The present invention relates to a boiler feedwater system for a ship having an oil inflow detecting means which detects if oil is mixed with condensate water collected from a steam-using device in a ship to block a flow into a feed filter tank. According to the present invention, the boiler feedwater system for a ship having an oil inflow detecting means comprises: a boiler (1) to produce steam; a feedwater pipe (2) to transport steam produced by the boiler to a steam-using device in a ship; the steam-using device (3) to exchange heat with the steam supplied from the feedwater pipe; a collection pipe (4) to collect condensate water resulted from exchanging heat with the steam-using device; a feed filter tank (5) to receive a condensate water from the collection pipe to filter out foreign substances, and then store the condensate water; a transport pump (6) to transport the condensate water stored in the feed filter tank to the boiler; an oil inflow detecting means (7) installed in one point of the collection pipe on a front end of the feed filter tank to detect if oil is in the condensate water; and an electronic three-way valve to change a flow passage of the condensate water flowing in the collection pipe connected to the feed filter tank if the oil is detected by the oil inflow detecting means. |
