  • Electric Vehicles: The Uncertain Road Ahead

    "Diversify, diversify, diversify." That has long been the mantra of many Wall Street pundits when advising investors on how to weather the risks of the stock market. Now advocates of electric vehicles (EVs) are using this same logic to champion plug-in hybrid electric vehicles (PHEVs).

  • Big Bend’s Multi-Unit SCR Retrofit

    Tampa Electric will soon complete a comprehensive selective catalytic reduction project on all four units at its Big Bend Power Station that will make Big Bend among the cleanest coal plants in the U.S. The project — the centerpiece of the company’s 10-year, $1.2 billion air quality improvement program — is on schedule to meet all of its air quality improvement goals by mid-2010.

  • Big Stone Remodels ESP into Pulse Jet Fabric Filter

    Short of replacement, what are your options when your original electrostatic precipitator fails to meet your current emissions and opacity requirements? The management of Big Stone Plant chose the unconventional, yet economic approach of building a pulse jet fabric filter inside the casing of the old electrostatic precipitator. The upgrades restored plant availability and prepare the plant to meet the next regulated reductions in particulate matter emissions.

  • Peru: The Potential to Become a Regional Energy Hub

    Water and gas provide the energy for Peru’s power generation sector, and the country could generate considerably more, especially from hydro and wind. While the nation strives to extend electricity service to all its citizens, it’s also looking beyond its borders for potential future customers.

  • Real-Time Control of Coal Quality Improves Reliability

    Poor lignite fuel quality had plagued the Red Hills Power Plant since it began operation eight years ago. The solution: real-time measurement of coal properties that has allowed Red Hills Mine to carefully monitor fuel quality and adjust fuel collection processes to ensure that only high-quality fuel is delivered to the plant. Now all delivered fuel is consumed, and plant reliability is much improved. It’s a classic win-win project.

  • Strategies to Reduce Sulfuric Acid Usage in Evaporative Cooling Water Systems

    Concentrated sulfuric acid is often used to prevent calcium-based scale formation on condenser and heat exchanger tube surfaces in power plant evaporative cooling water systems. Unfortunately, the chemical’s price has jumped more than 300% over the past three years. If the rising cost of water treatment has you under the budget gun, here are some alternative strategies that can reduce or even eliminate your sulfuric acid usage.

  • Determining Carbon Capture and Sequestration’s Water Demands

    The U.S. Department of Energy’s National Energy Technology Laboratory is pursuing a new integrated energy-water R&D program that addresses water management issues relative to coal-fired power generation that takes into account the major impacts of CCS on water use. The goal of this research is to promote more efficient use of water in power plant operations and increase the availability of heretofore unusable waters for power plant use. Those practices can mitigate the impacts of CCS on power plant water use and allow for continued development of energy resources.

  • Harnessing Energy from Upward Heat Convection

    The atmospheric vortex engine exploits the natural energy content of the vortex produced during upward heat convection in the atmosphere. The heat source can be solar energy, warm sea water, warm humid air, or even waste heat rejected in a cooling tower. When mature, the technology — currently in the small-scale testing phase — promises to be an efficiency game-changer for fossil-fired power plants.

  • Universal Beam Clamps

    Harrington Hoists launched its new Universal Beam Clamps, a product line that complements its core product offering of hoists, cranes, and material-handling equipment. The beam clamps are available in metric tons rated 1 through 10; they meet ASME BTH-1 and ASME B30.20, and comply with portions of ASME B30.16; and they have a design factor […]

  • Going Coastal: The Case for Offshore Wind

    Offshore wind projects involve regulatory, technological, and economic challenges that are greater than those confronted by onshore wind projects. Overcoming these challenges will be necessary to permit offshore wind to achieve its full potential.
