ABSTRACT:
Apparatus for effecting high temperature catalytic conversion treatment of exhaust gases flowing in a large volume exhaust path comprising a plurality of separate catalyst panel assemblies, and a panel support assembly arranged to be mounted within the exhaust path and to separately removably support each of the plurality of catalyst panel assemblies so that high temperature exhaust gases within the exhaust path will flow therethrough in operation and each panel assembly can be conveniently serviced by simple removal. The panel support assembly includes an outer ambient temperature peripheral frame structure, an inner high temperature peripheral frame structure mounted within the outer peripheral frame structure for temperature responsive expansion and contraction with respect thereto, and an expansible and contractible high temperature resistant peripheral seal assembly between the inner and outer peripheral frame structures for maintaining a flow preventing seal therebetween. Each catalyst panel assembly is supported by an arrangement which includes doors openable to permit the catalyst panel assemblies to be removed. Each panel assembly includes a guarded high temperature resistant peripheral seal assembly for insuring that the flow of high temperature exhaust gases within the exhaust path is solely through the catalyst passages thereof.
