Industrial‑Grade Deaerator Tank for Chemical Boiler Systems
Our deaerator tank for industrial chemical boiler system is engineered to remove dissolved gases—primarily oxygen and carbon dioxide—from feedwater before it enters the boiler. By delivering consistently low‑oxygen water, the tank protects heat‑exchange surfaces, extends equipment life, and reduces corrosion‑related downtime in high‑temperature chemical processing plants.
How It Works
The deaerator operates on a two‑stage principle: thermal stripping and mechanical venting. Feedwater is pre‑heated by steam injection, which reduces gas solubility. A venturi‑type spray nozzle atomizes the water, maximizing surface area for gas release. The liberated gases are captured by a steam‑driven vent condenser and safely expelled to the boiler house vent stack. Continuous circulation ensures that water exiting the tank meets the stringent dissolved‑oxygen limits (<0.02 mg/L) required for aggressive chemical environments.

Application Scenarios
- Large‑scale petrochemical refineries where feedwater quality directly impacts catalyst longevity.
- Pharmaceutical manufacturing plants that operate high‑pressure steam boilers for sterilization.
- Food‑grade chemical processing facilities requiring strict corrosion control to meet hygiene standards.
- Power generation units that integrate waste‑heat recovery boilers with aggressive condensate chemistry.
Selecting the right deaerator tank for industrial chemical boiler system ensures compliance with plant‑wide water‑treatment protocols and helps achieve the desired boiler efficiency of 90 %+ even under fluctuating load conditions.
Industry Certifications & Safety
Our tanks are manufactured in facilities audited to ISO 9001 and ISO 14001 standards. All pressure‑vessel components comply with ASME Section VIII, Division 1, and are CE‑marked for the European market. For chemically aggressive service, we offer options that meet API 650 and PED (Pressure Equipment Directive) requirements.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑size deaerator?
We accept orders as low as a single unit for prototype or pilot‑plant projects. Larger volumes benefit from volume pricing and reduced lead time.
Can the tank be fabricated from materials other than stainless steel?
Yes. In addition to AISI 304/316L, we offer duplex, super‑austenitic, and carbon‑steel options with internally applied corrosion‑resistant linings to match specific chemical environments.
What warranty and after‑sales support are provided?
All units carry a 24‑month warranty covering material defects and workmanship. Our technical service team offers on‑site commissioning, performance testing, and spare‑part logistics worldwide.
How long does delivery typically take?
Standard production runs are shipped within 15–45 days after receipt of a confirmed purchase order. Expedited schedules are possible with advance notice and additional tooling fees.
