Building on GE Aviation’s experience, GE Gas Power has advanced emissions performance and operational flexibility of the 7E advanced secondary fuel nozzle. Using 3D printing, its manufacturing process is flexible, fast, and economical.
This new product allows for a solution that provides flexible performance outcomes. So the same hardware solution can give you low turndown today and peak MW as your future needs change.
The 7E advanced secondary fuel nozzle provides a rapid, cost effective energy boost for power generators. The redesigned turbine fuel nozzle lowers NOx, allowing increased emissions-compliant megawatts by increasing the unit firing temperature, with no hardware tuning. That simple shift can yield as much as $250,000 annually, with an improved power rating. These outcomes were tested and proven in the field as of July 2021.
Operators can expect rapid returns with the 7E advanced secondary fuel nozzle—and quick installation as well. Some upgrades require waiting for an outage or scheduling one specifically. This nozzle upgrade is easy to install with no extended outage needed. Installation can be completed in as little as 48 hours.

"GE certainly gave us a jump in availability before summer starts taxing us. Our 107EA turbines aren’t just better, they’re helping us meet emissions best practices, which is the sustainability example Cooperative Energy wants to set as one of the major generation and transmission cooperatives in Mississippi."
Jacob Staples (Site CPM Manager)
Cooperative Energy in Mississippi was close to going over its allowed CO2 output. The source? One 107EA combined cycle gas turbine. While underfiring just to be in compliance, Cooperative Energy sought lower-NOx solutions and added megawattage for summer demands. GE’s advanced secondary fuel nozzle (ASFN ) was installed in less than 48 hours—and with its new configuration that premixes air and fuel in DLN1/1+ systems, Cooperative energy saw lower emissions, more MWs, and renewed reliability.
Slash maintenance costs, manage emissions, and extend availability with proven combustor tuning technology.
Reduce the emissions and high maintenance factor impact tied to primary re-ignition events, by automatically restoring pre-mixed operation without interrupting load.
