for PGT10 two-shaft gas turbines are natural gas compression, centrifugal pump drive, process
applications, and power generation (including cogeneration) and offshore applications.
Design Information
17-stage axial flow compressor; pressure ratio 14.1:1
Single combustion chamber
Two-shaft turbine with two reaction stages
The gas turbine module on a single base plate includes the engine and the load gear; the
auxiliaries are installed on a separate base plate bolted to that of the gas turbine to form a
single lift on which the sound-insulated enclosure is mounted
The electric generator is installed on a concrete foundation to limit overall shipping
dimension
The package design is standardized for quick delivery, but custom applications can be
provided
The standard configuration, including the filters on top of the enclosure, is 30 by 8 by 13 ft
(9.1 by 2.5 by 4 m) and weighs 32 t
The combustion system is available in conventional and dry low emissions configuration to
satisfy the most stringent environmental regulations
Steam and water injection systems are available for nitrous oxide reduction and power
augmentation

PGT16
The PGT16 gas turbine consists of a twin spool LM1600 GE aeroderivative gas generator coupled
with a rugged, industrial power turbine designed by GE Oil & Gas. The LM1600's gas generator is
derived from the F404 turbofan aircraft engine, while the power turbine of the PGT16 gas turbine
is identical to that of the PGT10. The power turbine shaft speed (7,900 RPM) is optimized for
direct coupling to pipeline, injection, and process centrifugal compressors with speed ranges that
suit all operating conditions. For generator drive applications, the LM1600, coupled to its
