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
Read MoreIf the boiler water quality is unqualified, the steam will inevitably contain impurities. Excessive impurities will cause salt accumulation in the steam turbine cocurrent part of the boiler heating surface or steam pipeline. If salt scale deposits, it will reduce heat transfer
