When heat exchanger tubes—sometimes numbering a thousand or more per unit—begin to crack or wear, the effects can lead to a cascade of subsequent failures in adjacent tubes. If too many tubes are plugged, heat exchanger effectiveness is compromised, and power generation may be curtailed. If conventional mechanical plugs are used, they can break loose, leak, and fail. At that point, the replacement of a very costly heat exchanger is imminent.

LUDECA has introduced VIBXPERT II, the latest addition to its PRUEFTECHNIK family of portable route-based vibration data collectors. VIBXPERT II is rugged and lightweight and combines the advantages of a rapid processor with an energy-efficient color VGA display. Enhanced with an Fmax of 51KHz and up to 102,400 lines of resolution, all machinery problems can […]

Power plant operators, especially those located in countries with enforceable carbon emissions standards, are concerned about their CO₂ emissions. But for Helsingin Energia—which provides power, heating, and cooling for Helsinki, Finland’s 300,000 residents—the main concern is local warming, not global warming. In Helsinki, temperatures on midsummer afternoons only reach an average 21C, and for half the year daytime temperatures are below 10C.

Heise precision pressure instruments provide the high-accuracy measurements required for critical test, calibration, and process applications. The unique blend of product configurations includes the Heise 0.1% precision dial pressure gauge, the modular PTE-1 handheld calibrator, and high-accuracy digital pressure indicators and transducers. With ranges from 0.25 inches of water to 100,000 psi and accuracies to […]

Stacks at power generating stations may be low maintenance, but they are not no maintenance. The cost of preventing corrosion may be as little as $10,000, but the cost of repair or replacement could be many times that or even put your plant out of commission until the stack problem is corrected.

A proven solution for immediate and long-term job creation came from President Barack Obama and his administration earlier this year: investment in U.S. nuclear energy. Bulldozers in Georgia are already on the move and making preparations for expansion of a nuclear plant that has achieved several approvals, and long-awaited jobs in the skilled labor sector could materialize there within months.

In October of last year, the North American Electric Reliability Corp. (NERC) issued a study finding that maintaining electric reliability will require significant acceleration in the siting and construction of new transmission lines. The NERC study is indicative of growing concerns that changes to the current transmission planning process are necessary to maintain reliability and accommodate interconnection of the massive amounts of renewable resources expected to come online over the next 10 to 20 years.

Luminant used remnants of the ill-fated Twin Oaks and Forest Grove plants (which were mothballed more than 30 years ago) to build the new two-unit 1,600-MW Oak Grove Plant. Though outfitted with equipment from those old plants, Oak Grove also sports an array of modern air quality control equipment and is the nation’s first 100% lignite-fired plant to adopt selective catalytic reduction for NO_x control and activated carbon sorbent injection technology to remove mercury. For melding two different steam generators into a single project, adopting a unique and efficient “push-pull” fuel delivery system, assembling a tightly integrated team that completed the project on time and within budget, and for completing what was started almost four decades ago, Oak Grove Power Plant is awarded POWER magazine’s 2010 Plant of the Year award.

By Kennedy Maize Washington, D.C., July 29, 2010 — More hurdles have arisen for the nascent nuclear renaissance. It now appears that federal loan guarantees for new nukes could turn out to be a dead end, meaning that only two utilities, at most, will get Department of Energy support for new reactors. In passing the […]

By Kennedy Maize Washington, D.C., July 28, 2010 — Will global warming overwhelm the U.S. with illegal Mexican immigrants? That’s the preposterous claim by three Princeton academicians in an online article for the Proceedings of the National Academy of Sciences, and it has prompted guffaws from among sophisticated readers. In the article – “Linkages among […]
