QUIZ: Boiler Water Treatment Chemical Guidelines — Part II

Chelating agents offer an opportunity for supplying better results in boiler water treatment (i.e., cleaner boilers). The important key to success is to use the same care in selecting, applying, and controlling the treatment program. Chelating programs are another variation of water treatment. The word chelate derives from the Greek word chele,

oxygen scavengers. Oxygen scavengers are reducing agents that react with even the very low levels of oxygen left in water by good deaeration. They are normally added to the storage section of the deaerator, to allow time for reaction before the feedwater reaches the boiler. Low pressure boilers sometimes do not include mechanical deaerators. In
