PROCESS AND APPARATUS FOR THE PREPARATION OR SYNTHESES GAS

摘要

Process and apparatus for producing synthesis gas by partial combustion of carbon-containing fuel with oxygen-containing gas in a reactor in which slag is removed through a slag discharge in the bottom and passed by gravity into a water bath where it is cooled by water. The steam which is produced is first used to cool the slag and is further used as an additional quench gas. A quench medium is contacted countercurrently with the slag leaving the gasifier.
