FINAL REPORT OF THE KEY TECHNOLOGY DEVELOPMENT PROGRAM FOR A NEXT-GENERATION HIGH-TEMPERATURE GAS-TURBINE

There is a strong demand for efficient and clean power-generating syst ems to meet recent energy-saving requirements and environmental, regul ations. A combined cycle power plant is one of the best solutions to t he above [1]. Tohoku Electric Power Co., Inc., and Mitsubishi Heavy In dustries, Ltd., have jointly developed three key technologies for a ne xt-generation 1500 degrees C class gas turbine, The three key technolo gies consist of: (1) high-temperature low-NOx combustion system, (2) r ow 1 turbine vane and blade with advanced cooling schemes, and (3) adv anced heat-resistant, materials; (2) and (3) were verified by HTDU (Hi gh Temperature Demonstration Unit). This paper describes the results o f the above-mentioned six-year joint development.
