The utility model provides a flue mixer structure for SNCR denitration of pulverized coal boiler flue gas, which uses a simple-structured and efficient flue gas/reducing agent mixer structure body in a proper area in the flue of the pulverized coal boiler, so that flue gas wrapped with a reducing agent can be fully mixed when flowing through the flue gas, thereby improving the SNCR denitration reaction efficiency; the device overall design is comparatively simple, and the region that internal devices such as the no screen heat exchanger exists in usable flue is directly arranged, and is very little to the change of flue structure, can gain better economic benefits and social. |
