      Boiler Chemicals - Oxygen, Scale, and pH Adjustments

      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.

      Jun 26, 2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3 ) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.

      Both of these conditions can be caused by a high water level in the boiler. Priming and carryover can also be caused by a high concentration of chemicals in the boiler water, impurities in the boiler water that cause a high surface tension (such as oil), and/or opening a main steam stop valve too quickly.

      Chemical Water Treatment - an overview | ScienceDirect Topics

      Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness. Second, we add chemicals to the feedwater to adjust the pH, create less favorable conditions for deposition, and remove oxygen. Special water treatment chemicals are used in almost all boilers.

      Chemical deaeration is done through the introduction of specific chemicals in the boiler to react with the oxygen. The dissolved oxygen content should be maintained at a minimum but at no time should it exceed 0.007 mg/l. Sulfites. Sodium sulfite is generally used for the chemical removal of dissolved oxygen within the boiler water.

      Aug 08, 2013 · The chemical boiler treatment of boilers used in the food and beverage industry is for the most part similar to the treatment demands of any industrial boiler. The chemical treatment program should address the basic needs of corrosion and scale control in the boiler, along with minimizing carryover of boiler water into steam.
