Cochrane Spray Atomizing Deaerator
The COCHRANE® Atomizing Deaerator is a two-stage
design.
In the first stage, water is sprayed in direct contact with steam and heated practically to saturation temperature. At this stage the bulk of the non-condensible gases are liberated and all released gases are discharged from the unit.
The preheated, partially deaerated water then passes to the second stage where it comes in contact with a constant high velocity steam jet for final deaeration.
The steam jet is created by a variable orifice atomizing
valve which is self-compensating to changes in load or variation in operating conditions. The energy of the steam jet breaks up the water, producing a mist or fog of finely divided particles to assure maximum surface exposure to the scrubbing steam. Any remaining gas is removed and carried to the first stage by the steam, while the deaerated water falls to the storage section.
