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.

A gasification assembly that includes a quench chamber and downstream transfer piping is disclosed. The gasification assembly includes the quench chamber and a liquid coolant disposed therein, and a dip tube that is configured to couple a combustion chamber to the quench chamber and also configured to direct syngas from the combustion chamber to the liquid coolant and produce a cooled syngas. The assembly further includes a transfer pipe that is in fluid communication with the cooled syngas and configured to transfer the cooled syngas to a downstream scrubber component. The transfer pipe further includes an excess moisture removal device, which is configured to remove moisture from the cooled syngas.

A stator-rotor assembly is described, including at least one interface region and a gap between a surface of the stator and a surface of the rotor. The stator is a nozzle or vane that includes circumferential endwalls. Each endwall includes at least one leading edge and one trailing edge, relative to a hot gas flow path. A trailing edge of at least one of the endwalls includes a pattern of cavities that are capable of impeding the entry of hot gas into a wheelspace region that adjoins the gap between the stator and the rotor. The cavities can also be formed on various sections of the rotor. The stator-rotor assembly can be incorporated into various turbomachines, such as gas turbine engines. Related processes are also described.

Gasification cooling systems provided herein may include a housing having a fluid passage extending in a flow direction lengthwise along the housing and an annular wall disposed about the fluid passage and having one or more annular steps. Such systems may also include a plurality of heat exchanger tubes downstream of the one or more annular steps and adapted to cool a syngas in the gas passage as the syngas flows in the flow direction.

Embodiments of gasification cooling systems provided herein may include a housing, an annular wall, and one or more tangential fluid jets circumferentially disposed about the annular wall. The housing includes an inlet, an outlet, and a fluid passage disposed between the inlet and the outlet. The annular wall is disposed about the fluid passage, and a fluid stream is configured to flow in a flow direction from the inlet toward the outlet. The one or more tangential fluid jets are adapted to inject fluid into the fluid passage to annularly circulate the fluid stream throughout the fluid passage as the fluid stream flows in the flow direction.

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.

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.
