Features and Benefits
Low Profile Design: Low head allows installation in space restricted areas.
Two-Stage Deaeration in a Common Vessel:
Recycle pumps are not required,
packaged for easy maintenance.
ASME Code Design (Section VIII):
Assures deaerator vessel quality in materials and fabrication to meet safety requirements.
Internal Stainless Steel Vent Condenser:
Protects deaerator vessel against corrosive gases while providing a means for removal of corrosive gases from boiler feedwater.
Self-Cleaning Water Spray Valve:
Angles associated with the water spray valve assembly and actual water spray pattern, maintains deposit-free surfaces,
reduces maintenance requirements.
Internal Automatic Check Valves Prevent Back Flooding:
Both the water spray valve and steam atomizing valve are in the normally closed position under no flow conditions,
prevents steam back-flow through the water spray valve and water back-flow through the steam atomizing valve.
Removable Water Spray Inlet Assembly:
Flanged assembly allows easy access for maintenance and/or inspections.
Stainless Steel Deaeration Assembly:
Ensures a longer life of wetted materials in intimate contact with corrosive liquids and released corrosive gases.
Pressurized Tank Reduces Flashing and Minimal Venting:
Recovery of exhaust and turbine steam,
saves Btu's that would normally be exhausted to atmosphere, improves plant efficiency.
Auto Vent Valve Eliminates Dissolved Gases at Start-Up:
Atmospheric contamination virtually eliminated for incoming water.
Exceeds ASME Recommendations for Oxygen Level:
Guaranteed to remove oxygen concentrations to 0.005 cc/liter while operating between 5% and 100% capacity,
carbon dioxide concentrations are practically reduced to zero.
Capacity Not Affected by Mixed Inlet Temperature:
Consistent performance under variable conditions.
Integral Level Control Automatically Introduces Cold Water Make-Up to Supplement Condensate Only When Necessary to Meet Boiler Demand:
Saves Btu's by accepting condensate before cold make-up water, maintains a minimal water level within the deaerator vessel to prevent damage to the boiler feedpumps, and to maintain system operation.
Variety of Tank Sizes to Handle Volume-Swings in Condensate Return:
Provides flexibility for selecting a tank for specific applications, limiting the loss of hot condensate to drain.
Packaged Units for Cost Effective Installation:
Complete packages are pre-fabricated in the manufacturing facility to ensure piping alignment and control wiring function,
the unit is partially disassembled, and match marked for efficient field re-assembly.
Available in Horizontal and Vertical Configuration:
Provides adaptability for installation in space restricted areas.
Internal Pump Suction Vortex Breakers:
Eliminate the problems of loss in NPSHA (Net Positive Suction Head Available) and cavitation associated with the creation of vortices within pump suction piping.
Product Offering
Information in this section applies directly to Cleaver- Brooks packaged Spraymaster Deaerators (single tank) ranging from 7,000 to 280,000 pounds/hour. For duo-tank and larger capacity information contact your local Cleaver-Brooks authorized representative.
The Spraymaster Deaerator is a pressurized low-headroom system designed to remove dissolved oxygen in boiler feedwater to 0.005 cc per liter, or less, and eliminate carbon dioxide. A typical deaerator package includes the deaerator tank mounted on a stand of appropriate height along with all operating controls, feed pumps assembled and piped (typically knocked down for shipment and field assembly). The tank conforms to section VIII of the ASME code.
The main deaerating portion is located internally and consists of a water collector and steam atomizing valve. Built into a flange on top of the tank is a spring loaded water spray nozzle which includes an automatic and manual vent valve. Packaged Spraymaster systems offer substantial advantages through, lower cost installation and simplified operation and maintenance. Spraymaster Deaerators arrive on site ready for hookup to your water, steam, and electric power connections. The deaerator stand comes with feed pump/motor set. The base is specially reinforced to prevent vibration wear on vital system components. Rugged square structural tubing combines lasting strength with generous working space for inspection or routine servicing.
Control Panel
The control panel, complete with starters, fuse protection, switches, lights and pre-wired terminal blocks is mounted on the stand assembly. Wiring to feed pump motor and all controls is standard.
Deaerator Tank
ASME construction - certified to 50 psig. All tanks provided with manhole, individual pump suction tappings and other openings as required. Saddles or legs standard on all sizes. Select from sizes for 5 to 30 minutes of storage to overflow.
Piping
Pump and motor sets are mounted on individual bases before mounting on stand. Individual suction piping (including strainer, shutoff valve, flexible connector) are provided for all feed pumps.
