OSTI ID:6777390
This patent describes a method for maintaining a uniform mass flow rate of a particulate solids and gas mixture discharged from a holding vessel apparatus to a receiving reactor. It comprises: introducing the mixture into a first containing means having converging walls forming a portion made of porous material having at least one port formed at the apex thereof for discharging the mixture therefrom; isolating areas outside the porous material portion of the first containing means to form at least two substantially closed compartments; selectively injecting gaseous fluid under pressure into each of the compartments; independently controlling the flow rate and direction of the gaseous fluid under pressure at a rate sufficient to aerate the particulate solids in proximity to the portion of porous material but at a rate below that which would fluidize the particulate solids located above the porous material; and discharging the particulate solids and gas mixture from the first containing means through a conduit.
