Thermal Analysis and Energy Efficiency Improvements in Tunnel Kiln

By increasing the temperature of kiln, the thermal energy consumption of tunnel kiln is in an increasing trend. The thermal capacity of the burner installed in the 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, DRI / CBI Production Line using Ore Fins in Tunnel Kiln

As the cost of the coal is 40% of total cost of kiln operat ion so it would be cost effective to chan ge the amount of FCFC and FCIC (details of X10, X11, X12 are provided in Table 1). 𝑋12 33 (10)The overall production process inside the kiln requires a duration of 10-12 hours during which the iron ore is reduced and discharged to a rotary cooler for cooling below 1000C, to prevent reoxidation and effect a better separation of non-magnetic from sponge iron. Since sulfur of coals is picked up by DRI, it should be as low as possibleTSLP Sponge Iron TATA Steel Long Product Limited

1. Less capital cost: The capital cost per tonne of installed capacity, in case of coal-based plants, is 1.8–2 times as high as in the gas-based plants.. 2. High productivity: The throughput rates for gas-based sponge iron plants are much higher than in coal-based plants.The productivity for gas-based plants can be as high as 11 t/m 3 /day as against The pellet plant with a capacity of 7,92,000 MT commenced commercial operations in July 2023. It was set up to reduce any external dependence for pellets.

Production of Sponge Iron through Tunnel Kiln Process.docx

Production of Sponge Iron through Tunnel Kiln Process By Dr S S Bedarkar and Ram Singh India's total production of steel for the year 2009 was about 56.7 million TPA. Out of which almost 40% of the steel is being melted using induction furnace route. Sponge iron or directly reduced iron (DRI) is one of the most important raw materials for Kiln is a prime need in the ceramics industry, where energy loss is a major part which consumes about 60% production cost through thermal energy for different applications. Higher density of fired and tunnel kiln refractory material lowers the thermal diffusivity and the proper selection of fired material minimizes the energy loss along the Thermal Analysis and Energy Efficiency Improvements in Tunnel Kiln
