The development of gas turbines, which Mitsubishi Heavy Industries, Ltd. (MHI) has
continued to pursue, contributes to society in terms of global environmental conservation and a
stable energy supply. MHI leverages its abundant gas turbine operation experience and takes
advantage of its extensive advanced technologies research on "Component Technology
Development for 1,700°C Class Ultra-High-Temperature Gas Turbines" for the national project.
The company has been participating in this project since 2004. Recent years' achievements
includes the demonstration of a gas turbine combined cycle (GTCC) efficiency in excess of 61.5%
by increasing the turbine inlet temperature to the 1,600°C class in the M501J in 2011(1)(2)(3). The
M701F5 incorporates "J" gas turbine technologies, already applied to actual equipment, for
efficiency improvement. It also applies air-cooled combustor technologies successfully validated in
the GAC, for increased flexibility. The delivery of the initial unit is scheduled for 2014. This paper
explains the features and development status of M701F5 gas turbine.
