✦ Synopsis

An annular chamber provided with local ore feed and discharge as well as peripheral burners and a gas-transfer system is included in the rotaryhearth furnace for ore treatment.

The CO-rich atmosphere from coal combustion is applied for the reduction of the ore and recirculated in the furnace for secondary combustion with heat recovery and decreased pollution in discharge.
