SiSiC desulfurization spray nozzles are reaction bonded silicon carbide (RBSiC) components designed for flue gas desulfurization (FGD) towers in coal-fired power plants, steel mills, chemical plants, and incineration systems. These nozzles endure high-speed slurry spray, corrosive gases, and fine particulate erosion over long operating cycles.

Compared with traditional alloy or plastic nozzles, SiSiC nozzles offer superior wear resistance, chemical inertness, and high temperature stability, making them ideal for wet scrubber environments where lime, limestone slurry, or other desulfurization agents are sprayed into gas streams.

3 Inch Silicon Carbide Spray Nozzle

The 3-inch SiSiC spray nozzle is designed for high flow rates and uniform spray distribution, ideal for industrial desulfurization and gas scrubbing. Its robust build ensures long service life in chemically aggressive and particulate-laden environments.

Commonly used in power plant towers, boilers, and sintering systems, these nozzles are made from reaction bonded SiC or stainless steel 316L, offering high strength, hardness, and corrosion resistance at elevated temperatures.

3 Inch SiSiC Spray Nozzle

Under pressure, liquid flows through the RBSC/SiSiC spiral nozzle, striking the spiral surface and redirecting into a cone-shaped spray. This design increases the coverage area effectively by adjusting the helix angle across layers.

The nozzle produces both hollow and solid cone sprays with spiral angles from 60° to 170°. Its internal structure allows a significantly larger free passage than traditional nozzles, minimizing clogging and optimizing spray efficiency.

Key Advantages

Silicon carbide products are an advanced material widely used in high temperature, high pressure and high frequency environments.:

High Strength

Composite structure with ordinary steel outer wall meets strength requirements for various industrial processes.

Exceptional Wear Resistance

Inner ceramic layer (≥95% content) provides 30x better wear resistance than carbon steel pipes.

Corrosion Immunity

Corrosion-resistant composite layer enables use in acid, alkali, and salt environments.

High Bond Strength

Organic polymer matrix with inorganic ceramic reinforcement provides 14-16 MPa peeling strength (100x stronger than ordinary lining).

Wide Temperature Range

Continuous operation from 40°C to 200°C, with peak resistance up to 260°C.

Extended Service Life

Elbows show no significant wear after 1-2 years, outperforming thick-walled cast steel by nearly 10x.

Performance Comparison

Silicon carbide ceramic-lined pipes offer superior performance compared to traditional materials:

  • Carbon Steel Pipes 30x less wear resistance
  • Wear-Resistant Alloy Cast Steel 10x less wear resistance
  • Cast Stone Pipes Brittle, prone to cracking
  • Rubber-Lined Pipes Limited temperature resistance
