KilnSimu – Rotary Kiln Simulator
Most kilns operate in the counter-current mode, i.e., the condensed material is fed into the kiln from the cold 'feed end', and is then processed to reacted product by heat transfer from the surrounding hot gas, which is introduced into the kiln from its hot 'burner end'. The final material product is removed from the hot end.
Model and simulation of heat transfer, magnetite oxidation …
A numerical model was developed to simulate the combined effects of heat transfer, magnetite oxidation, and NO{sub x} formation in a grate-kiln furnace for taconite pellet induration. Heat transfer from the flame in the kiln was described by the net radiation method. The shrinking core model was used to account for magnetite oxidation on the grate.
