Flue gas scrubbers

Optimize Flue Gas Scrubber Performance

Flue gas scrubbers face significant wear due to corrosive environments and mechanical stress. Selecting the right stainless steel grade can extend equipment life and reduce maintenance costs.

The service challenge

The primary wear mechanism in flue gas scrubbers is corrosion combined with sliding abrasion, leading to the degradation of components like linings and nozzles. Typically, the most vulnerable parts are those exposed to both chemical reactions and mechanical abrasion.

Recommended product by component

Component	Grade	Thickness	Why
Scrubber Lining	S31603	5-10 mm	Enhanced resistance to corrosive media yields longer service life.
Inlet Baffle	S904L	4-8 mm	Superior pitting resistance suitable for harsh flue gas conditions.
Outlet Duct	S32205	6-12 mm	Robust mechanical properties provide durability against wear.
Spray Nozzle	S31008	3-5 mm	High-temperature tolerance with good oxidation resistance ensures reliability.
Demister Pad	S34700	2-4 mm	Corrosion-resistant, maintaining performance in wet environments.

Selecting the right product

Choose corrosion-resistant grades

Grade selection should prioritize resistance to both oxidation and pitting.

Consider thickness requirements

Thicker plates offer enhanced durability but may require increased weight support.

Assess environmental factors

Understand the chemical composition of flue gas to tailor material choices effectively.

Evaluate mechanical stresses

Components exposed to high mechanical loads should utilize high-strength stainless steel grades.

Questions engineers ask

What is the best grade for high corrosion resistance?

S904L is recognized for its exceptional resistance to pitting and crevice corrosion in aggressive environments.

How does thickness impact performance?

Increased thickness can improve durability but may also influence installation and operational dynamics.

Can I use a ferritic grade?

Ferritic grades may not provide sufficient corrosion resistance for flue gas applications; austenitic and duplex grades are recommended.

What approvals do your materials have?

All products come with an EN 10204 3.1 mill test certificate, ensuring traceability and compliance with industry standards.
