A NACE International paper, HRSG Tube Failures: Prediction, Diagnosis and Corrective Actions highlights the challenge of these failures: Many HRSGs were originally designed for base load operation. Recent economic factors have led to drastically increased cycling of many units. This has exacerbated the rate of failures. These leaks can lead to forced outages that create […]
Author: Douglas Morris There’s a lot of talk in the industry about the Industrial Internet of Things (IIoT), digital transformation, and digital technologies. There is enough interest, though, among utility executives in the promise of digital technologies–which typically includes some combination of wired and wireless sensors for monitoring, sophisticated algorithms, machine learning and artificial intelligence–that […]
Author: Douglas Morris A while back, I wrote about using advanced control techniques to reduce steam temperature swings which can lead to boiler unavailability. Control improvements are one method to address this problem, but so is evaluating the mechanicals in the reheat and superheat sections of a plant. Taking a closer look at outage data […]
Thermal fatigue in heat recovery steam generator (HRSG) tubes can lead to lost electrical production. Emerson’s Douglas Morris, a member of the Power and Mining industry teams, recaps a presentation he attended by Emerson’s Mark Nord. Tube leaks in HRSGs are a problem for all combined cycle plant operators. The Generating Availability Data Systems (GADS) […]
In an earlier post, Plasma Gasification-Municipal Waste as a Power Source, we highlighted this process as an effective way to create energy from waste. I received news from Emerson’s Barbara Hamilton that the Industrial Energy consulting and global project services teams have been working on a project expected to come on line in 2014. The […]
