Abstract
A condenser for a steam turbine expels the oxygen-containing gas residing in the condensate passage in the hot well thereof by a scavenging steam. The oxygen-containing gas is expelled by the scavenging gas, which is introduced into the atmosphere in the condensate passage and arranged to flow counter to the condensate flow. The scavenging means includes a steam pipe attached in a vicinity of an outlet of the condensate passage in the hot well, and a valve device provided in the intermediate portion of the steam pipe.
