A utility evaluated various methods of obtaining a NO_x reduction of at least 30%, as required by upcoming regulations for its boiler, which originally produced 0.54 lb of NO_x/million Btu at 410 MW full load. Nalco Mobotec engineers performed a computational fluid dynamics (CFD) simulation of the boiler to first understand the boiler’s combustion process and then determine the most economical method to achieve the required NO_x reduction.

As fluid passes through Exact Flow’s new DX-DL dual-rotor turbine flowmeter, the dual rotors become hydraulically coupled due to their counter-rotation. Not only does this allow the rotors to overcome the inertia and drag that typically affect single-rotor turbine flowmeters, it also extends the flow range to 500:1—five times the 100:1 flow range of a […]

Enclosure manufacturer Rittal Corp.’s latest products are designed to be incorporated into electrical systems to help ensure safety against arc flash hazards. Data interface flaps, shown here, provide rapid system access via integrated USB, SUB-D9 RJ 45, and NEMA 5-15 sockets when needed. The affected enclosure remains closed and is thereby protected from ambient influences […]

GE Sensing & Inspection Technologies’ new family of ultrasonic flaw detectors incorporates conventional and phased array ultrasound technology in three upgradeable models: Phasor CV, Phasor 16/16 Weld, and Phasor XS. Each solution, designed for applications ranging from corrosion monitoring to defect detection and sizing, is compliant with all major inspection codes. The Phasor XS (shown […]

An advanced seal technology for hydraulic bolt tensioners recently developed by UK-based Boltight Ltd. takes advantage of the latest composite materials to eliminate oil leakage while allowing the tensioning piston to be retracted more easily after use. The new seals are a two-piece self-energizing design with an “O” ring made from a self-lubricating and durable […]

Hawk Measurement Systems has launched a new line of “fourth generation” sonar transducers designed for improved sensing of interface levels in clarifiers and thickeners. The new transducer designs include three to seven sonar crystals mounted in a single head. Each sonar array produces a concentrated sonar beam, providing more emitted power and collecting more returned […]

Desperate to score points in a crucial state where they are in the double-digit dumps, the Republican McCain-Palin presidential ticket rolled out their heartfelt support for “clean coal technologies” at a rally in Scranton, Pa., this week.

President Bush on Friday signed into law a measure to renew critical energy tax incentives that had been set to expire at the end of this year. The measure, which gained new life after a political impasse had left its future uncertain only the week before, was one of many added to the financial bailout […]

UK Prime Minister Gordon Brown last week created a new government department for Energy and Climate Change (DECC) as part of his latest cabinet shuffle. The new entity will take on several issues affecting the UK power industry, including soaring wholesale prices resulting from a squeeze in generating capacity, the nation’s crumbling power infrastructure, and […]

U.S. baseload generation capacity reserve margins declined to 17% last year, and with demand expected to outpace capacity growth, the nation could face significant risk of costly power brownouts and blackouts as early as next summer, suggests a new study released by NextGen Energy Council.   The nonprofit organization is composed of a wide variety […]
