Deaerator Design and Operation - Chem-Aqua, In

Function A deaerator preheats boiler feedwater and removes dissolved gases, especially oxygen and carbon dioxide. These gases are undesirable because they cause corrosion and increase treatment chemical requirements. Operation Deaerators operate based on the reduced solubility of dissolved gases as temperature increases. For example, the solubility of oxygen decreases from about five ppm at ...

Deaerator - Working Principle, Types & Applicatio

Functions of Deaerator One of the properties of water is its surface tension, as it contains a high degree of surface tension which holds all the things together. The application of a surfactant can reduce the surface tension of water. Aeration is the process that breaks the surface tension of the water.
