function of deaerator in boiler

function of deaerator in boiler - insm

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.

What is the main function of Deaerator tank? -

A deaerator is a device that is widely used for the removal of oxygen and other dissolved gases from the feedwater to steam-generating boiler. In particular, dissolved oxygen in boiler feedwaters will cause serious corrosion damage in steam systems by attaching to the walls of metal piping and other metallic equipment and forming oxides (rust).

4 Things to Know for Increasing Steam Boiler

A deaerator is a specifically designed piece of equipment to condition make-up water before it can be used as boiler feedwater. The resulting high quality feedwater has far lower concentrations of dissolved oxygen and non-condensable gases leading to minimized operating costs and improved steam quality.
