FEATURES
COUNTER FLOW TRAY design provides guaranteedremoval of all dissolved oxygen in excess of .005 cc/literfrom 5% to 100% of deaerator capacity.
ELECTRONIC INSTRUMENTATION FORMODULATING LEVELcontrol includes a HART compatible differential pressure transmitter, PID controller, and motorized control valve.
MULTIPLE CONFIGURATIONS: vertical single tank, standard“tank car” type, or flanged heater section, all providing the samehigh quality deaeration.
ONLY STAINLESS STEEL components come in contact withundeaerated water. Trays and tray box are all stainless steel.
A.S.M.E. Code and National Board stamped receivers at 50 psi is standard. Standard vessel options include stress relieving, non-destructive testingand full vacuum.
CUSTOM ENGINEERED PACKAGED SYSTEMincludes boiler feedwater pumps and quality components to insurereliable service.
Testing RequirementsThis system requires steady state conditions per the ABMAtesting procedure.

ADVANTAGESCounter Flow Tray type deaerators are capable of accepting high percentages of condensate returns without adverse effects on performance. This is possible because the deaeration process does not require a flow of steam for scrubbing. All second stage scrubbing is doneby the cascading process through the trays. The counter flow design provides maximum performance because the cleanest incoming steam contacts the water that requires final deaeration, thus stripping out the last traces of oxygen. GUARANTEED PERFORMANCE from 5% to 100% of load standard sizes ranging from 6,900 lbs/hr to 300,000 lbs/hr (up to 1,000,000 #/hr upon request) CUSTOM ENGINEERED PACKAGED SYSTEM results in a small foot print, minimal onsite installation costs, and a single source of responsibility for all major components.
OPERATIONMakeup water and pumped returns are sprayed into the tray section through a stainless steel spray nozzle. The spray nozzle provides a thin conical sheet of water that condenses the vapors while permitting oxygen to exit through the vent. The partially deaerated water then begins to cascade through the trays.
The combined makeup and pumped returns are heated with steam that flows upward through the stainless steel trays. The steam vigorously scrubs the dissolved oxygen from the makeup and pumped returns. The trapped returns enter the storage section. Steam from the returns also flows upward through the trays, while the water drops to the water level in the storage section.
The fully deaerated water remains in the storage section for use by the boiler, while theexcess steam flows into the tray section. Non-condensable gases enter the vent and passto the atmosphere.
