Summary:The present invention provides a smoke exhaust denitrification device. The smoke exhaust denitrification device supplies the Ammonia gas to the confluence exhaust gas formed of the main stream exhaust gas and the bypass exhaust gas, and then a denitrification reactor precedes the denitrification. The main stream exhaust gas reduces its temperature by a heat economizer 22 when flowing through a main stream conduit 16, while a bypass exhaust gas 28 is kept at a high temperature when flowing through a bypass conduit 24 of the bypass heat economizer 22. Especially, the confluence part of the main stream exhaust gas 26 and the bypass exhaust gas 28 of the main stream conduit 16 has three separation plates 44. The separation plates 44 are parallel to the flowing direction of the main stream exhaust gas 26, and separate the flowing path of the main stream exhaust gas into plural portions. Also, the plate surfaces of the separation plates 44 are opposed to the flowing direction of the bypass exhaust gas 28. The separ
