The Effects of Carryover in Steam Boiler Systems

In some plants, dissolved solids level is the primary factor controlling whether carryover occurs while in others it is alkalinity level. Oil, grease, or other organic contaminants can also cause carryover due to foaming. The alkalinity in boiler water can react with these contaminants to produce a crude soap that causes foaming and carryover.

Cooling Water and Boiler Feed Water – Hach

Cooling water. Cooling water is used in industrial processes to dissipate large amounts of heat. Boiler feed water, on the other hand, is used in the water/steam circuit for electricity generation in power stations. The water has to meet specific requirements for both applications, which is

Boiler Water Treatment - SlideShare

• Chemicals are added to the boiler water. • React with dissolved salts to convert them into less harmful sludge which can stay in the boiler water without creating any harm to the boiler tube. • Later sludge can be removed from the water boiler. 15. Soda Ash (Sodium Carbonate) Treatment • Na₂CO₃, Treatment is done in small boilers.

How Boiler Feedwater Quality Can Affect Boiler

They can perform a number of tests on the feedwater, boiler water and condensate to confirm a carry-over situation. In some cases, the boiler will need to be brought offline and cleaned by a qualified service company to remove the oil, grease or other product contamination. In other cases, the foaming can be addressed with a simple water additive.
