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 We all know that today’s plants must cycle more; that’s just the expected mode of operation. Keeping plants online with the ability to cycle, particularly cost-competitive combined cycle units, is a focus for most utilities and avoiding heat recovery steam generator (HRSG) tube failures is a good place to start. These failures […]

Italian recycled paperboard producer, Reno De Medici (RDM) Blendecques mill in Saint Omer, France had a big challenge to modernize a control system with a short time window during a planned shutdown. The control system managed two Heat Recovery Steam Generators (HRSGs) that produce steam for the process from two gas turbines and additional burners. […]

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 […]
