Claim 0:
1. A gasification gas treatment facility for treating a gasification gas obtained by gasification of a fuel, comprising:
a cleaning facility that produces a purified gas by making the gasification gas come into contact with scrubbing water;
a first heat exchanger for performing heat exchange between the purified gas and steam;
a second heat exchanger for performing heat exchange between the gasification gas and at least condensed water produced by the heat exchange in the first heat exchanger;
a circulation system for circulating a circulating fluid including at least one of the steam or the condensed water between the first heat exchanger and the second heat exchanger;
a first steam system that supplies the steam to the circulation system;
a steam extraction system that extracts the steam from the circulation system;
a pressure gauge that measures a pressure of the circulation system; and
a flow rate adjustment valve, disposed in the steam extraction system, that adjusts a flow rate of the steam flowing through the steam extraction system based on the pressure measured by the pressure gauge,
wherein the second heat exchanger includes an interior space for storing the condensed water which has flowed through the circulation system.
