Test for Sodium Sulfite - tpub.c

Test for Sodium Sulfite . The sample for this test should be cooled to 70F, or below, and exposed to the air as little as possible, because oxygen in the air combines with sodium sulfite in the sample and causes low readings. Collect a separate sample, using the boiler water sample cooler, with the line reading to the bottom of the sampling bottle.

Generally it is desirable to have a slightly high pH for boiler feed water. Ideally the feed water should be in the range of pH 8.5 – 9.5. This ensures that free carbon dioxide within the system becomes ‘fixed’. If copper fed lines or heaters are used, restrict the feed water pH to a maximum of 9.2.

May 04, 2016· Sulfite Test. Sulfite is added to boilers to remove dissolved oxygen, which causes severe pitting corrosion. Theoretically, it takes about 8 ppm of sodium sulfite to react with 1 ppm of oxygen. To assure that this reaction goes to completion and that all oxygen is removed, an excess of 30 to 70 ppm of sulfite should be carried in the boiler water.
