    May 04, 2016 · The chloride test is used (often in conjunction with the conductivity test) to regulate boiler blowdown. Blowdown is necessary to keep boiler solids (both dissolved and precipitated) from building up to the level where they might cause scale and carryover. Boiler water chlorides limits are set on the ideas that:

    Dec 13, 2019 · In this test barium chloride is added to the boiler water sample to precipitate all the carbonates which are present. The test is then carried out as for the alkalinity to phenolphthalein test but in this case only the hydroxides (caustic) will be measured. BaCl2 + CaCO3 = BaCO3 + CaCl2 Ca (OH)2 (aq)+H2SO4 (aq)—→ CaSO4 (s)+2H2O (l)

    Chloride is normally never tested in BFW. It is tested in DM water, though, where a typical analysis would show nil chlorides (chlorides as CaCO3). Are you hinting at an upset in the DM plant? If there is at all any chloride ingress in the BFW, it could only be removed over a period of time through blow-downs.

      boiler water chloride level should be monitored to ensure the blow down rate is correct. If the chloride level is higher than the recommended maximum, more blow down is needed. If it is low, excess blow down is occurring, resulting in wasted chemicals, water, and heat energy. In some cases the chloride level never approaches the recommended

      Because chlorides do not precipitate in the boiler water, the relative chloride concentrations in feedwater and boiler water provide an accurate basis for calculating the rate of blowdown. The chloride test is unsuitable for this calculation when the feedwater chloride is too low for accurate determination.
