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 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...

Beschreibung
Zusammenfassung:	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.
