PSM delivers retrofit and upgrade solutions that enhance the performance, efficiency, and emissions profile of existing gas turbines, including GE 7F, 9F, 6B, 7EA, 9E, and Siemens/MHI 501Fframes, as well as legacy B/E-class and Frame 5 platforms. Our combustion technologies and hot gas path upgrade packages allow operators to maximize output, extend inspection intervals, meet evolving emissions regulations, and lower total lifecycle costs without replacing the turbine.
FlameSheet™ Advanced Combustion System for Gas Turbines
A can-annular combustor system that expands the operating range by up to 30% while maintaining single-digit NOx and CO emissions, even with hydrogen and alternative fuel blends. FlameSheet supports inspection intervals up to 32,000factored hours and is available for GE 7F, 6B, Frame 5, and other GE,Siemens-Westinghouse, and MHI platform.
Learn moreLEC III™ Ultra Low Emission Combustion System
Field-proven since1999, LEC III delivers sub-5 ppm NOx on natural gas with single-digit CO.Compatible as a drop-in retrofit for GE DLN1 combustion systems on 6B, 7E/EA,9E, and legacy 7B platforms. Over 70 installations worldwide. Greater turndown capability and lower combustion dynamics than OEM DLN1 systems.
Learn moreGTOP: Gas Turbine Optimization Package
GTOP combines hot gas path component upgrades with combustion system improvements to deliver a comprehensive performance solution. GTOP packages for the 7F have achieved 32,000+ equivalent operating hour inspection intervals. Also available for B/E-class frames. Each package is engineered to specific operator goals, from peak firing output to part-load efficiency.
Learn moreSequential Fuel Injection (SFI)
Expand flexibility with extended turndown capability (down to 35%) using SFI, compatible with LEC III™, DLN-1, and IBH systems. Ideal for operations with fluctuating demand or emissions constraints.
Learn moreAuxiliary Upgrades
Boost plant efficiency and reliability with enhancements like wet compression, inlet bleed heat, anti-icing, and exhaust bleed systems. These upgrades reduce fuel consumption while maximizing unit performance.
