Turbine inlet gas temperature and gas turbine capacity for power gen-eration system has been increased recently and 1300°C, 150MW Class gas turbine is now in the stage of practical use. At the present time, the net thermal efficiency of LNG fired combine cycle power generation plant using 1150°C class gas turbine has been reached 43%-44% and 47% is expected for 1300°C class gas turbine. Furthermore, the develop-ments of 1500°C class gas turbine have been started to get over 50% of the net themal effi-ciency in combined cycle power generation plant.
From the view point of global environmental problem and energy strategy in Japan, the importance of gas turbine in the power generation system should be increased. This paper describes the present status of high temperature gas turbine technology for power genera-tion.
