Fine fuel gasifier - with swirling flow dust extractor in upper part of reactor

摘要

A gasifier for fine-grained fuel includes in the top part of the reactor a dust extractor, designed on the swirling flow principle in which the gas to be dedusted rises in an ascending vertical spiral. The unburnt particles are sepd. by a descending spiral of a sec. coolant gas. . The gasifier includes a shaft-type reactor in its lower part, and a swirling-flow dust extractor in its upper part. A carrier gas introduces the fuel through nozzles at the bottom. This gasifier has a simple design. It takes up little space and its operating costs have been reduced to a min..
