Abstract
An enclosure for mounting burners and particle injection equipment in an electric arc furnace (EAF) is described. The enclosures are mounted on the sidewalls of an EAF and include passages in which burners or injectors are mounted so that the discharge ends of the burners and injectors are located closer the melt than sidewall mounted burners and injectors. Burners and injectors mounted in the enclosures heat material in the furnace and deliver particulates to the melt more efficiently than conventionally mounted burners and injectors. The enclosures are liquid-cooled, typically by water, and constructed of high conductivity materials such as copper and/or cast iron and can be constructed in one or more pieces. Therefore, the enclosures protect the burners and injectors from the excessive heat and mechanical impact to which they would normally be subjected when mounted so close to the melt.
