A solids supply system having a solids deaeration zone and a solids pump zone, and a method for supplying the solids e.g., pulverized dry coal, to an application, e.g., gasification process. The solids deaeration zone includes a container having a passageway defined by one or more sloped walls. The solids deaeration zone is operable to deaerate and convey the solids to the solids pump zone. In the solids deaeration zone, the solids become sufficiently compacted prior to and upon entry into the solids pump zone to be effectively conveyed through the solids pump zone. L'invention porte sur un système d'amenée de solides ayant une zone de désaération des solides et une zone de pompage des solides et sur un procédé pour amener les solides, par exemple du charbon sec pulvérisé, à une application, par exemple à une opération de gazéification. La zone de désaération des solides comprend un récipient ayant un passage défini par une ou plusieurs parois inclinées. La zone de désaération des solides peut être mise en action pour désaérer et transporter les solides jusqu'à une zone de pompage des solides. Dans la zone de désaération des solides, les solides sont suffisamment compactés avant leur entrée dans la zone de pompage des solides et au moment de leur entrée dans cette zone pour être efficacement transportés à travers la zone de pompage de solides.
