After discussions with EthosEnergy’s engineering team, the plant contracted EthosEnergy to install ECOMAX® with Tru-Curve auto-tuning on one of the units. This allowed greater flexibility and control from within the control room via a computer-based turbine controller utility. As a result, there was no longer a need for a tuner to come to site after a combustion inspection, hot gas path inspection, or major inspection, saving on planning and costs. It also allowed winter and summer max firing temperature adjustment while mitigating combustor dynamics, increased parts life, and automatic de-rating of the gas turbine if combustion dynamics could not be maintained below established limits.
Because the unit was always tuned, this allowed operation up to the firing limit year-round, truly maximizing the performance of the unit.
After a full cycle of reliable run-time and a review of combustion hardware, the same system was successfully installed on the remaining three gas turbines at the site and later across eight other units for the parent company across North America, including the following engine types: 7FA, 7EA, and 501D.
