Abstract
A pollution control system for electric arc furnaces includes fume collectors disposed at one side and above the furnace and pairs of blower nozzles mounted on an overhead crane used to deliver feed materials to the furnace. One nozzle of each pair is adjustable in a vertical plane and the other nozzle of each pair is adjustable in vertical and horizontal planes so that the nozzles may be positioned for blowing furnace fumes into the fume collectors when the furnace roof is elevated for charging, during furnace operation and when the furnace is tilted for tapping.
