LM2500™
LM2500™
The LM2500™ is an industrial gas turbine made by GE and is based on the CF6-6 commercial aircraft engine. MTU has been providing maintenance services for it since 1981. Unlike the LM6000™ model, the LM2500™ features a single-rotor gas generator, which can be aerodynamically coupled to a power turbine. It comprises a 16-stage compressor, an annular combustor, a two-stage high-pressure turbine, and in some cases a high-performance power turbine. The LM2500™ is the most widely used gas turbine in the 20–25 megawatt power category.
The LM2500+™ and LM2500+G4™ gas turbines are uprated versions of the LM2500™ and offer 30.20 MW and 36.98 MW of power, respectively.
MTU’s involvement in the LM2500TM
MTU manufactures the disks for the front two high-pressure turbine stages and provides maintenance services for the LM2500TM at MTU Maintenance Berlin-Brandenburg.
