From the standpoint of global environmental protection, improvement of thermal efficiency of gas turbine combined cycle (GTCC) is required. For this purpose, Mitsubishi Heavy Industries Ltd. has been participating in a national project aimed at developing 1700℃ gas turbine technology. In this project, Exhaust Gas Recirculation (EGR) system combustor is currently under development for NOx reduction at such a high temperature condition. For the EGR combustor development, the high-pressure combustion test with a test burner and the EGR simulated combustion test with full scale combustor were carried out. As the result, the qualitative NOx prediction tendency was verified by the high-pressure test. And, the full scale EGR simulated combustion test results indicate the development target (NOx:50 ppm, CO:10 ppm) is expected to be satisfied at the actual plant pressure condition.
