What is a critical aspect of deareator function?

A critical aspect of a deaerator's function is removing dissolved gases from the feed water. Deaerators are designed to eliminate oxygen and other gases, such as carbon dioxide, from the water before it enters the boiler. The presence of these dissolved gases can lead to corrosion within the boiler system. By effectively removing them, the deaerator helps enhance the longevity and efficiency of the boiler's operation. This process is crucial because protecting equipment from corrosion helps maintain safety and performance standards in steam systems.

While cooling feed water temperature, heating condensate, and storing excess water may be aspects of a steam system, they do not directly relate to the primary role of a deaerator, which is centered squarely on the removal of harmful gases from the feed water.
