Patent ID: 8567196

Claim:
A steam turbine power plant, comprising: a steam turbine facility which comprises a boiler having a super heater and at least one reheater, a first steam turbine driven by main steam delivered from the super heater, a second steam turbine driven by steam delivered from the reheater, the reheater reheating steam exhausted from the first steam turbine, a third steam turbine driven by steam which is exhausted from the second steam turbine, a generator coupled with at least the third steam turbine, a steam condenser condensing steam exhausted from the third steam turbine into condensate, a feed water heater provided in a water supply system between the steam condenser and the boiler to heat feed water delivered from the steam condenser, a heat collecting steam generator generating steam from part of the condensate by utilizing heat of sunlight, and a fourth steam turbine driven by at least steam delivered from the heat collecting steam generator; and a carbon dioxide collecting facility which comprises an absorbing tower having an absorbing liquid configured to absorb carbon dioxide contained in combustion gas from the boiler, a recovery tower configured to heat the absorbing liquid by utilizing heat of steam exhausted from the fourth steam turbine so as to discharge the carbon dioxide from the absorbing liquid, and a collecting apparatus collecting carbon dioxide discharged in the recovery tower.
