High Efficiency at Low Pressure SiC Nozzle

Spiral Nozzles – The Durable & Efficient Core Component for Desulfurization & Dust Removal
In large-scale industrial flue gas treatment systems, nozzle performance directly dictates the efficiency and operational cost of desulfurization and dust removal. The spiral nozzle, renowned for its unique design and superior material, has become the preferred solution for harsh operating conditions.
Core Technical Advantages: Clog-Free & Extreme Wear Resistance
The spiral nozzle gets its name from its unique internal helical flow channel design. The liquid (typically limestone slurry or process water) enters the nozzle tangentially, creating intense vortex motion inside before being discharged from the orifice, forming an evenly distributed solid cone or hollow cone spray pattern.
The key benefits of this design are:
  • No Internal Vane Structure: The unobstructed flow path minimizes clogging risks caused by impurities or slurry sedimentation, ensuring system stability.
  • High Efficiency at Low Pressure: Achieves high flow rates and excellent atomization even at low operating pressures, saving energy and reducing consumption.
Silicon Carbide Material: A Revolutionary Leap in Service Life
Nozzle longevity is crucial for economic viability. Spiral nozzles are manufactured from high-performance silicon carbide (SiC) ceramic, setting the industry benchmark:
  • Exceptionally Long Service Life: In the same abrasive desulfurization slurry environment, their service life is 10 to 20 times longer than ordinary metal nozzles (e.g., 316L stainless steel) and 4 to 7 times longer than standard alumina ceramic nozzles.
  • Outstanding Properties: Silicon carbide offers extreme hardness (above 9.2 Mohs), excellent resistance to acid/alkali corrosion, and high-temperature stability, making it perfectly suited for the extreme conditions of high abrasion, corrosion, and temperature inside desulfurization scrubbers.

4 Inch 90°, 120° 1690 2000
Note: Flow rate increases with operating pressure. Please refer to the product manual for specific performance curves.
Primary Application Areas
Spiral nozzles are critical components in flue gas purification systems for the following industries:
  • Coal-Fired Power Plants: Wet Flue Gas Desulfurization (WFGD) systems
  • Steel & Metallurgy Industry: Flue gas desulfurization and cooling for sinter machines, converters, and electric arc furnaces
  • Large Industrial Boilers: Tail gas treatment for boilers in chemical, pulp & paper, and other industries
  • Gas Scrubbers: Used for chemical absorption, gas cooling, and dust removal
Conclusion
Choosing a spiral nozzle is more than selecting a spray component; it is an investment in high reliability, low maintenance costs, and long-term stable operation. It is the ideal choice for achieving efficient environmental compliance in demanding industrial applications.
