<P>PROBLEM TO BE SOLVED: To provide a boiler water treatment agent for a pure water supply boiler and a water treatment method for a boiler, which achieve the sufficient corrosion inhibition in a steam generator even in any stage of ordinary water treatment, water filling to the start of an operation, the stop of the operation while retaining operating water after the stop of the operation in a boiler can, or the like, respectively. <P>SOLUTION: (1) The water treatment agent is used for a boiler in which the electrical conductivity of makeup water is ≤1 mS/m, and the boiler water treatment agent includes diol amines. (2) The water treatment method for a boiler is characterized in that, in a water treatment method for a boiler in which the electrical conductivity of makeup water is ≤1 mS/m, diol amines are allowed to exist in the boiler can. <P>COPYRIGHT: (C)2013,JPO&INPIT |
