kiln to the lower end of the kiln. The thermal profile required to produce the dead burn product is achieved by burning a solid fuel with a high fixed carbon (FC) content which produces a long, thin flame during combustion. This flame type is achieved by firing petroleum coke and anthracite coal or natural gas. The physical and chemical process at
Aug 07, 2018· Carbonaceous Materials and Characterization Thereof. Although only coal (which is less expensive than, e.g., coke and anthracite) is currently used as PF to fire pre-reduction rotary kilns, a wider selection of materials was included in this study to assess if the developed method would be applicable for a wider selection of carbonaceous materials.. These materials consisted out of twenty ...
A process is disclosed for gasifying solid coal particles in a rotary kiln that produces simultaneously and continuously two distinctly different fuel gas streams from the opposite ends of a single kiln. A relatively low temperature gas is discharged from the solids inlet end of the kiln, which contains substantially all tars produced by the process.

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.
The kiln is 20 meters long and 2.4 meters in diameter. Raw material is continuously fed from a hopper into the rotary kiln which steadily turns the carbonized material inside. As a blower forces air into the kiln, the charcoal reacts with hot steam causing the internal temperature to rise to 900-1100ºC.
