間をなくし脱硝効率の向上を果たすことができる。Further, since the cushioning material (4) is wound around the peripheral surface of each catalyst element (5), even if the storage frame and the catalyst element have dimensional tolerances, these tolerances are absorbed by the cushioning material (4). In addition, the difference in thermal expansion between the storage frame and the element can be absorbed by the cushioning material (4). As a result, it is possible to eliminate the gap between the catalyst elements and the gap between the storage frame and the element, thereby improving the denitration efficiency.
