Sep 01, 2015· In conventional coal based sponge iron plant, Fig. 1, kiln feed (Stream no. 1), which consists of iron ore, feed coal and dolomite, is fed to the rotary kiln (RK).A separate conveyor collects different size fractions of coal (Stream no. 5) for injection into the kiln with the help of pressurized air (Stream no. 4) from discharge end side.
Iron ore and non-coking coal are the prime raw materials for the production of sponge iron. These are charged into a rotary kiln in requisite proportion along with some dolomite. Coal plays a dual role in the process by acting as a reductant as well as a fuel for providing heat to maintain the requisite temperature inside the kiln at 950-1050 o C.

Tunnel Kiln Process Sponge Iron In India - syssla. Machine Praktijkunicnl. Tunnel Kiln Coal Based DRI Plant Electrotherm India. Production cost from Tunnel Kilns is lower than that from rotary kilns Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because while the input raw material gets just about 24hours for the reaction ...
Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because, while the input raw material gets just about 24hours for the reaction, the figures almost reverse in case of the Tunnel Kiln.
The sponge iron is produced in the form of lumps as well as fines. The production of sponge iron depends on metallization of iron ore. Fig. 1. Schematic of rotary kiln For the present work data of a typical industry of 527 T/day production capacity is collected for 25 days. The data of temperature T-1 to T-12, AT-1 to AT-3 and MF-1 and MF-2 are ...
Market share: About 23% of sponge iron total production. 4) Tunnel furnace process . This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent. Natural gas generates the required reduction temperature, and reduction is performed on Silicon Carbide (SiC) Crucibles in a tunnel furnace.

Online Chat Modelling And Optimization Of A Rotary Kiln .
Jul 29, 2010· Lump iron ore in the size range of 5-20mm can be used in all coal based rotary kiln processes. In gas based processes 70% iron ore pellets and 30% lump iron ore of 10-30mm are being used. In general high grade iron ore of 65% minimum Fe (total) with less decrepitating characteristics is preferred for use in rotary kiln. Reductant:
In the coal based DR Process, the reducing gas is produced from non coking coal in the reduction zone of the furnace, typically a rotary kiln. Sponge iron plants The typical examples of coal based ...

Coal based Direct reduction process is classified based on the reducing agent namely solid. Most solid reduction process use non-coking coal as reducing agent due to abundantly available non-coking coal. The process proposed to be adopted is the rotary kiln proposes using Non-coking coal and iron ore.
