LM6000 Sprint Aeroderivative Gas Turbines

Spray Inter-cooled Turbine System

Unlike most gas turbines, the LM6000 is primarily controlled by the compressor discharge temperature in lieu of the turbine inlet temperature. Some of the compressor discharge air is then used to cool high-pressure turbine components.

Sprint — which stands for "Spray Inter-cooled Turbine" - reduces compressor discharge temperature thereby allowing advancement of the throttle to significantly enhance power by 12 percent at ISO and greater than 30 percent at 90 °F (32 °C) ambient temperatures.
Features & Benefits

The LM6000 Sprint system is composed of atomized water injection at both low-pressure compressor (LPC) and high-pressure compressor (HPC) inlet plenums. This is accomplished by using a high-pressure compressor, eighth-stage bleed air to feed two air manifolds, water-injection manifolds and sets of spray nozzles, where the water droplets are sufficiently atomized before injection at both LPC and HPC inlet plenums.

Benefits of the 48.0 MWe LM6000 Sprint generator set include:

  • Up to 50 MW power generation
  • Full power in ten minutes
  • Baseload, cycling or peaking
  • Synchronous condensor capability
  • More than 75 turbines sold
  • More than 25,000 operating hours
  • Dual fuel capability (distillate or gas)
  • Easy on-site maintenance
