Claim Text:
1. A steam turbine plant for supplying a steam consumer, comprising: a steam turbine comprising a feed steam device; and an inlet-steam collection line comprising an inlet-steam collection line section, wherein the inlet-steam collection line at an inlet-steam introduction point of the inlet-steam collection line section is introduced into an exhaust steam flow of the steam turbine, wherein the feed steam device comprises a changeover valve, wherein the feed steam device is connected upstream of the inlet-steam introduction point to the inlet-steam collection line section by the changeover valve, and wherein the feed steam device is selectively switched over by the changeover valve so that if an exhaust steam pressure is lower than a setpoint pressure in the inlet-steam collection line section, the inlet-steam collection line section is connected to the feed steam device for conducting a steam to the feed steam device and is disconnected between the changeover valve and the inlet-steam introduction point, and if the exhaust steam pressure is equal to or higher than the setpoint pressure, the inlet-steam collection line section is disconnected from the feed steam device.
