  • 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

  • The Importance of Boiler Water and Steam Chemistry

    High boiler water alkalinity increases the potential for foaming, particularly in the presence of suspended matter. Where a chemical species is sufficiently volatile, it also carries over as a vapor in the steam. Total carryover is the sum of the mechanical and vaporous carryover. Vaporous carryover depends on solubility in steam and is
