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

In coalbased DRI plants rotary kiln is used for the reduction of iron ore. Accretion rings formations inside the kiln adversely affect the performance of plant in terms of low production and inferior quality, which frequently lead to shut down. About 70% of the coalbased DRI rotatory kiln shut down is due to the accretion formation [1]. Lit
