Avoiding Dangerous Malware Infections
The malware WannaCry/WannaCrypt has been all over the news recently. Since most of the operator and engineering workstations used in distributed control systems (DCSs) and supervisory control and data acquisition systems (SCADA) are PC-based, the question was naturally could these have been/or be impacted by this dangerous malware. I caught up with Emerson’s Jaime Foose . She noted that it is important to point...

Improving Burner Control with Gas Chromatographs
There once was a time for industrial manufacturers when they received fairly homogeneous supplies of natural gas that did not vary much in energy content. Here in the U.S. with the rapid increase in shale gas production as part of the overall energy mix, there is more variance. In a Power magazine article, Gas Chromatographs Offer New Technology for Power Plant Burner Control , Emerson’s Bonnie Crossland describes...

Connect with Emerson Power Industry Experts @PowerGenWeek
Author: Matt Cate POWER-GEN International kicks-off next week (December 13-15) in Orlando, FL. Emerson experts will be available to discuss ways utilities can improve unit availability and achieve more flexible operations. They’ll also share strategies for making shrinking plant workforces more effective. The following are some ways you can connect with them. Attend a Technical Session Emerson experts...

Improving Power Plant Staff Effectiveness
Author: Douglas Morris With the large number of power workers having already retired, there is a definite shortage of expertise within the industry. Not only are workers new, but companies are having difficulty hiring enough skilled employees. Although most new hires are diligent and eager to learn, they lack the experience necessary to make critical decisions. Younger engineers, technicians, and operators may have...

Improving Flexible Power Plant Operations
Author: Douglas Morris Increasingly, plants are having to adapt to more flexible operations as gas prices remain low and renewables are added to the generation mix. Gas units are shut down, started up in the morning, follow load during the day, and then are shut down or idled again. Source: National Renewable Energy Laboratory: The Western Wind and Solar Integration Study Phase 2 Coal plants are also asked to operate...

Increasing Power Plant Reliability via Smart Monitoring and Diagnostic Centers
Author: Douglas Morris Today’s fossil power plants are faced with the challenge of stabilizing the fluctuating grid power supply due to renewable generation and, as a result, plants originally designed for base load are subject to load cycling. A principal consequence that cycling imposes is increased amounts of thermal stress ( creep fatigue ) on boilers and heat recovery steam generators (HRSGs) which contributes...

Renewable Energy and Unintended Consequences
Author: Douglas Morris “Because the wind blows during stormy conditions when the sun does not shine and the sun often shines on calm days with little wind, combining wind and solar can go a long way toward meeting demand, especially when geoth...

Risks and Rewards of Different Technologies in Power
Author: Douglas Morris “The fascination of a growing science lies in the work of the pioneers at the very borderland of the unknown, but to reach this frontier one must pass over well traveled roads; of these one of the safest and surest is the broad highway of thermodynamics.”— Gilbert Lewis (1923) With growing global concerns about reducing carbon emissions, the power industry has received its share...

Things That Might Surprise You about Power
Author: Douglas Morris Most often I write about a current issue concerning the industry or about how an operational problem might be addressed in a plant. I thought I’d take a different tack and highlight some interesting articles where you might learn something interesting or new (or you might just shake your head). On Animals… Imagine a situation where an animal could take down an entire country’s...

Improving Power Plant Operations with Second-Level Automation
When many plants were built years ago, they were instrumented to provide what was required for safely manage the process. As time has passed, the requirements are far greater for efficiency, reliability and regulatory demands. In a Power Engineering International article, Modernizing old plants to meet new demands , Emerson’s Jonas Berge describes how power plants are being modernized with a second layer of automation...
