Raw material utilization and waste generation for the DRI suggest that tonnes of ore, tonnes of noncoking coal and tonnes of dolomite are needed to produce 1 tonne of sponge iron and tonnes of solid wastes [2, 5].This implies that for every 10 tonnes of sponge iron produced, almost 2 tonnes of solid wastes are produced in the form of semiprocessed iron and coal char.

Most of the Indian DRI plants use coalbased processes due to less investment, lowergestation period, easy availability of coal, and limited accessibility of gas. The overall capacity utilization of the DRI plants stands low, at about 60%. The poor quality of iron ore further results in lower yield of the sector.

The solid product is known as direct reduced iron (DRI) whereby the slag remains in the product. DRI processes can be broadly divided into reactor type, namely rotary kilns (SL/RN) and rotary hearth furnaces (Fastmet and ITmk3). Smelting reduction processes that use coal as both a reductant and a carbon source.

A Case Study on Accretion Formation in Rotary Kiln of DRI Process

In coalbased DRI process, accretion formation inside the rotary kiln is a genuine complex problem. Accretion formation in a rotary kiln of 100 tpd DRI plant has been investigated. The nature of accretion formation with respect to the charge burden and operational parameter have been discussed. High ash content in the coal and excess use of dolomite lead to accretion formation. Two different ...
