  • Publication number: 20220410062
    Abstract: Provided is a boiler plant including a carbon dioxide capture system. The carbon dioxide capture system has an absorbing-liquid regeneration device and an absorber. The absorbing-liquid regeneration device includes a regenerator, a first circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, and a second circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, a heat exchanger, a heater, and a switcher. The heat exchanger heats the absorbing liquid by exchanging heat between the absorbing liquid flowing through the first circulation line and steam from the 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 flows in the first circulation line and a second heating state in which the absorbing liquid flows in the second circulation line.

  • Publication number: 20220228515
    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.
