pH ADJUSTER OF BOILER WATER AND OPERATION METHOD OF BOILER

摘要

PROBLEM TO BE SOLVED: To provide a pH adjuster of boiler water which can prevent corrosion caused by a used chemical agent even when exerting a pH adjustment function and an electrical conductivity holding function enough, and can prevent water pollution by blow waste water of boiler water.;SOLUTION: The pH adjuster of boiler water used as a chemical agent for the pH adjustment and the electrical conductivity holding of boiler water for a boiler in which the water level of boiler water is detected by an electrode method includes a boron based compound in the chemical agent for the electrical conductivity holding of boiler water. The electrical conductivity of the aqueous solution of the boron based compound rises in proportion to the concentration. Moreover, the boron based compound does not cause the corrosion to a boiler can body or the like, and does not become a causative agent of water pollution to cause the eutrophication in the river or the like.;COPYRIGHT: (C)2012,JPO&INPIT
