Description:
The study describes the state-of-the-art of controlling fumes escaping from blast furnace cast houses. Background information is based on: a study of existing literature; visits to blast furnaces in the U.S., Japan, and Europe; meetings with an ad hoc group of experienced blast furnace operators and engineers appointed by the American Iron and Steel Institute; and a questionnaire sent by AISI to all its members (the questionnaire resulted in operating and physical characteristics data on 151 standing blast furnaces). The limited emissions data available at the start of the study had been obtained through the use of various rather imprecise methods. To obtain additional more precise data, approval was obtained from Dominion Foundries and Steel, Ltd., to sample emissions from its No. 1 blast furnace cast house using EPA sampling methods. (This furnace employs full emissions control using a total cast house evacuation technique.) Existing cast houses were classed according to major factors influencing control scheme selection. For yet-to-be-design cast houses, suggestions are made for optimizing the integration of cast house emission control. For both retrofit and new classes, technology gaps are identified and the nature and scope of suitable development programs are proposed to fill these gaps.
