Exploiting the difference in salt concentrations between the freshwater runoff from river mouths at the point where they meet saltwater reservoirs such as seas and oceans to harness power isn’t a new thing.

Siemens Industry Inc. introduced two new SIMATIC Burner Management Systems (BMS) to give end users greater flexibility to cost-effectively comply with revised 2011 burner standards. Designed with TUV-certified hardware and customizable software, the compact BMS300F and BMS151F systems comply with NFPA, IEC, and ANSI/ISA standards for single- or dual-fuel applications with single or multiple burners. […]

It promises to be the most widely and easily distributed power generation technology to date: heat, captured in fabric. Work at Wake Forest University in North Carolina has led to the creation of a thermoelectric fabric called Power Felt that can turn theoretically any form of heat (body heat, waste heat from a car, or heat from any other source to which the material can be attached) into sufficient electrical current to help power devices or the systems the material is in contact with.

Spade drill bits are routinely used by electricians who do wiring and cabling, especially for drilling holes in wood for conduit runs. But traditional spade bits sometimes vibrate badly and dull after just a few uses. The new IDEAL Power-Spade spade bit helps eliminate these problems to provide an increased level of performance, whether the […]

Three South Korean Firms Opt for MHI’s J-Series Turbines. Japanese firms Marubeni Corp. and Mitsubishi Heavy Industries (MHI) on March 22 said they had been jointly awarded orders for three large-scale combined cycle electric power projects in Korea totaling 3,800 MW. The plants are the 950-MW 2nd Pyeongtaek Combined Cycle Power Plant, the 1,900-MW Dongducheon […]

Patterns of coal trade have been shifting in recent years as demand surges in Asian countries. Whereas Japan and the European Union (EU) have long been the world’s largest hard coal importers, China and India are now emerging as top importers. This surge has shifted the center of gravity in international coal trade to the […]

In 2009, the North Carolina Asheville Regional Airport Authority (Airport), with partners Progress Energy Carolinas Inc. and Charah Inc., began development of the Westside Development Fill Project (Westside Project), a long-term infrastructure strategy located in the southwest quadrant of the Airport’s property. The project included phased construction of a developable pad for general aviation and commercial use, a new taxiway running parallel to the existing runway, and a major expansion of the existing runway.

Following safety rules is the foundation to eliminating injuries. Commonly, a safety presenter will say that safety rules are “written in blood.” At one time, such dramatic statements were a way to get attention and illustrated the seriousness of following safety rules. Today, more highly educated workers demand less drama and more facts.

This is the fifth in a series of predictive maintenance (PdM) articles that began in the April 2011 “Focus on O&M” in which the essentials of PdM were introduced. In the May and June 2011 issues, we explored specific PdM techniques, such as motor-current signature analysis and oil analysis. In the November 2011 issue, we introduced the value of thermographic analysis and its routine use. This installment focuses on ultrasonic and vibration analysis.

In February 2012, the Nuclear Regulatory Commission approved two combined construction and operating licenses for Southern Nuclear’s Plant Vogtle Units 3 and 4 in Georgia. They were the first licenses ever approved for a U.S. nuclear plant using the one-step licensing process and the first allowing construction in more than three decades. Now the real work begins.
