The design of Nash’s new ECO-FLO builds on the company’s previous liquid ring vacuum pump models. While it offers the same reliability, performance, and operating costs, the ECO-FLO reduces water usage by up to 50%. The inlet and discharge piping are unchanged, and the upgraded model uses an existing base, motor, and drive. ECO-FLO is […]

In this column last month I quoted Indian Environmental Minister Jairam Ramesh to represent India’s intention to not agree to any legally binding emissions targets at the Copenhagen Climate Change Conference in December. That conference will start formal negotiations of a follow-on agreement to the Kyoto Protocol. A number of readers wrote to say that they believe India and China, despite their protestations to the contrary, will cave to international pressure and at the end of the day agree to some binding carbon emissions limits. I disagree.

For some time, the U.S. energy industry has feared the prospect of large-scale climate change litigation (CCL) that seeks to link emissions of greenhouse gases (GHG) to global warming. Thus far though, only a handful of such suits have been filed, and none has yielded any judgments against the energy industry. This begs the question of whether the energy industry can now stop worrying about CCL.

E.H. Wach’s newly launched Small Diameter Split Frame (SDSF) is an externally mounted machine tool for cutting, beveling, and counterboring pipe from 0.84 inch to 4.5 inch diameter. Featuring a self-squaring clamping system for precise cutting results that are typically available only with fixed machine tools, the SDSF is also capable of performing socket weld […]

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. […]

For several years there has been widespread doubt about Washington’s ability to move forward with a national program to address climate change and reduce greenhouse gas (GHG) emissions. At various times during the Bush administration, it appeared that legislation might be possible, but it always collapsed under the weight of partisan politics and competing special […]

When TVA’s Bull Run Fossil Plant was erected in the mid-1960s, it could boast of having the largest boiler in the U.S., and the plant has enjoyed a long, enviable efficiency track record. Today the public judges coal plants by their emissions. Now that it’s been outfitted with the most advanced air quality control systems, including the latest flue gas desulfurization system design, Bull Run scores a perfect "10" in both categories.

Hirakud Power uses environmentally friendly circulating fluidized bed (CFB) combustion technology to produce electricity for one of the world’s oldest aluminum-smelting operations. This "captive power plant" has engineered a number of technical fixes to its original boiler designs to improve plant reliability and reduce outages and boiler repair costs. It also has made strategic investments in upgraded machinery to reduce auxiliary power consumption. In addition to an excellent environmental track record, as evidenced by being Asia’s first ISO 14001 (BS 7750) – certified power plant, Hirakud Power has solidified its position as an industry leader in CFB boiler operating experience and efficient power production.

This plant’s staff proves that a can-do attitude and high productivity can be compatible with a safer workplace. The proactive approaches they used at the 162-MW Hutsonville plant ranged from improving boiler efficiency to better managing risks to workers.

Omaha Public Power District commissioned Unit 2 at its Nebraska City Station in May of this year. The new 682-MW unit joins Unit 1, which went commercial 30 years ago in the same month. The project is outfitted with all the requisite air quality control systems and sports a very good thermal efficiency. More importantly, the plant will provide reasonably priced power for customers of eight municipal utilities that share ownership of the plant’s electrical output. Those utilities paid for their portion of the construction cost and now receive a like portion of the electrical output from Unit 2 under a unique participation power agreement.

Hard work was required at the 2,600-MW Rockport Plant to make improvements to equipment, materials, and processes. But that hard work has paid off: The plant’s units operate much better, employee safety has improved, the facility is setting generation records with both of its 1,300-MW units, and it earned the PRB Coal Users’ Group Large Plant of the Year honors.

A reusable organic liquid developed by the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) to remove carbon dioxide (CO₂) or sulfur dioxide (SO₂) from power plant emissions could one day replace current scrubbing methods and allow power plants to capture the gases in a cost-efficient way that uses no water and less energy.

Complying with a corporate environmental policy requires much more than just writing a check for equipment upgrades. It takes a dedicated and knowledgeable staff that’s willing to invest years of work to permanently reduce a plant’s environmental footprint. The staff of Seminole Generating Station have completed multiple, incremental plant improvements over the past decade that have significantly reduced air emissions and minimized solid waste disposal.

Since Robert Stirling invented the Stirling engine in 1816, it has been used in an array of specialized applications. That trend continues today. Its compatibility with clean energy sources is becoming apparent: It is an external combustion engine that can utilize almost any heat source, it encloses a fixed amount of a gaseous working fluid, and it doesn’t require any water — unlike a steam engine.

Italy’s Enel said in August that it has successfully begun operating a power plant in Fusina, near Venice, in the Veneto region of Italy, that is fueled 100% by hydrogen. The industrial-sized plant’s building site was officially opened in April 2008, after which infrastructure and technology work was carried out on schedule. Initial testing of the turbine using methane gas was conducted in the spring of 2009, and now — after completion of the special pipeline — the plant has switched to 100% hydrogen fueling, Italy’s largest energy company said.

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 […]

In a decision that experts say could have profound implications on the future of climate change litigation, a two-judge panel of a federal appeals court on Monday reversed a 2005 district court decision and ruled that eight states and New York City can sue coal-burning utilities for creating a “public nuisance” through their emissions of climate-warming greenhouse gases.

The Environmental Protection Agency (EPA) on Tuesday issued a final rule that will require—for the first time—most large emitters of greenhouse gases to begin recording data under a new reporting system starting in 2010.
