What is Atmospheric Deaerator?
An Atmospheric Deaerator removes dissolved oxygen and other non condensable gases from feedwater before it enters a boiler. Water is sprayed or cascaded through a steam filled dome, heating it to near saturation temperature. This process reduces oxygen levels to acceptable limits, preventing corrosion in boiler systems, piping, and other downstream equipment. The liberated gases vent to the atmosphere, hence "atmospheric." Its primary function is to protect industrial boilers and steam plants from oxygen pitting and extend equipment lifespan by minimizing scale and corrosion, crucial for efficient and safe operation.
