A gasification quench chamber dip tube component is disclosed. The dip tube includes an elongate hollow element that has a first intake end and a second discharge end that is located distally opposite the intake end. The second discharge end includes either a plurality of elongate openings that are displaced circumferentially around the hollow element or a plurality of elongate elements displaced circumferentially around the hollow element thereby defining a plurality of elongate spaces therebetween that extend axially from the second discharge end. A quench chamber that employs the dip tube is also disclosed.

Gasification quench chamber dip tube

A gasification quench chamber is disclosed. The gasification quench chamber includes a reservoir that contains liquid coolant in its lower portion and an exit for the cooled syngas in its upper portion; a dip tube that is configured to introduce a syngas mixture to contact the liquid coolant which produces the cooled syngas; a cooling device configured to further cool the cooled syngas in its upper portion; and a stability device in the lower portion that is configured to mitigate coolant level fluctuation and sloshing. In an embodiment of the quench chamber, the cooling device includes a heat exchanger pipe. A quench chamber and scrubber assembly is also disclosed.

Gasification quench chamber and scrubber assembly

In one embodiment, a gasification system component, such as a quench unit or scrubber may retain of pool of a cooling fluid for cooling another fluid. The gasification system component includes a flow damping mechanism designed to dampen flow of the cooling fluid, the other fluid, or both, within the gasification system component. The flow damping mechanism may be disposed in an inner chamber formed between a dip tube and a draft tube or disposed in an outer chamber formed between the walls of the gasification system component and the draft tube. The flow damping mechanism also may be disposed between the inner chamber and the outer chamber.

Gasification system flow damping

A gasifier includes a combustion chamber in which a fuel is burned to produce a syngas and a particulated solid residue. A quench chamber is disposed downstream of the combustion chamber. A dip tube is disposed coupling the combustion chamber to the quench chamber. The syngas is directed to contact liquid coolant in the quench chamber and produce a cooled syngas. A draft tube is disposed surrounding the dip tube such that an annular passage is formed. A baffle is disposed proximate to an exit path of the quench chamber. The cooled syngas is directed through the annular passage and impacted against the baffle so as to remove entrained liquid content from the cooled syngas before it is directed through the exit path. A cross sectional area of the annular passage is larger towards the bottom of the quench chamber and smaller towards the top of the quench chamber.

Quench chamber assembly for a gasifier

A gasifier includes a combustion chamber in which a fuel is burned to produce a syngas and a particulated solid residue. A quench chamber having a liquid coolant is disposed downstream of the combustion chamber. A dip tube couples the combustion chamber to the quench chamber. The syngas is directed from the combustion chamber to the quench chamber via the dip tube to contact the liquid coolant and produce a cooled syngas. A draft tube surrounds the dip tube such that an annular passage is formed between the draft tube and the dip tube. An asymmetric or symmetric faceted baffle is disposed proximate to an exit path of the quench chamber. The cooled syngas is directed through the annular passage and impacted against the baffle so as to remove entrained liquid content from the cooled syngas before the cooled syngas is directed through the exit path.
