De-aerator for boiler feed water
Bono ARTES

Dissolved gases such as oxygen and carbon dioxide must be reduced in Boiler Feed Water in order to prevent boilers and steam circuits from corrosion. The thermo-physical deaeration process is by far the most applied technology when a reduction of oxygen to only a few parts per billion is required. While part of the BONO Group, ARTES Ingegneria is in the business of Deaerators since 1958.
The degassing process is achieved in the deaerating tower where make-up water is atomised on a set of special packing that increases the contact surface between water and steam. Oxygen and carbon dioxide are stripped by the steam flow and vented through a calibrated orifice. Deaerated water is collected in the storage tank so as to assure an adequate “Hold-up” time for the boiler downstream.
According to the design capacity and steam flow, the deaerating tower may be arranged on a vertical or horizontal geometry so that, in the latter case, a larger surface of mass and heat transfer is implemented.
Deaerators are manufactured and marketed on BONO Artes’ own proprietary design in order to assure the complete responsibility of the concerned unit.
