Abstract

The fixed-bed gasifier and method in accordance with the invention operates with a solid material batch that is perfused by air and/or steam in opposing direction. Compared with the resultant pyrolysis coke batch, the actual pyrolysis zone is thin enough so as to result in a material dwell time in the pyrolysis zone of only a few minutes, while the dwell time of the pyrolysis coke in the pyrolysis coke layer may last up to several hours. The pyrolysis occurs in an allothermic manner. High-energy low-dust and low-tar gas is formed. The process control can be automated in a reliable manner. The exhaust of reaction gases and pyrolysis gases occurs through the heating chamber, whereby the last tar components are eliminated.
