A CO2 recovering apparatus includes a CO2 absorber that brings flue gas containing CO2 into contact with CO2 absorbent to reduce the CO2 contained in the flue gas; and a regenerator that reduces CO2 contained in rich solvent absorbing CO2 to regenerate the rich solvent, so that lean solvent that is the CO2 absorbent having the CO2 reduced in the regenerator is reused in the CO2 absorber. The CO2 recovering apparatus further includes a controller that detects a difference between a gas temperature (T1) of the flue gas guided into an entrance of the CO2 absorber and a gas temperature (T2) of the gas exiting the CO2 absorber, and an absorbent concentration (X (Vol%)) of the CO2 absorbent; and controls to adjust an amount of water contained in the gas depending on the gas temperature difference between the gas entering and the gas exiting the CO2 absorber and to keep an absorbent concentration of the CO2 absorbent within a set range (e.g., X0~10 % in a relative ratio).
