When high-temperature boiler feedwater passes through a control valve, the pressure drop can exceed several thousand pounds per square inch, placing extreme stress on the valve body and internal parts. If those parts are not engineered and manufactured to the highest industry standards, there is a very real possibility of the severe conditions damaging or destroying the valve.

ERICO has developed a range of CWP grounding clamps that are ideal for use in applications including lightning protection, fault current ground, signal reference grid, and static ground. The clamps help minimize the possibility of damage from a lightening strike or other transient voltage by reducing the electrical potential between metallic objects and building systems. […]

Senate Democrats today unveiled the long-awaited 821-page discussion draft of the “Clean Energy Jobs and American Power Act,” a bill touted as “tough on corporate pollution”—but which will “improve the way the nation generates and uses energy,” without raising the “federal deficit by one single dime.”

Exelon Corp. is the third utility to leave the U.S. Chamber of Commerce in the past week, following moves by California utility PG&E Corp. and New Mexico–based PNM Resources. Exelon, the largest nuclear operator in the U.S. cited the “organization’s opposition to climate legislation” for its decision, an allegation the business federation refuted on Tuesday.

Dozens are feared dead after a 330-foot chimney under construction at a 1,200-MW coal-fired power plant collapsed last week in India’s Chhattisgarh state. Teams have so far retrieved 46 bodies from the debris.

A federal appeals board has ruled that the Environmental Protection Agency (EPA) will have to reconsider a long-contested air permit for the $3 billion Sithe Global Desert Rock coal-fired power plant on the Navajo Reservation, saying that the agency abused its discretion by not considering integrated gasification combined cycle (IGCC) technology in its analysis of best available pollution control systems for the plant.

The Electric Power Research Institute (EPRI) has joined American Electric Power (AEP) and Alstom in a validation of advanced carbon dioxide capture and storage (CCS) technologies at AEP’s Mountaineer Plant in New Haven, W.Va. The $76 million project is being watched closely around the world because it will be the first to capture carbon dioxide from a pulverized coal-fired power plant as well as inject it into a permanent storage site more than 7,800 feet underground.

NRG Energy’s proposed 112-MW project to repower its coal-fired Somerset Station in Massachusetts with plasma gasification technology has moved on to the due diligence phase of the Department of Energy’s federal loan guarantee program.

New geothermal projects representing as much as 7,100 MW of new baseload capacity were under development in 14 U.S. states between March and September 2009. When added to the 3,100 MW of existing capacity, these could bring U.S. geothermal capacity to more than 10 GW, a new report from the Geothermal Energy Association (GEA) shows.

By Kennedy Maize In 1979, researcher Renate Kimbrough of the Centers for Disease Control, part of the Department of Health Education and Welfare (now Health and Human Services), shocked the electrical world with an epidemiological study. She found that GE employees from the transformer works at Schenectady, N.Y., exposed to high levels of polychlorinated biphenyls […]
