Rotary Film Deaerator for Boiler Metallurgy
Rotary Film Deaerator for Boiler Metallurgy is one of our core products. From single replacement units to full power-plant retrofits, every rotary film deaerator for boiler metallurgy is designed, welded, assembled and pressure-tested in our own works in Lianyungang.
- ✓ Quotation in 12 working hours
- ✓ MOQ from 1 pc
- ✓ DDP door-to-door
Rotary Film Deaerator for Boiler Metallurgy engineered and fabricated in-house
Because design, cutting, welding, machining and assembly all happen in our Lianyungang works, rotary film deaerator for boiler metallurgy orders move from drawing approval to factory acceptance test without third-party handoffs — the stage where most delivery delays and leakage problems start.
What we deliver
- Spray-tray or rotary-film internals engineered for stable oxygen removal across load swings
- Sponge-iron media vessels with long-life filter material and simple replacement
- Horizontal or vertical arrangement matched to the boiler house layout
- Complete skid: vessel, internals, level control, safety valve and instrumentation
- Factory acceptance test with leakage, torque and sealing-air reports for every unit

Metallurgy applications
In metallurgy duty the rotary film deaerator for boiler metallurgy works continuous thermal deoxygenation of feedwater. We size the shaft, bearings and actuator for the actual dust load and temperature of the duct, not just the nominal cross-section, because a gate that jams during a shutdown trip costs far more than the difference in purchase price. Critical welds are inspected 100% on the first unit and by sampling (AQL 1.0) afterwards.
How the project runs

FAQ
Questions about Rotary Film Deaerator for Boiler Metallurgy
What is the price of rotary film deaerator for boiler metallurgy?
Pricing depends on size, material and sealing class. Send us the duct dimensions, design temperature and pressure, and we will return a detailed quotation with material and fabrication cost breakdown within 24 hours. Replacement units for existing installations can be dimensioned from site drawings or photos.
What is the lead time for rotary film deaerator for boiler metallurgy?
Standard sizes ship in 20–30 working days after drawing approval; custom-engineered units typically need 25–35 days including internals fabrication. Worldwide export packing and shipping are available.
Can you match our existing installation?
Yes. Most of our output is retrofit work: we dimension flue gas dampers, slide gates and silencers from site drawings, templates or measured flange positions, and supply mating flanges, expansion joints and sealing-air systems to match.
Do you support metallurgy projects?
Yes. We supply metallurgy operators with rotary film deaerator for boiler metallurgy units tested for leakage, actuator torque and sealing-air pressure, complete with commissioning support and spare sealing parts. Our qualifications cover Sinopec, PetroChina, China Guodian, China Datang, CNOOC and Chalco supplier systems.
