Spray Type Deaerators More Economical Than Trays

Spray type deaerators provide its users with economic alternatives. These units list features such as simplified, hassle free and quietish designs designed to manage ongoing carrying and processing loads. The rest of this short informational article reveals how the spray type deaerator operates.

All incoming un-deaerated water enters the spray type deaerator through its spring loaded stainless steel spray valves. These orifice valves then produce a fine spray in uniform patterns, varying from 5 percent to 200 percent of its design. Fine droplets of water will maximize surface areas placed in contact with steam.

Temperatures are raised to within a few degrees of saturation temperature. This will result in the instant release of a majority of corrosive and non-condensable gases. Preheated and partially deaerated water then gets channeled through a collection basin down-comer. It is a tortuous path towards a second stage deoxygenator.

Here the hottest and purest steam scrubs water vigorously in order to heat it to its saturation temperature and strip out the remaining vestiges of dissolved gases. Steam and all other non-condensables flow upwards towards the stainless steel vent’s condensing area. This is where the steam is condensed with its inlet water.

Gases are released to the atmosphere through the vent outlet. All deaerated water then drops down into a storage area. Firm features of the standard spray type deaerator include the following. The unit merely occupies a small footprint or plan area. Overall, the system is of low cost to maintain and operate.  

Oxygen removal capacity comes in at 0.005 cc per liter per HEI. The units have the ability to manage volume capacities ranging from 260,000 units per hour to as much as 800,000 units per hour. In accordance with the smooth running of every industrial business, customers are encouraged to go in for custom prepared deaerators.
