LM1600 Aeroderivative Gas Turbines

Best-in-Class Efficiency

The proven LM1600 gas turbine is made up of a dual-rotor gas generator and an aerodynamically coupled power turbine. It consists of a three-stage, low-pressure compressor; a seven-stage, variable-geometry, high-pressure compressor; an annular combustor with 18 individually replaceable fuel nozzles; a single-stage, high-pressure turbine; and a single-stage, low-pressure turbine. The gas generator operates at a compression ratio of 22 to 1.
Features & Benefits

The LM1600 incorporates variable geometry in its low-pressure compressor (LPC) inlet guide vanes and high-pressure compressor (HPC) stator vanes. Four electronically operated, variable-geometry bleed valves match the discharge airflow between the LPC and HPC.

In industrial applications the nozzles and blades of both the high-pressure turbine (HPT) and low-pressure turbine (LPT) are air-cooled and coated with CODEP, a nickel aluminide-based coating, to improve resistance to oxidation, erosion and corrosion. For marine applications the HPT nozzles are coated with a thermal barrier coating, the LPT nozzles are coated with CODEP and the blades of both the HPT and LPT are coated with PBC22.

The two-stage power turbine operates at a constant speed of 7,000 rpm over the engine operating range for generator drive applications and over a cubic load curve for mechanical drive applications.

The LM1600's experience base includes 146 units in service, which have accumulated more than 3.8 million operating hours at 97.4 percent documented availability, and 99.5 percent reliability.

The 13.7 MWe/19,120 shp LM1600 offers the following features:

  • Best-in-class efficiency
  • Fast start capability: cold iron to full power in ten minutes
  • Dry and wet technologies available for emissions control
  • Direct drive for power generation
  • Variable speed for mechanical drive.
