Tunnel Kiln | SpringerLink
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 / CBI Production Line using Ore Fins in Tunnel Kiln
The Production Line of Sponge Iron (DRI) using Iron Ore Fines and Coal Fines using Tunnel Kiln is the latest way, (though the Oldest one 1905) but becoming popular these days, because of the advantages it has over the Rotary Kiln, which is as follows: 1) Low Project Cost. 2) Low Maintenace. 3) Longer Kiln time as no accretion, so no shut-down ...
