If engineered well and drained properly, a simple finned-tube heat exchanger can help maximize a fossil-fueled power plant’s combustion efficiency, capacity, and air pollution reduction. Use the guidelines in this…
—Dr. Robert Peltier, PE Editor-in-Chief The hot hand in coal-fired power plant development is undoubtedly held by Nevada. In a departure from Sin City's latest marketing slogan, "What happens…
The U.S. needs new generating capacity in coming decades to meet growing electricity demand. The increasing scarcity of land within utility load centers, combined with environmental opposition to the siting…
Age is wreaking havoc on the U.S. generation industry, especially the coal-fired sector. Industry conferences are replete with hand-wringing over the "brain drain," the lack of skilled personnel, the meager…
Last year, the U.S. wind energy industry easily broke its record for new installed capacity. According to the Washington-based American Wind Energy Association (AWEA), nearly 2,500 MW of wind turbines…
By regenerating the catalyst of its selective catalytic reduction (SCR) system instead of purchasing a new one, the typical 500-MW coal-fired power plant can save about $500,000 to $1,000,000 annually.…
MECHANICAL CFB refractory repair Refractory, the heat-resistant materials that line the inside of most furnaces, are an important component of any steam generator because they protect expensive and vital parts…
Enforcement and (re)interpretation of the Clean Air Act's new source review (NSR) rules will likely come into focus later this year as many of the key lawsuits against electric utilities…
A few years ago, skyrocketing energy costs and tighter emissions limits prompted officials at the Wastewater Treatment Division of King County's Department of Natural Resources and Parks in Washington State…
