: One of the tests that I do for our condensed boiler water is for chloride. I have asked the chemical rep. what the results tell me and all he tells me is " it relates to cycles". Can anybody be a little more informative?
What is "condensed boiler water"? If you are talking about boiler water, chloride tests are run to determine how many cycles of concentration your boiler
water is at. Your cycles of concentration in boiler water have a limit you don't want to go beyond, or scaling will be more probable. Your chem. rep. should
explain this more fully to you. You can email me privately and I go over it further. Another reason chlorides is tested in the boiler is chlorides can accelerate
corrosion. The higher the chlorides the more accelerated corrosion can be, so we want to limit them to our set cycles of concentration. They can be used to determine
how much blowdown to perform on the boiler. Now, if you are talking about condensate, steam which has condensed back to water, measuring chlorides can tell you if
you have boiler water carryover, although measuring TDS is a better method. It's faster and easier and uses no expensive reagents. Hope this helps. Vern
