Abstract
A deconsolidation device defines a flow path with an inlet which defines a first cross-section generally equivalent to a passageway cross-section of a particulate material extrusion pump and an outlet that defines a second cross-section different than the first cross-section.
Claims12
A particulate material extrusion pump, comprising
- a vertical passageway including a moving vertical wall, said passageway defines a passageway cross-section;
- and
- a deconsolidation device having a stationary non-linear flow path extending from an inlet connected to the vertical passageway to an outlet, said inlet defines a first cross-section generally equivalent to said passageway cross-section and said outlet defines an exit for deconsolidated particulate and has a second cross-section different than said first cross-section.
A process of deconsolidating a pulverized carbon-based fuel comprising:
- conveying compressed particulate along a passageway in a direction;
- and
- changing from the direction of the compressed particulate to a non-linear flow path having an intrados and an extrados that extends between an inlet that communicates with the passageway and an outlet downstream from the inlet, and turning the compressed particulate through a turning angle provided between the inlet and outlet which defines an angle less than said angle of repose, wherein the direction is generally linear, wherein changing the direction occurs downstream of the passageway which includes a moving wall.
