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. |
