HRSG reliability and performance takes center stage at EHF2025

HRSGs / By

The eleventh annual European HRSG Forum (EHF2025), held May 13–15 in Prato, Italy, drew 95 participants from 20 countries. Co-chaired by Barry Dooley of Structural Integrity and Bob Anderson of Competitive Power Resources, EHF2025 continued its mission of advancing best practices and global knowledge-sharing in combined-cycle and HRSG operations. The event, organized by Mecca Concepts […]

Target repeat chemistry mistakes to stop HRSG and steam-turbine damage (Video)

CCUG, HRSGs, STUG / By

The International Association for the Properties of Water and Steam (IAPWS) opened its Power Cycle Chemistry (PCC) webinar series, with Dr. Barry Dooley presenting and David Addison moderating, outlining how repeat cycle chemistry situations (RCCS) drive the majority of chemistry-influenced failures in fossil and combined-cycle/HRSG fleets. The message was direct: failures are patterned, measurable, and

Handling RCAs with future disputes in mind: More is better! 

7F Users Group, Advanced GTs, CCUG / By

The need to recover quickly from plant equipment failure is often at odds with the patient, methodical steps required to conduct a root cause analysis (RCA) that will be accepted by all parties to a potential dispute among stakeholders down the road. Stakeholders may include plant staff, owner/operator, original equipment manufacturers (OEMs), insurance companies, component suppliers, third-party operation and maintenance (O&M) service providers,

Offline diagnostics keep big generators honest 

Generator Users Group / By

At the 2025 CIGRE International Symposium in Montréal, Kinectrics engineers Sunny Gaidhu, Krzysztof Pyc, and Ashfak Shaikh presented a practical message for powerplant owner/operators based on the paper, “Comprehensive Off-line Diagnostic Testing and Visual Inspections for High-Voltage Turbo Generators.”   Offline diagnostic testing and visual inspections remain a high-value tool for large turbo generators in combined-cycle service. The paper

Practical fixes to steady HRSG performance 

HRSGs / By

Calls to the CCJ editorial office from Tucker York, SVI Bremco’s acoustical engineering guru, are always welcome. This outage season success story comes from a combined-cycle plant with chronic maintenance issues with the “egg-crate” turning vane weldment located in the HRSG transition duct immediately downstream of its 120-MW gas turbine. Over time, vane and support modifications intended to tame aerodynamic loading led to recurring weld

CCGT seminar offers practical HRSG training, case studies, tools 

HRSGs / By

Held in Asheville, NC, in January 2025, the Vogt Power Combined Cycle Seminar delivered concentrated HRSG fundamentals, inspection how-tos, and deep technical case studies. End users compared notes with peers, and Babcock Power’s business units were on hand with design, construction, field, and product expertise. The content below highlights what attendees learned and why you should consider attending in February.  Session

In-service tank inspections slash risk, cost, and downtime at GT sites 

CCUG / By

End users have long treated API 653 tank inspections as necessary pain from challenges associated with fuel handling, confined-space entry, outage coordination, and weeks of operational uncertainty. A recent Electric Power Research Institute (EPRI) Incubatenergy Labs demonstration with Tennessee Valley Authority (TVA) shows there’s a safer, faster path: submersible, autonomous robots that perform phased-array UT while tanks stay online.    The system, developed by Square
