Due to highly endothermic nature of Boudouard reaction, heat has to be continuously supplied in entire reduction zone of rotary kiln.

Direct Reduction Process an overview ScienceDirect

The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted Iron (HBI) and Cold Briquetted Iron (CBI); also Low Reduced Iron (LRI), which is pre
