<p>PURPOSE:To prevent the deviation of catalysts at the time of filling and removing and decrease their damages by mounting L-shaped heat-resistant packings to the side edge parts of the gas passage holes of the catalysts, fixing the same by means of retaining fittings from the outer side of the packing material of single catalysts. CONSTITUTION:Heat-resistant packings 2 of an L-shape formed by ''Kaowool '', asbestos, etc. are disposed on the upper stream side and lower stream side of the gas passage surfaces of single catalyst layers 1, and the catalysts 1 and heat-resistant packings 2 are alternately combined and stacked, whereby these are packaged into one body. Further, retaining fittings 4 are applied from the outer side of the packing materials 2 at said side edge parts on at least one side of the gas inlet side or outlet side of the gas passage surfaces of the single catalysts and the fittings 4 are fixed to a frame structural body 5. The packings 2 are used at about 2-3mm. thicknesses corresponding to the thickness of the outside wall part of the catalysts in order to provide protection to the end face parts of the catalysts 1 and prevent the deviation of the catalysts in the direction perpendicular to the gas flow 3.</p> |
