PROBLEM TO BE SOLVED: To provide a gas extraction system for a turbine plant, a gas extraction operating method, and a constructing method of the gas extraction system, capable of increasing the output of a steam turbine by maintaining a condenser at a high vacuum when a non-condense gas in the condenser is to be extracted.;SOLUTION: In the gas extraction system of a steam turbine plant extracts the non-condense gas from a condenser 13 of the steam turbine plant equipped with the steam turbine 11 which is supplied with steam from a steam source 10 and the condenser 13 to condense the steam ejected from the steam turbine 11, the condenser 13 is connected with a gas extractor to extract the non-condense gas, and the gas extractor is equipped at least with a steam ejector 32 to suck in the steam containing non-condense gas from the condenser using a driving steam supplied from the steam source 10 and a gas compressor 41 which is supplied with the steam sucked in by the ejector 32.;COPYRIGHT: (C)2011,JPO&INPIT
