Summary:PROBLEM TO BE SOLVED: To stably operate a denitrizer by suppressing accumulation of compounds of non-evaporated ammonia generated near downstream of an ammonium injection nozzle in a flue gas duct and ash accumulated on the duct bottom. SOLUTION: An ash accumulation preventive soot blower 10 is installed at an appropriate point on the duct lower wall 6a of a rear flow part of the nozzle 8, when injecting ammonia into the inlet flue 6 of a flue gas treatment facility from the injection nozzle 8. Ash accumulation preventive straightening plates 11a, 11b are installed before and after the soot blower for preventing the ash accumulation generated before and after the flue gas flow direction of the soot blower 10 body.
