摘要： A system for processing fine powders includes a hopper for dispensing powder material through a hopper outlet, and a feeding chamber positioned downstream of the hopper outlet to receive the powder material and convey the powder material to a plasma torch. The system also includes an auger positioned at the hopper outlet, a mechanical vibrator and a mesh screen attached to a flange of the feeding chamber, and a pneumatic system providing a gas flow sufficient to propel the powder material without extinguishing a plasma of the plasma torch.

摘要： A conveyor for pulverized material comprises in combination a conduit, a screw rotatably mounted within the conduit having a material inlet end and material discharge end, means for rotating the screw, means for supplying material to the screw at the material inlet end, whereby the material will be compacted as it is advanced by the screw to the material discharge end, and means for admitting a gas under pressure to the compacted material at the material discharge end to render it fluent. In a portion of the screw a material seal is formed by the compacted material being advanced by the screw, wherein there are material pockets formed between adjacent screw flights, wherein the pocket size volume is at its maximum nearest the material inlet end and at its minimum nearest the material outlet end, with at least twice as many pockets of minimum size as of maximum size.

摘要： This invention is about a coal feeding system (1) which feeds pulverized coal and oxygen separately and vertically through concentric pipes directly to the upper level of the reactor (R) at entrained flow gasification systems. The system (1) consists a top intake (2), a side intake (3), an air supply chamber (4), an oxygen port (5), an ultrasonic sensor port (6), an inner concentric pipe (7), and an outer concentric pipe (8). The system (1) also operates with a coal bunker (K), a screw feeder (B) for adjusting the coal mass flow rate from the coal bunker (K) through the coal feeding system (1) to the reactor (R), and a reactor (R) where the coal are sprayed from the coal feeding system (1) and gasified at high temperatures.

摘要： 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.

摘要： A feeder apparatus supplies a powder feedstock to a high or low pressure processing operation. The apparatus includes a metering plate defining an annular channel having a channel width. A measuring mechanism dispenses a measured volume of the feedstock into the annular channel. The measuring mechanism includes a pay-out device defining an outlet significantly smaller than the channel width. The measuring mechanism further includes a maximum fill level defining a maximum pressure head in the feedstock less than a retaining pressure defined by the internal friction of the feedstock. The restraining pressure prevents the feedstock from spreading outwardly in the annular channel and contacting sidewalls of the annular channel under the pressure head of the feedstock. The apparatus further includes a pick-up device for removing the feedstock from the annular channel. The pick-up device includes an inlet having a rectangular shape extending across the annular channel.
