BIRNS Inc., designer and manufacturer of lights for the nuclear power industry, introduced enhancements to the popular BIRNS Kelvin—a 16,000-lumen tungsten halogen light that features a 120 volt/1,000 W lamp with instant on/off and hot-restrike capability. Designed for underwater use in areas with high levels of radiation and nuclear contamination, the new model 5813 now […]

Statkraft began operating its 4-kW prototype osmotic power plant at Tofte, just outside Oslo, Norway, in 2009. Now the firm reports that it is close to developing a large-scale plant. In June, Statkraft and Japanese materials manufacturer Nitto Denko/Hydranautics signed an agreement for the development and supply of membranes specifically designed for use in large-scale osmotic power plants.

New Pig Corp. launched the “PIG UV-Resistant Spill Kit in a 95-Gallon Container” as an easy oil-spill clean-up solution to large outdoor spills. Suitable for outdoor use and storage, the PIG UV-Resistant Spill Kit is nontransparent, providing superior protection of absorbent contents from UV degradation during long-term storage outdoors. The container includes enough PIG oil-absorbent […]

Two years after it laid the foundation stone, Germany’s E.ON on June 27 opened Hungary’s most efficient combined cycle gas turbine (CCGT) power plant (Figure 7). The €400 million ($573 million) plant in Gönyü has a capacity of 433 MW and an efficiency of over 59%, E.ON claims. Siemens supplied the main components: an SGT5-4000F gas turbine, an SST5-5000 steam turbine, an SGEN 5-3000W generator, and the entire electrical and instrument and control equipment. The natural gas–fired power plant is of single-shaft design with the main components arranged in a single driveline.

Danray Products introduced a line of heavy-duty lathe carriage (saddle) shields that are designed for manual lathes or similar machines. The shield attaches directly to the backside of the carriage, so it moves with the carriage as the work piece is being machined. This provides a barrier between individuals and the point-of-operation hazard. The shield […]

The Tide Turns for Marine Energy Devices. Siemens Energy recently secured a 10% stake in Marine Current Turbines, the UK company that owns SeaGen, a 1.2-MW tidal power plant, which was commissioned in 2008 on the Irish Sea. Marine Current Turbines is planning to build a larger, 8-MW plant off the coast of Scotland by […]

With the U.S. economy still struggling, few things are as important as having an abundant, reliable supply of energy to help drive our recovery. Many American families are hurting and our businesses are being challenged to create new jobs. That’s why federal, state, and local public policies must balance the need for broader economic prosperity, […]

Longview Power, a 695-MW coal-fired power plant now under construction in Maidsville, W.Va., is scheduled to begin commercial operation later this year. The $2 billion project reached 580 MW in early June, just a month after completing the “first fire on coal” schedule milestone. Testing and tuning of the controls and various systems continue.

Enwave Energy Corp.’s district heating plants in downtown Toronto will be operating cleaner and more efficiently before the fall 2011 heating season begins when boiler upgrades now under way are completed. Enwave hired Benz Air Engineering (BAE) to design and install upgrades to all eight boilers inside Enwave’s Pearl Street Station. When the $20 million project is completed, the retrofits will produce energy savings exceeding $5 million per year. In addition, the company will receive incentives of $100,000 per boiler from Enbridge, its natural gas provider.

Steel piping systems used to convey coarse materials, often over long distances, are under constant attack from abrasion. In power plants, the materials are usually coal and limestone slurry. The common industry solution has been to install abrasion resistant (AR) pipe that is much harder on the Brinnell Scale than standard steel pipe. The harder the inner wall, studies have shown, the better it resists the gouging or plowing action of abrasive sliding particle flow.
