Multimedia Environmental Assessment of Electric Submerged Arc Furnaces Producing Ferroalloys

摘要

The report gives results of sampling and analysis at five ferroalloy plants to determine the amounts of particulates and organics generated during manufacture of several products, the effect of furnace type on the amounts generated, and the amounts of these materials escaping to the environment. Samples were also taken of the influent to and effluent from two plant wastewater treatment systems and groundwater samples around the waste disposal area of one plant. More organics are emitted to the atmosphere than particulates. Open furnaces emit as much as or more organics to the atmosphere than do semi-enclosed furnaces (kg/MW-hr basis).
