Total Dissolved Solids - TDS - Engineering ToolBox

When a boiler generates steam impurities in the feed water will concentrate in the boiler water. When the concentration of impurities becomes higher, foam is generated and the volume of the boiling water starts to increase. As a result - more and more low quality wet steam will be generated.

Boiler feed water - Water Treatment and Purification

Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler.
