Casthouse emission control system, No. 3 blast furnace, US/Kobe Steel Co

During blast furnace casting operations, hot metal generates fume and particulate emissions. Environmental regulations require that blast furnace casting emissions be controlled. The casthouse of the No. 3 blast furnace at USS/Kobe was completed redesigned and rebuilt during modernization of this facility. A state of the art casthouse emission control system, consisting of hoods and covers evacuated via ductwork to a fabric filter systems, was designed and installed as in integral part of the casthouse. Casthouse operations and maintenance, and environmental performance were foremost in the design considerations. This paper discusses the design, operations and results of this newly operational system along with some key permit issues that were addressed with the EPA.
