METHOD OF MONITORING CONTAMINATION OF COOLING WATER LINE AND METHOD OF CONTROLLING CHEMICAL FEED

摘要

PROBLEM TO BE SOLVED: To provide a method of discriminating whether the contamination of a cooling water line is caused by slime or a scale, and a method of feeding chemicals according to a result thereof.;SOLUTION: In a method of monitoring the contamination of a cooling water system for circulating and supplying cooling water to a heat exchanger, the detection of fouling based on LTD or ATD of the heat exchanger and the detection of adhesion of slime by a slime sensor are executed, and whether the fouling is slime or a scale is discriminated according to the presence or absence of the adhesion of the slime by the slime sensor when the adhesion of fouling is detected on the basis of LTD or ATD.;COPYRIGHT: (C)2014,JPO&INPIT
