To provide a flue gas denitration apparatus capable of effectively collecting massive ash contained in a flue gas and automatically and completely discharging the collected massive ash while reducing maintenance cost.
The flue gas denitration apparatus is for removing nitrogen oxide contained in the flue gas produced in a coal-burning boiler B and is provided with: a denitration catalyst 12; a guide vane 13 arranged to be inclined against the flow of the flue gas in the upstream side of the denitration catalyst 12 and changing the advancing direction of the massive ash; a collecting part 14 positioned between the guide vane 13 and the denitration catalyst 12 to collect only the massive ash the advancing direction of which is changed by the guide vane 13 while passing the flue gas; a transporting pipe line 22 connecting the collecting part 14 to an external container 21 to which the massive ash collected in the collecting part 14 is transported; and a transporting mechanism 20 possessing a communicating pipe 23 having one end connected to the container 21 and the other end opened in the downstream side of the denitration catalyst 12.
