The research & development of a 300kW-class ceramic gas turbine has been administered by the New Energy and Industrial Technology Development Organization under a contract of the Agency of Industrial Science and Technology of the Ministry of International Trade and Industry as one of the R&D projects on energy conservation technology. In this program, the CGT301 is especially suitable for continuous full load application. The development of a ceramic heat exchanger for CGT301 has been carried out since 1988 as an application for gas turbine. In this paper, the progress of the development of the ceramic heat exchanger is described. The heat exchanger is three pass shell-and-tube type. The heat exchanger is to be operated at gas temperature over 825℃. Since the reliability is expected, the silicon-nitride ceramics is applied to its hot tube-bundle. In consideration of fabrication capability in the size of the ceramic tube-bundle, the heat exchanger was designed as the assembly of six identical modules. Tests were conducted only for a single module, and it was confirmed that the ceramic tube-bundle had reasonable structural reliability, and that the module gave a sufficient performance in terms of temperature effectiveness and pressure drop characteristics.
