TMBRYAN STEAMSeparable Tank Tray Type Boiler Feedwater DeaeratorsCapacities 70,000 to 300,000 PPH (2030 to 8695 BHP)Form No. 6440(5/00)Performance Features• Oxygen removal to .005 cc/l (7 PPB)• CO2 removal to 0% measurable• Reduce chemical costs• Reduce boiler and system corrosion• Pre-heat boiler feedwater• Improve boiler efficiency• Quick equipment payback, comparedto chemical oxygen removalConstruction Features• Constructed to ASME Section VIII,Division I for 50 PSIG• Hinged tray access door• Standard 10 minutes deaerated water storage• Easily accessible manway in storage tank• All internal surfaces that contactundeaerated water are constructed of type304L stainless steel• Internal direct contact vent condenserfor minimum steam loss• Structural steel stand/pump platform• 2-stage deaeration• Available as completely packaged unitincluding pumps and control panelThe Bryan tray type deaerator is unsurpassed inperformance and reliability. These units areASME Code pressurized units, and are guaran-teed to deliver deaerated water at a maximumoxygen content of .005cc/l (7PPB) and zeromeasurable CO2. All internal surfaces thatcome in contact with undeaerated water areconstructed of type 304L stainless steel for longlife and low maintenance. Their long residencetime makes them readily adaptable to allsystems, even where wide load swings occur.A complete line of boiler feedpump andcontrol packages is available making the Bryantray deaerator a completely packaged unitready for installation with the minimum amountof field assembly.175,000 PPHunit shownNon-Condensable Gases (O , Co )2 2Deaerated WaterSteamTrayAccessDoorDeaerator Outletto Storage TankStainless Steel Vent PipeVented to AtmosphereStainless SteelInternal Vent CondenserStainless SteelSpray TubeWelded StainlessSteel TraysStainless SteelTray ChamberCondensate Returnand Water Make-up©2000 Bryan Steam LLC 50-2517ATMBryan Steam LLC — Leaders Since 1916783 N.
