Abstract
According to various embodiments, a system includes a solid feed pump. The solid feed pump includes a housing, a rotor disposed in the housing, a curved passage disposed between the rotor and the housing, an inlet coupled to the curved passage, an outlet coupled to the curved passage, a solid feed guide extending across the curved passage, and a thermal control path through a portion of the solid feed pump.
Claims20
A system, comprising:
- a solid feed pump, comprising:
- a housing;
- a rotor disposed in the housing;
- a curved passage disposed between the rotor and the housing, wherein the curved passage is configured for transport of a solid feed through the curved passage;
- a solid feed inlet coupled to the curved passage;
- a solid feed outlet coupled to the curved passage;
- a solid feed guide extending into and across the curved passage and/or against the rotor, wherein the solid feed guide is disposed adjacent the solid feed outlet, and the solid feed guide comprises a guide wall that substantially blocks the curved passage adjacent the solid feed outlet;
- and
- a thermal control path through a portion of the solid feed pump, wherein the thermal control path extends through, along, or around at least one of the solid feed guide, the solid feed outlet, or the rotor.
6 more elements
A system, comprising:
- a solid feed pump, comprising:
- an internal feed passage;
- an solid feed inlet coupled to the internal feed passage;
- an solid feed outlet coupled to the internal feed passage;
- an inert fluid path through the solid feed pump;
- and
- a gas recirculation system coupled to the inert fluid path, wherein the gas recirculation system is configured to couple with a solid feed path upstream from the solid feed pump, a solid transport path downstream from the solid feed pump, or a combination thereof, wherein the gas recirculation system is coupled to a solid feed bin or a solid feed hopper in the solid feed path, a buffer chamber in the solid transport path, or a combination thereof.
