Flow control device for solid particulate material |
摘要 |
A flow control device for solid particulate material such as recycled granular solids utilized in a fluidized bed combustion vessel includes a generally horizontal material feeder conduit having an outlet end in communication with the fluidized bed of the combustion vessel and a receiving end remote therefrom. An upstanding material collector conduit having a lower end in communication with a receiving end of the feeder conduit is provided and an upper end of the collector conduit is adapted to receive a flow of particulate solid material to be fed at a controlled flow rate into the combustion vessel. The upstanding collector conduit forms a standpipe for retaining a quantity of material to establish a pressure sealing head or column of material extending upwardly of the receiving end of the feeder conduit. A gas assisted flow initiator and controller extends into the feeder conduit for directing a flow of pressurized gas into the solid particulate material to fluidize the same for travel into the combustion vessel at a selected flow rate.
