To provide a multipurpose thermal power plant system capable of capturing moisture and carbon dioxide in large quantities at a low cost from exhaust gas of an oxygen combustion boiler. To use an oxygen combustion boiler 1, an oxygen separator 6, a coal fuel feed apparatus 7, a steam turbine 2, a generator 3, denitrification equipment 10, a gas heat exchanger 11, a condensate cooler 12 for cooling exit gas of the gas heat exchanger with a condensate at an exit of a condenser which is a part of steam cycle water of the turbine, a dust collector 13, a desulfurizer 14, a cooling water-desalination apparatus 15, and a carbon dioxide liquefier 16, to utilize the characteristic that main components of exhaust gas of the oxygen combustion boiler 1 after combustion are carbon dioxide gas and steam, and to simultaneously capture moisture and carbon dioxide in the gas by cooling and compressing the exhaust gas. And to install a water feed system for utilizing the captured moisture as cycle water of a steam-water cycle of the steam turbine.
