GE Frame 6B Gas Turbine Combustion Retrofits and Upgrade Solutions

Advance operation performance in single and combined-cycle gas turbines

The GE Frame 6B is one of the most widely installed gas turbines in the global fleet, operating in simple-cycle and combined-cycle power plants across the Americas, Europe, the Middle East, Africa, and Asia. Hanwha Power provides a complete aftermarket solution for the 6B platform: LEC III ultra-low-emission combustion system from our Jupiter, FLorida facility, combined with hot gas path components, compressor hardware, rotor services, and field installation support from our Netherland facility.

This combined offering gives 6B operators a single point of access to combustion retrofits, replacement components, performance upgrades, and long-term service agreements, all independent of the OEM. Whether you are planning an emissions compliance upgrade, a hot gas path component replacement, or a full performance optimization, Hanwha Power can support your next outage.

Benefits of Upgrading 6B-Class Gas Turbines:

• Increased Efficiency: Lower fuel usage and reduced operating costs through optimized thermal performance.
• Enhanced Performance: Upgrades boost output, improve load response, and increase unit reliability.
• Reduced Emissions: Advanced combustion and component design help meet NOx, CO, and particulate matter targets.
• Improved Flexibility: Smoother ramping and better turndown capability make it easier to integrate with renewables.
• Enhanced Safety: Better monitoring, improved fuel isolation, and system protections reduce operational risk.

LEC III™ Ultra-Low-Emission Combustion Retrofit for the GE Frame 6B

Hanwha Power's LEC III combustion system is a field-proven ultra-low-emission retrofit for the GE Frame 6B gas turbine. LEC III replaces existing DLN 1.0 combustion hardware or diffusion system configurations with Hanwha Power's proprietary combustor design,delivering regulatory-compliant NOx and CO emissions without sacrificing operational flexibility or requiring changes to the turbine section.

LEC III performance (6B platform):

• Sub-5 ppm NOx on natural gas at baseload (LEC III)
• Sub-9 ppm NOx on natural gas (LEC NextGen, lower-cost option)
• 100+ global installations across B/E-class fleet (6B, 7EA, 9E frames)
• Compatible with GE 6581B legacy combustion systems
• Direct DLN 1.0 replacement or diffusion system conversion
• Extended turndown range while maintaining single-digit NOx and CO
• Support for natural gas and multi-fuel operation
• Designed for installation during a standard combustion inspection outage

‍LEC NextGen:

For operators who need emissions reduction but do not require the full LEC III package, Hanwha Power's LEC NextGen delivers sub-9 ppm NOx at a lower cost point. Same form factor and installation footprint as LEC III. Available for the 6B as well as 7EA and 9E platforms.
