Combined cycle (CC) operated is known as a highly effective power generation system and operated widely in the world. However, decrease of power output of Gas turbine (GT) at high ambient temperature is the problem to be solved. It is desirable to understand the characteristics of the system for effective operation. We installed a small scale CC system with a micro gas turbine (μGT) to improve the system design. Optimum start up condition is adjusted by changing of fuel/air ratio. Low fuel ratio is more preferable compared with high fuel ratio.
