15 GE Gas Turbines
The PGT25+G4 is a 34MW gas turbine consisting of an enhanced LM2500+ G4 Gas Generator
coupled with a 2-stage High Speed Power Turbine Module with increased flow capacity. High
efficiency and reliability together with fuel flexibility and low emissions are just some of the many
features that make this product the ideal choice for both mechanical drive and power generation in
pipeline and E&P applications both onshore and offshore. Upgrade kits for the installed base of
PGT25+ units are available to increase output power by 10%.
The gas generator of the PGT25+G4 is that of the PGT25+ upgraded for increased flow capacity of
the high pressure (HP) compressor and turbine.
The power turbine for the PGT25+G4 was developed based on GE’s extensive experience with heavy
duty gas turbines. The aerodynamic blading design provides high efficiency at both the design point
and at reduced speed.
