Abstract
According to one embodiment, a carbon-dioxide-recovery-type steam power generation system comprises a boiler that generates steam and an exhaust gas, an absorption tower that allows carbon dioxide contained in the exhaust gas to be absorbed in an absorption liquid, a regeneration tower that regenerates discharges a carbon dioxide gas from the absorption liquid, a reboiler that heats the absorption liquid of the regeneration tower, a turbine that is rotationally driven by the steam, a condenser that generates condensate by cooling steam exhausted from the turbine, a compressor that compresses the carbon dioxide gas, and a cooler that cools the carbon dioxide gas, which has been compressed by the compressor, while using a part of the condensate as cooling water. The reboiler is supplied with steam from the turbine and steam generated by the cooling of the carbon dioxide gas at the cooler.
