WATER PRESSURE SYSTEM OF STEAM PLANT

摘要

A water hydraulic system (100) includes a steam generator (4) for evaporating water and generating steam, a steam turbine (3) to be rotated by the steam generated in the steam generator (4), for generating motive power, and a steam condenser (5) for returning the steam passing through the steam turbine (3) to a water feed passage (6) as condensate. The water hydraulic system (100) includes a water hydraulic pump (9) to be driven by rotation of the steam turbine (3), for suctioning the condensate returned from the steam condenser (5) through a suction passage (8) and discharging the condensate, a water-hydraulically driven actuator (11) to be actuated by the pressurized water discharged from the water hydraulic pump (9), for driving an auxiliary machine, and a heat pump (20) for moving heat of the water flowing through the suction passage (8) to the water flowing through the water feed passage (6).
