Oxygen Scavengers - SUBSPORT

The oxygen scavengers used in the higher pressure boilers, and the ones with which diethylhydroxylamine (DEHA) com-petes most directly are hydrazine and catalyzed hydrazine. Hydrazine does not produce corrosive gases at high tem-peratures and pressures, and in application, reacts with oxygen to form nitrogen and water: N 2H 4 + O 2 2 H 2O + N 2

As a knock on effect will slightly increase boiler water alkalinity. Stable at high temperatures so is used more than hydrazine to control the steam line alkalinity as there is less chance of copper corrosion which occurs with the prescience of ammonia. Proper boiler water treatment eliminates sludge and scale deposits within the boiler.

with chemical treatment, using oxygen scavengers such as hydrazine, DEHA and carbohydrazide to consume remaining DO. Theoretically, maintaining a high residual of an oxygen scavenger would consume all dissolved oxygen. In reality, competing chemical reactions between oxygen and boiler surfaces are more likely to occur, resulting in
