CCJ ONsite: 7F Users Group 2012

Update #2

   

User presentations drive energetic discussion

 

The closed sessions at most user-group meetings serving owner/operators of frame-specific gas-turbine assets were structured similarly until recently. The standard formula was to start at the inlet air house and work back through the engine covering, in turn, the compressor, combustion section, turbine, generator, and control system. Session moderators would stimulate discussion using key words, recent experiences announced on bulletin boards, etc. more

More from the "HRSG Spotlight" session

 

Fatigue cracking in superheaters and reheaters was the subject of CCJ ONsite's first report from the half-day "HRSG Spotlight" session at last week's 7F Users Group meeting in San Antonio. Two articles in this report cover presentations on mitigating fatigue cracking in panelized economizers, by Amy Sieben, PE, and in return-bend economizers and drum nozzles, by Scott Wambeke, PE.

Wednesday Vendor Presentation Recap

 

Three breakout sessions were conducted in each of two time slots Wednesday afternoon just ahead of the vendor fair. Six companies presented: DNV KEMA, Environment One Corp, Praxair Surface Technologies Inc, Pratt & Whitney Power Systems, Turbine Technology Services Inc, and TOPS. Expectation is that the presentations will be posted to the user group's new website at www.7fusers.org in the coming weeks so attendees can access information missed. Precises of presentations attended by the editors are below.
