Abstract
A system is provided with a segmented solid feed pump having a plurality of pump segments disposed along a closed-loop path. The plurality of pump segments are coupled together in series along the closed-loop path, and the plurality of pump segments move along the closed-loop path. Furthermore, each pump segment includes a holding receptacle.
Claims25
A system, comprising:
- a segmented solid feed pump, comprising:
- a closed-loop path;
- and
- a plurality of pump segments coupled together in series along an axis of the closed-loop path, wherein each pump segment comprises a carriage having a holding receptacle defined by a bottom wall, a top, opposite side walls extending between the bottom wall and the top, and at least one axial end opening extending from the top to the bottom wall along the opposite side walls, and the plurality of pump segments move along the closed-loop path.
