Corrosion is defined as the destruction of materials over time by the effect of the environment they are in. The type of material where corrosion is most common is metals due to their high tendency to electrochemical reactions. The effect of corrosion of metals is related to the quantity of oxygen present. Metals that are stable in the free state (titanium, etc.) have higher corrosion resistance, while metals with relatively higher oxygen content (iron, etc.) tend to oxidize more easily.

 Free Oxygen (O2) and Carbon Dioxide (CO2) gases dissolved in the steam boiler feed water cause damage to the metal surfaces of the boiler and steam installation. In order to remove these corrosive gases from the composition of the feed water, the latter is broken into small particles and by heating it with steam so that carbon dioxide (CO2) can separate at 60°C and oxygen (O2) at evaporating temperatures above 100°C. In the thermal deaeration system, the separation of the feed water into small particles is done with the sprinkler system.
