It enters the kiln at atmospheric temperature and thus, considered as it is in the model. (3) Generally, the outlet stream of the kiln consists of 82%, 10%, 0.7% and 7.3% sponge iron, char, spent lime and ash, respectively. As the amount of sponge iron is significantly high in the outlet stream of the kiln it is considered as purely sponge iron.
