Described herein is an Improved Converter System designed to help reduce air, land and water pollution by completely converting materials that presently cause pollution into clean burning fuels and a host of other products beneficial to mankind. The primary conversion unit in the system is a zone controlled multipurpose slagging-ash oxygen jet blast converter. All incoming materials are passed through this process computer aided talented offspring of its two ancient prototypes the blast furnace and slagging-ash gas producers and the zone controlled blast furnaces described in U.S. Pat. Nos. 4,381,938, 4,495,054, 3,928,023 and 3,814,404. It employs two sets of tuyeres located in the bosh to input endothermic reacting gases, vapors and dusts through tuyere sets T1 and T2. A 100% oxygen jet blast is also input through tuyere set T2. Three sets of tuyeres in the stack are used to output finished products and by-products, T3, T4 and T5, zone control the stack temperature profile and remove recycling in the stack materials. Incoming solid raw materials are charged in at the top and molten slag and metal are removed from near the bottom as in conventional blast furnace practice. As the burden descends it is completely converted by the precisely controlled as to temperature volume, and composition up moving gas stream. It is originated by combusting in the bosh a more central than conventional portion of the carbonaceous grate with the oxygen jet blast entering through tuyere set T2. It furnishes the heat required to completely convert the downmoving burden to a gas, vapor, molten slag, molten metal or dust. The portion of the gas withdrawn through tuyere set T3 just above the mantel in two modes of operation is an ideal boiler fuel or reducing gas as withdrawn. When it is combusted it produces only water, carbon dioxide and nitrogen, no harmful gases or chemical residues. All other by-products withdrawn or raw materials consumed in other units in the improved converter system producing finished products needed by mankind. Burning in the bosh a more central than conventional portion of the carbonaceous grate with the oxygen jet blast entering through tuyere set T2. It furnishes the heat required to completely convert the down moving burden to a gas, vapor, molten slag, molten metal or dust. The portion of the gas withdrawn through tuyere set T3 located in the stack just above the bosh is an ideal boiler fuel or reducing gas as withdrawn. When it is combusted it produces only water, carbon dioxide and nitrogen, no harmful gases or chemical residues. |
