Feedwater Deaerators | Oxymiser | Hurst Boiler

This steam is induced through a stainless steel spray valve assembly which causes the high velocity steam to break the water down to a fine mist through a violent scrubbing action. The deaerated water spills over to the tanks storage compartment for use by the boiler, and the gases are vented to the atmosphere. Standard Equipment

A variation of the spray type is the spray-scrubber type. Deaerator. All medium to large steam systems require a deaerator to reduce the levels of dissolved oxygen (O 2) and carbon dioxide (CO 2) in the boiler feedwater, both of which will cause corrosion to boiler system components if not removed.

5 Deaerator Problems and Corrective Actions |

In order to accelerate this process, deaerators use either a tray type or spray type feed system that drastically increases the surface area of the water and allows the steam that is injected into the deaerator to heat the water more rapidly. A proper operating deaerator should be able to get the total concentration of oxygen down to 5 ppb.
