Abstract
A gas turbine plant includes a gas turbine, an exhaust line, an exhaust heat recovery boiler that generates steam due to heat of exhaust gas and guides the exhaust gas to the exhaust line, a carbon dioxide recovery device that recovers carbon dioxide contained in the exhaust gas, a heat exchanger that cools the exhaust gas to a temperature set in advance, and a circulation line that branches from a position between the carbon dioxide recovery device and the heat exchanger and is connected to an inlet of the gas turbine. The carbon dioxide recovery device has an absorption tower that absorbs carbon dioxide contained in the exhaust gas by causing the exhaust gas at the set temperature and an absorption liquid to come into contact with each other. The heat exchanger is formed of a material having higher corrosion resistance than a material forming the exhaust heat recovery boiler.
