[Abstract] [Problem to be solved] A C02 recovery apparatus which can significantly reduce the amount of steam and provide further improved energy efficiency is provided. [Solution] The apparatus includes: a flue gas cooling apparatus 14 for allowing cooling water 13 to cool a C02 and 02 containing flue gas 12 that is emitted from an industrial combustion facility 11 such as a boiler or gas turbine; a C02 absorber 16 having a C02 recovery section 16A for bringing the cooled C02 containing flue gas 12 and a C02 absorbing C02 absorbent 15 into contact with each other to remove C02 from the flue gas 12; and an absorbent regenerator 18 for releasing C02 from a C02 absorbed C02 absorbent 17 to regenerate the C02 absorbent. The apparatus further includes: a cleansing water divert line 51 for diverting partial cleansing water 19a of circulating cleansing water 19 that has been condensed in a cleansing section 16B in the C02 absorber 16; a first heat exchanger 52 disposed in the divert line 51 and in a boiler flue gas duct lla; and a superheated cleansing solution supply line 53 for directing, into the bottom portion of the absorbent regenerator 18, a superheated cleansing solution 19b having heat exchanged with a first heat exchanger 52.
