Sensing and monitoring systems supplier Meggitt PLC launched the Endevco model 6634C, a microprocessor-based vibration amplifier that has been designed to condition and display rotating machinery data in simultaneous outputs, such as broadband, acceleration, velocity, and displacement. Model 6634C is designed to accept inputs from a single-ended, differential piezoelectric or ISOTRON (IEPE-type) accelerometer, velocity coil, […]

ESAB Welding & Cutting Products’ LAF series of three-phase, fan-cooled DC welding power sources are designed for high-productivity mechanized submerged arc welding or high-productivity GMAW welding. Made for use in combination with ESAB’s A2-A6 equipment range and the A2-A6 Process Controllers (PEK or PEI), LAF welding power sources offer excellent welding characteristics throughout the entire […]

Honeywell has added universal input/output (I/O) transmitters to its family of XYR 6000 wireless products. The transmitters allow manufacturers to wirelessly monitor more plant points with fewer devices. The company says that by transmitting signals from up to three different types of inputs — including measurement devices with a high-level analog, temperature or milli-volt, or […]

UK-based Sherborne Sensors has introduced the LSI series of closed-loop gravity-referenced servo inclinometers to the North American market. The family of inclinometers is specially designed to withstand severe shock and vibration inputs for precise measurements in demanding environments. The series incorporates a unique, flexure-supported torque-balancing system that is rugged enough to withstand shock inputs of […]

High-speed imaging systems manufacturer Photron introduced hardware to extend the normal operating temperature range of the Fastcam SA5 and Fastcam SA2 high-speed cameras. The Range Version (RV) is a new sealed case design that makes the camera models impervious to dirt, dust, and sand. Photron’s RV option includes two serviceable external fans that direct cooling […]

A good default proposition regarding the government’s role in the economy would state that the government should not loan money to an enterprise if the enterprise in question cannot find one single market actor anywhere in the universe to loan said enterprise a single red cent. It might suggest—I don’t know—that the investment is rather … dubious.

In December 2009, representatives of nearly 200 governments met in Copenhagen, Denmark, to hammer out the details of a new climate change treaty. Treaty drafts indicated that industrialized countries would be required to reduce their greenhouse gas emissions—primarily carbon dioxide (CO2)—up to 80% by 2050. Developing countries would not be required to reduce emissions much, […]

One of the primary challenges of reliably burning coal is managing the corrosion experienced by the furnace heat transfer surfaces. Fireside corrosion remains a leading cause of failure in superheater and reheater tubes. Three case studies examine the different failure modes experienced by tubes located throughout the furnace.

Every power engineer must have a firm grasp of the rudiments of how fuel is processed to produce electricity in a power generation facility. With this article, we begin a series of Power 101 tutorials that present these fundamentals in a clear and concise way. First up are the essentials of recovering heat from flue gas.

While the Environmental Protection Agency appears to have initially proposed to regulate power plant coal ash as hazardous waste, there are indications the Obama administration is preparing new federal rules that will at a minimum require utilities to convert coal ash impoundments from wet to dry storage to prevent leaks—a change that would cost tens of millions of dollars but also potentially increase regulated utilities’ rate base and earnings, a Wall Street firm says.
