AI Technical Summary
Technical Problem
In existing SNCR denitrification technologies for waste incineration boilers, the use of urea or ammonia as reducing agents presents problems such as high energy consumption, high risk of ammonia escape, and low denitrification efficiency.
Method used
Dry powder denitrification agent is used, which is mixed with high-temperature flue gas through a cyclone separator. Ammonium carbamate decomposes into ammonia at around 200℃. The ammonia reacts with nitrogen oxides in the flue gas in the cyclone separator to improve the denitrification efficiency.
Benefits of technology
Reduce ammonia production energy consumption, decrease the risk of ammonia escape, improve denitrification efficiency, simplify the system, and reduce transportation and storage safety hazards.
