  • Ovation Blog: Heat Recovery Steam Generator Purge Credit Success

    Jim Cahill
    At the 2019 Ovation Users’ Group Conference , a U.S. power producer shared their story about shrinking down to a 17-minute purge on their combustion turbine (CT) startup. A heat recovery steam generator (HRSG) purge removes combustible levels of fuel mixtures prior to startup. A purge credit allows credit for a prior purge for the next startup with a normal shutdown occurs or modified fuel systems for both CT and duct…

  • Safety Instrumented Systems Blog: Reducing Level Detector Proof Testing Complexity

    Jim Cahill
    Each safety instrumented function (SIF) including its sensor, logic solver and final control element must be periodically tested to make sure it will perform as designed in the event of a safety demand. These “proof tests” help to uncover and failure conditions which may have developed since the last proof test or safety demand. A new whitepaper, Reducing the Complexity of Proof-Testing with New Generation Point Level…
