摘要： PROBLEM TO BE SOLVED: To improve efficiency in the whole plant, by reducing an energy loss in a turbine inlet part, even if a drift current is caused in a steam flow by an elbow pipe part.SOLUTION: A steam turbine includes a double current type turbine having a first turbine step part 12a and a second turbine step part 12b, and a turbine inlet part 1 arranged between the first and second turbine step parts, and a crossover pipe 3 having an elbow part 11 for downwardly bending a steam flow flowing toward the second turbine step part side from the first turbine step part side in the pipe, toward the turbine inlet part. In a steam flow passage where steam distributed in the rotor axial direction in the turbine inlet part 1, flows toward the first turbine step part 12a and the second turbine step part 12b, at least the partial cross-sectional area of the steam flow passage of the steam flowing to the second turbine step part 12b, is formed larger than the cross-sectional area of the steam flow passage of the steam of flowing to the first turbine step part 12a.
