plants are, with good reason, almost universally regarded as fixed assets to be operated, maintained, and retired on the spot where they were built. The idea of relocating something as large and
