A METHOD FOR GENERATING PRODUCER GAS FROM STRAW AND LIKE MATERIALS, AND APPARATUS FOR CARRYING OUT THE METHOD

摘要

According to this invention producer gas is manufactured from a straw-chip fraction obtained from crude straw. The straw-chip fraction is introduced into a pyrolysis space or chamber (13) together with primary air heated to at least about 400°C, therewith to engender so-called flash pyrolysis. The resultant gas, together with contaminants, is passed down through a dolomite bed in a tubular reaction vessel (8) in which reduction of carbonized flakes takes place and the tar present is converted to combustible gas form.
