| titleOfInvention | Process for upgrading iron ore pellets |
| abstract | PROCESS FOR UPGRADING IRON ORE PELLETS Abstract of the Disclosure In a process for hardening oxidizable green iron ore pellets in a horizontal grate or a circular grate furnace, said process comprising passing the grate with a bed of pellets thereon along a horizontal path through the furnace wherein said pellets are heated by contact with hot gases, the furnace having a zone in, or downstream of, the area where the peak temperature of the furnace is attained in which zone the average pellets temperature is in the range of about 1100°F to about 2200°F and in which zone the flow of gases is in a downward direction towards the pellets on the grate the improvement comprising: (a) covering the periphery of at least part of the zone with at least two hoods to provide a hooded area on each side of the top of the grate under which the periphery of the grate passes; (b) passing at least one oxygen stream within each hooded area in such a manner that the stream flows in a downward direction towards and through the periphery of the bed of pellets on the grate passing through the hooded areas; (c) passing the periphery of the bed of pellets on the grate through the hooded areas in such a manner that the residence time of such pellets in the hooded areas is at least about 5 seconds.
