In “Dry Injection of Trona for SO3 Control” (May 2010), NH4HSO4 is ammonium bisulfite. In the June “Focus on O&M,” the engines shown in Figure 6 each have eight cylinders. June’s “Competition for Offshore Turbine Market Heats Up” stated that drive or gearless turbines accounted for 14% of the world’s installed offshore capacity in 2009. […]

This May, following two years of construction, Siemens Energy put into operation Irsching 5, an 847-MW advanced combined-cycle power plant near Ingolstadt, Germany. The plant’s owner, Gemeinschaftskraftwerke Irsching GmbH—a joint venture of E.ON, Mainova, and HEAG Südhessische Energie—features two SGT5-4000F gas turbines, one SST5-5000 steam turbine, three hydrogen-cooled generators, electrical systems, and Siemens’ SPPA-T3000 instrumentation and control system.

The competitive push for more efficient power generation prompted the management of East Kentucky Power Cooperative’s Spurlock Station to provide training and to implement standardized work processes in order to achieve higher productivity. To that end, Spurlock’s management collaborated with salaried and hourly personnel to design and implement work process optimization. Two years later, their proactive, operations-driven culture is promoting continuous improvement at this facility.

Nearly a quarter-century after the Chernobyl nuclear power station disaster in Soviet Ukraine, Russia has been making deals with energy-starved nations all over the globe to help them build new nuclear power plants using Russian second-generation reactor technology.

Steve Elonka began chronicling the exploits of Marmaduke Surfaceblow—a six-foot-four marine engineer with a steel brush mustache and a foghorn voice—in POWER in 1948, when Marmaduke raised the wooden mast of the SS Asia Sun with the help of two cobras and a case of Sandpaper Gin. Marmy’s simple solutions to seemingly intractable plant problems remain timeless. This Classic Marmaduke story, originally published more than 50 years ago, illustrates that although solutions may be easy to identify, the challenge is often in the implementation. Sometimes a little horse sense is all that is necessary.

While the U.S. awaits congressional action on a cap-and-trade program that could possibly be limited to just the utility sector, Canada is moving, starting in 2011, to phase out older coal power plants and replace them with natural gas–fired plants. The announcement, made this June by Environment Minister Jim Prentice prior to the G8 and G20 summits, could have serious implications for coal-fired generators in the country.

Eliminate waste in coal, gas, or nuclear power plant construction through a holistic application of lean principles.

This June, AREVA installed the reactor pressure vessel (Figure 6)—the core of the unit—at the world’s first EPR project, which is under construction in Finland. Now the company will engage in a flurry of installation activities for heavy nuclear components, including lifting into the reactor the first of the four steam generators. Most of the work is expected to be completed by the end of 2012, with power production beginning in 2013.

ABB’s new 266 series is an optimized pressure transmitter family that combines modern electronic pressure measurement with the company’s unique human machine interface (HMI) in one common product series, providing base accuracy from ±0.025% to ±0.06%. The series offers the industry’s best draft range, ABB claims. For combustion airflows, this means exceptional resolution with tighter […]

The U.S. Army Corps of Engineers earlier this year awarded its first Section 10 permit ever to a commercial wave-powered demonstration facility planned for installation in the Gulf of Mexico. The novel offshore platform, dubbed the SEADOG, will use a buoy and piston mechanism combined with a water wheel to generate electricity and desalinate water.

HD Electric Co.’s Phase Rotation Meter (PRM) is used to determine the leading phase of any two phases in a three-phase conductor system. The PRM is a dual-range 0 to 5 kV and 0 to 15 kV device that can be used as high as 45 kV when optional resistor sticks are added. It consists of two […]

Sweden Reverses Ban, Approves Nuclear Reactor Replacements Sweden’s parliament on June 18 reversed an earlier decision and passed the center-right coalition government’s landmark proposal, made last year, that allows for the replacement of the country’s nuclear reactors at the end of their life span. The country had voted in 1980 to phase out its 12 […]

A new family of Rotating Line Moles (RLM) from NLB gives users more than 40 choices for cleaning pipes and tubes with high-pressure water. Designed for tubes with diameters from 0.5 inch to 1.5 inches (1.27 cm to 3.81 cm), the family features operating pressures of 10,000 psi or 20,000 psi (700 bar or 1,400 […]

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.

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 […]

A federal appeals court on Monday reversed a January 2009 ruling by a North Carolina U.S. District Court that had declared emissions from the Tennessee Valley Authority’s (TVA’s) coal plants in eastern Tennessee and Alabama a public nuisance in North Carolina and ordered the nation’s largest public power provider to install expensive control technologies. The appeals court said the ruling was “flawed for several reasons.”

The $3.5 billion Taylorville Energy Center (TEC), a proposed integrated gasification combined cycle (IGCC) plant with carbon capture and storage (CCS), has been awarded a $417 million investment tax credit under a program jointly administered by the Department of Energy (DOE) and the U.S. Treasury Department. The tax credit is believed to be the largest ever granted to a single project.

PPL Montana will reportedly ask the U.S. Supreme Court to review an order from the Montana Supreme Court that requires it to pay “rent” for use of the riverbeds on which the company’s hydroelectric dams are built.

Texas Attorney General Greg Abbott on Monday legally challenged the U.S. Environmental Protection Agency’s (EPA’s) disapproval of the state’s flexible permits program, a system which allows power plants, factories, refineries, and other industrial plants to exceed emission limits in certain areas as long as they stay within overall limits.

Hoosier Energy, an Indiana-based rural cooperative, on Friday reached an agreement with the U.S. Environmental Protection Agency (EPA) and the Indiana Department of Environmental Management (IDEM) to resolve alleged New Source Review (NSR) violations of the Clean Air Act.

Tampa Electric said on Monday it is participating in two DOE-funded demonstration projects at the company’s Big Bend and Polk Power Stations. The projects are designed to advance carbon dioxide capture technologies and could lead to the development of technologies on a large scale.

By Kennedy Maize Washington, D.C., July 22, 2010 — Is anyone really surprised that Senate majority leader Harry Reid (D-Nevada) has finally declared major energy legislation dead? For weeks, Reid has been singing words from a country classic that I’m sure he knew were false: “Mother’s not dead, she’s only sleeping.” Today, he recognized the […]

The Department of Energy’s (DOE) failure to systematically assess development of carbon capture and storage (CCS) technologies renders it unable to gauge their maturity and to provide resources required to move these technologies toward commercial demonstration, the Government Accountability Office (GAO) found in a report released to the public last week.

With only about 13 days remaining before the U.S. Senate’s month-long summer recess is scheduled to begin, concerns are mounting about whether it may be too late to delve into an “energy-only bill,” let alone a “utility-only” carbon-curbing bill.

At least four militants reportedly stormed into a hydropower plant in Russia’s volatile North Caucasus region early this morning, shooting dead two security guards before detonating four bombs in a turbine hall and shutting down the plant.

The International Energy Administration (IEA) alleges, based on preliminary data, that China has overtaken the U.S. to become the world’s largest energy user. But China on Tuesday rejected that report, saying the IEA’s data is unreliable. The IEA said that China consumed 2.252 billion tons of oil equivalent in 2009—4% more than the 2.17 billion […]

A project piloting underground coal gasification (UCG) technology in Australia was last week shut down for tests by the Queensland Government for carcinogenic chemicals in nearby water bores.
