Substantial amount of fumes is emitted during electric arc furnace (EAF) operations at steel melting shop of ASP where three furnaces ofSO T capacity each are available. The EAF roof was provided with a fourth hole to extract fumes generated during operation and discharge through a chimney in the environment.To meet the stack emission norms and a better work-zone air quality, bag filter units
have been commissioned for all the EAFs. While stack emissions are well within the statutory norms after successful commissioning of the dedusting systems, actions
are on for recycling of dust recovered from baghouse to EAFs as briquettes
