Tier 4 has become the talk of the industry and with good reason. Engine and machine manufacturers alike have made design changes to their product offerings to meet the standards set in place by the Environmental Protection Agency (EPA).
The strongest earthquake ever recorded in Japan at a magnitude of 9.0 struck the country on March 11. Below is a timeline of events following the earthquake and tsunami and the effect on nuclear power plants in Japan. An up-to-date timeline, plus ongoing nuclear industry coverage.
Power generation capacity in Canada is on the rise thanks to government and other incentive programs, such as Ontario’s feed-in tariff program. The increase in generation helped the country reach a renewable energy goal of 4,000 MW of new installed capacity in 2010, a year ahead of schedule.
Sulfur dioxide (SO2) emissions have long been an area of concern for the U.S. Environmental Protection Agency (EPA) and power producers. A number of regulations are currently targeting or soon are set to target SO2 emissions, including the Clean Air Transport Rule (CATR) and the SO2 National Ambient Air Quality Standards (NAAQS).
With the projected rapid growth in flue gas scrubber construction, plant personnel at facilities where wet flue gas desulfurization (WFGD) is selected will be tasked with choosing the proper reagent for the system. In some cases, this may involve a choice between selecting a reagent of high quality, with potentially high transportation costs versus a lower quality material located closer to the plant.
When the U.S. commercial nuclear power industry took flight over 50 years ago, many skilled workers selected it as their career. But with an average worker’s age now in the mid-50s, it is no secret that a large portion of the workforce in the United States nuclear power industry is approaching retirement.
In a perfect world, the fire alarm control panel (FACP) would be a system that only required attention during premeditated events such as a valve being closed off for system maintenance or for inspection and testing purposes. The alarm systems that control a power generating plant’s fire protection systems can be confusing to the personnel who do not routinely operate and maintain them.
The most-up-to date discussions of what is happening in the coal-fired power generation industry will take place when the 11th annual Coal-Gen conference and exhibition gets underway in Columbus, Ohio beginning August 17th and running through August 19th.
One question I often am asked is, “How tall should the exhaust stack be?” It’s a seemingly simple question, but the only way to get an exact answer is to run an air dispersion model.
The Ameresco-owned and operated landfill gas-to-energy plant in Jefferson City, Mo. has been providing power to the central region of the state since April 2009. The 3.2 MW plant uses three GE Jenbacher engines, each equipped with a 1,060 kW generator and heat recovery steam generators to capture excess heat to provide steam and hot water for two state-owner correctional centers, cutting the state’s power bill while helping meet renewable energy goals.
Power plants are designed to operate for decades, provided they undergo regular repair, upgrade and improvement. Much of the time, those maintenance actions are minor. But plant managers expect a few big-ticket expenditures.
U.S. wind energy production over the next 30 to 50 years will largely be unaffected by upward changes in global temperature, say a pair of Indiana University Bloomington scientists who analyzed output from several regional climate models to assess future wind patterns in America’s lower 48 states.
The emergence of utility-scale photovoltaics was clearly a highlight of the renewable energy industry in 2010. The popularity of state and utility renewable portfolio standards (RPS), the federal investment tax credit (ITC) and the post-recession emergence of financial institutions with suitable tax appetites, all combined to create an environment where solar project developers and their equity and debt partners could complete deals.
Natural disasters may not happen with any more frequency, but the ubiquitous nature of communication means that few people in the industrialized world are unaware when one strikes.
Nuclear power safety is still making news headlines as Japan’s crisis continues to unfold. Yes, the situation there is very serious and a review of nuclear power plants is the next move to make, as is being done in the United States.
Joining Technologies Inc. introduces its latest innovation, the Infinite Web 355 all-in-one coil joiner, a laser cutting and welding system for splicing iron and nickel-based strip alloys. The all-in-one design incorporates laser welding and cutting with a single head.
