A system includes a quench ring assembly, which includes a quench ring, a throat ring coupled to the quench ring, and a dip tube coupled to the quench ring. The quench ring assembly is self-retained as a unit. The system also includes a support assembly configured to support the quench ring assembly. The support assembly includes a removable mount.

System and method for gasifier quench ring

In certain embodiments, a system includes a first water supply pump configured to pump water from a gas scrubber sump of a gas scrubber directly to a quench chamber sump of a quench chamber via a first water supply line.

Control system and method to operate a quench scrubber system under high entrainment

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.

A method of assembling a synthesis gas (syngas) cooler for a gasification system includes positioning a dip tube within a shell of the syngas cooler. The dip tube is configured to quench the syngas flowing through the shell and/or at least partially channel the syngas through the dip tube. The method also includes coupling an isolation tube to the dip tube such that the isolation tube is substantially concentrically aligned with, and radially outward of, the dip tube. The isolation tube is coupled in flow communication with a purge gas source and is configured to at least partially form a dynamic pressure seal. The method further includes coupling at least one of the isolation tube and the dip tube in fluid communication with a fluid retention chamber. The method also include at least partially filling the fluid retention chamber with fluid, thereby further forming the dynamic pressure seal.

Method and apparatus for cooling syngas within a gasifier system

A method of assembling a spray quench apparatus is provided. The method includes coupling a first end of an exit tube to a quench chamber such that the exit tube end is in flow communication with the quench chamber, coupling at least one spray nozzle to an opposite second end of the exit tube such that water emitted from the spray nozzle fills the exit tube and forms a film of water across an inner surface of the exit tube, coupling a water source to the quench chamber for providing a substantially continuous water film along an inner surface of the quench chamber, and coupling at least one discharge apparatus to the quench chamber for providing water spray into the quench chamber, wherein the water of the water film and water sprays drains into a water sump.
