Abstract: A vertical downflow type flue gas denitrification apparatus which has a plurality of catalyst blocks, each incorporating a catalyst unit provided therein, is provided with a first ash accumulation baffle plate and a second ash accumulation baffle plate which are slidable into a gap between catalyst blocks adjacent to each other, and processes an exhaust gas emitted from a combustor and turned to a vertical downflow. The denitrification apparatus has a simple configuration where the ash accumulation baffle plates prevent ash or the like from being accumulated in the gap between the catalyst blocks. The thermal expansion of the ash accumulation baffle plate can be absorbed even under the operating conditions which produce a change in temperature, and charging and replacing the catalyst in the catalyst blocks are possible without on-site welding of the ash accumulation baffle plates.
