Updated EPRI report on Mitsubishi
Heavy Industries gas turbines includes information
on new M701F4 engine.
The latest upgrade to Mitsubishi’s F-class
50-Hz air-cooled engine, the M701F4, boasts an impressive
59.4% efficiency in combined-cycle operation (ISO,
LHV basis). The new model includes an improved compressor
airfoil design and longer blades for higher capacity,
higher pressure ratio, and improved efficiency. The
last stage turbine blading is lengthened and the exhaust
diffuser area is increased for reduced exhaust losses.
Firing temperature is raised about 45°F (25°C).
EPRI report 1012715 is one of a series that addresses
the design evolution, durability, and reliability
of all large heavy-duty and aeroderivative combustion
turbines. Such information will help owners and developers
make procurement decisions, assess combustion turbine
design features, and understand changes that drive
the technologies' technical risks. The report series
also offers insights into the state of product reliability
and maturity while providing a critical life-cycle
perspective. For more information, contact Dale Grace
