Abstract
An SCR reactor (50) is disclosed which permits ready removal of a catalyst bed (58) from the SCR reactor and provides an effecting sealing mechanism between the catalyst bed (58) and the frame (52) of the SCR reactor. The frame is provided with side rails (54, 56) which have individual indentations spaced therealong. The catalyst bed is provided with wheels (60A, 60B, 60C) along its length which permit the catalyst bed to be rolled along the side rails until the catalyst bed is moved into its installed position whereupon the wheels descend into the indentations (62), causing the weight of the catalyst bed to form an effective seal between a downwardly face edge (64) on the catalyst bed and the frame (52).
