This 320,000 PPH Boiler Deaerator (DA) Tank is a heavy-duty industrial feedwater deaeration vessel designed to support high-capacity steam boiler systems. Manufactured in 1998 by Alps Welding Ltd., this horizontal boiler room DA tank measures 35 feet in length x 10 feet in diameter and is built for reliable operation in large industrial steam plants.
The unit carries a Maximum Allowable Working Pressure (MAWP) of 50 PSI at 300°F, making it suitable for medium-pressure boiler feedwater applications where oxygen removal, condensate conditioning, and feedwater temperature control are critical to system longevity and efficiency.
What Is a Boiler DA Tank?
A boiler deaerator (DA) tank is a critical component of any industrial steam generation system. It removes dissolved oxygen and non-condensable gases from boiler feedwater before it enters the boiler. Proper deaeration helps prevent:
- Oxygen pitting and corrosion
- Tube failure
- Reduced boiler efficiency
- Premature pressure vessel damage
- Maintenance downtime
For high-capacity operations rated at 320,000 pounds per hour (PPH) steam production, a properly sized DA tank ensures stable feedwater conditions and supports continuous boiler performance.

Why Deaeration Is Critical in High-Pressure Boiler Systems
In large-scale steam plants, dissolved oxygen as low as a few parts per billion can cause severe corrosion in boiler tubes and piping. A properly engineered DA tank:
- Heats feedwater close to saturation temperature
- Releases dissolved oxygen through steam scrubbing
- Protects downstream boiler pressure vessels
- Improves overall steam plant efficiency
- Extends equipment life cycle
For facilities operating at or near 320K PPH steam output, deaerator reliability directly impacts operational stability and plant uptime.
Typical Industrial Applications
Industrial buyers searching for a used boiler DA tank for sale, surplus deaerator vessel, or industrial boiler feedwater tank 50 PSI will find this unit suitable for plant upgrades, capacity expansions, or replacement projects.
Benefits of Purchasing a Used Industrial DA Tank
Acquiring surplus pressure vessels can provide:
- Lower capital investment vs. new fabrication
