Acknowledging that ANSI centrifugal pumps often need to be installed in areas where space is at a premium, Griswold Pump Co. has developed the 811CC (Close Coupled) ANSI centrifugal pump. This pump offers the features and flexibility of standard Griswold 811 ANSI pumps but with a smaller electrical motor encased in a compact package. Despite […]

In order to operate aging nuclear power plant instrumentation and control systems for up to 60 more years or longer, there must be a smooth transition from existing analog technologies to advanced digital platforms. For this to occur, electromagnetic compatibility concerns related to both qualification testing and the electromagnetic environment must be addressed to ensure safe and reliable operation of these systems within the plant’s electromagnetic and radio frequency interference environment. By understanding the regulatory requirements and sharing implementation experience, digital system upgrades can be installed successfully.

CHLOR*RID International launched the Chlor*Ion Meter, a handheld digital testing device that electronically measures chloride on surfaces with an internal ion-specific electrode. Most surface chloride testing devices offer an external electrode on a cord, but these could be damaged in the field, CHLOR*RID says. Because it digitally measures chloride on surfaces, the Chlor*Ion Meter’s ion […]

Digital fieldbus technologies, including Foundation fieldbus and Profibus, are increasingly being used with success in the nuclear and fossil fuel power industries. This article compares a conventional control system with a Foundation fieldbus – based digital control system used in a typical circulating water system in a nuclear power plant. As shown in this example, using digital fieldbus technologies can result in significant savings in terms of installation and hardware costs.

Bernard’s new customizable W-series water-cooled MIG guns and water-cooled Centerfire consumables are designed to meet the wide-ranging needs of high-amperage, water-cooled metal inert gas (MIG) applications. The W-Guns (shown here) are durable and may be customized. Users can choose neck styles, cable lengths, handle styles, consumables, and direct plugs. The W-Guns are rated to 600 […]

In a typical steam power plant, the boiler feedwater (BFW) pump takes suction from the deaerator (DA) and discharges high-pressure water to the boiler through the feedwater heaters. During normal operation, the DA is supplied with steam turbine extraction steam to mix with and heat the feedwater.

Building and engineering software designer Autodesk Inc. announced the availability of AutoCAD Plant 3D 2010, a product that it says brings the benefits of model-based design to mainstream plant design projects. The vast majority of plant design and engineering projects support the operation, maintenance, and expansion of existing facilities. These projects are typically executed by […]

Congress and various states are considering a fundamental restructuring and regulation of our energy policy. Any such effort should be based on facts, but legislators, unfortunately, incline to myths, such as the notion that most of our energy comes from oil.

LUDECA’s new CENTRALIGN ULTRA was specifically developed for the alignment of steam and gas turbines. The system precisely aligns internal elements with upper halves for distances up to 133 feet. Accurate bore measurements can be acquired and wirelessly transmitted without interrupting other processes, saving time over traditional methods like piano wires, micrometers, and optical instruments. […]

Given delays and cancellations of new generating capacity, pushing the existing power generation fleet is more important than ever. At ELECTRIC POWER 2009, multiple presentations explored the premise that an active knowledge management strategy — requiring a blend of digital and human elements unique to each power plant — will help you extract the most productivity from your assets.
