PROCESS AND APPARATUS FOR SLUICING RESIDUES FROM THE PRESSURE SYSTEM OF A PRESSURE GASIFICATION TANK

摘要

This invention relates to a process and an apparatus for sluicing residues produced by the gasification of carbonaceous ash-containing, especially solid, fuels such as coal, brown coal, lignite and other carboncontaining substances with oxygen-containing compounds such as water and/or carbon dioxide. The reaction of the feedstock is carried out at a pressure of 10 to 200 bar. The gasification residues leave the gasification chamber in a liquid or plastic state and are converted, in a water bath connected to the gasification chamber, into a solid granulate which may also be fine grained. The granular residues are periodically discharged from the pressure system of the pressure gasification plant by means of a lock vessel filled with water and arranged beneath the water bath.
