1700℃ hydrogen combustion turbine development has been conducted in International Clean Energy Network Using Hydrogen Conversion Program (World Energy Network: WE-NET) under the contract between Japan Power Engineering and Inspection Corporation (JAPEIC) and New Energy and Industrial Technology Development Organization (NEDO) from middle of 1993 to end of March 1999. The goal of this program for hydrogen combustion turbine system is to achieve over 60% plant efficiency (HHV base) under 1700℃ turbine inlet temperature (TIT). Three turbine manufacturers such as Hitachi Limited (Hitachi), Mitsubishi Heavy Industries (MHI) and Toshiba Corporation (Toshiba) were selected and joined to perform the field tests under actual hydrogen-oxygen combustion condition with 1700℃ and 2.5MPa using newly built test facility located at Tashiro Town, Akita Prefecture. The target of this test project is to develop and verify cooling methods and design procedures for a 50MW pilot plant design. 104 minutes of the tests operation hours were recorded and technical approaches for 1700℃ turbine blades design were verified through the tests results and consequent analysis. This paper discusses mainly three items such as (1) the three kinds of test description of complete recovery steam cooling method, recovery steam cooling method and water cooling method, (2) results of the tests for correlation between design prediction and actual data and thermal barrier coating (TBC), and (3) these evaluation of these result and future development items.
