At the 2019 Ovation Users' Group Conference, a U.S. power producer shared their story about shrinking down to a 17-minute purge on their combustion turbine (CT) startup. A heat recovery steam generator (HRSG) purge removes combustible levels of fuel mixtures prior to...
As electrical power producers and cogeneration facilities must handle the load swings produced on the supply and demand side. Optimizing steam temperature control is one key way to improve the reliability of on boilers and heat recovery steam generators (HRSGs) caused...
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...
Optimizing steam temperature reduces energy costs and increases operational reliability. In an 18-minute webcast, 3 Steps to Better Steam Temperature Control, Emerson's Douglas Morris shares how advanced steam control for boilers and heat recovery steam generators...
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...
The electrical power generation mix continues to shift to increasing natural gas usage due to growing supplies from shale gas production. In a Power article, How to Increase Power Plant Asset Reliability Using Modern Digital Technology, Emerson's Juan Panama describes...
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...
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...
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...
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...
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...
I discovered Nick Denbow's Industrial Automation Insider blog this weekend and added it to my list of automation and process industries-related blogs. He had a post about university students studying the feasibility of using liquefied natural gas (LNG) as a fuel...
