Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

Increasing Efficiency with Advanced Controls [in Heat Treating]

Industrial Heating, Jun. 2014. (Free registration required to view full-text.)
http://www.industrialheating.com/articles/91705-increasing-efficiency-with-advanced-controls?v=preview

"The ever-increasing need to produce higher-quality parts with lower costs requires newer tools to reduce waste and optimize processes. By using advanced gas-handling systems, heat treaters can reduce waste and get a handle on each furnaces gas consumption. Using process modeling for carburizing, nitriding, and carbonitriding can help users develop more efficient processes."

Building Farm And Food Scrap Digesters (Part I)

BioCycle, June 2014, by Nora Goldstein.

"A steady stream of anaerobic digestion facilities are coming on line, most equipped to process food waste. This first of a two-part series profiles several farm digesters. Part I"

More than Heat and Power: Cogeneration with New Gas Engine Technology

Cogeneration & On-Site Power Production, May/June 2014, by Michael Devine.
http://www.cospp.com/articles/print/volume-15/issue-3/features/more-than-heat-and-power.html

"Cogeneration today goes well beyond simultaneously generating electricity and hot water or steam. Today's usable engine outputs can also include heated air, chilled water produced by absorption chillers, and carbon dioxide from purified exhaust. In other words, a single engine-generator can produce two, three or four useful outputs at once. With today's generating technologies, electrical efficiencies up to 45% and total resource efficiencies upwards of 90% are achievable. And cogeneration systems do not necessarily need to operate full-time at full load to be cost-effective–low-cost and low-intensity configurations can bring attractive returns in many settings."

ASME EA-4-2010 - Energy Assessment for Compressed Air Systems. What’s it all about?

Compressed Air Best Practices, June 2014, by Joe Ghislain.
http://www.airbestpractices.com/standards/food-grade-air/asme-ea-4-2010-energy-assessment-compressed-air-systems-what-s-it-all-about

"The ASME EA-4 standard takes the same system approach that is taught in the Compressed Air Challenge® Fundamentals and Advanced Compressed Air System Management courses and provides a prescriptive but scalable process that can be tailored to each facility. Along with system definition, it sets requirements for organizing and conducting the assessment, analyzing the data, and reporting and documenting of the findings."

Preventive Maintenance for Profit

Plant Services, May 2014, by John Kravontka.
http://www.plantservices.com/articles/2014/preventive-maintenance-for-profit/?show=all

"The challenge facing manufacturers is how to implement a maintenance program that will provide immediate return. It can take as many as five or 10 years to train maintenance staff and introduce programs for them to carry out."

Determine Total Cost of Ownership When Selecting Medium-Voltage Drives (Part 2)

Pumps & Systems, Jun. 2014, by Mark W. Harshman.
http://www.pump-zone.com/motors/june-2014-determine-total-cost-ownership-when-selecting-medium-voltage-drives

"Part One of this two-part series (Pumps & Systems, May 2014) explained how factors other than initial purchase price work together to generate the total cost of ownership (TCO) for medium-voltage variable frequency drives (VFDs). Part Two discusses what creates high reliability in a medium-voltage VFD."

The Next Generation of U.S. Energy Efficiency Motor Regulations

Pumps & Systems, Jun. 2014, by John Malinowski.
http://www.pump-zone.com/motors/june-2014-next-generation-us-energy-efficiency-motor-regulations

"Several years ago, the U.S. Department of Energy (DOE) conducted a technical study about how to raise “small” motors’ efficiency levels. After years of study, the Small Motor Rule was passed, covering General Purpose two-digit NEMA frame (and IEC equivalents), single- and three-phase, 1/4- through 3-horsepower motors in open enclosures. Totally enclosed, fan-cooled (TEFC) motors are not included. This regulation will take effect on April 9, 2015."

Grounding Rings Rescue Paper Mill’s Bearings

Maintenance Technology, May 2014.
http://www.maintenancetechnology.com/2014/05/grounding-rings-rescue-paper-mills-bearings/

"At a paper mill in the Midwest, every new motor that is to be controlled by a variable frequency drive (VFD) must be tested. If shaft voltages are found, the motor must be equipped with an AEGIS® Bearing Protection Ring to divert damaging currents to ground. The plant’s electrical reliability engineer established this money-saving specification after many years of frustration from recurring bearing failures."

Eccentric Disc Pumps Create Product Recovery Cost Savings

Pumps & Systems, Jun. 2014, by Wallace Wittkoff.
http://www.pump-zone.com/pumps/june-2014-eccentric-disc-pumps-create-product-recovery-cost-savings

"Targeted product recovery in hygienic manufacturing reduces waste, decreases operating costs and maximizes the use of raw materials and end products."

Industrial Drive Provides Savings for Swedish Paper Mill

Pumps & Systems, Jun. 2014, by Ken Graber.
