Abstract

PURPOSE: To automatically remove the scale to enable the continuous operation by using as a heat-exchange tube a resin coated tube and injecting high-pressure water in water within the tank.
CONSTITUTION: Water having a temperature Th and containing impurities is placed in the tank 1. On the other hand, water having a temperature Tl(Tl<Th) is passed in the heat-exchange tube 2. This heat exchange tube 2 is selected to a resin-coated heat exchange tube coated at its outer surface with a high-molecular resin. Further, an injection nozzle header tube 16, and an injection nozzle 17 are arranged in water within the tank 1, and water is injected against the resin- coated metal tube 2 from the injection nozzle 17. By this procedure, the scale adhering to the surface of the tube 2 is removed, and since the scale adheres to the tube 2 in an easily peeled off manner by the resin coating, the scale can be easily removed.
