Verification of 1650℃ class JAC gas turbine

抄録

Mitsubishi Power, Ltd. (Mitsubishi Power) has focused on developing highly efficient power generation equipment to contribute to the worldwide efforts to reduce global warming and supply stable power. JAC gas turbine with turbine inlet temperature of 1650℃ was developed to meet the market needs for larger plant output and higher efficiency. For the purpose of achieving 1650℃ class gas turbine and high efficiency, key technologies such as enhanced air-cooled system, thicker advanced thermal barrier coating (TBC) and high pressure compressor were applied in JAC gas turbine. The verification of these technologies and long-term reliability of JAC gas turbine has been conducted by actual operation of JAC gas turbine at in-house verification combined cycle power plant, called T-point 2, since January 2020. This paper describes the verification results.
