Looking forward to the need of developing coal-based sponge iron technology in India, a country having no significant resources of either coking coal or natural gas, the Research and Development Division of the Tata Iron and Steel Company Limited (TISCO) set up a rotary kiln based direct reduction pilot plant in 1975. In this pilot plant, a totally …

Coal based direct reduction process is based on the solid reducing agent which is non-coking coal. The reaction takes place at high temp (1000 deg C to 1100 deg C). Coal plays a dual role in the kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temperature.

TATA Sponge employs coal fired rotary kilns to produce sponge iron. Iron ore, coal, and dolomite are charged from one end of rotary kiln (schematic diagram in Fig. 1), and the …

In Kiln 3 at Tata Sponge Iron Ltd, eleven thermocouples are inserted through the shell along the length of the kiln to record the kiln bed and gas temperatures. It should be …

This document contains the resistance readings of the elements for all KilnMaster Kilns. It is important to note that these readings are, in most cases, the resistance readings of a section of a kiln and not a single element alone. We do not publish our individual element readings. This information is helpful in determining if at least one of ...

The product gases from coal-fired sponge iron kilns exit at a high temperature (800-950 o C) and contain some unburnt carbon and carbon monoxide along with nitrogen, carbon dioxide and entrained dust.

TATA sponge has three coal-fir ed rotary kilns for the production of sponge iron. The rotary kiln is comprised of a rotating cylindrical shell having a length of 80 m and an internal diameter of 4 m.

rotary kiln based processes is of obvious interest. With this in view, the Tata Iron and Steel Company Limited (TISCO) installed a pilot plant with a rated capacity of 12 tonnes per day, t'2 which has been in operation since early 1975. A number of experimental campaigns have been carried out in

The Tata Sponge Iron Odisha plant began operating in 1982. It expanded its capacity in 1990-1991, 1999, and 2006. The plant was originally designed with a production capacity of 90 ttpa which was enhanced to 120 ttpa through various modifications during 1990-91. The capacity was doubled by adding an additional kiln in 1998-99.
