Abstract

A thermal power plant comprising: a boiler 1 for burning fossil fuel to generate steam, a steam turbine 100 including a high-pressure turbine 3, an intermediate-pressure turbine 7, and a low-pressure turbine 10 which are driven by steam generated in the boiler 1, an absorber 24 for absorbing and capturing CO 2 contained in boiler exhaust gas discharged from the boiler 1 in an absorbing liquid, a desorber 21 for circulating the absorbing liquid between the desorber 21 and the absorber 21 and separating CO 2 from the absorbing liquid that has absorbed CO 2 , a reboiler 18 for feeding a heating source for separating CO 2 from the absorbing liquid to the desorber 21, a steam pipe system for feeding steam taken out from the high-pressure turbine 3 and the intermediate-pressure turbine 7 to the reboiler 18, and a steam feed source switching device which is installed in the steam pipe system for switching a steam feed source for feeding steam to the reboiler 18 between the intermediate-pressure turbine 7 and the high-pressure turbine 3 so as to satisfy a steam pressure required by the reboiler 18 while the steam turbine 100 is under a partial load operation.
