Live Chatuser, where all the processes that occur in the kiln are simulated. These processes are: heat and mass exchanges between the different volumes during the combustion reaction, and the different phases inside each volume (solid, gas and moisture) (Shin and Choi, 2000). The model simulates all heat exchanges for radia
Live ChatNoncoking coal is required in sponge iron production, since the coking reaction leads to formation of rings inside the kiln. Practically permissible caking index is 3 maximum for rotary kiln operations. 2) Low ash contents: High ash leads to under utilization of the kiln volume available for reduction.
