Precision Boilers – Spray Deaerator

Spray Deaeration Capacity: 5,000 PPH to 300,000 PPH
Storage Capacity: 140 nominal gallons to 6,000 nominal gallons of feed water to overflow



Design Advantages:

  • Removal of corrosive oxygen and carbon dioxide from boiler feedwater
  • Reduction in the use of oxygen scavengers another additives
  • Opportunity to reclaim heat by recovering exhaust and flash steam
  • Improved heat transfer by eliminating non-condensable gases
  • Reduction of thermal shock to the boiler by feeding water closer to the boiler operating temperature
  • Guaranteed oxygen removal in excess of 0.005cc/liter
  • Guaranteed to eliminate titratable free carbon dioxide to 0
  • Guaranteed to heat water to corresponding temperature of the saturated steam contained within the vessel
  • Guaranteed to deaerate at all loads from 3% to 100% of rated capacity
  • Capacities from 5,000 PPH to 300,000 PPH
  • All stainless steel internal vent condenser
  • All stainless steel spray valve(s)
