Abstract:

A system includes a fluidization device including a flow passage configured to convey a flow of solid fuel particles in a downstream direction, and a body disposed within the flow passage. The body is configured to direct the flow of solid fuel particles between the body and an outer wall of the flow passage. The fluidization device also includes a carrier gas injection port positioned radially outward from the body. The carrier gas injection port is configured to provide a flow of carrier gas in the downstream direction to break up agglomerations within the flow of solid fuel particles.

International Classification:

C10J 3/20

US Classification:

48 85

Abstract:

A gasifier includes a combustion chamber in which a combustible fuel is burned to produce a syngas and a particulated solid residue. A cooling chamber having a liquid coolant is disposed downstream of the combustion chamber. A dip tube is disposed coupling the combustion chamber to the cooling chamber. The syngas is directed from the combustion chamber to the cooling chamber via the dip tube to contact the liquid coolant and produce a cooled syngas. An asymmetric or symmetric liquid separator is disposed proximate to an exit path of the cooling chamber and configured to remove entrained liquid content from the cooled syngas directed through the annular passage to the exit path.
