There are two main groups of Chemicals for Boilers to choose from. One chemical group for boilers is for steam boilers and the second is for hot water boilers. Steam Boiler Chemicals - These include Oxygen Scavengers, Amines, Phosphates, Polymers, and Alkalinity Builders. Oxygen Scavengers - Most common type is 38%, pH < 4.

May 04, 2016 · 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.

Sep 26, 2016 · After the softening process, some boiler feed water treatment systems will utilize dealkalization to reduce alkalinity/pH, an impurity in boiler feed water that can cause foaming, corrosion, and embrittlement. Sodium chloride dealkalization uses a strong anion exchange resin to replace bicarbonate, sulfate, and nitrate for chloride anions.

During cleaning, boilers are fired at a low rate, but not enough to establish positive circulation. Boil-out pressure is usually about half the operating pressure. Several times during the alkaline boil-out, half of the boiler water should be blown down as shown on the gauge glass through the bottom blowdown valves.
