CONTROL OF SOLIDS DISCHARGED FROM PRESSURIZED VESSEL

摘要

CONTROL OF SOLIDS DISCHARGE FROM PRESSURIZED VESSEL Control of discharge of particulate solids from a pressurized vessel is attained through a downwardly directed conduit with or without the use of valves. The lower end of the conduit has a greater cross-sectional area than the upper end of the conduit. The lower end of the conduit may extend into a fluidized bed. Discharge of solids from the vessel may be controlled by controlling the height and degree of aeration of the fluidized bed.
