Degassing Boiler Feed Water in China with 3M Liqui-Cel

Water and steam that is purged from the boiler during blow down is sent to drain. This water must be replenished by fresh makeup water and there is a cost associated with it. The second cost is heat or energy cost. The water blow down from the boiler is hot. It is replaced with cold water that must be reheated in order to produce steam.

Application Note: Monitoring Steam Purity in Power Plants

Plants with drum-type steam generators both conventional boilers and heat recovery steam generators (HRSGs) maintain steam purity by taking advantage of the physical separation that occurs between water and steam in the drum. As the water boils, it forms a steam-water mixture, which upon entering the drum separates into steam and water.

Cation Conductivity & Its Importance- Water Treatment Basics

Oct 20, 2018· Degassed Cation Conductivity: The degassed cation conductivity measurement uses the same ion exchange strategy as the cation conductivity measurement. The degassed measurement incorporates a reboiler to remove volatile compounds (like ammonia, amine, volatile organics, and CO 2) from the steam to provide a more accurate indication of sulfate and chloride levels.

Evaluation of Degassed After-Cation-Exchange Conductivity

ical calculations for ACC and degassed ACC. INTRODUCTION Feedwater, boiler water and steam in generating plant should contain as little as possible of any ionic species known to initiate or enhance corrosion, such as chloride, sulphate, acetate and formate. To ameliorate the effects of any traces of these ions alkalising agents are added to
