Hybrid SNCR-SCR flue gas denitrification technology is not a simple combination of SCR process and SNCR process. It is a new process developed by combining the characteristics of SCR technology and SNCR technology with low investment. Brain et al. proposed that the SCR-SNCR combined technology can achieve a NOx removal rate of 90%, and the NH3 leakage rate is only 0.000 3%.
The main improvement of the hybrid SNCR-SCR process is to eliminate the complex AIG (ammonia injection) system of SCR set in the flue. It has the following advantages:
(1) While saving catalyst, the denitrification efficiency is high and can reach the denitrification efficiency of SCR method;
(2) The reaction tower is small in size and has strong spatial adaptability;
(3) Compared with the traditional SCR process, the system pressure drop will be greatly reduced, thereby reducing the workload of induced draft fan modification and reducing operating costs;
(4) Reduce corrosion hazards.

★FAQ

Q. How high is the dust removal efficiency of bag filters?
A. The dust removal efficiency can generally reach more than 99%, and can effectively filter fine dust above 0.3 microns.

Q. Can bag filter handle high temperature gas?
A. It can handle high temperature gas up to about 250℃. It needs to use high temperature resistant filter material and control the temperature and humidity of the gas.

Q. How to extend the service life of bag filter?
A. Choose appropriate filter material, clean dust on time, avoid high temperature shock and dust blockage, and perform regular inspection and maintenance.
