Boiler Chemistry Control and Treatment of Feed Water .
May 05, 2015· Two basic ways to regulate corrosion in water, are All Volatile Treatment (AVT) and Oxygenated Treatment (OT). Two types of AVT are; i) AVT (R) Using Ammonia (NH3) and as reducing agent like Hydrazine (N 2 H 4), ii) AVT (O) same as AVT ® minus reducing agent i.e. N 2 H 4. Ammonia is commonly used cheaper material to maintain pH in boiler water.Get a Quote
