A project aimed at developing a new combined plant having a target total efficiency of 55% is presently being advanced in Japan under the National Research and Development Program. This high efficiency combined plant essentially consists of a unique high efficiency reheat gas turbine, AGTJ-100A, and a conventional steam turbine. In order to achieve the high level thermal efficiency of 55%, this reheat gas turbine is designed with turbine inlet conditions which definitely exceed those of existing industrial gas turbines, namely a turbine inlet mean gas temperature of 1,300℃ and total pressure of 55 ata. (1) The high pressure turbine is operated under the most severe conditions among the components of the AGTJ-100A gas turbine and its performance and reliability greatly influence those of the whole combined plant. In order to verify the performance and reliability of the turbine a series of demonstration tests was conducted with use of high temperature turbine developing unit (HTDU), incorporating the high pressure turbine of the AGTJ-100A. This paper presents a general description of the HTDU and the aerodynamic and cooling characteristics of the HTDU turbine.
