Denitrification Spray Lance(DS Telescopic)
Denitrification Spray Lance (DS Telescopic) is a specialized industrial telescopic spray lance engineered for flue gas denitrification (SNCR) in boilers and combustion systems. It delivers uniform atomization with finely distributed droplets (average ~60 µm) across a wide flow range (≈3 – 400 L/h) for effective reagent evaporation and NOx reduction. Its telescopic extension mechanism allows the lance to extend into furnace or duct interiors during operation and retract when idle, enhancing safety and convenience. Built with corrosion-resistant stainless steel or alloy materials, it offers low operating cost, long service life, and flexible control options (local or remote). Suitable for coal-fired boilers, biomass boilers, cement kilns, glass kilns, and other high-temperature industrial combustion systems requiring environmental emissions control.
Design features
1. Uniform atomization – the particle size distribution in the entire spray area is uniform, which provides a very superior guarantee for the uniform evaporation and absorption reaction of the liquid. The average particle diameter is only 60μm, and the particle size shall not exceed 120μm
2. Lower operating cost – low gas-water ratio is the advantage of this spray gun, and long-term use can save operating costs
3. Wide flow range – the flow range is from 3L/h to 400L/h, which can meet various flow requirements
4. Long service life – because the nozzle works in a low-pressure environment, the water pressure and air pressure do not exceed 0.6Mpa, so the wear on the nozzle is very small, and the spray gun can also be equipped with a protective sleeve. The nozzle is placed in the protective sleeve, which can better protect the nozzle, thereby greatly extending the service life
5. Convenient operation – it can be controlled on-site or remotely controlled by the central control. It automatically extends to the furnace to spray when in use, and automatically exits the furnace when not in use
