Methods and apparatus to facilitate cooling syngas inside a gasifier

摘要

A method of cooling syngas in a gasifier (200) is provided. The method includes channelingcooling fluid (308) through at least one platen (320) that extends at least partiallythrough a reaction zone (228) of the gasifier, and circulating reactant fluidaround the at least one platen to facilitate heat transfer from the reactant fluidto the cooling fluid.
