  • Maintenance tips for cooling towers - White Paper

    Cooling towers are prone to the typical causes of rotating machine failure such as misalignment, but also face a range of specific environmental challenges, including high or gusting wind speeds, dust, sand and, in coastal locations, high concentrations of salt. In the 1990s, for example, vibration and accelerated wear caused a fan blade to shear off a cooling tower in Pennsylvania, ...

  • How to Increase Your Industrial Cooling Tower Efficiency

    Although cooling towers are generally some of the most cost-effective cooling mechanisms as compared to other cooling technologies (such as many dry air cooling systems), it is still important to monitor your industrial cooling tower efficiency and run it as seamlessly as possible. This will ensure your facility can: Save energy Reduce the amount of ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Athlone Cooling Towers Demolition, Cape Town, South Africa Case Study

    The Athlone Cooling Towers in Cape Town, South Africa, were condemned due to structural damage caused by the heavy Cape winds. A decision was taken to demolish the Cooling Towers, despite the technical challenges and potential risk to nearby populations that this posed. In 2011, Knight Piesold was appointed as project manager to assist with the demolition of the Athlone Cooling Towers, by the ...

  • Wind power status, barriers, and opportunities

    In the wake of the oil crisis in the early 1970s, governments around the world were anxious to diversify energy supply away from fossil sources, and so harnessing the wind was seen as an important component of this policy initiative. A decade of research saw a Danish designemerge as the industry standard: the three-bladed, horizontal axis, upwind machine. A modern wind turbine comprises a tubular ...

  • Giant FRP Cooling Towers Built for Zinc Refinery Modernization

    Fabricated Plastics Limited of Maple, Ont., had previously built zinc sulfate cooling towers of FRP for various zinc refineries in North America when it was awarded a contract to produce six of the giant cooling units for a refinery in Tasmania, Australia. Each 5.9 m (19'4") in diameter and 18.3 m (60 ft.) high the Australian towers are major components of the plant which transforms raw zinc ore ...

  • Stellio heliostat set to cut CSP tower costs by 20%

    A new heliostat modeled on South African data is using a pentagonal reflector design, innovative construction techniques and smart software to boost the cost efficiency of tower plants. Heliostat fields typically contribute about 50% of the capital investment for CSP tower plants, according to a study by SBP Sonne, the German engineering firm which has ...

  • On the application of miniSoDAR technology to wind energy

    Introduction In the late 1990’s wind turbines with nacelle heights exceeding 60 meters were introduced to the wind energy community. Initially, wind prospecting and siting studies continued to use 50-meter wind towers and extrapolate the measurement to the nacelle heights. It was quickly determined that this approach was not sufficient for the placement of these tall turbines. The next ...

  • How much wind is needed to power a home turbine?

    First do you have what it takes? Whether you are considering a small rooftop unit or a large residential turbine you need to know how much wind power is in your area. Wind resource maps, published by the US Department of Energy show airflow speeds at 50 meters (150 feet) above the ground and are a great resource in deciding if you are in a viable location. That's great if you are installing a ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • What’s the Future of R&D in the Wind Industry?

    When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...

  • CU-Boulder leading study of wind turbine wakes

    While wind turbines primarily are a source of renewable energy, they also produce wakes of invisible ripples that can affect the atmosphere and influence wind turbines downstream -- an issue being researched in a newly launched study led by the University of Colorado Boulder's Julie Lundquist, assistant professor in the atmospheric and oceanic sciences department. The study, called the Turbine ...


  • Case study - Wind turbine manufacturer implements clean air initiative

    Overview When you think about generating electricity from wind, clean energy comes to mind. However, the wind turbine production process can be a major source of air pollution without the proper controls in place. Manufacturing and painting the blades, towers and nacelles requires composite construction material and solvent based coatings. The potential to emit Volatile Organic Compounds ...

  • 115. Calgary’s wind powered LRT an incredibly successful system: Nenshi

    The C-train in Calgary is one of the greatest examples of electrified transport in Canada. It is overwhelmingly popular with residents – it boasts an average weekday ridership of 325,000. It has kick started smarter, denser development around its stations. And best of all it and the City of Calgary’s operations are 100 per cent powered by renewable energy. “It's hugely important ...

  • Integrated solar and wind energy powers oil recovery system

    Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) panels to power pneumatic and electric submersible ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Tillsonburg: From tobacco farming to building wind turbine blades

    The story of Tillsonburg is probably close to the ideal example of what the Ontario government was looking for when it enacted the Green Energy Act in 2009. A small town of 16,000 people in southwestern Ontario, Tillsonburg’s history is famously celebrated in Stomping Tom Connor’s distinctive drawl when he sung about making seven ...
