摘要： PROBLEM TO BE SOLVED: To provide a steam turbine, a steam turbine plant system, and an output increasing method for steam turbine capable of increasing the output by raising the performance of a high-low pressure integrated type turbine in which a high pressure part and a low pressure part are integrated and by utilizing its surplus steam effectively.
SOLUTION: A steam drainage hole 20 is provided in the prescribed place prior to the low pressure part L and a pressure regulating valve 35 is installed to discharge the steam as surplus for the low pressure part L from the steam drainage hole 20 by controlling the steam. The steam within the range of the rated pressure for the high pressure part H and surplus for the low pressure part L is introduced to the high pressure part H so as to perform high-load operation in the high pressure part H, while the surplus steam is introduced to the low pressure part L after discharged from the steam drainage hole 20. Thereby the output can be increased.
