The invention discloses a feedwater pressure stabilizing and deoxidizing device and a marine steam power system. The feedwater pressure stabilizing and deoxidizing device comprises a constant pressuredeoxidizing tank, a feed water pump, and a feed water pump driving steam turbine, wherein the constant pressure deoxidizing tank is provided with a condensed water inlet pipe, a condensed water outlet pipe, a steam outlet pipe, a steam inlet pipe and a connecting pipe; and the constant pressure deoxidizing tank is connected to an outlet of the feed water pump driving steam turbine through the steam inlet pipe, is connected to an outlet of a condensate pump through the condensed water inlet pipe, is connected to an inlet of the condensate pump through the condensed water outlet pipe, and is connected to air through the steam outlet pipe. According to the feedwater pressure stabilizing and deoxidizing device provided by the invention, exhaust steam of the feed water pump driving steam turbine is used as the heat source of the constant pressure deoxidizing tank by using a heating and deoxidizing method; condensed water returned from the outlet of the condensate pump is used as the cold source of the constant pressure deoxidizing tank; and the constant pressure deoxidizing tank is connected to an inlet of the feed water pump through the connecting pipe, so that feedwater can be deoxidized, and the pressure fluctuations at the inlet of the feedwater pump can also be effectively suppressed.
