Spray Tray Deaerators and Spray Scrubber Deaerators assist with reducing oxygen
(and carbon dioxide) levels in boiler feedwater.  Typically they are manufactured
as carbon steel pressure vessel with stainless steel internals (trays or packing, spray nozzles,
vent condenser, and tray enclosure).  Deaerator external accessories typically include pumps,
valves, piping, safety valve, vent valve, vacuum breaker, overflow valve, pressure gauge,
thermometer, chemical quill, anodes, strainer, level control, pressure control, flow control,
temperature control, oxygen analyzer, PRVs, blowdown & flash tank, exhaust head,
sample cooler, pre-treatment (such as softener), and other components.

These units can be referred to as Thermal (Steam) Deaerators as well.  In the future more
information on Gas Stripping Deaerators and Vacuum Stripping Deaerators will be included.


A proper Chemical feed system is a valuable component for improving the system.


Post Weld Heat Treatment, Corrosion Allowance, and the amount of Non Destructive Testing
(XRAY, Dye Penetration, Ultrasonic, etc.) are dependant on ASME Code requirements or the
Customer’s specific requirements.  HEI has recommendations as well.


Sizing deaerator units require information on the flows, temperatures, and pressure ratings of the
makeup water, condensate, and steam sources.
