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 […]
