Because refractory is out of sight inside the gas flow path of a steam generator and its auxiliaries, it’s also often out of mind. That is, until the refractory fails and causes a forced outage.

Fire protection systems for air-cooled hydroelectric generators have several special requirements due to these generators’ unique geometries. This survey of options will help plant owners and operators make the best equipment selections for their plants and thereby avoid unexpected surprises.

Efficient boiler operation requires boiler auxiliary equipment to operate in harmony. In this third and last installment of our Power 101 series, we examine ways to decrease the auxiliary power requirements of boiler auxiliaries.

Two years ago, Spain’s fixation on renewables and “green jobs” was praised by President Obama as a success story worthy of our emulation. How is Spain doing today?

Excitement over an expected nuclear renaissance reached fever pitch over the past decade. Today, the original volume of announced projects has been sifted, leaving just a few serious ones that may match well with the level of loan guarantees recently announced as part of the president’s budget proposal. The pace of progress is slow, yet progress is almost certainly unavoidable.

In an anti-climactic markup that featured little new debate and no amendments by opposing Democrats, the House Energy and Power Subcommittee approved Republican legislation to block Obama administration action on climate change by stripping the Environmental Protection Agency of its Clean Air Act authority to regulate carbon dioxide and other greenhouse gases.

As POWER closes this issue (March 15), 6,000 people have been confirmed dead and 10,000 others are still missing as a result of the magnitude 9.0 earthquake and ensuing tsunami that destroyed Japan’s eastern shore on March 11. At this writing, the country is battling a third cataclysm—the potential meltdown of several reactors at Tokyo Electric Power Co. (TEPCO’s) Daiichi nuclear power plant in Fukushima Prefecture.

Part II of this three-part series moves up the typical utility organization to consider important fleet-level fossil plant operating metrics. This portion of the EUCG-sponsored benchmarking survey found that utilities favor fleet-level metrics that are similar to plant-level metrics but assign them different priority. Utilities generally agreed on what were important metrics in the eight categories examined, although none were favored by a majority of the surveyed utilities.

In an unusual ultimatum, the Environmental Protection Agency said that it is proposing to take over visibility portions of the Oklahoma Clean Air Act implementation plan to require three coal-fired power plants in the state either to switch to natural gas or install sulfur dioxide scrubbers within three years.

Five new nuclear reactors were connected to the grid while construction of 14 others began in 2010, the International Atomic Energy Agency (IAEA) reported in early March. Around the world, a total 65 reactors with a net power capacity of 62.9 GW were in various stages of construction—almost half of them in China.

Tendeka’s advanced monitoring solutions arm, Sensornet, introduced its FireLaser linear heat-detection system, which has been specifically designed for fire hazard detection applications. The FireLaser connects to a fiber-optic cable and determines temperature and distance data at thousands of points along its length. The fiber-optic cable is installed within the asset to be protected, acting as the […]

Anticipated clean air regulations could force the retirement of as much as 19,000 MW of coal capacity in the Mid-Atlantic—or 11% of the region’s generation—unless power prices rise to levels that make operation of the plants profitable, according to the independent market monitor for PJM Interconnection.

Geologists drilling an exploratory well in Iceland’s Krafla volcano in search of supercritical geothermal resources in 2009 unexpectedly uncovered a new way to harness energy from deep within Earth’s crust. It involves accessing shallow bodies of molten rock, which the geologists say could likely be found elsewhere in Iceland and around the world, wherever young volcanic rocks occur.

Aberdeen, UK–based casing and completion technology specialist Deep Casing Tools launched the Turbocaser Express, what it calls the “first ever drill-through tool to ensure casing to target depth, allowing wells to be drilled as planned and enhancing integrity.” After reaming a casing to target depth, the Turbocaser Express has a unique, patented internal design that […]

The "Regulations from the Executive in Need of Scrutiny" Act could put the kibosh on the EPA’s greenhouse gas regulatory surge.

Bayer in February brought online a pilot plant at Chempark Leverkusen, Germany, to recycle carbon dioxide (CO₂) scrubbed from the flue gas of a 1,000-MW RWE lignite-fired unit and convert it into a raw material and petroleum substitute for plastic manufacturing. The Bayer facility (Figure 4) essentially produces a chemical precursor into which CO₂ is incorporated and then processed into polyurethanes that are used for many everyday items.

Palmer Wahl Instruments Inc. has introduced a new line of digital pressure test gauges that includes the Palmer 3PC Auto Ranging Digital Pressure Test Gauge (shown here), which spans a pressure range of vacuum to 3,000 psi. Featuring an accuracy of 0.1%, and with the capacity to read nine different units of measure, the 3PC […]

Rules proposed by the Environmental Protection Agency (EPA) under Section 316(b) of the Clean Water Act on Monday call for flexible technology standards, determined on a case-by-case basis, for more than 670 power plants across the nation that pull in at least 2 million gallons per day of cooling water. The EPA said the proposal, which seeks to protect aquatic life, establishes a “common sense framework, putting a premium on public input and flexibility.”

The Senate is expected to vote on Thursday on an amendment introduced by Senate Republican Leader Mitch McConnell (R-Ky.) to small business legislation that could permanently block the Environmental Protection Agency (EPA) from promulgating climate change rules.

Nearly 20 Senate Democrats asked President Obama in a letter today not to agree to spending plans passed by the GOP-controlled House last month that would block funding for the Environmental Protection Agency’s (EPA’s) implementation of greenhouse gas rules.

As chief executives of 34 renewable energy companies urged congressional Republican and Democratic leaders to support the Department of Energy’s loan guarantee program, a study released by the Bipartisan Policy Center (BPC) suggests grants are a simpler and more effective way to help finance projects than tax credits.

With geothermal power being produced in nine states—and with 123 projects across 15 states under development—the U.S. leads the world in geothermal energy production, a new report from the Geothermal Energy Association (GEA) shows.

The Department of the Interior (DOI) and the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) on Thursday said they had begun a process to offer Bluewater Wind Delaware the first commercial wind lease off the coast of Delaware under the “Smart from the Start” Atlantic Offshore Wind program.

California’s Assembly on Tuesday passed a renewable energy mandate that would require the state’s power companies to generate 33%—up from the current 20%—of their power from renewable sources by 2020. The mandate is the most ambitious in the U.S.

The Nuclear Regulatory Commission (NRC) last week completed a Final Supplemental Environmental Impact Statement (FSEIS) for a limited work authorization (LWA) and the combined construction and operating licenses (COLs) for Southern Co.’s Vogtle Units 3 and 4 proposed for construction near Waynesboro, Ga.

Incidents unfolding at the quake-stricken Fukushima Daiichi reactors in Japan has led governments to take extraordinary safety measures around the world. Last week, European Union (EU) ministers agreed to re-check the safety of Europe’s 143 reactors, and in the U.S., regulators are expected to conduct seismic assessments on 27 reactors at 17 plants.

Sept. 30, 2011, is the revised final deadline for reporting 2010 data under the Environmental Protection Agency’s (EPA’s) Greenhouse Gas (GHG) Reporting Program. The agency also last week delayed the release of proposed rules that would govern cooling water intake systems at nuclear and coal plants until March 28.

A week after a U.S. House committee passed a bill sponsored by Rep. Fred Upton (R-Mich.) in the House and Sen. James Inhofe (R-Okla.) in the Senate, Sens. Inhofe and Sen. Mike Johanns (R-Neb.) introduced a bill that would require an interagency federal panel to undertake a “cumulative economic analysis” of Environmental Protection Agency (EPA) regulations.

Interior Secretary Ken Salazar on Tuesday said the Bureau of Land Management (BLM) would hold four competitive lease sales from May through August for Powder River Basin coal tracts in Wyoming. The tracts, covering 7,441.25 acres, hold an estimated 758 million tons of low-sulfur coal.

AC power is now available at Units 1, 2, and 4 of the six-reactor quake- and tsunami-hit Fukushima Daiichi nuclear plant in Japan, according to recent updates; however, the International Atomic Energy Agency (IAEA) still believes “the overall situation remains of serious concern.”
