Additional Upgrade Technologies
AutoTune
Automated Combustion Tuning Hanwha Power’s AutoTune system provides real-time, automated combustion tuning for the 9E platform. The system continuously adjusts combustion parameters to maintain emissions compliance and combustion dynamics stability across varying ambient conditions, fuel composition changes, and normal engine deterioration. AutoTune eliminates the need for manual combustion tuning during seasonal transitions and reduces the risk of dynamics events that can damage hardware.

9E Gas Turbine FAQs
The LEC III is Hanwha Power’s ultra-low-emission combustion system designed as a drop-in replacement for legacy GE combustion hardware on the 9E (9171E) platform. LEC III delivers sub-5 ppm NOx on natural gas, maintains low emissions across a wider load range than the OEM combustion system, and is compatible with GE models 6581B, 7121EA, and 9171E. Over 70 LEC III and LEC NextGen systems have been installed globally.
LEC III™ is Hanwha Power’s established ultra-low-emission combustion system delivering sub-5 ppm NOx. LEC NextGen is the next-generation evolution, designed for sub-9 ppm NOx with enhanced turndown capability and broader operational flexibility. Both are drop-in compatible with GE 9E legacy combustion models. The choice between them depends on the specific emissions permit requirements, operational profile, and turndown needs of each installation.
Hanwha Power manufactures and supplies 9E hot gas path components including stage 1-3 nozzles and buckets, coatings, and diaphragms. Hanwha Power also provides rotor services, field services, and complete outage support for the 9E platform from its facility in Rheden, the Netherlands. Hanwha Power provides complete 9E aftermarket coverage.
No. The 9E and 7EA are both E-class gas turbines, but they serve different grid frequencies. The 9E operates at 50Hz (3,000 RPM) and is deployed across Europe, the Middle East, Asia, and Africa. The 7EA operates at 60Hz (3,600 RPM) and is used primarily in North America. They share similar technology architecture but differ in component sizing, aerodynamic design, and output ratings.
The standard OEM hot gas path maintenance interval for the GE 9E is approximately 24,000 fired factored hours (FFH) or 900 factored starts (FS). Hanwha Power offers engineered component upgrades with improved alloys, coatings, and cooling designs that can extend these intervals on a unit-by-unit basis, reducing total lifecycle maintenance costs.
