A relatively common major repair encountered by generator owner/operators is replacement of the stator winding. There are two general methods for designing/constructing stator windings, Jamie Clark of AGT Services Inc told attendees at the 501F Users Group’s 2020 Conference and Vendor Fair, last February, at the Hilton, West Palm Beach, Fla. They are: Conventional: It […]

The 7EA Users Group has joined Power Users, the umbrella organization for managing and coordinating the technical programs for many of the electric power industry’s leading user groups—including 7F, Combined Cycle, Steam Turbine, Generator, and Power Plant Controls. Sheila Vashi (sheila.vashi@sv-events.net) of SV Events will coordinate the 2020 conference and vendor fair at the J

Special to CCJ Onsite By Benjamin Emerson, Jared Kee, and Tim Lieuwen, Turbine Logic; Bobby Noble and Leonard Angello, Electric Power Research Institute; Dallas West, ENMAX Energy Editor’s note: This article introduces a novel combustion-dynamics monitoring (CDM) algorithm and a case study to demonstrate its successful detection of a gas-turbine combustor fault which otherwise might

There were two special live technical presentations during Week 3 of the 7F Users Group’s 2020 Digital Conference—one by PSM, the other by Shell/Advanced Chemical Technologies—and one extended live technical presentation from Doosan Turbomachinery Services. The video recordings, available on-demand to owner/operators, bring you up-to-date on the products and services offered by these companies to

The presentation at the 7F Users Group’s 2020 Digital Conference through Week 3 (two weeks to go) that has generated the most questions and discussion among attendees concerned a leak in a plate-and-frame lube-oil cooler. Go figure! How could a mundane leak generate this much interest at a high-tech meeting? Read on: There are some

The 7F Steering Committee invigorated last Wednesday’s (Day 7, July 1) program by leading off with a discussion session on rotors rather than a user presentation on the subject, as had been the norm for the other days of the event.

One of the unique aspects of the 7F Users Group’s 2020 Digital Conference is the opportunity to interact online with the OEM and nearly 50 third-party solutions providers. Ten companies in the latter group were selected by the steering committee to conduct live technical presentations of one or two hours during Weeks Two, Three, and Four of the five-week

Vendor breakout presentations SVI Dynamics/SVI Industrial Defining and Implementing SCR Improvements on Gas Turbine Exhaust Stringent regulations on NOx, CO, and ammonia slip are dictating the need for highly efficient SCR systems. Although CO and SCR catalyst designs are advancing to meet these new regulations, SCR system designs are not always equipped to manage the

Dr Ahmed Shibli, managing director, European Technology Development Ltd (ETD), recently contacted Consulting Editor Steve Stultz to invite CCJ’s participation in the upcoming High-Temperature Defect Assessment (HIDA) conference, April 20-22. The virtual meeting will assess the behavior of high-temperature plant components containing defects and operating under steady and/or cyclic load conditions. This is considered by

Diaphragms are a hot topic at most conferences where owner/operators gather to discuss issues with their steam turbines, such as the Steam Turbine and Combined Cycle User Groups operating under the Power Users Group umbrella. To get the most from these meetings, it’s important to know the basics of steam-turbine design, the differences among machines
