抄録

MHPS has successfully developed the highly-efficient M501J, which achieved the world's first turbine inlet temperature of 1600°C, and started verifying operations using the verification facility in the MHPS Takasago Works in 2011. Thereafter, the M501J has been delivered all over the world, and have accumulated more than 750,000 Actual Operating Hours. In addition, to further improve the efficiency of the gas turbine combined cycle power generation (GTCC) and enhance the operability, we replaced the steam-cooled system for the cooling of the combustor and developed a new enhanced air-cooled system. This paper presents the development and operational situation of the state-of-the-art, high-efficiency gas turbine of MHPS and the development of the next-generation 1650°C class JAC (J Air Cooled) gas turbine using an enhanced air-cooled system as the core technology based on the technology adopted for the M501J.
