What can upgrading do for you?

The 7E capacity performance package improves performance in DLN1 and DLN1+ combustion systems by combining two robust technologies: axial fuel system and corrected parameter control.

Axial fuel staging (AFS) helps increase the emission-compliant operating range as part the package. AFS hardware pairs with corrected parameter control (CPC) software, which helps enhance existing turbine control and improve control of unit exhaust temperature. GE Gas Power can modify existing combustion systems to provide more power without negatively impacting existing emissions signature.

The technology was initially developed for operational flexibility in 7E turbines. Given its proven capability, use has been expanded into the F/HA fleets as well.

How we get you there

The capacity performance package promotes start up reliability as well as combustion enhancements. Its software helps ensure the turbine is ready to start with pre-start systems checks and monitoring software, for example.

By introducing gas fuel into the head end of the transition piece through a new fuel circuit, AFS helps achieve notable combustion enhancements. In addition, a new wrapper system with Nimonic transition pieces is deployed.

At the same time, CPC helps enhance the existing static turbine control with an all load temperature reference, which is updated as ambient conditions change. This enables better control of unit exhaust temperature and emissions.
