HRSGs

HP superheater and reheater drain-system designs and operating practices that do not remove all condensate prior to initiation of steam flow during cold, warm, and hot startups are unable to protect tube-to-header connections, header bores, and nozzle-to-header connections from severe thermal fatigue damage. Such damage has resulted in many premature tube failures and can be

Innovations, looks forward, and disclosure of new ideas were hallmarks of the second annual HRSG Forum with Bob Anderson, held earlier this year in Houston. TesTex Inc, Pittsburgh, Pa, was there with a collection of ideas including its proprietary remote field electromagnetic technique (RFET) equipment (Fig 1). For internal tube inspection, TesTex has developed and operates this

The fifth annual meeting of the European HRSG Forum (EHF2018), held May 15-18, in Bilbao, Spain, attracted 72 participants from 16 countries. Dr Barry Dooley of Structural Integrity Associates Inc, who chaired the meeting as he had done previously, considered the event “highly successful.” EHF is supported by the International Assn for the Properties of

There’s a new test standard for evaluating the efficiency of HVAC and industrial air filters—Classes G1 to F9. ISO 16890, which completed an 18-month phase-in period in June 2018, is the first uniform filter standard for the world, Jason Tiffany, a product development engineer in the Gas Turbine Systems unit of Donaldson Company Inc, told

Managing a powerplant for top performance can be a thankless task. You always seem to be at odds with those controlling the purse strings who don’t fully understand how generating assets work. So you write a business case to illustrate that a better balance sheet would be possible were a given upgrade funded. Sometimes difficult

The Australasian HRSG Users Group (AHUG) celebrates 11 years of service to the industry at the organization’s 2018 meeting at the Brisbane Conference and Exhibition Center, November 11-13. Review the agenda here. Of all the HRSG groups outside the US, AHUG has the second longest history, behind only IMechE in the UK. The shared purpose

The nine Best Practices summarized here conclude CCJ ONsite’s coverage of more than 60 entries in CCJ’s awards program that were recognized by the judges in 2018 for their value to owner/operators of plants powered by gas turbines. Judging of the 2019 entries begins in March. Starting-motor trolley rail increases outage efficiency, safety Florida’s Mulberry
