Aeration apparatus for discharge control of particulate matter
This paper describes an apparatus for maintaining a uniform mass flow rate of a particulate solids and gas mixture discharged from a holding vessel to a receiving reactor. It comprises: means for introducing the mixture into a containing means, the containing means being located within the holding vessel and having a downwardly converging wall which forms at least one port at the apex thereof for discharging the mixture therefrom; first tubular aeration means fixedly secured within the containing means and in axial alignment with the discharge port for aerating the mixture; second aeration means fixedly secured to the first aeration means for aerating the mixture in a direction opposed to that of the first aeration means; first and second gaseous fluid supplies for providing gaseous fluids to the first and second aeration means respectively; first and second means for selectively injecting the gaseous fluids under pressure into the first and second aeration means; means, in the first and second aeration means, for discharging the gaseous fluids into the particulate solids and gas mixture; and means for discharging the particulate solids from the first containing means.
