Abstract
A steam turbine plant includes a high-medium pressure turbine having a high-pressure turbine section provided at one end portion in an axial direction and a medium-pressure turbine section provided at the other end portion; a low-pressure turbine disposed coaxially with the high-medium pressure turbine; a condenser configured to cool steam used in the low-pressure turbine to condense the steam into condensate; and a feed-water heater configured to heat the condensate with steam discharged from the high-pressure turbine section. The plant also includes a low-pressure moisture separating and heating device configured to remove moisture of steam discharged from the medium-pressure turbine section, and to heat the steam with a part of steam to be sent to an inlet portion of the high-pressure turbine section and a part of steam to be sent to an inlet portion of the medium-pressure turbine section from an outlet portion of the high-pressure turbine section.
