Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work. Determining the design changes required in the valve and fluid system to prevent the vibration from occurring requires advanced analytical techniques.

Citing newly finalized and proposed environmental regulations that could make costs uncertain, FirstEnergy Corp. on Thursday said it would shutter six older coal-fired power plants with capacities totaling 2,689 MW in Ohio, Pennsylvania, and Maryland by September. The same uncertainties prompted a major backer of a $2 billion coal-fired power plant planned for Washington County in Georgia to pull its funding.

With the 2012 election year upon us, it promises to be an interesting time for energy politics and policy. Here are 12 (really 13 because of some creative headline writing) issues that will keep the sector hopping this year.

Last December, as Spain’s national carbon capture and storage (CCS) research laboratory Fundación Ciudad de la Energía (CIUDEN) began a much-watched testing phase of oxycombustion in its 30-MWth circulating fluidized bed (CFB) boiler in Cubillos del Sil, Vattenfall scrapped the €1.5 billion ($2 billion) Jänschwalde CCS demonstration project that it had planned to build and begin operating by 2015 in the German federal state of Brandenburg.

Turner Designs has introduced the Opti-Check Handheld Fluorometer for performing system verifications for industrial water process control applications.

Indonesian state-owned utility Perusahaan Listrik Negara (PLN) formally launched operations at three new coal-fired power plants on Dec. 28.

Columbia Research Laboratories’s Model VM-300 is a general purpose vibration measuring instrument designed for periodic routine checks of industrial equipment where portability and ease of use are required. Acceleration, velocity, and displacement measurement modes are provided, along with a number of value-enhancing features. Dual power allows the VM-300 to be powered from its internal battery […]

A failed electrical insulator at a switchyard at Exelon Generation Co.’s two-unit Byron nuclear plant in Lisle, Ill., has been blamed for the loss of offsite power on Monday morning that automatically shut down Unit 2 and forced Exelon to declare an “Unusual Event.”

The U.S. Court of Appeals for the District of Columbia Circuit temporarily blocked the Cross-State Air Pollution Rule (CSAPR) just two days before it was set to go into effect. The federal court ordered the Environmental Protection Agency (EPA) to continue administering the previously promulgated Clean Air Interstate Rule (CAIR) until a final decision can be made on the merits of the rule, likely this summer or fall.

ANDRITZ to Rebuild Oldest Egyptian Nile Dam. Austrian firm ANDRITZ HYDRO on Dec. 22 won a $138.4 million contract from the Egyptian Ministries of Energy and Water Resources for the supply and installation of four bulb turbines, generators, and the electrical and hydro-mechanical equipment to rebuild the Assiut barrage—the oldest dam in the Egyptian section […]

Milan-based ATO S.r.l. has introduced a series of flexible seal rings made of KetaSpire polyetheretherketone (PEEK) resin, which is made by Solvay Specialty Polymers. KetaSpire KT-820 PEEK provides greater flexibility and elasticity than competitive PEEK grades, the company says. The parts can be folded or twisted in half and then twisted again into three or […]

The 15-member Blue Ribbon Commission (BRC) appointed by Energy Secretary Steven Chu in January 2010 to provide comprehensive recommendations for a long-term solution to managing and disposing the nation’s spent nuclear fuel and high-level radioactive waste released its much-anticipated final report last week.

The hazards of coal dust accumulation in power plants are familiar to coal-fired plant operators. Operators of plants that burn Powder River Basin coal are particularly aware of necessary housekeeping and fuel-handling practices, but any plant that allows excessive amounts of coal dust to accumulate is playing Russian Roulette with its staff and equipment.

The National Fire Protection Association has issued a new standard for gas line cleaning in response to the urgent recommendations prepared by the U.S. Chemical Safety Board.

French company ProSim, which provides process simulation and optimization software to the process industries, released a new version of BatchReactor, its software for batch chemical reactors simulation. The new software combines detailed equipment modeling, reaction engineering, and advanced numerical methods to create a state-of-the art simulation environment for chemists and chemical engineers, providing a complete […]

A federal district court judge on Tuesday ruled that the Rural Utilities Service (RUS), an arm of the U.S. Department of Agriculture (USDA), must complete an environmental impact study (EIS) before any approvals or other major federal action can be taken on the $2.8 billion expansion at Sunflower Electric Power Corp.’s coal plant in Holcombe, Kansas. The ruling may delay construction of the 875-MW plant, a politically controversial project in the Kansas Legislature.

Creating a landfill to hold dry boiler ash is a challenging proposition these days. There’s more to the project than you might imagine, as you’ll learn from this article about the development of a typical new ash landfill.

POWER recently talked with Erika Jakobsson, a project manager at Volvo Technology in Gothenburg, Sweden, who is responsible for developing intelligent trucks in response to European Union (EU) directives.

The Precision Controls Division of Marsh Bellofram Corp. launched the Type 41 high-performance air pressure regulator series, which is designed to support a variety of demanding industrial and original equipment manufacturer flow-monitoring requirements. Available in two different packages with identical performance characteristics, both with ¼-inch NPT BSPT port size, the Type 41 incorporates a patented […]

A high-voltage electricity panel arc reportedly sparked a brief fire at the 100-MW Nacogdoches Power, LLC biomass power plant under construction in Sacul, Texas, and sent two workers to hospital in critical condition on Tuesday.

The expectation of millions of "green jobs" has disappeared from public debate. Today, the debate is narrowly focused on "jobs" and selecting the best approach to developing permanent jobs, regardless of color. Some look to the government to create jobs through regulation or subsidy, and others trust companies operating under free market principles to create permanent jobs.

Synovus relies on emergency standby generator sets to prevent any loss of services or data in the event of a utility outage.

Silicon Designs, a designer and manufacturer of rugged industrial-grade microelectromechanical systems (MEMS) capacitive accelerometer chips and modules, has introduced a ±5 g model to its 2210 accelerometer series.

Federal Energy Regulatory Commission (FERC) on Monday released a white paper that seeks comment on its proposals to “provide a fair, timely and transparent process” for FERC to advise the Environmental Protection Agency (EPA) on requests for extension of time to comply with its Mercury and Air Toxics Standards rule.

Rules requiring removal of combustible dust from the workplace will undoubtedly improve worker safety and health. A survey of equipment suppliers finds a variety of dust collection systems are available to meet just about every dust collection need in the power house.

The U.S. Environmental Protection Agency’s (EPA’s) new Mercury and Air Toxics Standards (MATS) rule for power plants has critics’ tempers flaring. Not surprisingly, a number of electric power representatives, industry groups, and elected officials oppose the rule, which was released on Dec. 21, 2011.

The electric power generation system is the backbone of our economy. Recently, however, sudden outages or rolling blackouts have increased.

Handheld smart devices providing custom applications and Internet access at the touch of a virtual button are common today. Hidden beneath their touchscreens is a global network of digital technologies that respond to each command. Will these familiar commercial technologies and apps make their way to industrial digital control systems?
