A boiler system including an electric power generation system having a boiler 1, a steam turbine 23 for generating electric power by steams which received heat at a boiler, a condenser 24 provided at the downstream thereof for condensing the steams, and a heater 26 for heating condensed water by steams extracted from the steam turbine and, further, a CO 2 capture system of sorbing and capturing a CO 2 gas in an exhausted gas exhausted from the boiler by using a solid CO 2 sorbent, and a chimney 7 of exhausting an exhaust gas in the CO 2 capture system after recovery of CO 2 or an exhaust gas exhausted from the boiler, in which the temperature of a fluid concerned with the boiler system is increased by using the exhaust gas exhausted from the CO 2 capture system.
