One of the measures of safe operation steam-boiler systems is purity pipes. Very acceptable method of determining the soiling pipe is a method of staining.In this paper is described the determination of soiling boiler tubes in power plant Ugljevik after a decade of operation of the plant

Steam System Survey Guide - Energy

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
