PROBLEM TO BE SOLVED: To easily and additionally provide a denitration pack to an existing exhaust heat recovery boiler.SOLUTION: There is provided a carrying-in system 100 for a denitration pack for an exhaust heat recovery boiler which additionally provides a denitration function to the exhaust heat recovery boiler by carrying in plural denitration packs 30, in which a NOx removal catalyst is filled through an opening 20, in a casing 14 of the exhaust heat recovery boiler 10 in which a heat transfer pipe group 12 including plural heat transfer pipes 11 extending in a horizontal direction is provided in an exhaust gas passage 13. The system 100 is equipped with: a denitration pack moving mechanism 110 which moves the denitration packs to a predetermined position on either a top side or a bottom side of the heat transfer pipe group; and a seal plate 102 which has an inflow hole 104 for flowing exhaust gas flowing through the exhaust gas passage 13 into the denitration packs 30 and seals an outer edge 30a of the bottom face or the top face of each denitration pack 30. The denitration pack 30 has a size such that the pack can be carried in the casing through the opening. Further, the denitration pack, the denitration pack moving mechanism and the seal plate are carried-in through the opening when carried in the casing. |
