Description of the Related Art As a method for removing nitrogen oxides in combustion exhaust gas discharged from a boiler, a catalytic reduction method using ammonia as a reducing agent has been widely adopted. Various characteristics are required for the nitrogen oxide removing catalyst (hereinafter, referred to as a denitration catalyst) used for this. One property is low dust accumulation. This property requires that when dust contained in the exhaust gas accumulates on the denitration catalyst layer, the pressure loss increases, making it difficult for the exhaust gas to flow and reducing the effective contact area of the catalyst.

After applying the catalyst paste to which the catalyst paste is added, the catalyst paste is formed into a predetermined shape (for example, a corrugated plate having a constant pitch), and thereafter, a denitration catalyst is used in which a large number of plate catalysts dried and fired are laminated.

け正確に揃っていることが必要である。[0005] As a method for producing the plate-like catalyst, there is an unknown Japanese Patent Application No. 2-74814 filed by the present inventors. In the manufacturing method of this application, after applying a catalyst paste to a continuous inorganic fiber woven fabric having a predetermined width, the catalyst paste is cut into a plate-like body having a desired width and length, and supplied to a molding machine to be formed. After that, drying and firing are performed. When the corrugated catalysts are used in a laminated state, if the positions of the formed waveforms are not aligned with the peripheral side of the plate-like body, the laminated waves will shift in position, and a stable laminated body cannot be formed. For this reason, it is necessary that the shapes and dimensions of the cut plate-like bodies are as accurate as possible.
