Boiler ph control
Webboiler in a steam power plant. A pH sensor that works fine in a low-pressure boiler has generally failed in a high-pressure boiler. Choosing a sensor to measure the pH of high-conductivity boiler water is fairly straightforward. As long as the conductivity is greater than 50 µS/cm at 25 °C and the suspended solids concentration is low, the ... WebMay 5, 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.
