PURPOSE:To prevent the abrasion of the end surface of a catalyst, by providing a plurality of metal nets to the upstream side of the catalyst bed in a denitration apparatus in a gas flow direction. CONSTITUTION:A plurality of metal nets 2 for distributing dust and preventing the abrasion of a catalyst are attached by amount support angle steels 3 so as to be positioned above the catalyst bed 5 arranged in the main body of a denitration reactor 4 and, when exhaust gas (containing dust) passes through the metal nets 2 from an exhaust gas inlet duct 1 in vertical flow, the offset stream and vortex stream of exhaust gas are distributed and, at the same time, dust is uniformly diffused to prevent the abrasion of the end surface of the catalyst. The metal nets may be arranged horizontally or in a zigzag pattern in a horizontal direction. |
