Claims

[Scope of utility model registration request]

In an apparatus for providing a shelf in an exhaust gas passage and arranging dry _NH3 catalytic reduction catalysts on the shelf, the device is removably installed on the shelf and is formed from a steel plate to allow the exhaust gas to pass from one end to the other end. a cylindrical body, and a plurality of lattice-shaped catalyst receiving shelves, which are provided within the cylindrical body to intersect with the exhaust gas flow flowing therethrough and are spaced apart from each other by appropriate intervals, and on which the reduction catalyst is placed and through which the exhaust gas passes. and a ceramic buffer material interposed between the inner wall of the cylinder and the charged reduction catalyst.
