Description
Design Advantages:
- Removal of corrosive oxygen and carbon dioxide from boiler feedwater
- Reduction in the use of oxygen scavengers and other 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 to .005 cc/liter (7ppb)
- Guaranteed to eliminate titratable free carbon dioxide to 0
- Guaranteed to heat water to the corresponding temperature of the saturated steam contained within the vessel
