D202 コジェネレーション用セラミックガスタービンの研究開発

抄録

This paper describes a summary of the research and development program (FY1988-1998) of 300-kW class ceramic gas turbine (CGT302). This program has been promoted as a part of the New Sunshine Project funded by the Ministry of International Trade and Industry (MITI). The CGT302 has successfully accomplished the following that : i) it achieved 42.1% thermal efficiency at a turbine inlet temperature (TIT) of 1,396℃, ii) it obtained 31.7ppm NO_x emissions (O_2=16%) within the regulated value by the law at 1,350℃ TIT and iii) it accumulated more than two thousand hours operation at 1,200℃ TIT. Also, this paper presents an overview and a current status of the development program (FY 1999-2003) of 8,000-kW class hybrid gas turbine (HGT) in which both metal and ceramics are used in parts of high temperature to achieve high thermal efficiency and low emissions.
