Title:
WATER TREATMENT AND METHOD OF WATER TREATMENT
Document Type and Number:
WIPO Patent Application WO/2006/109546
Kind Code:
A1
Abstract:
A water treatment for preventing the heat transfer surface of a boiler tube from general or local corrosion and attaining excellent heat transfer characteristics, which is composed of water as the main component, a film forming agent for forming a film on the heat transfer surface of a boiler tube, a deoxidizing agent, a scale inhibitor, and a pH regulator. By pouring this water treatment into boiler feeding, the prevention of a boiler tube from corrosion and the inhibition of scaling can be attained with good balance. According to the invention, a film for preventing the heat transfer surface of a boiler tube from corrosion is formed from the film forming agent; the oxygen dissolved in boiler feeding is removed with the deoxidizing agent; the scaling on the heat transfer surface of a boiler tube is inhibited with the scale inhibitor; and the pH of boiler feeding is regulated, whereby the heat transfer surface of a boiler tube can be prevented from general or local corrosion and excellent heat transfer characteristics can be attained.
