Abstract
Through analysing various diagnostic methods for circulating water stability in power plants
it is determined to use the stability index method for on-line monitoring the circulating water quality stability.By using the potential titrimetric method
the alkalinity of water sample has been measured.Through tests in the laboratory
the main affecting factors in alkalinity measurement using potential titrimetric method have been found
and the optimal test condition being given.Results of tests show that the stability index method to be used for determining the stability of circulating water
and the potential titrimetric method to be used for measuring the alkalinity of water sample
as well as using them in developling an on-line monitoring system for circulating water stability all are feasible.
