  • Turbine Inspection

    Recent advances in natural gas exploration and extraction technology have led to skyrocketing projections of the amount of recoverable natural gas within US borders. This energy boom will result in the expanded use of gas-fired power plants to provide electricity to US homes and businesses over the coming decades. Not only does this mean cleaner and more abundant energy for the US environment and ...

  • In situ weld repair of blade tenon of steam turbine in a power plant

    During one of the routine inspections in a nuclear power plant, it was found that a tenon of one of the third-stage blades of the Low-Pressure (LP) turbine had been worn/broken off the turbine blade, leaving only the remaining tenon riveted to the shroud piece. With only one of the two tenons remaining, the blade was at risk of getting freed from the shroud piece. Hence, it was necessary to ...

  • Reliable silica monitoring supports power station efficiency

    West Burton B CCGT is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million UK homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Sean Todd, the Plant’s Control ...

  • Fukushima Meltdown Hastens Decline of Nuclear Power

    On May 5, 2012, Japan shut down its Tomari 3 nuclear reactor on the northern island of Hokkaido for inspection, marking the first time in over 40 years that the country had not a single nuclear power plant generating electricity. The March 2011 earthquake, tsunami, and subsequent Fukushima Daiichi nuclear meltdown shattered public confidence in atomic energy, thus far making it politically ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Oil and water don`t mix

    Small spots of motor oil on your driveway look tacky enough. Leaks of hydraulic oil from the hydro turbine of a big pumped-storage plant are not only more noticeable, but they also could end up in the facility's sump or in its reservoir, as well. At the Blenheim-Gilboa Pumped Storage Power Project in New York's Catskill Mountains, there's another reason leaks are unacceptable. The New York Power ...
