Coal Based Tunnel Kiln Process In India

SPONGE IRON PRODUCTION FROM ORE -COAL

2014-9-2  Abstract: Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal. However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process.
