Tunnel kiln is a tunnel-like continuous thermal equipment for sintering process. A tunnel kiln is mainly composed of tunnel-like kiln body and kiln car, with fuel oil, gas, electricity, or coal as the heat source. The kiln walls on both sides of the tunnel kiln passage and the upper kiln roof are built of refractory and thermal insulation ...
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

Coal being the costliest raw materials for sponge iron making and if very high volatile material (VM) coals are used i.e. (fixed carbon) FC/VM ratio is 1 or less, it would be an ideal reductant to react. However, most of the VM in feed coal is lost at the kiln mouth when coal encounters counter flowing hot waste gases.
