From the view point of high efficiency of 100MW class gas turbine power generator which meets the needs for short or medium term at power industry, Advanced Humid Air Turbine (AHAT) is suitable, because more than 51 percent of net thermal efficiency and more than 15 percent of CO_2 reduction are achievable. In order to make practical use AHAT, we have been developing recuperator which has an enough durability against high thermal stress by start-up, shutdown and quick transient operation at high temperature and high humidity condition.
