Mitsubishi Hitachi Power Systems, Ltd. (MHPS) is progressing with the development of
highly-efficient gas turbine combined cycle (GTCC) power generation with the Research &
Innovation Center of Mitsubishi Heavy Industries, Ltd. (MHI) in order to make a contribution to
the conservation of the global environment and the stable supply of energy. We developed the
M501J type, the world's first highly-efficient machine with a turbine inlet temperature of 1600°C
by utilizing the development results acquired in the national project "Development of Element
Technologies for CC Efficiency 57% Gas-Turbine," which we took part in from fiscal 2004. The
operational results of the developed machine have been accumulated.1 For the next generation
GTCC, we are currently working on the development of elemental technologies for a 1650°C-class
air-cooled gas turbine such as a closed (next generation) air cooling system that was researched in
collaboration with Tohoku Electric Power Co., Inc. with the aim of increasing the turbine inlet
temperature. This paper presents the current progress in the development of analysis and
measurement technologies in the combustion and heat transfer field for the realization of the next
generation GTCC.
