    摘要： 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.
