PGT16 Aeroderivative Gas Turbines

The PGT16 gas turbine consists of the twin spool GE Aeroderivative LM1600 Gas Generator coupled with a rugged, industrial power turbine designed by GE Energy’s Oil & Gas businesses. The LM1600 Gas Generator is derived from the F404 turbofan aircraft engine.

The power turbine of the PGT16 gas turbine is identical to that of the PGT10 heavy duty, high efficiency gas turbine which has been in operation for more than half a million hours.

The power turbine shaft speed (7900 RPM) is optimized for direct coupling to pipeline, injection and process centrifugal compressors with a speed range that matches most operating requirements encountered in oil & gas applications. For generator drive applications the PGT16 synchronously coupled to a generator with a speed reduction gear is a highly flexible turbogenerator which can be operated as a simple cycle or in combined or cogeneration cycle applications with an electrical efficiency close to 50%.
