PURPOSE:To enhance the thermal efficiency of the whole turbine system by providing a bleeder turbine which bleeds air from a high pressure turbine to a medium pressure turbine, with a line which sends excess steam in the medium pressure line to the low pressure turbine side. CONSTITUTION:While steam is sent from a high pressure turbine 1 via a regulation valve 18 to a low pressure turbine 3, a par of the steam is sent to a medium pressure line 10 via a check valve 7 and a bleeding line 11. A feeding line 14 which has a check valve 6, a filter 5 and an emergency cut-off valve 4 is disposed in parallel with the bleeding line 11. When the steam is critically oversupplied in the medium pressure line 10, the surplus steam is fed for application into the low pressure turbie 3 via the feeding line and the regulation valve 18. |
