PROBLEM TO BE SOLVED: To provide the clogging preventing device of a denitration apparatus, capable of preventing the deposition of particles of soot on the denitration catalyst charged in a denitration reactor to prevent the clogging of the nitration catalyst, capable of extending a cleaning interval to extend a boiler continuous operation time and capable of reducing the power cost of a push-in blower for sending combustion air under pressure. SOLUTION: A filter 6 utilizing a fine mesh metal net or the like for collecting particles of soot contained in exhaust gas is provided on the inlet side of a denitration reactor 3. Also, a jet nozzle 7, which ejects a soot blowing medium such as steam or the like from the downstream side of the filter 6 to the upstream side thereof to blow off particles of soot collected by the filter 6, and a soot suction machine 8, which sucks particles of soot blown off by the soot blowing medium ejected from the jet nozzle 7, are arranged. |
