Abstract
The hot partial oxidation gases which are formed in a gasifier for solid or liquid fuel are passed first into a dust separator under conditions where 70 to 95% of the impurities are eliminated, whereupon the gases then are washed in a wet washer with an amount of water not higher than necessary to remove the residual dust impurities. The process has the particular advantage of a very low amount of drainage water and has a high safety factor and adaptability for different conditions.
