摘要： PROBLEM TO BE SOLVED: To provide a working fluid lead-in part structure of an axial flow turbine, capable of reducing a pressure loss in a steam channel and improving turbine efficiency and an axial flow turbine including the working fluid lead-in part structure.
SOLUTION: The steam lead-in part structure 10 includes: a lead-in pipe 20; a bent pipe 30 connected to the lead-in pipe 20 and formed so as to change the direction of the channel center line 50 to an axial direction of a turbine rotor 212; and an annular pipe 40 connected to the bent pipe 30 and leading steam to a first-stage nozzle 213a while spreading the steam in the circumferential direction of the turbine rotor 212. In the steam lead-in part structure 10, from the inlet of the lead-in pipe 20 toward an outlet of the annular pipe 40, steam channel widths Sa-1 to Sn-1 in a first direction intersecting with the channel center line 50 gradually increases and steam channel widths Sa-2 to Sn-2 in a second direction intersecting with the channel center line 50 and perpendicular to the first direction gradually decreases.
