ABSTRACT:
In the operation of a main steam condenser of a steam turbine driven by a boiler and having a gland steam condenser, the gland steam condensate is normally fed from the gland steam condenser into the main condenser condensate. To avoid contamination of the main condenser condensate by oxygen-rich water, for at least part of the start-up period of the turbine, the gland steam condensate and other drain accumulating in the condenser is prevented from entering the main condenser condensate which is to be fed to the boiler. The gland steam condensate is fed to said main condenser and stored in a reservoir separate from the hot well thereof, to undergo de-aeration before being fed into the main condenser condensate.
