Cooling chamber assembly for a gasifier

Abstract

The invention relates to a cooling chamber assembly for a gasifier. A gasifier includes a combustion chamber in which a combustible fuel is burned to produce a syngas and a particulated solid residue. A cooling chamber having a liquid coolant is disposed downstream of the combustion chamber. A dip tube is disposed coupling the combustion chamber to the cooling chamber. The syngas is directed from the combustion chamber to the cooling chamber via the dip tube to contact the liquid coolant and produce a cooled syngas. An asymmetric or symmetric liquid separator is disposed proximate to an exit path of the cooling chamber and configured to remove entrained liquid content from the cooled syngas directed through the annular passage to the exit path.

Description

technical field [0001] The present invention relates generally to gasifiers, and more particularly to cooling chamber assemblies for gasifiers. Background technique [0002] In a common coal gasification process in which a particulate carbonaceous fuel such as coal or coke or a carbonaceous gas is combusted, the process is carried out at relatively hot temperatures and high pressures in a combustion chamber. When the injected fuel is combusted or partially combusted in the combustion chamber, the effluent is discharged through a port at the lower end of the combustion chamber to a cooling chamber disposed downstream of the combustion chamber. The cooling chamber contains a liquid coolant, such as water. The effluent from the combustion chamber is contacted with liquid coolant in the cooling chamber to reduce the temperature of the effluent. In some applications, the cooling chamber can be used as a chill chamber for the syngas. In certain other applications, the cooling c...
