Water Handbook - Steam Purity | SUEZ

Steam purity should not be confused with steam quality. Steam quality is a measure of the amount of moisture in the steam. It is expressed as the weight of dry steam in a mixture of steam and water droplets. For example, steam of 99% quality contains 1% liquid water. Carryover is any solid, liquid, or vaporous contaminant that leaves a boiler

What is Carryover | Causes of Carryover

When any solid, liquid or vaporous contaminant leaves the boiler drum along with the steam, the phenomenon is called as carryover. Carryover though does not sound like a serious issue, can affect performance of a steam system in many ways. Carryover results from incomplete separation of water from mixture of steam and water.

The Importance of Boiler Water and Steam Chemistry

Hence, if vaporous carryover for a species is excessive, the carryover can only be reduced by altering the boiler water chemistry. Only mechanical carryover is affected by boiler design. Noninteractive gases such as nitrogen, argon and oxygen carry over almost entirely with the steam, having no relationship to moisture carryover.

Carryover with steam - Wikipedia

Carryover with steam, in steam technology, refers to transport of moisture and impurities with steam. The moisture carryover with steam is quantified by the mass flow rate of liquid water per mass flow rate of steam. In boilers producing saturated steam, it is typically about 0.1% but may increase with fouling and boiler impurities.
