Abstract

PURPOSE:To prevent the corrosion of metal and to reduce the consumption of using water without carrying out replacement of circulating water by fresh water as usual method, by maintaining the rate of ions, such as HCO3<2->, Cl<->, Ca<2+>, etc., dissolved in the circulating water at a fixed relation. CONSTITUTION:Necessary ions are added to circulating water in cooling water system in the form of acid.alkali or salt, circulating between the cooling tower 2 and the heat exchanger 9 (exchanging heat with hot gas from the duct 16) through the pump 5, the flowmeter 7 and the pipes 8, 10, etc. and the ratio of ions dissolved in water, is maintained in the extent shown as the formula. On this occasion, it is good to add scale sticking inhibitor from the vessel 11 as usual. Thus, replacement by fresh water is made unnecessary and corrosion of metal is prevented so far as the above-mentioned ion constituent is maintained, even when the concentration of ions in circulating water is made more than several times that of necessary to purge usually.
