Boiler Chemistry Control and Treatment of Feed Water

May 05, 2015 · 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. N 2 H 4 is used to scavenge Dissolved Oxygen and protect Copper alloys from Ammonia.
