Abstract

The demineralized water that is used in boilers for steam production has to meet stringent water quality demands, because of the steam-water cycle’s susceptibility to corrosion (1). Of special concern are the areas where flashing occurs, or the first droplets of condensate are formed. Water droplets in areas with high steam voidage contain the majority of (in)organic anionic impurities introduced by the feedwater and potentially return condensate.
