Abstract:
A stackless waste material renewal process utilizing an oxygen enriched gas, comprising the steps of:providing a thermal decomposition-melting furnace; providing oxygen enriched gas to said furnace; providing waste material to said furnace at an upper portion; burning said waste material in the furnace in such manner that all organic substance contained in the waste material is partially burned-thermally decomposed and discharged to an upper side of the furnace as a thermal decomposition gas while all inorganic substance contained in the waste material is melted and discharged to a lower side of the furnace to be granulated; purifying the thermal decomposition gas and reclaiming waste water such that whatever amount of hazardous substance remains in the thermal decomposition gas is neutralized and further processed to produce a purified gas process water; producing by-products, by completely burning said purified gas through catalytic combustion to produce carbon dioxide gas and catalytic steam reforming said purified gas to produce a synthetic gas, and re-utilizing said carbon dioxide and said synthetic gas to produce secondary products.
