    摘要： A heavy-duty gas turbine includes a compressor; a combustion liner; a turbine blade (7) in a single stage or multi-stages; and a turbine nozzle provided in correspondence to the turbine blade (7). The turbine blade (7) has a dovetail (10) secured to a turbine disk and has an overall length of not less than 180 mm, and it is made of a single-crystal Ni-base alloy whose γ phase is a single crystal. Operating gas temperature is not less than 1400 C, and metal temperature of a first blade is not less than 1000 °C under working stress.
