Abstract

PURPOSE: To provide an apparatus for preventing corrosion of heat exchanger tubes, wherein an anticorrosive agent is cycled through a closed loop comprising the heat exchanger and a cycle loop thereby the amount of the anticorrosive agent used for other parts can be lowered.
CONSTITUTION: A method of preventing corrosion of a heat exchanger 2 is effected in such a manner that separation valves at the inlet and the outlet for the heat exchanger 2 are closed so that the heat exchanger is isolated. Then a valve 7 for preventing bypassing of cooling water is opened, a pump 1' for cycling the anticorrosive agent is operated, and the anticorrosive agent is injected from an anticorrosive agent injection port 3. The anticorrosive agent flows into the heat exchanger 2 by the action of the pump 1', forms an anticorrosive film on each heat transfer tube of the heat exchanger 2, and exits the heat exchanger 2. Thereafter the anticorrosive agent flows into the cycle loop 4 via the inlet or outlet of the heat exchanger 2, the pressure thereof is again raised by the pump 1', and again returns to the inlet or outlet of the heat exchanger 2. Consequently the anticorrosive ageng is not carried to other parts, so that the amount of the anticorrosive agent used is small, and the probelm can be obviated which causes the cooling water discharged outside to be colored.
