Energy Newsbriefs Blog

The WSU Energy Program Library prepares this current awareness blog with funding from the U.S. Department of Energy State Energy Program. These articles highlight energy-related news, articles, and reports about energy efficiency, energy conservation, and renewable sources of energy for energy professionals and interested members of the public.

Energy Efficiency: A Little Knowledge Goes a Long Way

Automation World, Mar. 2017, by James R. Koelsch.
https://www.automationworld.com/energy-management/energy-efficiency-little-knowledge-goes-long-way

"There has been a lot of talk in industry about energy efficiency in manufacturing facilities, but the realities of high cost and limited returns have stymied action. Some best practices, though, could tip cost calculations in favor of moving forward."

"Computer program summarizes test results from periodic turbine inspections."

Boiler Tune-Up Cuts J.H. Baxter’s Annual Energy Costs By An Estimated $21,100

Energy Trust Blog, Jan. 5, 2017.
https://blog.energytrust.org/boiler-tune-cuts-j-h-baxters-annual-energy-costs-estimated-21100

"A Kewanee steam boiler is the backbone of J.H. Baxter & Co.’s wood-treatment facility in Eugene [Oregon]. But over time, the boiler’s fire tubes built up a layer of soot that decreased efficiency. The solution was a simple boiler tune-up that boosted efficiency by 8.5 percent, saving more than 41,000 therms per year. Not only did the project cut the facility’s annual energy costs by an estimated $21,100—90 percent of the cost of the tune-up was paid for through Energy Trust of Oregon’s 90 by 90 industrial operations and maintenance offer."

Chiller Plant Optimization: Improving On Variable Primary Flow Chilled Water System Operation

"The larger or more complex a cooling plant becomes, the more challenges to its efficiency it will face. When applied wisely, modern controls and equipment can rise to meet those challenges. Read up on active balancing, pump dynamic differential setpoint control, and more responsive tactics for when the worst thing you can do is just go with the flow."

A Road Map for Optimized Maintenance

Flow Control, Nov. 1, 2016, by Michael J. Trainor.

"Unexpected failure of machinery is never a welcomed option for any plant, especially in the case of critical assets. Productivity may take a big hit when an asset goes down for emergency fixes. Could a developing problem have been detected earlier? Could the failure have been prevented or even predicted? An operation’s maintenance strategy — or lack of one — holds the key."

Commitment to Maintenance Leads to Reliability [District Energy]

Liftoff for Drones: New Law Frees Co-ops To Begin Operational Drone Use

Rural Electric Magazine, Sept. 2016, by John Vanvig.
http://remagazine.coop/faa-drone-laws-allow-co-op-use/

"With technological constraints and regulatory uncertainties slowing their takeoff, utility UAS use has languished. But thanks to a recently signed federal law allowing their use by utilities, rapid advances in range and data-handling capabilities, and the public’s becoming more comfortable with UAS presence, experts expect UAS deployments to soar."

Pumping Prescriptions: What Happens to Power & Efficiency When a Pump Wears Out?

Pumps & Systems, Sept. 2016, by Lev Nelik.
http://www.pumpsandsystems.com/pumps/september-2016-what-happens-power-efficiency-when-pump-wears-out

"When a pump experiences internal wear, its performance drops. Flow is reduced and efficiency plummets. But what happens to power? Does it drop, stay the same or increase? The answer to this question depends on how a pump wears internally. In extreme cases, when the impeller is completely worn, there will be no flow and hardly any power. But in many cases, tight clearance parts, such as wear rings and bushings, are the first to wear."

How IIOT Monitoring Improves Pump Maintenance

Flow Control, Jul 2016, by Brett Burger.
http://www.flowcontrolnetwork.com/how-iiot-monitoring-improves-pump-maintenance/

"The Industrial Internet of Things (IIoT) will eventually connect tens of billions of “things” businesses use to operate with other machines, the cloud, control systems and people. Pumps are squarely on the list of “things,” and like many other big-iron assets that do not generate high-tech publicity, they have much to gain with this surge of technology. Why do we need IIoT pumps? What does an IIoT-enabled pump look like?"

Smart Buildings Demand A Smarter Approach To O&M

Engineered Systems, Apr. 2016, by Robert S. Novak.
http://www.esmagazine.com/articles/97666-smart-buildings-demand-a-smarter-appoach-to-om

"In the beginning, the goal is to enable the operations and maintenance staff to work with the system to give it the best chance to perform as designed. Later, the vision is a culture of continuous improvement that can withstand changes in technology and personnel. In between? Plenty of opportunity for thoughtful operations and standardized routines."
