ABSTRACT:
In a vessel such as for a fluid coker burner, there is provided a plenum chamber which functions as a collection header for the clean gas discharge from a plurality of cyclone stages supported within the vessel. The plenum chamber comprises a cylindrically-shaped support skirt welded at one end to the vessel head and at the other end to a relatively thin, flat steel floor, no more than about three-sixteenths to five-eighths of an inch thick. Each of the cyclone stages are individually and separately supported by support means connected directly between each stage and the vessel head and the plenum chamber floor is welded to the cyclone stages, thereby supporting the floor. This permits use of a thinner plenum chamber floor which is capable of sustaining distortions which arise from the differential vertical thermal expansions of the cyclone stages during operation.
