Low-Pressure Boiler Makeup Water Treatment: Part 1

Dec 04, 2019 · Figure 1. Calcium carbonate scale on the internal surface of an extracted heat exchanger tube section. For decades, a typical primary treatment method for industrial boiler makeup was sodium zeolite softening. In this process, the water passes through beds of ion exchange resin, where the hardness ions calcium and magnesium are swapped for sodium.

BASIC WATER TREATMENT OF STEAM BOILERS

May 02, 2000 · Similarly, if better dissolved solids control is required, another form of ion exchange may be employed. Demineralization is a method of choice for removal of nearly all dissolved solids for higher-pressure boilers that have tighter restrictions on boiler chemistry. Positively charged ions (cations) such as sodium, calcium, magnesium, and

The Effects of Corrosion in a Boiler | Chardon Labs

Sodium carbonate can convert into sodium hydroxide through hydrolysis. The latter compound reacts with iron in the boiler, dissolving it and producing sodium ferrate. This product then undergoes hydrolysis again, converting back to sodium hydroxide, continuing the process.

Water Handbook -Boiler Deposits: Occurrence And Control | SUEZ

Sodium carbonate treatment was used to precipitate calcium as calcium carbonate to prevent the formation of calcium sulfate. The driving force for the formation of calcium carbonate was the maintenance of a high concentration of carbonate ion in the boiler water. Even where this was accomplished, major scaling by calcium carbonate was common.

Ion exchange An ion exchanger is an insoluble material normally made in the form of resin beads of 0.5 to 1.0 mm diameter. The resin beads are usually employed in the form of a packed bed contained in a glass reinforced plastic pressure vessel. The resin beads are porous and hydrophilic - that is, they absorb water.
