<P>PROBLEM TO BE SOLVED: To prevent dust having a large particle size that affects blocking and abrasion from piling up in a reactor by easily reducing the dust. <P>SOLUTION: The exhaust gas denitrification apparatus includes a denitrification reactor having a catalyst layer that removes nitrogen oxides in combustion exhaust gas. The exhaust gas denitrification apparatus includes a duct structure including a stub-up part at which the flow of exhaust gas changes from a horizontal direction to a vertical direction in an exhaust gas duct in the upstream side of the denitrification reactor. The exhaust gas denitrification apparatus further includes, in the duct in the horizontal direction of an inlet port of the stub-up part or/and in an inlet port of the catalyst layer in the denitrification reactor, a tilt thin plate slit in which a plurality of thin plates are arranged in a vertical direction with the slit width smaller than the open width of the catalyst layer and with a predetermined inclination angle relative to the cross section of an exhaust gas flow path, and a dust collecting/discharging part that is attached to the lower end of the tilt thin plate slit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
