Name a power plant that doesn`t rely on valves to control its many systems. Impossible, right? Valves are such an integral and reliably simple component that its relative importance to other components is often forgotten. Nevertheless, valve manufactures continue to perfect valve designs to perform a variety of tasks and to function reliably for longer and longer time periods no matter what the duty. This month`s "Tech Roundup" focuses on some of the new valve technology available from the indus
Water is literally the lifeblood of most power plants. To serve a plant`s needs, water has to be prepared, or treated, to ensure that it is pure and free of elements that may harm or degrade plant systems. This month`s special feature contains three good examples of how plant engineers are managing and treating the water resources at their facilities.
Several organizations are cooperating in the 1995 International Clean Water Conference sponsored by the Electric Power Research Institute (EPRI). It will be held November 28-30, 1995. They include the Pittsburgh Energy Technology Center, PowerGen of the United Kingdom, IEA-Coal Research, the California State Water Resources Control Board and the Empire State Electric Energy Research Corp. Winston Chow and Robert Brocksen of EPRI will cochair the program at the Sheraton Grande Torrey Pines Hotel
Seventy-page handbook provides detailed information on how to reduce the operating costs and increase th efficiency of steam and water systems. The Temperature Control Valve and Steam Trap Applications Handbook covers a range of process steam and water system problems. It provides detailed discussions of the relative merits of the options available to engineers and presents economical solutions to the most common steam and water control problems through the application of temperature-actuated va
The BRG-2000 bearing monitoring kit locates potential bearing failure before the problem can be detected by traditional heat and vibration methods. A useful compliment to all preventative and predictive maintenance programs, the kit is built around the Ultraprobe 2000, a multifaceted ultrasonic tool with a frequency tuning dial that makes it easy for inspectors to tune into a bearing and isolate it for analysis regardless of competing signals. The BRG-2000 kit includes a stethoscope module and s
The Mud Creek Irrigation District (MCID) worked for several years on a proposal to use Lake Huron-Saginaw Bay water for agricultural irrigation. As the project neared the construction phase, a zebra mussel infestation was discovered in Saginaw Bay, halting progress until a 100-percent exclusion of all zebra mussel life forms could be guaranteed.

A handheld instrument, the 100-Mh¥ScopeMeter® Series II, Model 105, puts the high bandwidth of a benchtop digital storage oscilloscope and a true-rms digital multimeter into the hands of any user who needs a portable, battery-powered tool at the job site. The Fluke 105 is the first portable tool to allow easy troubleshooting of the high-frequency signals found in high-frequency applications and is easy to operate with its menu-driven operation and one-button access to more than 30 common
System dispatch from today`s power plants must consider availability of purchase power (buy or sell), fuel prices, and unit availability and efficiency. To gain the best combination of these factors, steam units must be capable of quick removal and return to service.
CompuScope 2125 is an IBM PC AT-compatible ISA bus card which can store up to 1 million samples in on-board memory. It can be used for disk-drive testing, cellular communications, RF receivers, radar, lidar, imaging, non-destructive testing, ultrasonic testing, laser doppler anemometry, high-end video, CCD testing, vibration analysis, laser diode characterization and impact testing. The CompuScope 2125 comes with Gage Scope, a software which enables users to operate the card like an oscilloscope
