Application Scenarios
Power plants, cement factories, and large‑scale process facilities that rely on coal‑fired boiler systems demand reliable oxygen removal to protect turbine blades, economizers, and heat exchangers. Our deaerator tank for industrial coal boiler system is engineered to operate continuously under high‑temperature steam cycles, ensuring the feedwater remains free of dissolved gases even during peak loads and rapid start‑ups. Whether you are retrofitting an aging plant or commissioning a new coal‑based generation unit, the tank integrates seamlessly with existing water‑treatment loops, providing consistent performance across harsh operating conditions.
Product Overview
The deaerator tank for industrial coal boiler system combines a vented storage vessel with a high‑efficiency spray‑type heat exchanger. Water enters the tank at ambient temperature, is heated by steam injection, and circulates through fine nozzles that maximize surface area for gas release. The design eliminates dissolved oxygen, carbon dioxide, and nitrogen, preventing corrosion and scaling in downstream boiler components. Constructed from low‑temperature carbon steel with a corrosion‑resistant lining, the unit meets the rigorous demands of continuous 24/7 operation while offering easy access for inspection and maintenance.

Competitive Advantages
- High‑Efficiency Gas Removal: Dual‑stage venting and optimized spray geometry achieve sub‑ppm oxygen levels without excessive steam consumption.
- Robust Construction: The combination of low‑temperature carbon steel and EPDM inner lining resists both mechanical stress and chemical attack from alkaline water.
- Modular Design: Standardized panels allow on‑site expansion or re‑configuration to match evolving plant capacities.
- Ease of Integration: Pre‑fabricated inlet/outlet manifolds conform to ANSI/ASME B31.1 piping standards, reducing engineering lead time.
- Global Compliance: The unit meets ISO 9001 quality management requirements and is compliant with major international pressure‑vessel codes.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a customized deaerator tank?
We typically accept orders starting at a single unit, provided the required specifications are within our standard design envelope. For highly specialized dimensions or materials, the MOQ may be adjusted to cover tooling costs.
Can the tank be adapted for different boiler capacities?
Absolutely. Our engineering team can scale the water capacity, vent size, and spray nozzle arrangement to match boiler outputs ranging from 30 MW up to 500 MW. Each configuration is validated through CFD simulations and prototype testing.
What is the typical lead time from order confirmation to shipment?
Standard models ship within 15‑30 days after receipt of a purchase order and engineering sign‑off. Customized builds generally require 30‑45 days, depending on the complexity of the modifications.
Do you offer warranty or after‑sales support?
All units come with a 12‑month warranty covering material defects and workmanship. Our technical support team is available 24/7 for troubleshooting, and we provide on‑site commissioning assistance for large projects.
