Abstract
Control of fugitive emissions is an ongoing problem in the steel industry. High emissions are generated during scrap charging, refining and tapping operations. These emissions take the form of both fine particulate (with most particles less than 10 microns in size1) and gas, which is collectively referred to as fume. The particulate is composed of iron oxides, soot and kish (graphite flakes). The gaseous emissions are composed of combustion product gases and unburned hydrocarbons. The hot, buoyant fume forms plumes that rise and disperse the contaminants throughout the building. Inadequate control of emissions leads to both poor air quality in the shop, exposing workers to unacceptable contaminant levels, and release of emissions to the environment.
