  • 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 ...

  • VSEP improves industrial boiler performance and reduces blowdown frequency by a factor of ten

    In the steam boiler industry, high purity feed water is required to ensure proper operation of steam generation systems. High purity feed water reduces the use of boiler chemicals due to less frequent blowdown requirements (reducing blowdown frequency by as much as a factor of 10). Lower blowdown frequency also results in lower fuel costs. Scale buildup is reduced due to a smaller concentration ...

  • EDI for Power Plants -- Importance of silica

    Power plants use high purity water to drive steam turbines. Cogeneration plants are highly efficient, using both exhaust turbines and high pressure steam turbines. In the 1960's, boilers operated at 450C (840F) and 4MPa (40 atmospheres). Today's leading edge boilers operate at 620C (1150F) and 30MPa (300 ...

  • A Review of Cavitation-Erosion Resistant Weld Surfacing Alloys for Hydroturbines

    AbstractAn improved weld surfacing alloy has been developed and tested to resist cavitation-erosion in hydroturbines. Typical wear characteristics experienced in laboratory testing has been correlated to actual service conditions. A metallurgical evaluation shows that a high strain, work hardening austenitic stainless steel produces superior resistance to cavitational erosion. Several industrial ...

  • 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 ...

  • Unbeatable Proximity

    When it comes to refurbishing a rotor in a power plant, delivery time and shipping costs play a major role. Because of its nearby service center, Sulzer was able to make an unbeatable offer to an Indonesian customer and even bring a retired rotor back into operation. Indonesia contains large oil reserves, e.g., at the Duri Field in Sumatra. There, a cogeneration power plant ...

  • Common Boiler Feed Water Treatment Issues and How to Avoid Them

    When treating boiler feed water (the combination of boiler makeup and condensate return water), several issues can arise that cause boiler scaling, corrosion, fouling, and system failure. Below, we break down the most common boiler feed water issues and how to avoid them to help ensure system efficiency and operational safety. While treating boiler feed water is extremely ...

  • Create new jobs & cut emissions by investing in renewable energy efficiency

    At a time when major US companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both ...

    MIM Holdings Limited has implemented a program of innovations which has enabled the company to open a new mine and add new electricity-using activities while cutting total annual electricity use and carbon dioxide emissions. MIM has committed to the Australian GovernmentĂ­s Greenhouse Challenge. This Federal and State Government sponsored initiative requires companies to reduce emissions of carbon ...


  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...
