WIPO Patent Application WO/2017/199660
Kind Code:
A1
Abstract:
A steam turbine plant equipped with: a high-intermediate pressure turbine (21) at one end of which in the axial direction a high-pressure turbine unit (25) is provided, and at the other end of which an intermediate-pressure turbine unit (26) is provided; low-pressure turbines (22, 23) arranged coaxially with the high-intermediate pressure turbine (21); condensers (33, 34) that cool steam used in the low-pressure turbines (22, 23), thereby condensing the steam and converting the steam to condensate water; and a second high-pressure water supply heater (50) that heats the condensate water by means of steam discharged from the high-pressure turbine unit (25).
