摘要:The present invention provides a relatively small scale apparatus for gasifying solid fuel in which pyrolysis gas produced in a pyrolyzer by thermal-decomposition
reaction of the solid fuel can be reformed to crude fuel gas. The apparatus comprises a
solid fuel pyrolyzer 1 and a steam reformer 5, and thermally decomposes the solid fuel with a combustion reaction of a low oxygen density to produce the pyrolysis gas, and reforms the pyrolysis gas to produce the crude fuel gas. The pyrolyzer has an air inlet 18 positioned at a bottom part thereof and upwardly blowing combustion air into the pyrolyzer; a bed of pyrolyzer 30 located above the air inlet; and a pyrolysis gas exit positioned at an upper part of a body of the pyrolyzer and conducting the pyrolysis gas out of the pyrolyzer. The bed is made by a layered stack of many spherical heat-resistant materials 32 which form a number of narrow gaps for draft of the combustion air over the whole bed. The steam reformer has a reforming area 51 which produces the crude fuel gas by a steam reforming reaction of the pyrolysis gas, a pyrolysis gas inlet 55 which is in communication with the pyrolysis gas exit and which introduces the pyrolysis gas into the reforming area, a mixed gas inlet 54 introducing mixed gas of steam and air into the reforming area, a reformed gas effluent passage 70 for conducting reformed gas of the reforming area out of the reformer, and a permeable heat-barrier 60 positioned between the reforming area and the reformed gas effluent passage. The barrier is made by a layered stack of many spherical heat-resistant materials 62 which form a number of narrow gaps for draft of the pyrolysis gas and the mixed gas.
