Ask Scott Schreeg of SVI Bremco what turns a manageable exhaust-liner repair into a forced outage and the answer gets specific fast: a failed stud weld, a loosened sheet, or a hotspot hidden behind the liner system. None looks catastrophic at first glance. But once exhaust flow starts working behind the liner, the problem can

As the power industry evolves to meet growing demands for reliability, flexibility, and decarbonization, the success of any power plant depends on one constant: the expertise of the people who operate and maintain it. While advanced technology drives the energy transition, it is a skilled workforce that keeps critical assets running safely and efficiently. At

Legacy Turbine Forum, No. 8 in a series By Luke Williams, PE, Consultant www.geLegacyGasTurbineSupport.com Theme and scope More gas-turbine users may soon face the problem that landed on one Northeast plant’s desk: available fuel-gas pressure was going down, but the operating obligation was not. The supplier said line pressure would be reduced from 320 psig
When fuel-gas pressure falls, check transfer logic before buying compression Read More »
A turbine end user could once treat lube-oil management as background maintenance. That is no longer a safe assumption. During a recent CCJ webinar offered by C.C. Jensen on proactive turbine-oil maintenance and varnish control, presenter Eddie Rowland, joined by former GE Vernova engineer Tom Freeman and Duke Energy lead engineering technologist Steve Malec, made
Proactive turbine-oil maintenance moves to the front line of reliability Read More »
This joint educational webinar equips gas turbine operators and maintenance leaders with guidance and best practices for proactive turbine oil maintenance and varnish control, enabling high turbine availability, long‑term reliability, stable performance, and lower O&M cost. Eddie Rowland, CC Jensen’s clean‑oil expert, will outline modern oil‑management strategies, while Steve Malec, reliability expert at Duke Energy,

The 2026 Legacy Turbine Users Group Annual Conference will be held June 22–25 at the Omni Oklahoma City Hotel, with the 7EA Users Group, Frame 6B Users Group, and Frame 5 Users Group sharing one conference platform. The agenda continues its focus on how to keep mature gas-turbine fleets reliable, where outage dollars should be

Users compare notes The 2025 Legacy Turbine Users Group, consisting of tracks for the GEV 7E, 6B, and 5 fleets, in Minneapolis again demonstrated why user-group meetings still matter for mature fleets. LTUG is not where owner/operators go to hear that legacy machines are old. Everyone in the room already knows that. They go to

For many gas-turbine users, CO-catalyst trouble shows up first as a compliance headache: stack CO starts climbing at low load, differential pressure changes, and the plant is forced to decide whether it is looking at a cleaning issue, a system issue, or end-of-life catalyst. That decision now carries more economic weight than it did a
Legacy Turbine Forum, No. 7 in a series By Luke Williams, PE, Consultant www.geLegacyGasTurbineSupport.com IN THE BEGINNING Engineers who joined the GE gas turbine department in the early days often came from steam turbine design, where cooldown procedures were essential to prevent rotor thermal bow, a condition that can lead to vibration on startup. Several
