Fauske & Associates LLC (FAI) recently patented a specialized pipe clamp to seat vibration-sensing equipment. A beam attached to the clamp protrudes through the pipe insulation. The beam is partially hollow and vented to promote cooling so that accelerometers can be installed on the tip of the beam outside the high-temperature and/or radiation area for […]

It has been a decade since an R0 compressor blade was liberated on one of the eight Frame 9FA combustion turbines at CLP Power Hong Kong’s Black Point Power Station. This catastrophic failure eventually led to GE’s recommendation that operators severely limit or cease using online water wash (OLWW), inlet fogging, wet compression, and evaporative coolers on F-Class turbines.

The new portable, nonmetallic Flex-I-Liner rotary peristaltic pump from Vanton Pump and Equipment Corp. evacuates drums and totes containing acids, caustics, salts, chlorides, and reagent grade chemicals, without corrosion of the pump or contamination of the fluid. The self-priming design has no seals to leak or valves to clog and can run dry for extended […]

In 2002, California enacted legislation authorizing municipalities to establish Community Choice Aggregation (CCA) programs. In September 2012, the San Francisco Board of Supervisors adopted “CleanPowerSF” to be the CCA program available for city residents. Its supporters describe CleanPowerSF as “a 100% renewable energy alternative.” Supervisor David Campos exalted that CleanPowerSF “will stimulate the local economy, create jobs and most importantly secure our independent, clean energy future.”

As the largest solar plant of its type in the world, the 30-MW Alamosa Solar Project is currently enjoying its place in the sun. The innovative project consists of 504 concentrating photovoltaic (CPV) solar trackers, each featuring a CPV solar cell panel assembly mounted on a support column. The modular design of the assembly allows the project to easily accommodate future improvements in cell technology.

Note on the Oconee Top Plant Some of our readers may have been confused by the wording of a press release about our November issue’s nuclear Top Plants, the table of contents blurb about Duke’s Oconee plant, or a sentence in the cover story about that plant. In the interest of brevity, it seems we […]

By taking a waste product and converting it into a fuel source, the 6.5-MW Coca-Cola/Mas Energy Facility became the first U.S. operational trigeneration project fueled by landfill gas. Since March, the new system has provided electricity, steam, and chilled water to the adjacent Coca-Cola Syrup Plant, satisfying most of the plant’s energy requirements and reducing its long-term energy costs.

A convergence of new environmental regulations and practical realities is creating a boatload of challenges for power producers.

Set up by the Gujarat government, the Gujarat Solar Park is actually a group of solar parks that provide dedicated common infrastructure for photovoltaic-powered projects owned and operated by numerous individual companies. When construction at all the parks is completed by the end of 2013, the Gujarat Solar Park is projected to reach a combined capacity of almost 1,000 MW, which will make it the world’s largest solar energy generation installation.

The Stillwater hybrid facility is the world’s first renewable energy project that pairs geothermal power’s baseload generation capacity with solar power’s peak capacity. Inaugurated in May, the 26-MW solar plant is integrated with the adjacent 33-MW geothermal plant, which began operations in 2009, and provides energy to run the geothermal plant’s auxiliary loads.

Renewable energy projects installed on potentially contaminated lands, landfills, and mine sites have increased by 40% since 2008, a new list released last week by the Environmental Protection Agency (EPA) shows. Solar photovoltaic (PV) systems make up the bulk of about 184.7 MW installed at 60 sites in 25 U.S. states.

The bill for German Chancellor Angela Merkel’s coalition government’s knee-jerk decision to close all 17 of its nuclear plants by 2022 is coming due. Merkel’s energy plan is to radically expand the use of renewable energy to 35% of total power consumption by 2020 and to 80% by 2050. Currently, renewables represent 20% of the country’s energy mix.

On June 15, in response to a court order, the U.S. Environmental Protection Agency (EPA) proposed new lower limits on particulate matter (PM) emissions that are scheduled for release in mid-December, although that deadline may be missed. Even with implementation delays, now is a good time to start paying closer attention to the requirements of the proposed standard.

No other country has been as frequently cited as an example of exploiting the virtues of a nuclear-heavy energy policy as France. Deriving more than 75% of its electricity from 58 operational nuclear reactors with a total capacity of about 63 GW, France has one of the lowest costs of generation and is the world’s largest net exporter of power, earning €3 billion ($3.9 billion) a year from sales of surplus power to buyers beyond its borders. But that is all about to change.

The fundamental design principles and process for modern steam desuperheating, or the attemperation of superheated steam in the power generation industry, have been evolving since the early 1930s. Meeting the requirement for steam quantity, quality, and temperature consistency is the foundation of traditional attemperator component design, particularly for fast-response combined cycle plants.

The back-to-back collapse at the end of July of India’s Northern, Eastern, and Northeastern grids that slashed power to more than 60% of India’s population of 1.24 billion has impelled the country into a spending frenzy to upgrade its rickety power network, which, a government inquiry revealed, was one cause of the unprecedented blackouts.
