ABSTRACT:
A degaser is disclosed for an outlet conduit into which solids are transferred from a fluidized bed within a larger vessel and comprises a curvilinear wall extending upward from the upper end of the outlet conduit and beveled at an angle to the vertical to form an outlet with a rim having a high side and a low side. The degaser is positioned with its high side far below the solids inlet into the vessel and its low side near the bottom of the fluidized bed. The biased rim may take various shapes and the degaser wall may extend only partially around the upper conduit end. Fluidizing gas can be introduced into the bed either above or below the low side of the degaser. The degaser may also include a baffle arranged within the vessel in cooperative relation to the rim.
