B65G 15/00
B65G 11/00

US Classification:

198523, 193 2 R

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.

International Classification:

F23C 10/00

Abstract:

Methods and devices for combusting a carbonaceous fuel in an oxy-combustion fluidized bed reactor involving controlling the local oxygen content within the oxy-combustion reactor to specified levels. The carbonaceous fuel and an oxygen-containing gas are introduced into a fluidized bed reactor and eluted through a fluidized bed of an inert material, dolomite or a combination thereof to combust the fuel and oxygen to produce at least COand steam. The oxygen-containing gas is a mixture of oxygen, recycled COand steam and has sufficient oxygen added to the recycled COand steam that the mixture contains 7-20 mole % oxygen. The carbonaceous fuel and the oxygen-containing gas are introduced into the fluidized bed at a location in sufficiently close proximity to each other to avoid producing a reducing atmosphere at the location. At least a portion of the produced COand steam are recycled to the reactor.

F23K 3/02

Abstract:

Methods, devices and systems for processing of solid materials, particularly fuel material solids such as carbonaceous fuel solids such as of granular form, to provide or result in an even distribution of the solid material. Hoppers are provided with plurality of outlet orifices, each of the outlet orifices adapted to flow therethrough a combination of gas and the solid material to pneumatically convey the solid material to a distribution manifold. The distribution manifold includes a plurality of tubes with each tube having a plurality of exit orifices wherein each exit orifice passes an equal portion of the combination of the gas and the solid material.
