ABSTRACT:
A system for substantially continuously providing a solid material, for example pulverized coal, to a pressurized container. The system provides the solid material to a first container of a first pressure elevated above an initial pressure of the solid material. Generally, a screw conveyor augmented with a jet port is used to move the material where the jet port provides a gas to provide a make-up volume of the solid material. The system also provides the material to a second high pressure container after the material has been formed into a slurry. Therefore, the solid material may be substantially continuously provided in a system to a high pressure container.
