Abstract
A steam seal dump re-entry system delivers steam dump flow to an LP steam turbine. The system includes a steam seal header receiving steam leaking from turbine end seal packings, and a desuperheater receiving and cooling the steam from the steam seal header. The desuperheater outputs cooled steam. A temperature sensor is disposed downstream of the desuperheater and detects a temperature of the cooled steam. A flow control circuit communicating with the temperature sensor selectively delivers the cooled steam to at least one of the condenser and to the LP steam turbine depending on the temperature of the cooled steam.
