摘要： According to one embodiment, a carbon-dioxide-recovery-type steam power generation system comprises a boiler that produces steam and generates an exhaust gas, a first turbine that is rotationally driven by the steam, an absorption tower allows carbon dioxide contained in the exhaust gas to be absorbed into an absorption liquid, a regeneration tower that discharges the carbon dioxide gas from the absorption liquid supplied from the absorption tower, a condenser that removes moisture from the carbon dioxide gas, discharged from the regeneration tower, by condensing the carbon dioxide gas using cooling water, a compressor that compresses the carbon dioxide gas from which the moisture is removed by the condenser, and a second turbine that drives the compressor. The steam produced by the cooling water recovering the heat from the carbon dioxide gas in the condenser is supplied to the first turbine or the second turbine.
