Explained: How Does a Deaerator Work? - Boiler

2019-9-13 · Why steam is used as a purge gas in deaerator? It doesn't contaminate the water. Only a small quantity of steam is venting from deaerator. Most of the steam condenses and becomes the part of deaerated water. It heats the boiler feed water up to the saturation temperature so that solubility of unwanted dissolved gases are decreases.
