Denitrification Spray Lance(CSMM Series)

Denitrification Spray Lance (CSMM Series) is an industrial spray lance for flue gas denitrification and NOx reduction systems that delivers fine, evenly distributed atomized spray with low air consumption and wide spray coverage. Featuring a simple, clog‑resistant design and optimized air‑water mixing structure, it minimizes particle size variations and improves spraying efficiency while reducing maintenance needs. Constructed from corrosion‑resistant materials such as 303, 316, or 310 stainless steel (with optional Hastelloy), the CSMM Series is suitable for environmental protection applications in boilers, power plants, cement plants, and other high‑temperature combustion environments. In addition, stable atomization performance ensures consistent spray coverage and reliable operation under varying furnace conditions, further improving overall system efficiency.

Categories: Spray Lances

Material: 303, 310, 316SS

Product features:

1. Simple structure, easy maintenance: The overall structural design is concise, resistant to clogging, easy to disassemble and assemble, and requires low maintenance, making it suitable for long-term stable operation.

2. Strong anti-clogging performance: The flow channel is designed reasonably to prevent crystallization or clogging, adapting to complex flue gas and operating conditions.

3. Good atomization uniformity: The spray is evenly distributed with excellent liquid coverage, facilitating full diffusion and reaction of the reducing agent inside the furnace.

4. Low air consumption design: Reduces compressed air usage while maintaining atomization performance, improving the system’s operational economy.

5. Wide spray coverage: The spray covers a large area, meeting the requirements of different furnace types and operating conditions for the injection zone.

6. Fine and stable droplets: The droplet particle size is small and evenly distributed, allowing rapid evaporation and improving denitration reaction efficiency.

7. Efficient atomization at low air-to-liquid ratio: Achieves excellent atomization performance even under low air-to-liquid ratio conditions, balancing performance and energy savings.

8. Long service life: The optimized gas-liquid mixing structure reduces internal wear, enhances durability, and extends the operational lifespan.

9. Flexible material selection: Supports materials such as 303, 316, and 310 stainless steel, with custom options available for Hastelloy alloys, suitable for high-temperature and corrosive environments.

Application:

Suitable for SNCR denitration systems in industrial furnaces and kilns such as cement plants, power plants, steel plants, and waste incineration plants. Widely used in furnace types including chain furnaces, pulverized coal furnaces, and circulating fluidized bed boilers.

Also suitable for flue gas denitration, flue gas conditioning, and other operating conditions requiring high-efficiency atomized spray. It can operate stably under high-temperature, high-dust, and corrosive flue gas conditions, meeting industrial requirements for NOx emission reduction and environmental compliance.
