Application of J-Series technologies
High-efficiency high-operability gas turbines for 50 Hz power
generation incorporating J-Series technologies
In 1991, Mitsubishi Power 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, Mitsubishi Power 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.

Overall Design
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. Its main
features are as follows:
• A compressor shaft end drive reduces the effect of thermal
expansion on alignment
• A rotor with simple single-shaft two-bearing support
• 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
• 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
Compressor
Variable inlet guide vanes ensure operational stability at the start-up and
enhanced performance at partial load in combined cycle operation.
Combustor
A premixing low NOx combustor is composed of one pilot burner and eight
main burners that surround it. The compressor has an air bypass
mechanism that enables fuel-air ratio regulation in the combustion region.
Turbine
Rotating Blades at the first two stages are free-standing, while those at the
third and fourth stages are integral shroud blades.
Stationary vanes are supported by blade rings that are independent at
individual stages to prevent turbine casings from being affected by thermal
expansion.
