View catalogProblem & Solution
Overcoming Critical Challenges in Flue Gas Treatment
Low Removal Efficiency: Inefficient atomization results in poor gas-liquid contact, making it difficult to meet SO₂ and NOx emission limits.
Severe Nozzle Clogging: Limestone slurries and particulate-laden gas streams frequently block traditional nozzles, leading to costly downtime.
Abrasive & Corrosive Wear: Constant exposure to high temperatures and corrosive chemicals (acids/alkalis) causes rapid nozzle erosion and shortened service life.
Engineered Solutions for Stable, Long-Term Operation
Maximum Contact Area: Our nozzles produce a precise, uniform droplet spectrum (50–500 µm) for optimal scrubbing and absorption efficiency.
Advanced Anti-Clogging Design: Featuring Large Free Passage geometry, our nozzles allow large particles to pass through without interruption, minimizing maintenance.
Superior Material Durability: Constructed from Reaction-Bonded Silicon Carbide (RBSC) and 316L Stainless Steel, ensuring 3-5x longer life in high-wear desulfurization environments.

Materials Designed for Corrosive & High-Temperature Environments
Reaction-Bonded Silicon Carbide (RBSC/SiSiC)
The industry gold standard for FGD absorber spray headers. Offers extreme hardness and resistance to the high-velocity erosion of limestone slurries, extending service life in abrasive desulfurization conditions by over 300%.
Stainless Steel 316L & 310S
A cost-effective solution for SCR/SNCR injection lances and gas cooling. 316L provides excellent resistance to acidic flue gases, while 310S is optimized for high-temperature stability in furnace injection applications.
Hastelloy & High-Nickel Alloys
Specifically engineered for Marine Scrubbers (EGCS) and waste incineration plants. Hastelloy C-276 offers unparalleled protection against stress corrosion cracking and pitting in high-chloride, low-pH environments where standard steel fails.
Technical Ceramics (Alumina/Zirconia)
Designed for extreme thermal shock resistance in waste-to-energy plants and gas quenching systems. These materials maintain structural integrity at temperatures exceeding $1000°C, ensuring consistent spray patterns in the harshest heat.
Frequently Asked Questions
How do I choose the right nozzle for an FGD scrubber?
Selection depends on the Liquid-to-Gas (L/G) ratio and the slurry's solid content. For main spray banks, Silicon Carbide Spiral Nozzles are preferred due to their large free passage and superior wear resistance. For mist eliminator washing, wide-angle full cone nozzles ensure 100% coverage to prevent scale buildup.
What is the ideal droplet size for SNCR denitrification?
Effective NOx removal requires a fine droplet spectrum, typically between $50-120\ \mu m$ (Dv0.9). Smaller droplets evaporate faster, ensuring the reagent (ammonia/urea) reacts fully with the flue gas without causing "wet wall" corrosion in the duct.
How can I reduce maintenance costs in desulfurization systems?
Transitioning to clog-resistant designs like our Max Passage Full Cone Nozzles and using RBSC materials significantly reduces downtime. Regular inspection of spray patterns is also recommended to maintain optimal removal efficiency.
