Method for preventing contamination of a heat exchanger using an active oxygen generating polyaniline film.

摘要

A low cost method for preventing contamination of a heat exchanger whereby a film of polyaniline is formed on the metal surface of the heat exchanging portion. Upon operation condensed water makes contact with the film and oxygen dissolved within the water becomes active. The active oxygen reacts with organic substances within the water causing them to decompose. Thus the amount of organic substances adhered to the surface of the heat exchanger can be reduced. The oxygen generating capacity of the film can be regenerated by drying the surface of the metal base material.
