Abstract (en)

The installation is intended for iron or reduction with coal, and includes a rotary hearth (1) serving for accommodation of iron ore and coal in any form and mixture. The hearth is covered by a hood which is provided with burners (2) directed onto the hearth. Waste gases (or used heating gases) are leave the furnace through outlets (3) under the hood. These outlets are positioned between the burners in such a way that mixing of the waste gases with fresh heating gases from the burners is avoided. The distances between the burners and the gas outlets are chosen to allow the useful energy of the heating gases to be transferred to the process before they leave the furnace
