Patent ID: 8347627

Claim:
A carbon-dioxide-capture-type steam power generation system comprising: a boiler producing a steam and an exhaust gas by combusting a fuel, the boiler having a flue through which the exhaust gas passes so as to discharge from the boiler; an absorbing unit receiving the exhaust gas from the boiler, the absorbing unit being configured to absorb the carbon-dioxide contained in the exhaust gas into an absorbing solution; a regenerating unit receiving the absorbing solution containing the carbon dioxide from the absorbing unit, the regenerating unit being configured to release the carbon dioxide gas from the absorbing solution absorbing the carbon dioxide and discharge the released carbon dioxide gas from the regenerating unit; a reboiler receiving a heating-medium as heat source, the reboiler producing a steam by heating the absorbing solution supplied from the regenerating unit and supplying the produced steam to the regenerating unit; a boiler-side heat exchanger provided between a economizer of the boiler and an air preheater in a flue, the boiler-side heat exchanger heating the heating-medium by the exhaust gas passing therethrough.
