RDF Fluidized Bed Gasification Systernlo <br />Although this system is described as gasification technology, it does not export a <br />burnable gas' RDF is first prepared using a process similar to the ones illustrated in <br />Figures B-4 and B-5. The RDF (called "wastes" in Figures B-7 and B-8) is then <br />charged to the fluid bed and the gas generated is directed to a secondary <br />combustion chamber, shown above, with molten slag dropping out to a water-cooled <br />sump. The molten slag solidifies into a glass-like material which can be used as a <br />construction nnmteha| or fill. Heat from the gas fired in the combustion chamber is <br />captured in hot water tubes to generate steam which can be used for electric power <br />genonation. Without the generation of usable gas etnaarn and with the necessity of <br />a combustion chamber forgao burn-out, this system is an incinerator. <br />Aga5ifier marketed foryVISVV is built by EnTmoh of Devon, England, as shown in the <br />schematic in Figure B-9. This is a complex system which generates recyclable <br />metals, plastics and other potential revenue streams, in addition to a salable gas <br />(syngas). EnTech provides case studies of nine small-scale facilities in operation. A <br />67TPO facility operates on a mixture ofMSVV. <br />u`Source: Ebara Corporation, Tokyo. <br />GB8/C08027-01 B-11 August 15,2OO8 <br />
