The steam turbine (1) includes the high-and-intermediate pressure turbine (2) of the single flow type, the intermediate-pressure turbine (4) of the single flow type, and the steam passage (6) that communicates a location on a part way of the steam flow inside the high-and-intermediate pressure turbine (2), to the steam inlet of the intermediate-pressure turbine (4). The high-and-intermediate pressure turbine (2) includes the high-pressure part (2A) on the steam inlet side and the intermediate-pressure part (2B) on the steam outlet side. The steam passage (6) feeds a part of the steam having passed through the high-pressure part (2A), from the location between the high-pressure part (2A) and the intermediate-pressure part (2B), to the intermediate-pressure turbine (4). |
