PROBLEM TO BE SOLVED: To prevent a blowoff of a waste gas by a convenient method which does not depend on a welding work even at the time of packing or replacing a catalyst and also to realize a sealed structure preventing a generation of the blowoff of the waste gas between catalyst blocks in a denitration reactor even under a condition in which a rapid temp. change is generated. SOLUTION: Untreated waste gas flow leaked from a gap of the catalyst blocks is prevented by covering the gap between the catalyst blocks and a front end of its left and right catalyst blocks with a plate 3 for preventing the blowoff and calmping and fixing the plate with a bolt 5.nut 8. A sealed part is not deformed or released since it does not restrict deformation like a seal bar mounted by welding even at the time when the gap between the catalyst blocks 2 is about to deform because of a variation in shrinkage due to a heat between the catalyst blocks 2. |
