Common fuel-handling problems in the power industry often result in production downtime, costing the owner perhaps up to $200,000 per hour. There are many areas within a coal-fired power plant where mishaps can cause stoppage of material flow. Here we discuss how to select the best switch technology to reduce the possibility of coal flow stoppages.

WTE technologies offer cost-effective, near-term solutions for producing baseload electric power, meeting renewable energy targets, and reducing greenhouse gas emissions in the U.S. and other countries. They also present opportunities for improving resource management practices, increasing energy security, enhancing environmental quality, and supporting climate policy goals around the world.

The impact of recently released air emissions regulations has stirred heated debate about forced coal plant closures and the possibility of reduced grid reliability in some regions. Biomass power may be an unexpected beneficiary of the new rules.

The first license to construct a new nuclear power plant in the U.S. in 34 years was granted by the Nuclear Regulatory Commission on Feb. 9. Has the elusive nuclear renaissance finally begun?

Optimizing combustion control is critical to reducing emissions and increasing plant operating efficiency, particularly for fluidized bed combustion (FBC) boiler plants burning biomass fuel that has unpredictable moisture content. The secret: measuring actual energy flow.

Growing concern about water usage by U.S. electric power generation is being prompted by a number of factors, including projected increases in power demand due to population growth, competing uses for water, and recent drought conditions in various parts of the country. Our overview presents diverse perspectives from industry experts about current and future challenges of balancing power generation needs with declining water availability.

Gone are the days when ocean or river water for once-through cooling of a new power plant was assumed to be available. Today, more than 500 fossil-fueled and 38 nuclear plants use once-through cooling. However, regulators in several states are aggressively pushing what is essentially a ban on the use of once-through water cooling, forcing a conversion to closed-cycle cooling.

In the year following the Fukushima accident in Japan, the nuclear sector has seen several setbacks (text in orange) as well as major milestones (white).

Tempil introduced BLOXIDE°, a rust-preventive weldable primer that provides protection from rust formation on edges prepared for welding. It also acts as an oxygen/oxide scavenger in the weld pool. This results in a clean X-ray quality weld. Steel sections having their prepared edges coated with BLOXIDE° can be stored outside in open yards for extended […]

Following key regulatory approvals in the UK and U.S. of Westinghouse’s AP1000 and AREVA’s EPR Generation III+ reactor designs, France’s nuclear safety authority in February determined that the little-known ATMEA 1 reactor design met international safety criteria for Generation III+ reactors. The reactor is a 1,100-MW pressurized water reactor (PWR) developed and marketed by ATMEA, a 2007-created joint venture between France’s AREVA and Japan’s Mitsubishi Heavy Industries (MHI).

Multi-disciplined engineering and consulting firm ENERCON received patents for a filter medium for strainers used in nuclear reactor emergency core cooling systems (ECCS). ENERCON’s Debris Bypass Eliminator was developed in response to the Nuclear Regulatory Commission’s Generic Safety Issue, GSI-191, “Assessment of Debris Accumulation on PWR Sump Performance.” During long-term recirculation for cooling of the […]

Southern California Edison (SCE), operator of the San Onofre Nuclear Generating Station near San Clemente, Calif., must understand and address unusual wear on steam generator tubes before it can be allowed to restart the beleaguered two-reactor nuclear plant, the Nuclear Regulatory Commission (NRC) said on Tuesday. California officials are meanwhile preparing contingency plans to prevent power outages this summer that could result from the plant’s indefinite shutdown.

The Nuclear Regulatory Commission (NRC) will decide on Friday whether to award a combined construction and operation license (COL) to SCANA Corp.’s proposed project for two 1,117-MW reactors at the site of the V.C. Summer Nuclear Station near Jenkinsville, S.C. If the SCANA Corp. project receives the NRC’s approval, it will be the second project in nearly 30 years to receive such approval.

Official notifications to regional reliability organizations PJM Interconnection and Southwest Power Pool (SPP) made last week by American Electric Power (AEP) show that the company will retire about 4,600 MW of coal-fired capacity to comply with a series of Environmental Protection Agency (EPA) rules. The plan differs markedly from the 6,000 MW of anticipated retirements AEP announced in June 2011.

Bulgaria on Wednesday definitively abandoned plans to build the Belene nuclear plant based on Russian technology, saying it would instead build a gas-fired power plant on the Danube River site. Bulgarian Prime Minister Boyko Borisov cited soaring costs as well as a failure to find Western partners for the projects after German company RWE withdrew from the project in 2009.

Two natural gas–fired projects received key approvals from state regulators this week. The Florida Public Service Commission on Tuesday approved Florida Power & Light’s (FPL’s) proposed 1,277-MW gas unit for Broward County, Fla., and Louisiana’s Public Service Commission approved Entergy’s 550-MW gas project for Jefferson County, La.

Pushing for an “all-out, all-of-the-above” energy strategy, the Obama administration last week announced new funding to advance the development of small modular reactors (SMRs) in the U.S.

The Environmental Protection Agency (EPA) on Tuesday proposed its first-ever carbon pollution standard for new power plants, limiting carbon dioxide (CO₂) emissions from new fossil fuel-fired power plants to 1,000 pounds/MWh. The standard is achievable for new natural gas combined cycle units without add-on controls, but it would force new coal or petroleum coke units to install carbon capture and storage (CCS) technology, which is currently commercially unavailable, the agency acknowledged.

By Kennedy Maize Washington, D.C., 28 March 2012 — Just how significant is the Obama administration’s new regulation on carbon dioxide emissions from new coal-fired power plants, announced yesterday? From here, it looks like a fair amount of ado about not very much. In today’s cynical political environment, it’s hard not to see the Environmental […]

What killed global warming as the president’s number one priority?

Freedom, opportunity, prosperity, and a civil society have made America exceptional. But without energy—secure and affordable energy—many of our great accomplishments would not have been possible.

FirstEnergy Corp., AEP, and GenOn have all announced coal-fired plant closures, totaling over 13 GW, caused by the recently finalized Mercury and Air Toxics Standards.

A proposed rule issued in late February by the Environmental Protection Agency (EPA) will not change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs. However, it includes revisions to the permitting program that would provide some flexibility in how compliance is achieved with GHG emission caps.

A new report released in early March by the North American Electric Reliability Corp. (NERC) found that loss of reactive power was the most likely outcome from a severe solar storm that was centered over North America. Significant losses of reactive power could lead to voltage instability, and, if not identified and managed appropriately, power system voltage collapse could occur, the report concludes.

It has been said that a picture is worth a thousand words. However, photos of the conflagrations that have resulted from ignition of minor lube oil leaks on a typical steam turbine room floor will leave you speechless. Full-scale physical simulations of oil fires by the insurance company FM Global leave no doubt that power plant fire prevention and mitigation is a judicious blend of art and science.

This unconventional technique for removing slag from solid fuel-fired boilers, used for more than two decades, has exploded in popularity. But the risks are very real, and not all blasters are created equal.

Moving into the election season, President Obama has again pointed to the number of green jobs supposedly created by his administration in a recent campaign advertisement, although the claims are not supported by available data. Now, other government authorities are using the same poor data as an excuse to increase spending.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In Part I of a three-part report, we introduce the A-USC boiler. Future reports will discuss the metallurgical and boiler design challenges.

After concluding that the Chinese government provided illegal subsidies to domestic solar panel makers, the U.S. Commerce Department on Tuesday said it would impose countervailing duties on the imports of Chinese crystalline silicon photovoltaic (PV) cells and modules. But the tariffs were smaller than some solar companies had petitioned for, ranging at 2.9% to 4.73%, depending on which company manufactured them.
