  • Biomass Power Under Attack

    Biomass energy has been an up-and-down industry for decades. As public awareness grows, it inevitably influences new tax legislation and environmental regulations. Two recent events have made the climate for development of this renewable resource even more volatile.

  • Semi-Automated Tube Bundle Cleaner

    Part of a family of automated and semi-automated tube-cleaning accessories, the new Saflex 2000 makes tube bundle cleaning more productive because it can clean four times as many tubes in a given period as manual water jetting, says NLB Corp. Operating at pressures up to 40,000 psi, the semi-automated accessory cleans two tubes (ranging from […]

  • No-Glass ORP Sensors

    Engineers and technicians searching for a high-performance oxidation-reduction potential (ORP) sensing solution will find that the S10 and S17 ORP Sensors from Electro-Chemical Devices (ECD) feature a no-glass design with platinum or gold sensor tips to operate safely in a wide range of applications. ECD’s ORP S10 and S17 Sensors come with easily replaceable ORP […]

  • Pre-Cleaner for Vulcanized Conveyor Belts

    The new QC#1 MT Pre-Cleaner from Martin Engineering is a high-quality cleaning blade for use on vulcanized conveyor belts. It features a special polyurethane blend and tungsten carbide tip to deliver service life two to three times longer than conventional urethane blades, the company claims. Designed to provide excellent cleaning performance without any break-in period, […]

  • Correction (November 2010)

    Correction In the September issue’s “Taming Condenser Tube Leaks, Part I,” the first full paragraph in the main text on page 57 should say, “If chloride and sulfate in the steam cannot be maintained below 8 ppb….” POWER regrets the error.

  • The Global Smart Grid Scene

    Presenters at the inaugural GridWise Global Forum in Washington, D.C., September 21 to 23 had a lot to say about the prospects for smarter grids. This synopsis of facts and opinions shared at the event, which attracted several smart grid A-listers, looks at the major challenges ahead, especially for the U.S.

  • Matching Load and Generation at UCSD

    “Smart Power Generation at UCSD” explains how the University of California, San Diego (UCSD) is maximizing the value of combined heat and power. However, like any other grid-controlling entity large or small, the campus has to match generation and load. Its two Solar Turbines gas turbines operate in baseload mode 24/7 while the cogeneration side of the plant maximizes the value of “waste” heat and electricity that isn’t needed to serve immediate load by generating steam and chilled water for campus heating and cooling.

  • Combined Heat and Power Across the U.S.

    The University of California, San Diego (see “Smart Power Generation at UCSD”) is just one of many combined heat and power (CHP), or cogeneration, systems in the U.S. A 2008 report by Oak Ridge National Laboratory (ORNL), “Combined Heat and Power: Effective Energy Solutions for a Sustainable Future,” notes that Texas has the most CHP capacity—much of it used by the petrochemical and petroleum refining industries. California ranks second, largely a result of “industrial demands, stringent air quality requirements, and effective policies that encourage adoption of CHP.”

  • Elner Shimfissle and Old Tom: In Praise of Electricity

    Fannie Flagg’s fictional Aunt Elner Shimfissle reminds us of the power and the glory of electricity, a lesson we shall not forget.

  • TREND: Smart Grid Complications

    Despite a trendy moniker and lots of hype and interest, the smart grid has been facing some major setbacks of late, as regulators and customers begin challenging some of the claims for what interconnected smart meters will deliver in the way of tangible benefits.
