A carbon-dioxide-recovery-type steam power generation system comprises a boiler that generates steam through the combustion of fuel and generates an exhaust gas (5), an absorption tower that is supplied with the exhaust gas from the boiler (6), and allows carbon dioxide contained in the exhaust gas to be absorbed in an absorption liquid, a regeneration tower that is supplied with the absorption liquid having absorbed carbon dioxide from the absorption tower, discharges a carbon dioxide gas from the absorption liquid, and discharges the carbon dioxide gas, a reboiler (41) that heats the absorption liquid discharged from the regeneration tower and supplies generated steam to the regeneration tower, a turbine (21) that is supplied with steam from the boiler and is rotationally driven, a condenser that generates condensate by cooling steam exhausted from the turbine (26), a condensate pump that sends the condensate to a line, a water supply pump (34) that is provided on the line and supplies water to the boiler, a compressor (53) that compresses the carbon dioxide gas, and a cooler (55,56) that is supplied with a part of the condensate and cools the carbon dioxide gas, which has been compressed by the compressor, while using the condensate as cooling water. The reboiler is supplied with steam (60) that is exhausted from the turbine and steam that is generated by the cooling of the carbon dioxide gas at the cooler.

According to one embodiment, a carbon dioxide recovering apparatus includes a flow distributor dividing the first rich solution discharged from an absorbing tower into a second rich solution and a third rich solution, a reheat exchanger heating the second rich solution with a lean solution discharged from a releasing tower as a heat source, a heating unit heating the third rich solution with a carbon dioxide containing steam to be released from the releasing tower as a heat source, a gas-liquid separator separating the carbon dioxide containing steam used to heat the third rich solution into carbon dioxide and condensate water, a measuring unit measuring an amount of the condensate water in the gas-liquid separator, and a controller. The controller controls a flow dividing ratio in the flow distributor based on a change in the amount of the condensate water measured by the measuring unit.
