A new modular and durable quick-release mount for popular fire-extinguisher sizes is now available from Off-Road Solutions (ORS). The system uses two pieces of 6061-T6 billet aluminum: one attaches to the extinguisher while the other piece secures to a fixed object. The 3/16-inch hinge pin and 3/8-inch quick-release pull pin with detent ball are made […]

Construction of a $310 million repository about 250 meters below Earth’s surface for low- and intermediate-level radioactive waste from the operation and future decommissioning of Hungary’s power plants reached a significant milestone at Bataapati.

Filtersense’s new continuous particulate emissions monitor and baghouse leak detector incorporates “Automatic Zero and Span Checks” to eliminate manual calibration audits, as required by the U.S. Environmental Protection Agency (EPA) for Maximum Achievable Control Technology (MACT) standards and other regulations for fabric filter particulate emissions monitoring. In addition to internal self-checks, the company’s field-proven induction-sensing […]

Here are some of the longest pipelines recently built as well as noteworthy ones in the pipeline.

ATCO Emissions Management (ATCO) announced the addition of heat recovery steam generators (HRSGs) to its line of gas turbine auxiliary equipment for the power, oil, gas, and cogeneration markets. The new HRSG product, an energy recovery heat exchanger that recovers heat from a hot gas stream, will initially serve facilities with gas turbines up to […]

Feedwater heaters are used to preheat boiler feedwater by condensing steam extracted from several stages of the steam turbine. Feedwater heaters enhance the thermal efficiency of the power plant by reducing the amount of fuel burned in the boiler to produce a specified power. At the same time, the steam energy extracted from the turbine by the feedwater heater helps to reduce the rate of energy rejection to the environment via the condenser.

Most professionals in the energy industry know about biomass; fewer of us are conversant with biogas. This commentary explains the basics of biogas, with a focus on its current use and future potential as a source of electrical power.

Japan’s scramble to replace generation lost from nuclear power plants that were shuttered after the March 2011 Fukushima Daiichi nuclear accident has forced it to rely on pricey imports of fossil fuels—and soaring energy costs are hammering the world’s third-largest economy.

More and more electricity is generated by natural gas. This trend is likely to persist. Hydraulic fracturing technology is increasing domestic supplies and enabling natural gas prices to remain at historic lows.

A pervasive drought in northeast Brazil has dried up power supplies from the region’s hydropower facilities, making the area prone to blackouts and crippling economic growth in one of the country’s emerging agricultural havens.

The use of low-grade coal is becoming synonymous with circulating fluidized bed (CFB) power plants. Although CFB technology may often be a better choice than pulverized coal technology, that is not always the case. Owners and developers need to consider several technical and economic factors before making this decision.

Selected business news and deals in the power generation industry.

Covanta Energy and the City and County of Honolulu recently completed a $300 million expansion of a 20-year-old waste-to-energy (WTE) facility. The plant is now capable of processing up to 3,000 tons of municipal refuse daily, recycling all the metals, and generating up to 90 MW—enough to supply nearly 10% of Oahu’s electricity.

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the 16th and 17th chapters, “Uranium Rush and the New ’49ers” and “Naked Shorts at Westinghouse,” the first two chapters of the “False Scarcity and Fools for Fuels” section.

You may be surprised to learn that even with the increased demand for biomass fuels for power generation, construction and demolition fuel is classified as solid waste, not biomass. Reconsidering this designation is critical as U.S. environmental regulations tighten emission profiles for solid waste combustion units and renewable portfolio standards expand.

The lifeblood of the combined cycle plant is its water chemistry program. This is particularly true for plants designed for high pressures and temperatures as well as fast starts and cycling. Even though such plants are increasingly common, no universal chemistry program can be used for all of them.

Controversy concerning natural gas exports flared the day the U.S. Energy Information Administration (EIA) released its estimate that U.S. natural gas exports could begin in 2021.

Recent reports by the National Renewable Energy Laboratory and others suggest that the emissions-reducing benefits of renewable energy sources such as wind and solar may have been overstated and the cost of cycling fossil-fueled plants underestimated. These findings may change how utilities and policymakers weigh the costs and benefits of wind and solar energy.

Mercury emissions from power plants in 137 United Nations member countries could be subject to strict controls and reductions if an international treaty is signed by participating nations this October.

Steam turbine blade cracking often suggests the need for an upgraded blade design. Follow the process of reversing engineering a failed blade to produce a more reliable and efficient design.

Technological progress and policy interventions over the last decade have arguably enhanced U.S. energy security and put it in a stronger position to shape its own energy destiny, a new report from the Bipartisan Policy Center (BPC) argues. Among more than 50 energy policy recommendations outlined in the report to tackle significant challenges still faced by the nation’s energy sector are those calling for the establishment of a comprehensive national energy strategy.

A rule proposed by the Environmental Protection Agency (EPA) directs 36 states to revise their Clean Air Act State Implementation Plans (SIPs) to eliminate exemptions for excess emissions of air pollutants at power plants during startup, shutdown, or when the plant malfunctions.

The Department of Energy (DOE) last week announced the availability of up to $20 million for the development of tools and technologies to enhance cybersecurity of delivery control systems for electricity, oil, and gas in the U.S.

A modified settlement reached between American Electric Power (AEP), a coalition of citizen groups, and the Environmental Protection Agency (EPA) on Monday will allow the utility to install less expensive pollution controls on a coal-fired power plant if it ceases coal combustion by 2015 at three aging power plants in Indiana, Ohio, and Kentucky.

A 20-MW facility in Ford Heights, Ill., that burns waste tires to produce power is to be shut down to resolve allegations by the Environmental Protection Agency (EPA) of Clean Air Act violations.

Dr. Steven Chu gave what was likely his last public speech as U.S. secretary of energy today on the last day of the ARPA-E Energy Innovation Summit. As usual for Chu presentations, it was a mix of data, vision, and humor. It fell to others to comment on the value and legacy of his service, especially to energy research and development.

Southern California Edison now expects the Nuclear Regulatory Commission to decide in late April or May whether or not the 2,300-MW San Onofre Nuclear Generating Station (SONGS) Units 2 and 3 may restart in time for this summer’s demand season.

The Advanced Research Projects Agency-Energy (ARPA-E) may be the most important federal agency many in the power industry have never heard of. Whatever generation technology you are associated with, ARPA-E’s work will affect its future.

By Kennedy Maize Washington, D.C., February 23, 2013 — Will Chicago Bridge & Iron Co. buy nuclear reactor vendor Westinghouse Electric Co.? That rumor was flying at the Platts nuclear conference in Washington this week. There is a certain, slightly perverse logic to such a deal. CB&I closed its $3 billion acquisition of Shaw Group […]

By Kennedy Maize Washington, D.C., February 22, 2013 – How many new nuclear reactors are under construction in the world today? That seems like a straightforward question with an easy answer. Wrong. It’s a figure that defies precision. Ask Tom Nauman, a veteran of the Shaw Group, which became a part of CB&I (nee Chicago […]
