摘要： PROBLEM TO BE SOLVED: To provide a new scale inhibitor which has a high scale inhibiting effect.
SOLUTION: The scale inhibitor is a scale inhibitor for a steam generation system, and contains at least a polyacrylate having a molecular weight of 20,000 or more and 70,000 or less. As a method of inhibiting scale using the scale inhibitor is remarkably excellent in the scale inhibiting effect in comparison with conventional scale inhibiting technology, it can suitably be used for the steam generation system such as a boiler. As the scale inhibiting effect can be exhibited even when the concentrations of hardness components and silica are higher than conventional, high concentration operation where blow water is reduced can be carried out, thereby reducing energy cost.

When the measurement result exceeds a reference value, a signal is transmitted from the control means 20 to valves 5a, 7a, 8a, and an alarm is transmitted to a control center. Thus, the valve 5a is closed and the valve 7a is opened. The condensation discharged from the steam use facility 4 is not supplied to raw water piping 1 and is discharged to outside of a system from water discharge piping 7. An opening of the valve 8a is increased, so as to increase the chemical feeding amount of water treatment agent from piping 8. COPYRIGHT: (C)2010,JPO&INPIT
