A £42 million marine power infrastructure project that will function as an “electrical socket” in waters 50 meters (m) deep and nearly 16 kilometers (km) off the coast of Cornwall in South West England set sail toward its proposed location this July.

Hamworthy Peabody Combustion introduced the ECOjet ultra-low-NOx burner. Offering ultra-low burner nitrogen oxide capacities (<30 parts per million) with little or no flue gas recirculation, the burner can be used with a full range of gaseous fuels and with package, industrial, and utility boilers, including single and multi-burner wall-fired, turbo, and other boiler types. Ignition […]

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.

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 […]

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 […]

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 […]

The SEL-734P Portable PQ Meter is a new metering solution from Schweitzer Engineering Laboratories (SEL) that addresses the need for complete and portable power quality monitoring. In addition to the meter, the kit includes three-phase voltage and current inputs, voltage leads, and split-core CTs, all secured in a ruggedized case. ACSELerator QuickSet SEL-5030 software, included […]

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.

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 […]

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.
