A system including a quench system that may cool a syngas generated in a gasification chamber. The quench system includes a quench chamber, a dip tube that may direct the syngas from the gasification chamber into a quench liquid in the quench chamber to cool the syngas and to generate a first cooled syngas, and a draft tube disposed circumferentially about the dip tube and configured to receive the first cooled syngas in a first direction along a first passage. The first passage is disposed between a first wall of the dip tube and a second wall of the draft tube. The quench system also includes a droplet tube that may receive the first cooled syngas from the first passage. The droplet tube includes a third wall that may redirect a flow of the first cooled syngas in a second direction different from the first direction.

Gasification quench system

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.

Fluidization device for solid fuel particles

In one embodiment, a system includes a posimetric pump guide configured to mount in a port of a posimetric pump. The posimetric pump guide includes a first flow splitter defining first and second distribution channels into first and second passages in the posimetric pump. The first flow splitter includes a first pair of shroud walls spaced apart about a first disc opening. The posimetric pump guide also includes an abutment extending crosswise to the first flow splitter.
