  • Thermal mass flowmeters fill the bill in precision gas-ratio control application

    Fiberglass insulation manufacturing is almost akin to making cotton candy. A mixture of silica and other components are melted and passed through a spinning extruder, then rapidly cooled with compressed air (see Figure). As older fiberglass manufacturing plants have demonstrated, manual control of air and natural gas flow to the burners used to melt the initial mix often results in unacceptable ...

  • Vattenfall`s Cogeneration Power Plant Reuter West - Case Study

    The cogeneration power plant “Reuter West” was erected as a base load power plant in the vicinity of the existing “Reuter” plant. The two hard coal fired 300 MW units D and E were commissioned in 1987 and 1989. Today the cogeneration units supplying electricity and thermal energy are operated by Vattenfall Europe GmbH. The heart of each power plant is the boiler where the ...

  • Thermal protection - WWTF gets ahead of the curve with thermal mass flowmeters

    For the Santa Cruz Wastewater Treatment Facility (WWTF), dependability matters. Since 1989, this state-of-the-art WWTF, nestled in a shallow canyon in the coastal city of Santa Cruz, Calif., has been leading the way for renewable energy programs and environmental protection in the West. Santa Cruz WWTF generates its own electric power by using internal combustion engines that burn a mixture of ...
