Heavy-Duty Gas Turbine M701F- Standard

In 1991, MHPS developed the M501F Series gas turbines for 60 Hz power generation. In the following year, it developed the M701F Series for 50 Hz power generation as a series with similar design. Since then, MHPS has continued to improve the design of F Series gas turbines. While introducing advanced elemental technologies and material technologies verified with the G Series with a proven track record, the F Series attains continuous performance enhancement. The gas turbine unit is based on the basic structure adopted in the early 1970s that has accumulated a track record of at least 40 years.

  • A compressor shaft end drive reduces the effect of thermal expansion on alignment

  • A rotor with simple single-shaft two-bearing support

  • An axial flow exhaust structure advantageous in combined cycle plant layouts

  • Horizontally split casings that facilitate field removal of the blades with the rotor in place

  • A rotor structure has bolt-connected discs with the torque pins in the compressor section and CURVIC couplings in the turbine section to ensure stable torque transmission
