First developed the concept of the EAF off-gas aspiration system, based on combined gas-dynamic impact of dispersion and increase the suction surface of the exhaust duct with its approach to the region of electrodes holes,which reduces: fugitive emissions in the electrode gaps by 15-29%, dust removal from the EAF by 20-50%, air inflow in the slag door by 20-25%. The investigation and optimization of scrap preheating by the EAF exhaust gases is fulfilled in order to increase furnace energy efficiency while avoiding the formation of highly toxic PCDD/F, which provides savings of 25-30 kWh/t at 50% charge mass preheating.
