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).

Wheeled SCR sealing mechanism

An SCR reactor sealing mechanism is disclosed which utilizes a clamping plate (34) to urge a side sealing flange (24) on a member (20) containing the catalyst (22) against a mating sealing surface (32) on the supporting internal frame (12) to prevent exhaust gas from bypassing the catalyst. The sealing mechanism has an advantage in permitting the member and catalyst to be removed from the internal frame by simply loosening the clamping plate (34) and slid out of or into the internal frame.
