An experimental study on the air delivery and gas removal method in a model of furnace for ferroalloy production

Sa？etak In the paper, results of a model study on the effects of the air delivery and flue gas removal method on the intensity of gas blending in the hood space are presented. Two design solutions were compared: with one or two outlet channels for the hood gases. Moreover, two variants of air delivery through charging doors were analysed. The study results show that for technological reasons, more beneficial gasodynamic conditions are obtained when the hood is fitted with two symmetrically located gas outlet channels and the air is sucked through four charging doors
