Meaning Of Carryover In Steam Boiler

Pages - Controlling TDS in the Boiler Water

Controlling TDS in the Boiler Water As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As the dissolved solids become more and more concentrated, the steam bubbles tend to become more stable, failing to burst as they reach the water surface of the boiler.

      • Boiler Carryover - Industrial steam

        industrialsteam.com/boiler-carryover

        In nearly every instance, we have found excessive boiler carryover to be the culprit. In other words, boiler water is leaving with the steam which results in water requirements exceeding pump capacity. Low pressure boilers are primary offenders although high pressure units are sometimes responsible. Carryover can be either mechanical or chemical.

      • What is Foaming? - Definition from Corrosionpedia

        Foaming has a negative impact on industrial operations. For example, boiler water carryover is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This foaming is caused by high concentration of any solid in the boiler water.
