摘要： PURPOSE: To facilitate the maintenance and inspection of catalyst panel assemblies by positioning a series of the catalyst panel assemblies through openings to operating positions within peripheral marginal frame structures and making the assemblies removable from these operating positions. CONSTITUTION: The accepting space of a panel supporting assembly 14 is formed to sizes and shapes for horizontally supporting a series of the catalyst panel assemblies 12 in the perpendicularly spaced operating positions at the same size. A door assembly 36 for opening and closing the opening 34 progressively advanceably moves the plural assembles 12 toward the respective operating positions, makes the assemblies progressively advanceably removable from the respective operating positions and makes the assemblies closable to restrain other side parts 18 in the other pairing side parts 16 of the respective assemblies 36 position in the respective operating positions of the accepting spaces. Consequently, the easy execution of the maintenance and inspection of the catalyst panel assemblies is made possible.

摘要： PURPOSE: To enable individual removal of blocks from upstream side and downstream side restraining members when a catalyst apparatus is no longer usable by securely restraining catalyst blocks into adjacent spaces by means of frame part members and these restraining members. CONSTITUTION: The catalyst blocks 22 are formed of opposite marginal parts on the upstream side and downstream side and are provided with nearly rectangular peripheral parts extending toward flow passages. Further, the blocks have the spatially disposed upstream side and downstream side blocks restraining devices 30, 32, 34, 36 which extend into the adjacent spaces along the upstream side and downstream side marginal parts of the blocks 20. The blocks 22 are securely restrained into the adjacent spaces by means of the frame members and the upstream side and downstream side restraining members in the prescribed juxtaposed processing positions so as to allow the exhaust gases to flow in the flow passages without securely adhering the blocks to the frame member and the upstream side and downstream side restraining members. Consequently, the perfect removal of respective blocks is made possible at the time of catalyst exchange.
