Abstract
A three-dimensional model was developed to simulate the gas flow distribution in COREX C3000 shaft furnace, and the effect of horizontal gas distributor (HGD) on gas distribution analyzed. The results showed that HGD increased the contact area between reduction gas and burden, so that the pressure difference was decreased significantly. HGD could also increase the gas velocity at the bustle pipe level, yet in the upper zone there was no obvious change of gas velocity, and the dead volume of gas flow in the lower zone was enlarged. HGD could commendably guide reduction gas into the central region of furnace, and had primary restraining effect on the volume of scurry gas. The volume fraction of scurry gas was decreased from 12.23% without HGD to 8.29% with HGD.
