摘要： This gas turbine plant is provided with: a gas turbine; an exhaust line; a waste heat recovery boiler that generates steam from the heat of exhaust gas and guides the exhaust gas to the exhaust line; a carbon dioxide recovery device that recovers carbon dioxide included in the exhaust gas; a heat exchanger that is disposed between the waste heat recovery boiler and the carbon dioxide recovery device and that cools the exhaust gas to a predetermined temperature; and a circulation line that branches from a position between the carbon dioxide recovery device and the heat exchanger and is connected to an entrance of the gas turbine. The carbon dioxide recovery device comprises an absorption tower that absorbs carbon dioxide included in the exhaust gas by bringing the exhaust gas at the predetermined temperature and an absorbing liquid into contact with one another. The heat exchanger is formed from a material with greater corrosion resistance than a material from which the waste heat recovery boiler is formed.

摘要： Provided is a boiler plant including a carbon dioxide removal facility. The carbon dioxide removal facility has an absorbing-liquid regeneration device and an absorption device. The absorbing-liquid regeneration device has: a regeneration tower; a first circulation line in which an absorbing liquid is taken out from the regeneration tower and is returned to the regeneration tower; a second circulation line in which the absorbing liquid is taken out from the regeneration tower and is returned to the regeneration tower; a heat exchanger; a heater; and a switcher. The heat exchanger heats the absorbing liquid through heat exchange between the absorbing liquid flowing in the first circulation line and steam from a boiler. The heater heats the absorbing liquid flowing in the second circulation line. The switcher switches between a first heating state in which the absorbing liquid is made to flow in the first circulation line and a second heating state in which the absorbing liquid is made to flow in the second circulation line.
