Types Of Deaerators

Spray type Deaerator System

Spray type deaerator is a cylindrical vessel used for the removal of dissolved gases from the feed water. Basically, the removal of dissolved gases is done by either decreasing the pressure or increasing the temperature inside the deaerator. The feed water fed into the deaerator will pass on through the vented section where the water will experience high steam which allows the feed water to remove dissolved gases. The spray type deaerator diagram is shown below.

Tray type Deaerator System

Tray type deaerator utilizes a vertical dome placed on the horizontal section of the vessel. The basic difference between a tray-type and spray type is in tray-type both a spray nozzle and trays are used.

By using both spray and trays, the mixing of air and water provides better heat exchange, and the dissolved gases present in the feed water are eliminated more efficiently. The diagram of this deaerator is illustrated below.

and equipment for a complete non-destructive examination of vessels within your facility.
