With the U.S. economy currently in a free fall, some utility industry leaders and elected officials argue that carbon cap legislation should be put on hold while the country recovers financially. However, President Barack Obama has a different game plan.

Once a Soviet satellite, Poland is now transforming into a thoroughly modern nation. To support its growing economy, this recent European Union member country is modernizing its power industry. Exemplifying the advances in the Polish electricity generation market is the 460-MW Patnów II Power Plant — the largest, most efficient (supercritical cycle), and environmentally cleanest lignite-fired unit in the country.

Purge water from a typical wet flue gas desulfurization system contains myriad chemical constituents and heavy metals whose mixture is determined by the fuel source and combustion products as well as the stack gas treatment process. A well-designed water treatment system can tolerate upstream fuel and sorbent variation over time and consists of multiple process treatment steps arranged in just the right order to produce wastewater acceptable for discharge.

Formed suction intake designs have been used in many large vertical pump stations in flood control projects. Space limitations at the Oak Creek Power Plant Expansion Project near Milwaukee, Wisconsin, created a unique opportunity to apply this technology to an 800,000-gpm cooling water system upgrade for the entire Oak Creek Power Plant.

Barely a month after the U.S. Federal Energy Regulatory Commission (FERC) licensed the nation’s first commercial hydrokinetic power station, Houston-based Hydro Green Energy in January completed installation of the first of two turbines at an existing run-of-river hydropower plant on the Mississippi River for the Minnesota city of Hastings. When the second turbine is installed later this spring, the two hydrokinetic turbines will constitute a floating array that will sit on top of a barge at the Army Corps of Engineers’ Lock & Dam No. 2.

Tuning power plant controls takes nerves of steel and an intimate knowledge of plant systems gained only by experience. Tuning controls also requires equal parts art and science, which probably is why there are so few tuning experts in the power industry. In Part I of a two-part series, we explore a mix of the theoretical and practical aspects of tuning boiler controls.

Like the airline industry, power generators all over the world have been seeking alternative fuels with which to produce electricity, and the blends are bound to get stranger. One company is looking to make liquid fuels from chicken fat, beef tallow, and pork lard, for example. Here’s a list of innovative fuels that generators could use in the near future.

Pulverizer throughput is determined by the coal fineness desired for a given coal. However, compromising on coal fineness when your pulverizer isn’t up to snuff can increase NO _x and cause many furnace problems. Your least costly option for increasing pulverizer capacity is to pay careful attention to key dimensions and critical tolerances during your next overhaul.

Solar panel prices have taken a 10% tumble since October last year, and they are expected to drop another 15% to 20% this year, owning to an oversupply from the mass of new factories and draining demand in Germany and Spain, where solar incentives were recently cut. In the U.S., the low prices — pushed even lower by the renewed solar tax credits that took effect on Jan. 1 and other incentives — have heightened demand, both on the distributed generation level and at utility scale.

POWER published a summary of the flue gas desulfurization system scrubber cost survey conducted by the EUCG’s Fossil Productivity Committee in our July 2007 issue. Although the detailed results of the latest survey are proprietary to EUCG members that participated in it, we are privileged to present the newest summary data. The bottom line: Costs continue to rise but appear to be more predictable.

By Kennedy Maize Princeton physicist Will Happer, a prominent skeptic about man-made global warming, told the Senate Environment and Public Works Committee Feb. 25 that the earth is in a “CO2 famine,” and more atmospheric carbon dioxide would be a very good thing indeed. “Almost never have CO2 levels been as low” as in the […]

A year after a U.S. appeals court vacated a Clean Air Act Rule that would have allowed a cap-and-trade approach for mercury emitted by power plants, the nation’s highest court on Monday declined to hear arguments on the case.

A federal court on Tuesday sided with 13 states that had challenged the U.S. Environment Protection Agency’s (EPA) annual air quality standard for microscopic pollutants known as particulate matter or soot, ruling that the government’s standards were “unsupported” by “reasoned decision-making.”

A federal appeals court last week slapped the Federal Energy Regulatory Commission (FERC) on the hand for overreaching the authority granted to the agency by the Energy Policy Act of 2005 when it took an “expansive interpretation” of the law in asserting its power to override state decisions.

U.S. Energy Secretary Steven Chu last week announced a sweeping reorganization of the Department of Energy’s (DOE) dispersal of direct loans, loan guarantees, and funding contained in the American Recovery and Reinvestment Act.

If the Obama administration regulates carbon dioxide, future costs to contain or abate emissions at the 600-MW John W. Turk Jr. Power Plant proposed for southwest Arkansas by the Southwestern Electric Power Co. (SWEPCO) could exceed $163 million a year—or more than $2.8 billion for the 40-year life of the plant—says an economic study prepared for two environmental groups.

The U.S. government has sued Louisiana Generating, alleging that the NRG Energy subsidiary violated the clean air rules by operating the Big Cajun 2 Power Plant without also installing and operating modern pollution control equipment after the generating units had undergone major “modifications.”
