Water Treatment

Chloride is chosen as the indicator for cycles of concentration because, 1) it is always present in the makeup water, 2) it does not change character when heated, 3) it is not affected by chemical treatment, and 4) like the other dissolved solids, it does not leave the water in the boiler when steam is produced.

Water Handbook - Preboiler & Industrial Boiler Corrosion

The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be maintained between 8.5 and 9.5 for system corrosion protection. In order to minimize boiler system corrosion, an understanding of the operational ...

Boiler Water Treatment Chemicals, Feed, and Control

to the boiler, the boiler sulfite residual may not show a big change as oxygen is released into the steam or corrodes the boiler before it is reduced chemically. Dissolved oxygen testing in the feedwater would be the best tool to insure consistently low dissolved oxygen levels and adequate chemical feed and control.

Boiler Chemical Treatment

Chloride (not to be confused with chlorine), does not leave with the steam, is used to determine the number of "cycles of concentration" in your boiler water. If your fresh or "make-up" water chloride level is 10 ppm and boiler water chloride level is 50 ppm, the boiler water is at 5 cycles of concentration. Five is a pretty good number for ...

Chlorides & Steam — Heating Help: The Wall

Sharing what I've learned with commercial sized 200 and 300 HP steel steam boilers, and agreeing with Glen from Burnham, anything over 100ppm chlorides will require shutting the boiler off, letting it settle so your solids drop to the bottom and then perform bottom blowdowns to remove these solids, which are the results of your chlorides test.


Oxygen scavenger, continously injected to maintain a reserve within the boiler of 0.02 to 0.1 ppm and a feed water O 2 content of less than 10 ppb; At temperatures greater than 350 o C , will decompose to ammonia and nitrogen and will aid in maintaining balanced alkalinity in steam piping.Steam volatile, neutralises CO 2
