| Research Abstract |
We conducted a demonstration experiment of steam generator and cooling facility in order to reveal the mechanism of scale prevention effect by electromagnetic treatment. Through the experiment, effectiveness of the electromagnetic treatment and the opposite-charging effect by electromagnetic field frequency were confirmed, along with the high effectiveness in practical use of this opposite charging phenomenon, which is remarkable when cationic water treatment chemicals is added. The water control standard value for electromagnetic treatment was revealed as well, controlling of which throughout the operation was also proven to inhibit scale adhesion to a large extent.
