Numerical Simulation of Iron Ore Reactor Isobaric and Cooling zone to Investigate Total Carbon Formation in Sponge Iron
Isobaric and cooling zone of iron ore reactor have been
simulated. In this paper, heat and mass transfer equation are
formulated to perform the temperature and concentration of gas and
solid phase respectively. Temperature profile for isobaric zone is
simulated on the range temperature of 873-1163K while cooling zone
is simulated on the range temperature of 733-1139K. The simulation
results have a good agreement with the plant data. Total carbon
formation in the isobaric zone is only 30% of total carbon contained in
the sponge iron product. The formation of Fe3C in isobaric zone
reduces metallization degree up to 0.58% whereas reduction of
metallization degree in cooling zone up to 1.139%. The decreasing of
sponge iron temperature in the isobaric and cooling zone is around 300
K and 600 K respectively.
