6F, 501D, OP16, and Frame 5 Gas Turbine Upgrades

6F, 501D, OP16 and Frame 5

Hanwha Power delivers aftermarket gas turbine solutions for frame models beyond the most common fleets. Whether your unit is a GE 6F,Siemens/Westinghouse 501D, OP16, or GE Frame 5 (5001), our combined capabilities cover combustion system retrofits, hot gas path component upgrades, rotor services, field support, and long-term service agreements. Hanwha Power provides combustion technologies including LEC III™ and FlameSheet™, and hot gas path components, rotor services, field services, and complete outage support

Why Upgrade Legacy Gas Turbine Frames?

Upgrading older frames with modern technology delivers clear, long-term value:

• Improved Performance – Boost power output, reduce emissions, and enhance fuel efficiency.
• Increased Reliability – Minimize unplanned downtime by replacing aging components with proven, high-reliability upgrades.
• Extended Operational Life – Modernization delays capital investment and maximizes the value of existing assets.
• Enhanced Safety – Integrate newer safety standards and reduce risk for operators and facilities.
• Cost Efficiency – Lower lifecycle costs by extending maintenance intervals and improving part durability.

Proven Upgrade Technologies

Our engineering-driven upgrades combine innovation with field-proven results. Key solutions include:

FlameSheet: Fuel-Flexible Combustion System

FlameSheet is a combustion system designed for fuel flexibility, emissions compliance, and extended inspection intervals up to 32,000 factored hours. FlameSheet supports natural gas, hydrogen blends, and alternative fuels within a 30% Modified Wobbe Index (MWI) operational range.  NOTE: FlameSheet availability varies by frame type. Contact Hanwha Power to confirm applicability for your specific installation.

LEC III: Low-Emission Combustion System

A low-emissions combustion system delivering 3–5 ppm NOx and single-digit CO. A reliable option for operators looking to meet tight emissions regulations. Learn more about LEC III™

LEC NextGen

An advanced version of LEC III™, offering enhanced durability and consistent <9ppm NOx even under variable load conditions. Compatible with 6B, 7E/EA, 9E, and legacy 7B units.

HGP Parts: Hot Gas Path Components (in Rheden)  

Hanwha Power manufactures and supplies hot gas path components for these frame types,including inner barrel hardware, compressor blades, and turbine section components. All HGP parts are designed for OEM-level interchangeability with improved materials, sealing, and cooling. Contact Hanwha Power for HGP component options and availability.
