Wallace, D., C. Cowherd, AND Jr. FUGITIVE EMISSIONS FROM IRON FOUNDRIES. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-79/195.
Description:
The report describes the assessment of fugitive emissions of air pollutants discharged from process operations in iron foundries, and the need for the development of control technology for the most critical sources. Data indicates that the most significant fugitive emissions control problem in foundries is the pouring of hot metal into sand molds and the subsequent cooling of castings of these molds. Other significant fugitive emissions sources which have control problems are the electric arc furnace, preparation of molds and cores using organic binders, and casting shakeout. These conclusions are tempered by the fact that, for most fugitive emission sources in iron foundries, data is insufficient to determine accurate emission factors. Research and development programs are recommended: to better quantify the most significant sources; to evaluate currently available control technology for electric arc furnaces and shakeout; and to develop new control technology for pouring and cooling and for core and mold preparation using organic binders.
