Abstract

A down-draft gasification reactor has a solids storage chamber bordered from below by a grate and having an oxidation zone, a product gas collection region disposed beneath the grate, a product gas line for discharging out-gassed product gas from the product gas collection region, a slag-separation device disposed above the grate, and a discharge mechanism downstream of the grate for transporting the separated slag out of the reactor.
