Utilizing Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) technologies, our system ensures NOx reduction efficiency of 90%+, meeting global environmental standards such as EPA, EU Industrial Emissions Directive (IED), and China's Ultra-Low Emission (ULE) policies.
What are the advantages of high concentration Nox Flue Waste Gas Treatment Equipment System?
The high concentration Nox Flue Waste Gas Treatment Equipment System can effectively achieve a high concentration nitrogen oxide removal rate of up to 98%, extremely low ammonia escape, significant energy saving, and intelligent control to reduce costs and increase efficiency.
Ultra-High Efficiency: Advanced SCR/SNCR hybrid technology ensures NOx reduction rates of 90-98%, even for flue gases with NOx >1000mg/Nm³.
Low Ammonia Slip: Patented ammonia injection grid (AIG) minimizes NH₃ slip to <3ppm, reducing secondary pollution.
Energy-Efficient Design: Low-pressure drop catalyst modules reduce fan power consumption by 20%.
Modular & Scalable: Customizable for small boilers (10,000 Nm³/h) to large power plants (1,000,000+ Nm³/h).
Smart Control System: AI-based NOx prediction optimizes reagent dosing, reducing operational costs by 15%
What is the principle of high concentration Nox Flue Waste Gas Treatment Equipment System?
High concentration Nox Flue Waste Gas Treatment Equipment System adopts selective catalytic reduction (SCR) and non-catalytic reduction (SNCR) two-stage nitrogen oxide emission reduction technology:
Selective Catalytic Reduction (SCR): NOx + NH₃ (urea) → N₂ + H₂O (over a TiO₂/V₂O₅/WO₃ catalyst at 300-400°C).
Best for stable high-load operations (e.g., coal-fired power plants).
Selective Non-Catalytic Reduction (SNCR): NOx + NH₃ → N₂ + H₂O (at 900-1100°C without a catalyst).
Ideal for fluctuating loads (e.g., waste incinerators, cement kilns).
Hybrid Mode: Combines SCR (for baseline NOx) + SNCR (for peak loads) to maximize efficiency
